Horizontal vs Vertical biamping

I tried both horizontal and vertical bi-amping with identical 2 channel amplifiers. Couldn't really tell a difference or even a difference from a single amplifier.. Stayed vertical, the wiring is cleaner. After I got my set of Magnepan 1.6's, bi-amped vertically for a couple years, then took the plunge into an active crossover with a Bryston 10B removing the passive crossovers. Huge difference, for the better. Started with close to stock frequencies and slopes, but after fiddling around, ended up preferring different settings.

Two points - the 1.6's of that era were known for cheap passive crossover components. Not sure your Legacy's would see the same dramatic improvement. The second point is - I'm electrically challenged. Although the 1.6's are very simple, I had to do a lot of research to implement active, and if I can do it, anyone can.

Read the active vs passive XO link above.

With amp connected directly to the driver, the amplifier is in total control of the motion. If there is ’iron’ and ’paper’ in the circuit, the driver sees a very high impedance at the XO Hz and is "flopping about like a fish out of water" 😉

Bryston makes a good active x/o, but Nelson Pass makes a great one. If it is too rich for your blood, look for his also very fine First Watt B4. MUCH more versatile than the Bryston, and no op-amps or integrated circuits (100 percent discrete circuitry). Completely analogue as well. No longer available assembled (kit only), but very occasionally available used.

+1 bdp24 - excellent 

If you don’t want the best like First Watt or Bryson, Ashley, TDM and DBX make some excellent crossovers for less money. You can always upgrade to First Watt or Bryson after you get your feet wet in bi-amping. Maybe even tri or quadamping like I am.😁

Analog XO like those mentioned are still compromised, just like a passive, in that they have fixed orders and no delay.

IF one listens digital sources, DSP makes so much more sense:

• time alignment
• infinite slope capabilities
• driver anomaly correction
• room correction

dbx and the like are inflexible with fixed orders. On some speakers the drivers lose their blend and sound like individual drivers in a box.
