Who makes a 4-way speaker besides Revel?

You don't say if y ou are looking for new or used...but if used, then the NHT 2.9 and 3.3 are both 4 ways and bi-ampable.

unless the ar9's are somehow going bad, they will compete with many speakers out there at 10 to 15k and beyond....still a benchmark design, and they wrote the book on 'balanced' sound....think a long time before replacing.

Thanks for info. Jaybo, glad to hear your opinion that 9's are still competitive. Haven't auditioned any really high end speakers. Might be better off then to rebuild crossovers. I refoamed them myself but am afraid to tackle crossovers. Sounds like the guy selling rebuilt H/K on audiogon would be up for it.
Was thinking either new or used. Thanks. Lynne

Forgot to mention--nothing is wrong with the 9's. They still sound really fine. I guess they'd sound finer, though, if the crossovers were upgraded--so I'm told by various sources. Lynne

ar's finest ever for sure.
