Classic gear from yesteryear; vintage audio standing the test of time.

RE: Only One Way To Know....

The KLH 17's in their Model 20 alter ego were mated to a "claimed" 15 W/ch in the Model 20 compact system. The model 20 woofer was a 4 ohm version to get a bit more out of the little SS amp; but my recollection was that a Model 20 could play pretty loud.

I used my KLH 17's with a variety of amps; both tube and SS and always felt that 30-35 w/ch was about right. The Dynaco XL speakers used a more sensitive SEAS woofer than the original A25, gaining 2-3 dB for approximately 87 dB sensitivity and pretty close to an Advent or KLH 17.

The real key to unclipped levels is the amp's dynamic headroom. A Stereo 70, for example, on dynamic musical peaks, clips at about 45 w/ch, as does the MC225, and so did the Pioneer SX990 I had at the time.
