The BBE Process--"What it Is"

Loudspeakers have difficulty working with the electronic signals supplied by an amplifier. These difficulties cause such major phase and amplitude distortion that the sound reproduced by the speaker differs significantly from the sound produced by the original source.
In the past, these problems proved unsolvable and were thus relegated to a position of secondary importance in audio system design. However, phase and amplitude integrity is essential to accurate sound reproduction. Research shows that the information which the listener translates into the recognizable characteristics of a live performance are intimately tied into complex time and amplitude relationships between the fundamental and harmonic components of a given musical note or sound. These relationships define a sound's "sound".
When these complex relationships pass through a speaker, the proper order is lost. The higher frequencies are delayed. A lower frequency may reach the listener's ear first or perhaps simultaneously with that of a higher frequency. In some cases, the fundamental components may be so time-shifted that they reach the listener's ear ahead of some or all of the harmonic components.
This change in the phase and amplitude relationship on the harmonic and fundamental frequencies is technically called "envelope distortion." The listener perceives this loss of sound integrity in the reproduced sound as "muddy" and "smeared." In the extreme, it can become difficult to tell the difference between musical instruments, for example, an oboe and a clarinet.
BBE Sound, Inc. conducted extensive studies of numerous speaker systems over a ten year period. With this knowledge, it became possible to identify the characteristics of an ideal speaker and to distill the corrections necessary to return the fundamental and harmonic frequency structures to their correct order. While there are differences among various speaker designs in the magnitude of their correction, the overall pattern of correction needed is remarkably consistent.
The BBE Process is so unique that 42 patents have been awarded by the U.S. Patent Office.

Honestly, I'm not thrilled with it. :-/

I bought one of these about 6 months ago after reading many glowing reviews and had high expectations. Unfortunately, it didn't really deliver what I want. The sound I like is the tube "grind", where the low end is big and present, yet with a good midrange growl and smooth highs. That slightly overdriven sound - not outright distorted but not totally clean either. The Good: It's built really well, solid, and high quality. The Bad: Everything seems a bit off. The controls aren't linear - the first two marks on the bass and treble make all the difference, the rest very little. Volume is like that too. The mid control is 'cut' only? That sucks - what if you need MORE mid? The parametric would seem like the answer, but it lacks a Q control and it always seems like I can get two things from it: "Too much" and "not enough" - the sweet spot is elusive. The "too much/not enough" dilemma goes with the compressor too - it seems to me the preset ratio is way too high. As for the sound I'm looking for, it just isn't there. It's way too clean and difficult to get any useful overdrive - if you overdrive it, it goes nasty/farty, not sweet. So in conclusion, if you want high build quality and a very clean, fat albeit scooped sound, this is for you. It's a nice unit, but IMHO lacks the versatility to be my cup o tea.


Great value

By DRB-7bH2A

from Long Island, NY

Great value for the money. Sonic maximizer works well, enhances bottom end very nice. Compresser is ok, however a little limited in function (only one control knob). Para mids are a nice touch, seperate frequency knob & gain control. Bright switch really boost highs well. Build quality is better than average. Overall I think you would be hard-pressed to find a pre-amp at this price with this many features.

Excellent Preamp


from Atlanta, GA

Awesome piece of gear. It's got a tube, a powerful EQ (make sure you read the manual), a smooth optical Compressor, and the BBE Sonic Maximizer. What more can you ask for? Can be very warm or slightly hi-fi in tone, depending on your EQ settings. Definitely more warm than my previous solid-state gear. If you're looking for distortion, look elsewhere. This is natural, clean, warm it should be heard. Leave distortion for the guitars.


Small cost, Big payoff

By ambidextrous.tones

from Louisville, KY

I purchased mine used from an auction website. It joined my low-budget rig consisting of a Cort Curbow 5 Bass, Behringer Ultrabass 4500HD, SWR 2x10 cab, and a Behringer 1x15. I actually never did mind the overall sound I was getting; it wasn't necessarily ideal, but it did get heard in a very loud band situation. I stumbled onto this unit in researching the BBE Sonic Maximizer, something I thought would help define my sound. This unit offers what I desired and more. The overall sound is so much warmier with the tube, the eq, despite being boost-only on treb and bass, cut-only in mids, is very versatile, and the sonic maximizer does an incredible job of pulling the frequencies together (something of which I was skeptical until I finally heard it). The comp is limited, however, very effective, and the para mids offer alot of flexibility. For me, this unit is perfect. My tone is transformed into something much more pleasing and professional, and I didn't have to dump thousands into a new rig.


sweet tones

By Nick2

from shelton CT

i was able to dial up a sound so quickly. the para mids help you sonically weave right through the mix to be supportive to the guitars yet heard very distinctively. The lows seem to never end. and the highs are crisp. the compressor has a simple one knob adjustment and the maximizer is just icing on the pastry. so far, I am very happy with the preamp, hoping it will stand the test of time on the road!


Excellent tool for great sounding

By Oscar-XDco_

from Bucharest, Romania

I bought one a few months ago, I heavily used it since and I'm very satisfied: lot of headroom, a rich and powerful tone, perfect for bass player looking for a killer sound. Go for it!I'm using it together with my MM's (Ray5 and Bongo) and it's all that I need for live performance.
