So speakers are built, sounding great. Nice deep bass, yet not overpowering. It's real. Most speakers out there have what I call fake bass, they over emphasize it to satisfy the bass hungry US market. The horn L-pads are set on a little less than 2. Which makes them smooth and seem to play the easy going music I am into, beautifully.
I'm not sure of the sensitivity but with just 8 watts of 300b power I can get the volume maybe to 25% and that is house shaking. The jbl woofers are rated at 103db.
My dampening is not totally covering inside the cabinets. The front face has none, and the rear door has none either. Just top bottom and sides. I added some insulation in the corners so there is no sharp areas. I'm ordering a couple packs of acoustic wadding this week to try it on the back and maybe the face.
Problem is when I really crank up the volume, it is harsh and hot.
I'm going to build the 1200hz xover and test side by side with my present 800hz xover. I'm adding the dampening. Is there anything else I can do to tone this down a bit. Aside from turning down the volume
My room is small and there isn't a whole lot of room to spread them out. I think bouncing off the walls could be part of it. Should I dampen the 511 at all?
I just figured I would ask since I'm sure some of you could have gone through this before.
For the record my room is only 11 ft wide and I sit 13ft from front wall.
Inside speaker dimension is 22w x18d x29h and are 3/4" MDF and solid and heavy.
Drivers are 902-8a/511b and 15" jbl d130
N801-8a xover w/ Jantzen caps
Thanks for any thoughts
