Bazooka BTA6100 BT Series 6-Inch 100-Watt Amplified Tube Subwoofer List Price: $199.95 Sale Price: Too low to display |
|
As all-in-one solutions go, you simply can't beat the A100 Amplified Bass Tubes by Bazooka. Designed to be a simple-to-install yet effective upgrade to your car's existing mobile audio system, the A100 Bass Tubes feature a 100-watt, 2-channel amplifier built right in, coupled to a dual voice coil woofer. Since the amplifier has a built-in crossover to remove the high frequencies that the woofer cannot play from the signal, you get exactly what you need in the A100--crisp, clean bass and nothing more. When connected to your system, the end result is seamless integration, both electrically and audibly, yielding sound quality that your factory system simply can't touch. Crisp, clean bass and nothing more. Click to enlarge. The Bazooka Bass Tubes enclosure is optimized for corner loading. Click to enlarge. The corner of your car amplifies the concentrated bass output of the Bass Tubes enclosure. Click to enlarge. BT Amplified Bass Tubes The new amplified Bazooka subwoofers feature the legendary patented Bass Tubes enclosure design, but with a twist. These units are completely self-contained bass monsters. Available in 100-watt BTL or 250-watt Class D amplifier configurations, the new amplified Bazooka subwoofers are the true solution to the common automobile interior problem of "not enough space for bass." A Bazooka subwoofer adds the bass, clarity, and realism that your system is missing with absolutely no modifications to your car, its warranty, or its original audio system. If you are leasing your car, there is no better way to upgrade your stereo system than by adding a Bazooka subwoofer. BTA6100 The BTA6100 features a 6-inch dual voice coil subwoofer and fits in places most subs can't. The 6-inch works great behind the seat of small trucks, the trunks of sedans, or hatchbacks. Simply point it into the rear corner to take advantage of the Bass Tubes enclosure, and you're rockin' in no time! The Bazooka subwoofer's patented Bass Tubes bass-reflex enclosure design allows for use of 100% of the woofer's cone area. Inch for inch, it will outperform most boxes. The Bazooka Bass Tubes enclosure is optimized for corner loading, and its port and woofer are on the same plane and in close proximity for maximum corner-loading results. And, just like a megaphone amplifies a cheerleader's voice, the corner of your car amplifies the concentrated bass output of the Bass Tubes enclosure. Its advantage is that it fits any vehicle: the perfect fit for a perfect sound. As with all Bass Tubes Enclosures, the BTA6100 comes with straps to keep the sub securely mounted, while still making removal quick and easy if you need even more cargo room. Bazooka Add-ons Use Bazooka's F.A.S.T. harnesses to make installation even easier. They're a simple way to protect your vehicle's warranty by making installation a plug-in process. The T-shaped harness has three ends: One plugs into your car's OE radio, one plugs into the plug you removed from the OE radio, and the third end runs all the way back to the rear of the car and plugs into your A100 Bazooka subwoofer. Great for leased vehicles, the F.A.S.T. systems are available for most popular cars. Bazooka's RBCM-100 Remote Bass Control Module allows you to control the amount of bass from the driver's seat. Optional Chrome-Plated UMS Brackets give a flashier look, as well as a more secure, permanent mounting when removal isn't a problem.

Here are some more information for Crew Radio System:
Having the right knowledge on film making might help you run a studio or be a goof studio executive, but to become a successful independent film maker, you need have that special awe. In order to become a good producer, you must develop certain skills in you as an individual.
The top 5 requisites among the rest are as follows:
1. Organization
This is perhaps the most important skill required for a producer. Some of you might be organized enough, but you would all agree that this skill can not be taught to anyone neither can one learn it that easily. It is just about trying and getting it in to your system with practice. In case you keep forgetting the place you left your wallet at or are still calculating as to when did you last change the oil of your car, you certainly need to work in this area. Try reading some self help books like - How to get organized. There are many training sessions that could give you easy and effective tips on being organized. Pick you method your own way, but do get organized as being a producer this is a basis necessity for you.
2. Quick Decision Making
An individual's ability of making quick decisions is indeed helpful in several fronts of life. When it comes to film making, the actions and procedures are quite planned and hence predictable regarding the results, yet the field of film making is full of surprises. There are several gray areas that keep on forcing last minute changes in your plans. Being the producer, you would be the captain of the ship with all the onus for good or bad coming back to you. This would call for many decisions to be made right now with no time to think.
In order to develop this skill within your self, first of all realize thoroughly the since the beginning until the end you are responsible for all the decisions taken during film making. Any mistakes that follow can not be blamed on anyone else, but you, the producer. You must have the power to judge when your decisions have gone wrong. Being a film maker, it is a must for you to be decisive and accept the blame when ever necessary. Remember you are the role model for your crew & cast and they would follow what ever you say.
