I think it is safe to say that something called 'Kaboom' is not designed for high quality.

Surely there have been some objective tests that have proved the efficacy of the BBE system?

The most objective test you are likely to find will be BYRTT's above. The loudness feature might be useful, but there are simpler and better ways of doing it

On the contrary, it assumes a lot of ignorance and is written to impress such people. It does not appear to be technobabble; it is technobabble. The only question is whether the author actually believes it himself; is he foolish or dishonest?

For example... i started off with the effect impedance has on current flow.
I am pleased to hear that you have some understanding of impedance.

Quote:
I satisfied myself its plausible by looking again at the impedance of a speaker and what impedance does to current flow.
I spoke too soon. You don't understand impedance.

Quote:
At its heart though I think the idea that the idea of a loudspeaker delivering sounds that are delayed by different amounts according to their frequency has plausibility...would you agree ?
Only if the radiating 'centre' of the speaker is displaced. If so, this would normally be corrected to some extent in the crossover network; it certainly cannot be corrected generically by some external effects box. Therefore their claim lacks plausibility; in fact it is worse than that, it possesses a ring of untruth.

Quote:
It is the impedance of the speaker that varies with frequency. .. can you follow the implications of that wrt delay of electrocal signal at the voice coil.
We can. We suspect you cannot.

Please stop putting stereo and Dolby in the same sentence as BBE. You are merely exhibiting ignorance, which by now is beginning to look like wilful ignorance. If you want to learn then this thread has patiently given you lots of useful information, but I fear that you may prefer to stay as you are.

What you can say... is that the descriptions are all very positive. Whether they are high fidelity or not cannot be conveyed very well in words now can it.
Those description might seem positive to someone who is not interested in high quality sound reproduction, but prefers to be impressed and impress his friends. That is, the typical consumer of modern audio.

All three of these are at their heart trying to achieve a more realistic sound arent they. Can we agree on that.

Dolby and BBE are both aiming to compensate for inadequacies in the record and playback systems..this much is true in concept.

Now..Dolby isn't perfect. Neither is BBE but both have the same aim in mind. Whether you agree that they acieve that aim is up to you.

I understand that for some reason its not popular here but if we are interested in true HiFi then why are flawed systems like dolby which arbitrarily lifts 'certain' frequencies on record mode accepted, yet BBE which also picks certain parameters to work with is not accepted.

In fact each is flawed (imperfect). So why accept the flaws in one and not the other.

You really should quit now. You'll hit bedrock if you keep digging!

It is clear that armarra1 is not listening. I therefore see no point in repeating myself.

Compensate for inadequacies Dolby is a Noise Reduction feature that if turned on under recording process to tape will encode its filter pattern and when replayed needs the inverse decode turned on else sound is not right, this is totally different than BBE because industry of the world have adopted Dolby as a standard because it proved its worth, its precise because encode pattern is known then decode is simply the inverse and also in its hardware is some integrated circuits stamped with a Dolby laboratory logo its possible get device within good specs and drift.

BBE is not adopted in industry as a standard and its decode is not a reverse mirror of a known error, BBE is at its best shooting for a "kind of mirror curve" and therefor we are some that call it effects process, can't know exactly if it acts like the simulation in post 207 but if it does i call it a sommerhat and business more than a serious filter to improve waveshape.
