RE: Why bi-amp Mags?

Steve, Satie just covered some of the bases very well. Emailtim also added useful links. Many of us who have navigated those waters enjoy music delights few folks can get at any price remotely resembling the price-to-value that can be obtained. Granted, it is often a DIY-driven effort. One which requires not so much money as dedication and some skills. But if I did it...

So, not that this is for everyone, but "expensive" it does not need be. In fact it can be EXTREMELY cost effective. And, in terms of customizing to your own needs, priceless.

In a few minutes my gear will be warm enough for a serious listen -- of some recent tweaks I now need to refine :). Still, my set of very cheap old MMG's are already shaking my seat here, 30+ft away. That's plain MMG's with no woofers or subs, mind you. Their bass is not just extended and strong...delicious instrumental textures are also retained. Their tweeters are delivering a cleanly extended, ribbon-like quality at the top end.

The music can be listened on for tens of continuous hours, in a 3D imaged -- often larger-than-room -- sound stage. And, if I were sitting in front of them, even "out-of-tune" as they still are, their dynamic slam would belie their being planar speakers...and laugh madly at being called MMG-like.

That's with no preamp at all, straight out of cheap class-A DAC, into a simple passive crossover network and into the power amps. Then, each tweeter and mid/bass panel gets its own dedicated juice, about 300w each. My cheapies I would not trade for many speakers at any price point.

In my case, purchased along time, the decent power amps were less that $700 in total. Furthermore, I only paid about $100 for the Teflon caps I now use in the PLLXO filter set. These are not mandatory, at all. In fact, initially, $30 bucks in good parts provided a superb duo of 1st/1st and a 1st/2nd order sloped two-way crossovers.

If you need more, passive filtering may not be enough. Luckily, active systems can be sweet too! And with the cheap super PC's and mini boards now available, there is a world of crossover filtering flexibility to provide all kinds of DSP goodies, for those who want it. No need to break the bank, just some smart purchasing, patience and proper advice, if needed.

On the later, for those with the serious interest, some decent folks here will provide guidance. This really comes in handy if you have, or plan to get, planars, more so if Maggies.

Darn, I may sound a little bit of an evangelist... Time for the music.
