Finished up the subs last night. Now i just need to find time to connect all the parts back together. It won't be this weekend though, I'm going out of town on a snowboarding trip. Maybe next weekend we can make some sound up there and if I'm lucky maybe watch a movie!
So that brings the subwoofage to 8 MFW-15s(Sealed) and 1 Maelstrom 21 running off 3 EP4000s. I'm looking forward to the increased output and seeing what I can get on the FR.
I'm going with a classic Toole/Harman sub layout with subs at each midpoint of each of the four walls.
Its going back wall. I might do a low pass on that one somewhere like 50-60Hz depending on how it sounds.
The two duratexed MFW cabs are going up front behind the screen, hence the forward firing woofs. I'm either gonna co-locate them in the middle or spread out to the 1/4 points of the front wall just depending on how it measures.
It should be a noticeable improvement. Two sealed dual opposed did a decent job in my room on a single 20A line. This upgrade included two extra 30A lines, two Extra EP4000s, and 4 more sealed MFWs.
Finally got all the electrical equipment hooked back up.... The theater made noise this weekend for the first time in over a year, O how I have missed it.
The room is still a mess with cables and such but hopefully I can get a pic of the equipment rack with its new glass door tonight and post up. Lots of cleaning up to do and then endless tweaking.
Adding the Minidsp to the mix produced ground loop hum, which I chased out of the sub system. It then ran and hid in the mains. After some more chasing I got the hum reduced to the point where you can barely hear it when ear up to the wave guides.
I'm still not satisfied but will probably start calibrating etc and chase that last bit of hum at a later date.
I'm going to update the minidsp in a rackmount box thread. I had to isolate the power supply and go three prong on the mini rack box. The power connector on the dc plug was not isolated from the box which caused major hum in the sub system since the balanced connectors short the shield to the case.
