The Model P315 HO (High Output) is very rare and is considered Acoustic Research's last real effort at a world class full-range speaker. They retailed for $1995. I've owned several pairs of the legendary AR-9s and these do indeed stack up well against them.

The speakers are in very good cosmetic condition and work without any issues. The cabinets are free of scratches and have only a few very minor dings. All drivers are completely free of any damage. The foam woofer surrounds is still very stiff and firm with no signs of aging or deterioration. The mid surrounds are rubber and will never wear out. The tweeters are protected from dust and damage by a fine gauze and are mint. The foam baffle and waveguide ring around the mid and tweeter units is still good, though not mint, as seen in the photos. Nothing that will in any way effect performance. The one issue is some cat damage to the cloth on the front grills, one worse than the other, which would be best to examine in person if that's an issue because such snags are hard to photograph accurately. There is no damage to either side grill covering the woofers.

Here is a link to ae lengthy review of the speakers by Stereophile magazine for the Acoustic Research AR1. By their own admission this is essentially the same speaker as the P315 H0.:
