IMAGINE WHIRLLED PEAS

Suffice it to say that I have completed this project, and am happy with the results. I installed it first into my shop system where it made me want to build another just to use there. Then I installed it with my Decware ZOB, and Racheal amp to have some adjustment there. What might seem a compromise to some is a blessing to another. I still had just a touch of the shout left in the FRX2 driver after 100 hours of break in, so this was the intention all along for this BSC/treble circuit to be used. 'A treble circuit to correct a midrange problem?' In this case, yes,,, let me explain. First of all, my room would benefit from the BSC part of the circuit by the fact that bass is a bit shy in my listening room. The circuit compensates for about 4db of that and is subtly noticeable. This is accomplished by the Lowering of the Midrange band above say 120hz (not sure of that number), where as the bass will sound louder relative to the midrange. To get the original volume back, you must raise the volume setting 4db to compensate. Now, the treble part of the circuit acts the same way, but at the other end of the spectrum. I set to 5khz which lowers the amplitude of the frequencies Below 5khz by 4db. For me, the end result is that the midrange is affected again by being lowered, and the treble sounds louder in comparison. What this means to my ears that the midrange that sounds honky to me has been tuned down enough that I can enjoy the music, not waiting for the next honky note to show up, making me cringe. Yamaha has used this same concept in their 'Natural Sound' series of integrated amps, where the midrange cut is variable, resulting in a different kind of 'loudness control'. Brilliant. When/if I feel that the FRX2 drivers are fully broken in to my complete liking, then it will be time to remove this filter.
