No, You Cannot Bi-Amp

So folks who use monitors with powered subs are idiot children? Its the exact same thing as those who say choose to power woofers with a beefy SS amp and power top end with warmer tube sound (for example).

Bombaywalla, I agree with your take (I think). It's not so much about the theoretical considerations as it is the execution. Maggies have perpetually been subjected (with good reason) to modifications of their crossovers. Peter Gunn made a pretty nice business out of his crossover mods. Others have gone to the trouble to use external active crossovers, and swear that takes the Maggies to a whole new level. If the new crossovers are better than the old stock ones, it is likely due to better parts and better execution, rather than the inherent advantages of the series design. All I know is, the stock 3.7's sound a whole lot better to my ears than the stock 3.6's, which leads me to hope for a similar improvement in the 20.7's over the 20.1's. But the advice remains, go listen, let your ears be your guide.

Regardless,
It's not worth to rant especially the post that starts with

In my mind

Re Elizabeth's statement: Bombaywalla, I know that you have considerable technical expertise and relevant experience, but upon careful reading I don't see anything unreasonable or technically implausible about Elizabeth's statement. In its essence, at least, which as I read it is:

A few folks are able, with effort to make it work for themselves. In general it is a waste of time, if as much effort was made to have one amp work well. The worst side of it is all the folks who know nothing about it wanting to do it as if it is some easy magic panacea.

I have seen (and answered) more than a few posts here that would justify the last sentence of that statement. (In saying so, I am not implying that the OP in this thread is one of them).

Hi Al,
Like-wise, you yourself have a lot of technical expertise & your many answers to forum posts written in a congenial manner have been appreciated by me & many others as well.

Where I was coming from was:
* Elizabeth's post, to me, definitely seems like a rant (look at the way it starts off) & it seems to show that she has some grudge against this technique for reasons best known to her.
* she goes on to say that it's not "cool" to biamp but does not say why. In my mind that's where the technical implausibility comes in by omitting the technical reasons for not doing it. Thus, the forum only knows that it's not "cool" but is no better in knowing why not. Since this topic has been brought up by the OP why not discuss the merits & de-merits so that all visiting members can walk away educated. Aren't we in this audio forum to learn & share the knowledge? I don't think we are here to make blanket statements & walk away leaving everyone wondering...
Anyway, that was my angle FWIW. Best Regards.
