I have the 4412's, not the 4412A's. I didn't feel that their bass output sounded flabby, just a bit overpowering in the overall balance.
I have done quite a bit of front-of-house mixing on styles of music that needs to be reproduced cleanly, including Jazz, Bluegrass, Old-Time, and Swing.
I did not encounter a situation where a case of low end flab or blop wasn't correctable by simply raising the system's lower -3 dB point up to where the bass signal was was not asking too much of the bass transducers.
While this is easily accomplished when using a mixing console with sophisticated EQ controls, when in a home setting not so much. Actually, neither is it very difficult .
Since the adjustment need not be adjustable in a home setting versus using a system in different venues with varying acoustics, the solution can be implemented simply and need only be done once.
To clean up the bottom of my home system with the 4412's and their interaction with the acoustic environment, I raised the lower -3 dB point by placing an additional capacitor in series with the existing input cap on my Yamaha M-4 power amplifier, empirically experimenting with values until the bass was cleaner sounding and still provided sufficient low end extension. I did not use any test equipment this time, but tuning by ear was sufficient to achieve a quite noticeable improvement. So I must have had some flab, blop and a bit of tub after all.
The bottom line, no pun intended
, is that it worked and would most likely work for you as well. Regards, -D_E-
