Hey guys one last thing. I had the w7 with a 2.5 cubic foot box that we agreed was probably a little too big.

I recently traded the 12w7 for a 13w7 and was wondering if the 2.5 cubic foot box is good for that? JL recomends around 2.35 Cubic feet but i always hear manufactures specs don't sound great.


Long story short is a 13w7 good in a 2.5 cubic foot box tuned to 30hz?

you can always reduce the box volume down to the 2.3 to 2.4 cu ft range by adding sand or MDF to the bottom of the box if you want to alter volume till you hit a sweet spot
Just remember you're also altering the tuned frequency by doing so

another thing to remember is the actual sub displacement itself. not from the 12w7 to the 13w7 im not so certain how much then differ in actual displacement but your box size will be smaller by switching out the subs alone.

Ya after sub and port displacement its 2,5. I'm just wondering of that is too small for a 13w7?

Ok so i decided im starting from scratch and building a new box for the 13w7

- What volume (after port and sub displacement) would you guys recomend for a 13w7?

- And what tuning would you recomend for a 13w7?

I want to really hit the lows but not sacrifice too much output.

You dont think 2.3 is too small?

I was working with a few designes and possibly came up with 3 cubes @ 31hz. Would that be good or too big possibly free airing it?

No, 2.3 wouldn't be too small. I would have it anywhere from 2.25-2.5 cubes and you will be fine. Let me know if you want a detailed design and cut-list. I can come up with it pretty quickly

Thanks for the help and ive actually been designing a few different ones. haha.

So which would you prefer Bassman? 3 cubic feet or 2.5 cubic feet both tuned to 31hz for the best blend of SPL and SQ?

So i will be building the box this weekend and would really like to know if 2.5fft^3 or 3ft^3 would provide the best blend of SPL and SQ and if a good frequency is 31hz?

It will be recieving 1000 rms
Thanks so much!

2.5 i wouldnt go any bigger. and that 2.5 is accounting for port and sub disp.

So just to be sure you think 2,5 after subtracting sun displacement and port volume?

And how does 32hz sound for that size?