3. A Good Negotiator
All the decisions you make regarding the expenditure of the film would be final. You must understand that without negotiation, if you continue paying the prices quoted always, you shall far exceed your stipulated budget which is not something truly advisable. As a producer it is your duty to know the maximum price you could pay for any item as per your budget. Then try negotiating the bid by 20-30 percent. If it doesn't work out, make it a point to say no, but do not exceed your budget in any circumstances.
4. Diplomacy
A producer needs to manage a big group of talents and the crew. Hence, you must keep a close watch on the gossips and rumors. When you become a part of some feuds and conflicts, work out a remedy for the situation with out taking any sides. This is art you would need to master as you would use it every working day.
5. Energetic
A producer must be very energetic in order to face the hectic schedules every day. While a lot of you may think that consuming caffeine in the morning wakes you up fresh, remember a producer needs to have some real energy to face the bilk of challenges that come across during the process of film making. So, you must eat well & have lot of vitamins to avoid any break downs during the long working days.
Mastering these 5 basic individual skills, would make you a real successful film producer. Yet, applying your knowledge on film making to the fullest is a pre-requisite to become an independent film maker.

Push To Talk vs. Two Way Radios
Push to talk is often confused as being the same thing as a two way radio. While it is true that two way radios use push to talk communication (think walkie-talkies), push to talk or PTT is a feature that can be added on to a cell phone plan for use on your cell phone. Two way radios on the other hand, are simply two way radios, with no additional features.
Two way radios have utilized the push to talk feature for decades in a variety of settings. Until recently, two way radios have been used primarily by industrial type workers, emergency crews, and utility companies. And although the communication takes place on a secure channel, the conversation is not necessarily one kept under a shroud of privacy. When using push to talk through your cell phone provider, the communication can be as private as a regular cell phone call.
Using push to talk is much like the old days of playing with walkie-talkies with your friends around the neighborhood. Only now, when push to talk is used as an additional feature on your cell phone, it has the capability of maintaining communication to national, and international customers. And instead of crackly, indecipherable conversations as was typical with walkie a talkie, the reception with push to talk is as clear as a standard phone call.
A perfect example of the benefit of using two way radios is in an emergency situation. An emergency dispatcher using a two way radio has the ability to communicate with and dispatch an officer to an emergency while maintaining contact with an emergency caller. The officer dispatched to the emergency can communicate with the dispatcher on his way to, and at the scene of the emergency with the touch of a button. If a cell phone were used in an emergency situation rather than a two way radio, critical time could be lost waiting for a cellular phone connection. When using two way radios, communication between users is instantaneous.
The way push to talk works through your cell phone is fairly simple, like using walkie- talkies; only radio IDs similar to phone numbers are designated for specific users, allowing for the privacy of a cell phone conversation. Here is a simple guide to using your push to talk phone:
• Enter the radio ID of the person you want to contact
• Push down and hold the push to talk button on the phone. When a specific tone is emitted, usually resembling a beep beep sound, the call is clear and ready to be made
• You are connected! Be sure to hold down the push to talk button while you're talking.
• When the other person is ready to talk, let go of the talk button and wait for their response.
• Wait until you hear the tone indicating it's clear to talk, then push and hold down your talk button to respond.
• When you're finished, push the talk button again, and the call is complete.
As with any service, there are pros and cons to using the push to talk service. Although it is estimated there are currently 20 million (and growing) push to talk customers, not everyone in your address book is likely to be available through push to talk. This limits the number of personal calls you will likely be making through push to talk. If however, this is something that will be used for a specific business related purpose, and everyone you need to talk to is guaranteed to be in the push to talk network it can be amazing.
Imagine an event such as a rock concert in a large stadium, with several outlying parking lots and hundreds of events staff. Using push to talk communication, calls can be made from one event staff to another, (one to one) or from the head of the event to all 200 employees (one to many, often called group push to talk). Instantaneous communication at a huge event, with multiple employees could potentially eliminate any number of unforeseen complications.
This expediency in communication is easily translated to any number of industries. In a situation such as a major metropolitan power outage, utility workers can have the capability of communicating between one another even while regular modes of communication are out, even cell phone towers. In a situation such as this, the coverage area is more limited, reaching a few miles rather than across state lines. Nevertheless, this type of communication is perfect for a power outage, enabling utilities and utility workers to restore utility services while maintaining communication with one another. Some carriers even have the ability for users of their networks to use the push to talk functionality off-air. This means users working in very remote areas where cell towers are unable to reach, such as logging companies working deep in wooded areas, can still use the radio functions to communicate effectively and instantly to one another on the same carrier's network.
