Anybody have an actively multi-amplified system?

active sub-division before amps is the right way.

Amazing.
3 OP with the exact same question.

Yes Dfhaleycko...the crossovers eat a TON of power up, and they soften everything...caps by their very nature smear sound by storing energy, then releasing it. No wonder your Maggies are so much more dynamic. Getting the crossover points is crucial to not blowing things up, level matching is fairly easy by ear with the gain controls, and if you have good phase accurate slopes, it should sound even more 3D. I'd love to hear biamped Maggies; that's where they always lacked passively, in the dynamics department. They're time-aligned just by nature too!

Ya sorry it's my first one so it got duplicated from going backward and forwards with the browser. Sorry all.

I like to run active xovers for woofers and subwoofers but find them impractical against passive xovers for higher frequencies such as the tweeter/mid. A lot has to do with the size and cost of the xover components and assosciated phase shifts. A 0.68 mH air core coil (roughly 2.5 kHz @ 4 ohms, 2nd order) is lot less intrusive than a 6.8 mH iron core (approx. 400 Hz @8 ohms). And that's not getting into guage and cost.

Most ribbon tweeters require some sort of xover, or at minimum, a capacitor for protection.

This must be VERY important 3 threads!!

This category includes all modern Meridian systems which also incorporate room correction.

Yes, this is how I've been running my Magneplanar 1.6qr speakers for the past 5 years or so. I built a line-level buffer/crossover using the Linkwitz Labs MT-1 board which lets me duplicate the original crossover frequencies for the bass panel vs. the tweeter panel. I have two Harmon-Kardon Citation-II stereo amplifiers, thus 4 "channels" where each amp output is wired directly to the drivers (soldered directly with no connectors at either end). The amps are bi-amping 'vertically' where one channel receives its signal from the treble part of the Linkwitz X/O and the other channel receives its signal from the bass part of the X/O.

Getting rid of the speaker crossovers was a huge improvement, both in terms of clarity and pace as well as delivered power. The stock crossovers soak up a lot of power! In a typical third-order crossover like Magnepans, as much as 75% of the power is wasted in the crossover (or so I'm told). My speakers are MUCH more dynamic run this way than with speaker-level crossovers.

So, I agree with you that this is a superior way to drive speakers. The Linkwitz Orions fit this philosophy as do the Sandersound 10B speakers or the Emerald Physics speakers with Behringer crossovers. Then there's the whole single-driver camp using Lowther's etc. with no crossovers.

That said, there are many fine designs with creatively tuned crossovers that will NOT sound good driven directly. In particular, phase relationships between drivers and the perceptual effects of phase coherence adjustments are critically important to many designs. Not something to just be applied to any old speaker!

The problem is that it seems complicated for instance ensuring that all frequencies are actively divided and subsequently amplified to an appropriate level. Beyond that issue, there is expense of an amp for each segment of the sound spectrum, this sounds expensive, People have a hard enough time dealing with self powered Sub woofers.
That may be your reason at least for me.
Although I had always dreamed one day of a potent tube treble and midrange with a potent solid state amp driving my woofers (not sub woofers)
