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
