Suggestions Creating Subwoofer Box(s) - 56 cuft available

2MuchRiceMakesMeSick · 16th January 2012, 09:13 PM

I have a total of 76w x 80d x 16h (56cuft) that I have available. Which seems to be a good amount of space for 4-15's in a t-line configuration or a tapped horn.

Suggestions on box configuration and or subs would be greatly appreciated. I have not bought any drivers or amplifiers yet. I will be using pro amplifiers.

I do like the bass loud but sound quality is my #1 goal.

Thanks in advance for the advice!

Hi 2MuchRiceMakesMeSick,

The 16" dimension will make a TH more difficult, you need about 2" more than the basket O.D.. You also will have to define your parameter: cost, output SPL, portability... For starters take a look at this thread:

Thanks for the reply.

Cost: Would like to keep the subs less then $750 usd each. So no more then 3k for the subs.
Output SPL: I think im using enough drivers that it will be plenty loud. Quality is my #1 goal.
Portability: Its a permanent install.

Hi,

How about a design similar to the DTS-10, but with the TC Sounds Epic 12 (for sale at Parts Express):

I may be able to squeeze a few more inches. What about two of these drivers in a tline configuration?

I am still reading on the DTS-10 box

To confirm- the available front baffle space is 76" x 16"?

Yes I can use 80x16 as the front baffle or 76x16. I was thinking about 3 18's (TC Sounds LMS Ultra 5400) as they would fit very nicely and seem to have the parameters you look for when designing a t-line.

Hi 2MuchRiceMakesMeSick,

Because of the price point I would prefer the TC Sounds Epic 12. If you're thinking in the direction of a transmission line: since the advent of Hornresp and AkAbak I would not recommend the simple TL format any more (OK go ahead just shoot me :-)), but I would go with bjorno's favorite the T-TQWT instead. Two of the 12s in a T-TQWT would be as loud as one of the 18s for a given power within the 12s Xmax limitation, and with two drivers you can reverse mount one to provide you with additional distortion cancellation.

I'll attach a quick price v. displacement comparison:

Hi again,

I took a real rough run at it, and four T-TQWT boxes, each with two TC Sounds Epic 12", would fit into that space just nicely. They would be single fold, quite easy to build. 76" x 16" front face for the four.

Regards,

2MuchRiceMakesMeSick · 17th January 2012, 03:00 PM

Ok I will look into tapped horns.

Is there any way, if I increase the height to 18, that I can fit two TC Sounds LMS Ultra 5400 18" in that space in a TH configuration? The reviews I have read on this subwoofer are VERY impressive.
