October 1, 200519 yr A couple things...Sweet flat cones.Sweet enclosureHOLY OVER BRACED !!!!!!!!!Can i have some of that " secret glue" on my hot dog please
October 1, 200519 yr Great construction. The drivers look very nice indeed. I hope that caulk dries clear.
October 1, 200519 yr Author no it won't. I grabbed the wrong tube of caulk. I used some silicone around the subs and that is clear.
October 6, 200519 yr I like the low tuning, always a fan of that.I would like to see a negative response to this project. Very amazing.
October 6, 200519 yr Looks very good.I just thought that if those woofers were placed in a box that was lacquered to hell and back (like some monitor's are, really glossy) I would come to your home and they'd be leaving with me. That Soundstream amp looks cool, do you like it?
October 6, 200519 yr Very nice setup. That is one sexy box. Might I suggest you get some spreay paint and go over the caulk to make it not stand out so much?Still a very well built HT substage.
October 6, 200519 yr Author I'll post a negative. The paint isn't 100%. I wish I would have used body filler over the entire surface and sanded to get the best possible surface for painting. I would hace also gone with a bedliner time spray on but this is fine if you don't go right up to it under the light.I also need to put in a port brace since I can almost feel the ouside wall flexing. Soundstream Amp is nice. I also have the matching C-1 pre-amp and T-1 tuner. The amp is just starting to clip at the maximum I would want to push these. The amp does get real hot when pounding away.I've been delaying speaker porn and the output mesurements. SOON...
