The midi range, not the tweeter, is the most important driver in a speaker.

I never said the Scanspeaks lacked in midrange. They are wonderful. I only meant to say they also had big deep bass in the right cabinet. Never said they were chest thumpers either.


The integration of a speaker with the room is so critically important and why a good 2-way can outperform a lot of other speakers. Smaller = less problems in the lower octaves.


But ... speakers with built in room correction in the lower octave can perform even better. :)

Yes and no for my speakers. The mid driver, 8” Seas Excel, covers 4 octaves, the tweeters, Seas Millenium, covers 4 octaves. I can’t hear the last one🤭.

Woofers have the first 2 octaves. Crossover at 92hz, and 1440hz. Crossover causes NO issues with amplifiers. Active crossover is between preamp and amps. Amplifier load is just the driver. 
To make K....t happy, no backwave to contain. Open baffles. Bass cancellation? No. Flat to about 24 in my room. Great energy in the all important power range. 
I built these in 2006. Designed in 2004 by the brilliant Seigfried Linkwitz. Orion 3.4. 
No mdf. Hardwood and Appleply.

No room treatments needed with proper sound dispersion. 
Mic drop.

J. Gordon Holt said it first and best:

"If the midrange isn't right then nothing else matters."

You tell 'em Gordo.  RIP.

The most important frequency to measure is 1842 Hz.  
Get that one right, and the rest will be fine.
