Can Pass XA60.8's drive Revel Ultima Salon2's without their tongues hanging out?
As a point of information, I suspect that the "122 watts peak" specification of the point at which the amp leaves class A corresponds to 61 watts based on the usual convention for defining amplifier power (volts x current with each defined on an RMS (root mean square) basis, rather than a peak basis). Also, according to Stereophile's measurements the Salon 2 has an impedance of around 4 ohms throughout most of the bass and mid-bass regions, where most music contains a lot of its energy, and has a sensitivity of 86 db/2.83 volts/1 meter. 2.83 volts into 4 ohms corresponds to 2 watts, so that sensitivity corresponds to 83 db/1 watt/1 meter. The amp is rated at 120 watts into 4 ohms. It can be calculated that 120 watts into a pair of 83 db/1 watt/1 meter non-planar speakers which can handle that amount of power without significant thermal compression (as appears to be the case here) will result in an SPL at a 10 foot listening distance of about 100 db. That will of course be loud enough for most recordings for most listeners. However, if your listening includes recordings having particularly wide dynamic range, such as some classical orchestral recordings that have been engineered with minimal or no dynamic compression, you might fall a few db short on the brief dynamic peaks of some recordings. Good luck. Regards, -- Al |
