At $360 for the pair, the Behringer Truth B2030A monitors are hard to beat. I used them for years with the AX8, FM3 and Axe III, presets translated very well live.
This is probably the best bang for the buck you can get. I use the Truth B2031A with a SVS SP-2000 Pro along with the DCX2496 DSP. I used REW and the ECM8000 measurement mic to make many, many measurements to get a very good response in my room. REW was also very helpful in figuring out where to place additional sound treatment in my space. I have 25 2'x 4' x sound panels ranging from 3-4" deep loaded with 2" Rockwool RHT80 and SoundSafe. The 3" panels use RHT80 and the 4" panels use SoundSafe.
This is my last measurement with the correction from last year. It is not supposed to be flat. I am using a target curve that has a bit of a rise in the low bass response and a slight roll off of the upper treble around 6K.
My target curve is more like this... (measurement and target curve are attached below)
The DCX2496 does the EQ and crossover for the mains and sub. Although, the SVS SB-2000 Pro has programable DSP built-in.
Anyway, the main point is that the Truth B2031A monitrs have a lot of power. And the woofer actually measures closer to 8 and3/4".
I have done a bunch of tests and my conclusion is that modest speakers + acoustic treatment (rockwool or compressed fiberglass) + a home theater sub will yield results that are far more accurate than a pair of $4000 monitors and nothing else.
Home theater subs (like SVS or Monolith) are so much better than any "studio sub". They go far lower and louder with distortion that is extremely low.
