Already in 1970 John Marovskis from the Bronx (New York) designed his extraordinary Janis W-1 subwoofer.The story goes
that he made some 50 cabinets before he arrived at the excellent sonic performance of his system which has a flat frequency response from 30 to 100 Hz. (-3dB).
I tested this pair with Quad 57 and 63, and Beveridge 2 with extraordinary result.
For me is the best sub woofer ever made coupled with electrostatic speakers
Ultra rare and very hard to find one, almost impossible two !
I got those from first and only owner, together the LNC2 Mark Levinson crossover (you can see in second hand section as well)
Attention: you need a crossover and power amplifier.
See on gallery individual frequency response and distorsion, they are incredible.
Please ask for shipping cost.
Maybe will be very expensive
