Any pics of the TC's? Love them all.

Build the box as big at it needs to be to fit the third passive, or a fourth if you can, then add blocks of wood inside to reduce volume to what's recommended.

Is this internal volume, and does it include bracing and displacement? For example, could I order a 5 cubic foot box tuned to 28hz, after displacements? Always loved watching your builds, can't wait to see more

I heard he makes some good enclosures. His name is Pete Kulicki

200w difference isn't audible, not to mention those amps will do more than rated anyway.

Glad you got it fixed Are you sticking with the smaller port? Also, polyfill doesn't work the same as it would in a sealed enclosure as in a ported box; I'm not really technically knowledgeable but there are a few threads on the board that could explain why

I reallllllly want to find an A3000Gti for when I get a Trident. Might even crumble and get a 2200.1 for the btl. Seen a few for sale on Facebook.

JBL BPX 2200.1 if you can find one, 2k+ @ 4ohms. Class A/B

DSS Ethos 15"

I've had my fair share of troubles from substance abuse, maybe some of you could take something away from reading this. I did. http://m.huffpost.com/us/entry/6506936

I would say port and woofer on a common face is best for trunk cars.

Depends on the note in question

I have a Fi BTL 18d2, fully loaded. Low punches, or kicks can sound empty like that below tuning . I think it's something to do with not enough holdind it back at the end of its stroke so it weakens the sound if that makes sense. I've found that I prefer a much lower tuning, and a strong midbass setup to make up for the woofer's lack of dexterity in that region. You've come to the right place to learn some stuff =)

That last note is pretty low, I'd say thats the woofer getting beat up below tuning. Hence the weaker sound. I'm tuned several hz lower than you and I'm still reaching a bit for that note. If the higher tuning is what sounds and feels better, what I think the next step is is evaluating the box itself, placement and port placement; maybe more surface area could bring you what you're after.

2.5way?

Welcome to SSA 38hz is actually a pretty high tuning. When does your woofer makes that hollow sound?

They'd struggle to perform properly in too small of an enclosure.

I mean, in a good way

Had a AQ2200.1 on a pair of Type R's a few years ago, it was a solid performer. Would be happy to own another. However, the Hifonics wins my vote for equivalent performance, and being half the price lol

The trunk adds a pseudo bandpass effect, likely boosting what feels quieter now. What's your box tuned to?

It's a different kind of sound than the boom you're used to firing off the trunk. In my friends cougar it didn't feel as loud, but it sounded much cleaner and this was only with a pair of kicker comp 12's sealed in 4 cubes on 300w.

Hifonics brx2000 served my brother and I well. Not very expensive either.

What about working on your front stage and electrical before adding the sub? Front stage can be a mission in and of itself. And you don't need a four inch coil to get mean =)

Single eighteen is double the area without needing double the power. That'll help dig low

very nice.
