Box for 2 10's

[Bob Tzimenatos]

In need of a little assistance. I am having some trouble with the free online box calcs. I want to build a ported box for two Pioneer TSW261D4's. 10" . They currently reside in a ported box I got a few years ago in a CL deal. The subs are new. Running them off a PioneerGMD8601 @1 ohm. The box they are in is 1.1 cf per side, port is 10.75" x 2.75" x 10.25" long.

While it sounds ok, i know I can get more out of this sub/amp combo. If JoeX or someone could run these numbers for me, I'd be grateful.

Sub specs

Pioneer TSW261D4

Dual 4 ohm, 10"

Qts 1.04

Qms 15.49

Qes 1.12

Fs 46hz

Vas .63cf

Vd .0125 cf

I like my lows- Psyph, Decaf, etc.

System currently resides in my '04 TrailBlazer, but will end up in my daughter's '06 Charger when I go big.

I'm an Old School SQ guy from back in the early 90's. LikeI said, this is just a pacifier system until I go big- 2 15's on 4000+w

I tried a couple online calcs and came up with strange results. One said I needed 14.something cubes.

It's going in a Trailblazer, max dims available are 46w x 15h x 20d

just wondering on the configuration of the box you have now... shared chamber single port, shared chamber dual port, 2 chambers 2 ports.... because I am coming up with a 50hz tune if its a shared chamber single port all other configurations have even higher tunes....

something like this might be able to transfer later on to the trunk of a charger

It's single chamber, port between the subs. Thanks for the design, I like the tuning much better. Gonna build it and test. Since I still have the prefab box, I will be able to compare the two. Thanks again.
