In Reply to: BBE - Is there anyone who does not need it? posted by John Kercheval on March 14, 2007 at 13:38:40:
We already have way too much studio processing in this digital audio world!If there are serious frequency response errors in your room from standing waves, or from placing small speakers far from all walls, some frequency response processing can be very audible and very helpful:
A digital five or more band parametric EQ dedicated to a subwoofer may be the best investment audiophiles with subwoofers will ever make.
If audiophiles use small speakers that are supposed to be placed near the front wall, but want to place them far away from all walls for a holographic image, then a special passive circuit, or a 30 band EQ, can be used for baffle step diffraction compensation (fancy words for the speakers will have too much output over 500-1000 Hz. if placed far from walls).
No other processing is needed beyond those two uses of signal processors, IMHO ... and buying a 30-band EQ is a gamble because it can so easily make the sound worse.
- Parametric EQ for subs has no disadvantages other than not being needed in about 10% of rooms (mainly very large rooms)- Using an equalizer for minor frequency response cuts required for baffle step compensation trades off better imaging for a slight amount of noise.
In my opinion the BBE is nothing more than a treble booster ... and boosting treble is the last thing we need to do for CDs -- we need to reduce treble output for most CDs played through most speakers because we already get too much treble/detail on most CDs versus live acoustic music (unless one sits in the front row all the time).
Does the BBE make speech more intelligible?
Yes.
It could be very useful for low fidelity systems with insufficient treble output.Of course that's my opinion based on only one audition where the speakers were Paradigm 100's, which were already too bright IMHO, before the BBE was used!
