I was thinkin about this thread for a while, and I think if we get the right people in here to talk facts, we can cut down on a ton of "what subs to choose" threads. If this takes off well enough, maybe even a sticky
So when we look at a subwoofer, we normally just ask what kind of wattage it can handle and what size we need. To some people who are new to the game, the bigger they can buy, the better. Unfortunately, I think I kinda did this when I bought my first subs. But let's take a look at what really makes a good woofer, shall we? This is not the Bassik knows all thread, hardly, I'm looking for information here as well, so lets try and through out as much as possible!
1) I guess that when we look at a woofer, the first thing that can pop out to us is the motor. A ton of woofers I have seen today seem to have the same kind of setup. The triple stack ferrite magnets. There have been some "advancements" though that we can look at. The first company I kinda think of is going to be Fi/AA. When they came out with the new BTL last year, they used a much wider, single slug motor. Are there any real advancements to this? If so, why? What about that motor makes it more powerful? Next from them, the SMD. This might start some fights, but I think if we can get the information out, it'll be worth it. It looks (to me) like it's just two of the normal 3 slug motors bolted together. Does this hold promise? Another company I noticed that is upping the ante. T3 and TC. They have these massive 4 slug motors, does a bigger motor mean more power, or does this just have the looks that people want. Discuss!
2) The second this that at least I notice when I look at a woofer, is going to be the basket. The most commonly used on I would think if the 12 spoke basket. Why is this basket so common? Is there anything that makes it special, because when I see something that is so commonly used like that, I can't help but ask, is it just cheap or something? The next basket I wanna talk about that giant 4 spoke basket on the new T3 woofers, some TC I believe, and the SMD. I heard from "a little bird who might happen to know a ton about this" that when compared to the 4 spoke, the 12 spoke vibrates and can reduce SPL. Can this be true? What about stuff like, say the TFR baskets, just those straight beams. What about the DD ones? Why does everyone kinda have a different basket, does this mean it doesn't really matter? Have at it!
3) Thirdly, I want to take a look at the coils. What makes the whole subwoofer thing work. What makes one unique? What about the ARGS! I don't know anything about coils, so lets have some builders fill everyone in on coils! Length, layers, flatwound or roundwound, and materials? GO!
4) Lastly, we will end this all up with *the rest of the woofer* I have seen big high roll surrounds (AA and many many more) and then some like CD's taller thinner surround. What does this have to do what how the woofer plays, or is it just cosmetic appearance. The cone, does harder or softer make a difference in how it plays? More weight for the coils to move? Spiders, I have no idea...talk. And lastly, the leads. I have seen ones like AA's the many thin "ribbons" and work, or some like the thick "ropes" that lace through the spiders to the coil. Do these affect anything or is it just personal preference. umm...fight?
If this thread flops, I can say that I tried, but I hope it doesn't. This information may be scattered all over the site, but I wanna put it all in one place, so instead of people making more threads, we can refer them to here and let them learn so they can make their own educated decisions.
When posting, please put in what your going to discuss, like in parenthesis or something, before you go on your information spree. This will help people find what they are looking for. Mods, I want this thread to be a place of solid info, like the WebMD of woofer decisions, so if we have people disagreeing with no relevance to the information, clean it up. I'm hoping this works, lets see what happens!
