My house hates me..............
Well, I couldn't wait any longer. I wired up and installed one of the Mals today and hooked it up on one channel of the EP2500 and laid it on its side (feet not on yet). I played it easy for about 15 minutes doing a quick ear tune. Then I decided I wanted to play some test tones. Started at 15Hz and then went up in 1Hz increments after that. I was playing with the level to see what kind of crying my house was going to do.
Now mind you, I am testing these out in my finished basement "bass cave" where I currently test all of the subs I build (not the final location for the subs). In the basement I have a Harman Kardon AVR510 receiver hooked to two Electrovoice ZX1 commercial speakers, a JVC dvd player, an MCM unbalanced to balanced converter, an Elemental Designs EQ.2, and an EP2500.
The house was built in 2005 and is pretty sturdy. I heard it making noises I never thought were possible. I was easing the levels up on 15-20Hz and the drop ceiling tiles in the basement bathroom were levitating! My poor laundry room shelves have emptied themselves of all of the detergent and folded clothes. The basement windows are flexing in and out and sqeaking like they want to burst.:yikes: I went upstairs and the floor was shaking so bad that if you stand flatfoot, your eyes go blurry. Needless to say the output is intense, and this is one of the two! I was able to reach the limits of the EP2500 in stereo. It clipped a few times.
The only concern I have is a slight chuffing from the port on some frequencies:scratch:. Not sure what is going on there. It is slight, and maybe I wont hear it when I eventually stand them upright. Any ideas?
I can say that I am very impressed with the output of these Mals in this configuration!:hsd:
I will keep updating as I finish the other and put it all together and EQ it.