Yet another benefit of push to talk is that it isn't cost prohibitive; minutes used across push to talk networks aren't deducted from monthly cell phone minute allotments. A basic plan for push to talk can be purchased as an additional feature for a regular cell phone. A plan with unlimited minutes between push to talk customers is around $9.99 on top of a regular cell phone bill. Family plans can be purchased for push to talk groups, starting at $19.99/per month. In addition to this benefit is that of international communication capability. With an international talk plan, calls can be made across international boundaries without the hassle of extremely high rates.
As opposed to regular cell phone conversations, push to talk is perfect for immediate, brief conversations. This feature is ideal for business meetings, or something as simple as instant communication between two spouses in a crowded grocery store. Push to talk phones are also cropping up all at amusement parks across the country. Teenagers can split up across an amusement park while maintaining contact with parents, all without deducting minutes from a monthly cell phone allotment or incurring roaming charges when out of network.
As with any type of communication, there are a few drawbacks when using push to talk services. One such disadvantage is that nuances of a regular conversation are lost as only one person at a time can talk while the other listens. This is especially true because there is a bit of a lag in time between communications, making the conversation seem a bit stilted. Another drawback is how obnoxious this type of conversation can be in a public place. Not only does someone within the vicinity of the call have to listen to your side of the conversation, they have to listen to the other end as well. Considering the current lack of cell phone manners, this adds an entirely new level of etiquette and privacy concerns.
Another drawback of using push to talk instead of a standard two way radio is the monthly fee attached to your cell phone bill. A two way radio can be purchased for a one-time cost of anywhere from $20-$250, while a push to talk cell phone customer can pay $9.99/per month up to $19.99/per month for similar features.
There are several differences between the push to talk feature of a cell phone and two way radios. Each has unique benefits and drawbacks catering to specific ranges of customers. A two way radio is a great device to stay in contact with your 14-year-old while visiting an amusement park. It's doubtful however that you would want to give the same 14-year-old unlimited access to your push to talk cell phone.
It seems likely that although there are a limited number of customers currently connected to the cell phone push to talk network, it's only a matter of time before that changes. While Nextel was once the only provider of this service, almost all other cell phone networks either currently offer services, or have plans in the immediate future to do so. Although it was once the stand alone feature differentiating Nextel from other networks, this is no longer the case. SouthernLINC Wireless, AT&T & Verizon all offer push to talk packages, and other networks are not far behind. Just as text messaging was once a rare cell phone feature, now it's hard to imagine anyone buying a plan without it.

WW2 Tank design. and little 17 Pounder Gun HE round question.?
If say I designed a 4 man Tank during WW2 with a Driver (no assistant driver/hull machine gunner as space would be used for ammo.) Gunner operating a primary weapon, either a 17 Pounder or US 76mm or 90mm and 2 coaxial guns with different adjustable mounts for either (X1) Browning 1919 7.62mm M.G and (X1) 20mm Hispano Autocannon or (X1) Browning M1919 7.62mm M.G and (X1) .50 Cal M2 Browning hb or (X2) Browning M1919 7.62mm M.G .Loader reloading primary and secondary weapons and a commander comanding with an additional A.A Browning M1919 7.62mm M.G on commander's cupola. My question is who would operate the radio system, would it be to much for the loader, or to much for any other crew member? what would you do? My last question is about the 17 Pounder gun. Until late 1944 the 17 Pounder didn't have a decent High Explosive round. Before the new HE round was produced did they have (although not vey good) a HE round to use in the meantime. Cheers John
I've never been a big fan of 20mm co-ax weapons. Nobody who has tried it seems to have had success with it. 12.7mm OTOH....
In a 4-man tank the tank commander would function as the radio operator. Often he did in 5-man tanks as well. It depends on the tank and the doctrine of the user. This is as it should be anyway because having someone other than the tank commander communicate with other vehicles in formation and/or higher echelons only invites delays and communication errors. External machine guns should be mounted so that either the loader or both the loader and commander can operate them. Ideally both would have their own.
Before September 1944 the 17-pounder has a nearly useless HE round that was produced in very small quantity - only something like 20,000 rounds IIRC. A big reason only 1 Sherman Firefly was issued per tank troop was not just because of the scarcity of Firefly's but also because the Fireflies were only issued with AP ammunition. Since tanks fire far more HE than AP this could be a problem if you converted the whole troop to Fireflies. The 2nd generation HE round was a big improvement and several hundred thousand were churned out in the last year of the war but it was still inferior to the 75x350 HE round.
