cool thanks again

must be the way i built it, not quite sure. But thanks for your time. Is it possible to adjust the length of the port to get different box tunings.

Yes, I added filler boxes to decrease the internal box volume. thanks

Why would you use the inside dimensions for the filler boxes, I used the outside dimensions of the filler blocks for the calculation since they are taking up space(or air volume) so the outside dimensions are the critical dimensions. So the 2.4 ft^3 box ( I actually get 2.4 ft^3 this calculation...

Here is the actual internal dimensions of the main box = 12.5x18x18.25=4106.25/1728=2.38 ft^3, then I build the two smaller boxes and I glued them inside the box to occupy air space, so the outside dimensions are 10x5x5=250in^3/1728=.14 ft^3 6.75x17x5=573.8 in^3=.33ft^3 So, The main box minus...

Its 3/4" MDF, the dimensions provided are all outside dimensions. Main box 14.75 H x 19.75 W x 19.75 D Inner Box#1 = 6.75 H x 5 W x 17 D Inner Box#2 = 5 H x 5 W x 10 D I'm trying to achieve a good tight heavy metal double bass sound, and currently I feel that transient time is a little...

I'm also currently running a 4" port at 13.5" long.

Just signed up yesterday, I posted a question and I had a reply within an hour. This forum rocks, and I hope to contribute in some way.

Thanks for time.

I have an ported 2.3 cubic foot enclosure, I ran an older 12" JL 12W4-4, and this was the recommended size for a ported box design for this speaker. I recently shredded the speaker's surrounding rubber and I'm the market for a new speaker, but non of the speakers that I research require such a...
