I had a pair of 9Ls back in the 80's bought them new-powered with a mac 2600-i think was around 500w per channel.I grew up with AR3a the 9's continued with the 3a's impressive low end-but were louder and way more durable-they could pretty much handle all the mac could supply.As much as I enjoyed them I traded for a pair of B&W 802's series 80, and at the time was a big improvment,although few speakers can macth vintage AR low end.
Acoustic Research AR9LS owners? Just for thought
I am the new owner of a pair of these fine speakers and they are in mint condition. Drivers redone, wood polished, new foam in lower cab area... all done right. Original owners manual and recipt from purchase in october of 1984. WOW. Please give me some input as to how these should be placed, wired, ran, etc etc. I would love to talk to some other owners. THanks.
