If I recall right, Ash has played with a few T/B's and found them to be a very nice SQL speaker/sub when used according to speaker maker recommendations.
This is an odd size though. Do you have a link to this speaker with app notes? Is it full range or a woofer? (Looks like a woofer to me)

yea i found it on partsexpress....it is a subwoofer.....im just wondering how maybe 4-6 of them would sound ported. Im tryin to spice up my buick so i will want to drive it more....it sees maybe 5 miles every 2 weeks.....no music in it at all right now....and since i dont drive it that much i was thinking of going stupid loud with mulitple woofs. kinda like an spl machine but not..

Interesting... but one thing we need to know is what sort of enclosure requirements are needed for these subs??? If they need a 2 cf box per sub in sealed applications, there are better ways to go.
Also, the cost for 4 of these VS power handling indicates a moderately low power handling sub that has a pretty limited deep low capabilty, (SPL) below 40 Hz. This speaker seems well suited to upper bass and midbass applications though. (60-300 Hz. range) In a car, the transfer function will help, but if you need a large enclosure for them, is that the best route? (Perhaps not)
If porting, power handling may be degraded below about 50 Hz. Here again, enclosure size is a concern as is the EBP. EBP here is 87 and suitable for sealed or ported.
OK, before pressing into this one deeper, let's find out the recommended sealed and ported enclosure space needed per sub. The specs say Vas is 89.4 Liters. (3.15 cf/sub)
Just ran some numbers for ported enclosures. Here are the details:
Fb = 37.8 Hz.
F3 = 43.6 Hz. (-3db down point is good)
Vb = 1.06 cf (This is good as well)
Port = 2.5" x 6.66" long/chamber (This is reasonable too)
In all, not too bad in a ported box of reasonable dimensions. This is similar to what we see in a moderate cost 10" round sub with greater power hanling and probably a lot cheaper too.
In short form, not a bad woofer performace wise when using an array of 4 wired series/parallel and 4 ohms net load. However, 360 Wrms is pretty low power for the price of these subs.
Do you really want to spend $300.00 for 4 of these subs and only get slightly above average resuts?

yea i was lookin at that too.....may go with 3 12's of some type....i figure i can spend less than $100 on each sub and have massive beat..theres an array of subs out there that would work for what i want to do within that price range. believe it or not pyle makes a sub that is pretty impressive. ive witnessed it, the square series. at 35 bucks each i may run 4 10's or something. i mean ive seen these things take an avionixx 900.1 at high volume and sing like champs. ive already ordered 2 autotek ss750.1 amps. so now im just lookin for subs.

Yep, that's the big picture alright. Nice amps you ordered already for your bass engine. Now, you just need to match subs for them and build off of that.

Know what ya mean about making good choices when there are so many options out there. It can be madning or agonizing to certain types of personalities.
Something we learned in making business decisions years back, make a Pros/Cons list. It's a simple analysis tool that often narrows the options down to just a few "best choices". This helps a lot as it makes one focus on a few very specific parameters, (Features, performance, looks, specs, reliability, price and integration with other gear on hand)
Once we compare and weed out the long list, then one can focus on a short list and make a well informed choice. I use this process all the time on key purchase items too. It takes a little extra time, but it saves time and $$ in the long run. In most cases, we wind up with great choices and few regrets. This works for any major decisions we have to sort out in life. (Ie: Buying a car, house, gadgets, tools and even financial choices)
