Your options would be SDX12's in 16" diameter sonotubes

SI HT 15D4's in 24" cubes as they won't work in a sonotube.
How do they model in a 24" box?

Re: Need help planning a DIY sub build

So here I guess are my driver options:

1. CSS SDX12 (duals): $519

2. Dayton Audio RSS460HO-4 18" Reference HO Subwoofer 4 ohm (duals): $500

3. Stereo Integrity HT 15D4 (currently unavailable): $Unknown

4. Dayton Audio UM15-22 15" Ultimax DVC Subwoofer 2 ohms Per Coil (duals): $400

5. Infinity subs (I just cant see these things performing well given their cost)

Then the obvious is ported or sealed. I prefer ported but guess Sonotubes are out as I dont think the height needed will work to my advantage. I am not against sealed its just normally they dont give you the needed numbers down low v. ported. I may go with a sealed box or two later on closer to the LP just to reinforce things, but starting with 2 for now.

So I am wondering how any of these will model in a 2 x 2 x 2 box (measurements include ports & bracing). I am relying on a buddy to make the boxes for me on this as I lack the skills. A box smaller than 2 x 2 x 2 is fine too if its possible.

I also VERY MUCH prefer to go with 2 subs rather than build one sub dual opposed. I am looking for more even bass response which is achieved by using more subs spread throughout.

Thoughts are still VERY MUCH appreciated as I am running around in circles in my head it seems.

Total budget right now is ~ 800 for drivers & amp. Under would be fine as it leaves money for parts....

Re: Need help planning a DIY sub build

The best value will be the SI HT15D4, they are available. They can be wired together for a 4 ohm load. They model the same as the 460HO in a 24" slot ported cube and are cheaper. Power would be a iNuke 3000DSP with a fan modification.

I didnt know that model was available. So are you suggesting a total of 2 of those subs each in its own box with a iNuke 3000 or are you suggesting 2 sets of dual opposed of those in a 24" cube?

It's not their cost; it's their value (cost/benefit) when used appropriately.

More expensive drivers can be used, but unless you have the power and enclosure volume to take advantage of their potential, then you are spending more money for what?

As far as them performing well, all you need to do is search on here or AVS. They work great in the right application for me; see what others have to say about their builds for yourself.

One in each cabinet ported, both powered by the iNuke.
