I've been following many of the threads about DIY sub and thought what the heck: I designed and built a 800L raw 94" x 29" x 21" sub with 2 15" TC2000 SVC speakers tuned to ~15Hz with a 10" port 27.5" long. I would like to thank all on this the forum for the knowlegde to build this beast. I will be using a SMS-1 and a Behringer EP2500 to control and power this thing.
I previously used a Kef PSW4000 and have a few pictures (from the SMS-1) of the tuned response from that, I did a quick set up of the LLT sub (still not in place yet) and tested the the response of this (forgot to take pics will this weekend) all I can say is wow. Within minutes I had the new sub flat to 15Hz (this is as far as the scale goes) this was a far cry from the Kef that I had to boost to get 25Hz. I will have to attach this to my walls more securely now.
I'll post some more impression this weekend when I get a chance to place then play with my new toy. FYI I built this near the location that it will finally rest because it weighs around 350lbs. Here are a few pictures:
Yes that is the KEF sub (quite a size difference) under my center speaker not the best placement but with wall treatments and the SMS-1 I obtained good results.
Thanks to everyone again and if you are on the fence about building a DIY sub just ask a few question do some planning then build it.
