What kind of subs do you have btw? I wouldnt doubt they are better than my sub, but he is asking for one to fit in a stealthbox, putting a 12 in their is almost pointless. Getting the T-top box is a better since you can put two and get around 1cf each I believe, but the downside is the weight and cost.

Steve is a dealer for them. Of course he's going to recommend them. There's other speakers that sound good in his box too. I can think of 4 others off hand.

Personally, I'd recommend Elemental Designs. I have one (the old flat-cone style) and it rocks. it is a 12" in a custom made stealthbox with a total airspace of about .8 cubic feet without the sub installed. After the sub is installed it is more like .6 cubic feet. I am feeding it 500w RMS from an old-school Fosgate mono amp, and it slams. I have had comments from people saying that it sounds like a pair of 12"s or 15"s, and they are shocked when they see the hatch. For an explanation of T/S parameters and what they mean, see THIS.


EDIT: howierd42: Thanks for the info.

Without T/S it would be impossible to build an optimum enclosure for any speaker, I don't care what car you put it in. It is incomprehensible to me that most installers today think you can just build a box that fits and throw any speaker you want into it and expect it to perform. I am not trying to start a debate or a diatribe here but the manufacturers do give you those specs for a reason.

That's true, I've seen so many cars with really nice equipment, but using premade enclosures (i.e. Q-logic, etc.) and the subs sound like ***. Usually you can get away with a larger or smaller enclosure size (10%) on a sealed box, but a ported box has to be tuned right (port length, diameter, etc.) to sound good. One thing I really hate is Best Buy selling the premade bandpass boxes.

Thats because they usually buy a pair of 15"s from Best Buy and stick them into a Q-logic premade box.

Capitalism at work. I don't mind them selling them, if someone buys one and makes their subs sound like crap in it, it's their fault for not knowing what they're doing.
