not as good as my 4 pi's but quite good considering the money spent. they definately require a powered sub to extend the low end. i'm running them with an inexpensive bic sub and the sound is good midfi. i suspect that these speakers benefit from a good burn in as they were in a warehouse for 17 years based on the date on the warranty card. hey, vintage new old stock, perfect for ebay. i'm going to strip them for parts for a future project someday.

wayne, the resonant frequency for the woofer is 57hz. how low can the response be extended with a larger cabinet without sacrificing too much control?

cheers,

george

You can put them in a 10 cubic foot box tuned for 40Hz and get response flat to 40Hz, the f3 (-3dB) point.
