Vertical version would be nice......so would a horn but that would require a bigger box right?

well, a horn is a whole different thing and they tend to get pretty large when shooting for something like 17hz, but can be done. much more sensitive to the driver though.

those pre built subs are the wrong thing. their tuning frequency is almost certainly up around 30-40hz, which is great for a car, but not what you want for home theater.

the marty sub that I linked you to is tuned to around 17hz. that is along the lines of what you want for home theater.

Oh, okay. I like the Marty sub but I was curious about the boxes on ebay.


BTW, I think I blew it when I bought my 4 SI subs. I ordered them all with dual 4ohm voice coils. I originally planned on two subs per box and running the voice coils in series and then parallel the two woofers bringing the load to 4ohms per box.

If I ran a single sub per box what's the best way to wire them, 2 or 8ohm? Or am I better off just running two woofers per box? I hope I didn't back myself into a corner. I have two Berringer EP4000 amps available for the subs.

You could wire two sub's for 4ohms on one ep4000 bridged.

or you can wire each sub to 2ohms and run the two ep4000 in stereo. Each sub to a single channel.

Interesting, I did not think the amp could handle a two ohm load....that keeps all my options open...sweet!

Is there an advantage to either option? Also what is the preferred way to split the Single LF out to two amps? I see people use the mini dsp and some other equipment that I can't recall at the moment..one made by Berringer.

I run my subs in two ohm stereo, not a problem.

I believe 4ohm bridged is the same as 2ohm stereo so I'm not sure if either has a advantage power wise. The best way to split the LFE output is to use a cheap rca splitter like this
