What a great project. What did this cost you (time and money wise) soup to nuts? I am considering my first DIY.

I got the dual 4 ohm version. I thought I would then have more flexibility that way. I can run it series for an 8 ohm load and 550 watts (the way I have it now), or in parallel for a 2 ohm load for 1250 watts. These are the RMS specs directly out the manual of the EP4000. The only thing I cant do is 4 ohm mode for 950w. Keep in mind Im really bad at math and have little to no real understanding of electrical stuff. My logic is also suspect at times.

I have to say that I didnt expect a woofer this size to be so musical. I mainly bought it for realistic LFE in movies. But I been running a big variety of music through it and am surprised how deep it is, yet tight and controlled.
Good to hear. I had a customer call the other day and order a couple 18" D4's and he asked me "this woofer is a good sounding subwoofer, right?" to which I replied "Oh yeah, it has [insert a few quick tech specs] but it just so happens to be able to get really loud too."

I fired it up for a brief test with U-571. Man, this thing is insane. Im using one channel of a Beringer EP 4000, and I will definitely have to to go around the house and fix all of the things that are rattling now.
You might want to try a Gramma first. I had a bunch of things rattling from the low frequency too, and that cured just about all of them. Or, since you seem very good with your hands, perhaps you could build an equivalent for half the price.

What a finish! I think the US Geological Survey is picking you up as about a 3.0 earthquake.

Re: Single SI HT 18 build

I couldn't find which driver you got. Is it the dual 4 ohm or 2 ohm? I'm assuming dual 2 ohm. I think that would give you around 600 watts on one channel of that amp. You should be safe in that size enclosure.

Way too nice to stuff into a corner! But if that's the best spot, that's the best spot.
