I actually own two pairs of these and i have to disagree completely with Seth.
You must have clean power with plenty of headroom to truly apreciate all that these speakers can do. Let these speakers breathe and they will leave you breathless.
I use an emotiva amplifier to push these bad boys and OMG!!!!
Truth be told, modding the crossovers will only serve to enhance the sound, if done correctly these speakers hold their own against my Wilson Pupps or my Martin Logans.
Bass can be boomy if speakers are not positioned properly in a room so experiment and adjust accordingly.
Very flat waveform with considerable rolloff where it is to be expected, around the 28-30hz range.
No discernable coloration of sound issues or boxiness.
Much louder than my ears can handle

I love these speakers and have for many years.
Almost no info exists about these speakers because they were very rare.
They serve us well in our winter vacation home and take on all duties from movies to dance parties with neighbors without breaking a sweat..
I love these speakers, they retailed for $1200 a pair in 1992 and are still worth every penny. BOTTOM LINE___BUY THESE IF YOU CAN...VERY RARE AND VERY COLLECTIBLE..
