Only One Way To Know....

Below: Underside of the SC ASR-433. Lots of Auricaps.

Below: KLH 23 (left), KLH 17 (right)

Below: Faceplate SC ASR-433 with black aluminum knobs.

Maybe enough power.....Maybe not.

I have a pair of KLH-17 speakers that I resurrected with the help of Bold Eagle (Jerry) and they sound absolutely glorious with a 12 wpc Stromberg Carlson ASR-433 driving them. Understand, that the power supply has been significantly upgraded so headroom is most certainly better but, it still only puts out a little over 12 wpc (14.4 wpc in 8 ohms is what the tech measured).

Re-sealing the cloth surrounds with GE 100% silicone bathtub sealant REALLY tightened up the bass. Subjectively, the bass went from a really loose sounding 80 hz. To a mucho tighter sounding low 40ish hz.

I have no idea what the efficiency specs are on the sealed box design KLH-17 are, but they play as loud as I care to listen with a push/pull EL84 integrated.

I guess there's only one way to know - Hook 'em up.
