Hello dear Hometheatershack community,
after a weekend of reading and tweaking and going back and forth I think I am finally ready to post my first graphs. Subs are two Klipsch KW-120 powered by a Klipsch KA-1000 THX Amp. The crossover is set to 80Hz at my Yamaha 3800 which serves as a preamp for my 5 Marantz Monoamps powering 2 Klipsch CF-3, 1 Klipsch KLF C7 (center) and two KG 4.5 (rear).
I seem to get a nasty rise above 20Hz which makes the house shake and my girlfriend comming up to my theater room :foottap:. The response is shown in the first graph, subwoofer runs a little bit hot me thinks. I tried the Boundary Room Gain Correction switch on the KA-1000THX which brings down the peaks and allows me to run the other low frequencies louder as shown in the second graph. Both graph are recorded with the same settings and volume levels, subs only. Only the Boundary Gain switch was off in the first graph. I think I need a FBQ to tame my lower end right? I was initially planning on an Anti-mode but seeing that I can get a FBQ 2496 for less than 140€ here in Germany I am rethinking my decision. I also like working with REW. Just have to find out how to safely connect the FBQ between the Yammy and the KA1000. :nerd:
Graph 1 no Room Gain correction 2 Klipsch KW-120 XO 80Hz
Graph 2 Boundary Room Gain activated 2 Klipsch KW-120 XO 80Hz
I am really looking forward to hearing from you :R
