Am I wasting money on the theory of Bi-amping?

Probably been mentioned, I didn’t read, too many replies.

Bi-amping with matching amps is of no audible value.

You could Bi-Wire (if that is what the speakers are designed for), that is a different concept: use 1 cable construction for mids and highs; use different cable construction for lows.

Bi-amp is to use what you think is a better sounding amp for mids and highs, needing less power than bass. And use a different amp, perhaps less delicate, but more powerful for the power hungry bass.

You could even mix tubes for the mids and highs and a SS brute for the woofers. Think of self-powered sub-woofers, they typically use SS brutes, perhaps class D to avoid heat while delivering substantial power, while the primary speakers are driven by a ’better’ amp, often tubes.

@lonemoutain, I think we are seeing the same thing from a different angle. The OP seeemed to suggest that he was considering biamping his speakers that have passive cross-overs already included, not active loudspeakers, as that would probably be moot.

 Acitve loudspeakers have existed for some time now, though they seem to be more prevalent in the pro sound market than in the home audiophile market. Though there has been more recent growth in available active speakers geared towards the home market, What you have stated regarding active speakers and true DIY projects are certainly true. But I think that for the home market, speakers with passive crossovers have traditionally domiinated the market place.

Passive speakers can be designed with equaization and/or with compensation for driver irregularities, impedance smoothing, containment rolloff, time and phase corrections with traditional passive parts. I'm not suggesting that this built in compensation is typically user adjustable. Most traditional off the shelf active crossovers only give a number frequency bands for drivers and slope options. Newer digital crossovers offer much more customization.

@elliottbnewcombjr , I had the courtsey of reading the other posts, including yours before jumping in with mine.

Experience has led many away from mixing amplifiers as the passive crossovers will still allow bleed from the amplifers into the other side of the crossover region. The effect of which will vary with the slope of the crossovers used. I think most have concluded that using identical amps advantageous. Most of the modern active loudspeakers are not using tubes in the mix.

Though biwiring typically shouldn't be confused with biamping, mixing cables might have similar effects.

Erratum :  …”containment rolloff,…” would be most typically done with equalization rather than the suggested …”with passive parts.”… 

unsound

my words were dumb, I had 3 dr appts, wife was waiting, usually I have too much time, read all responses to learn stuff. This time, I wanted to send a quickie idea.

I don't understand the crossover stuff, however, MANY add self-powered sub-woofers to their existing systems. Existing system might be tubes, self-powered sub probably class D, that was what I was thinking about.
