For those who have spent time with both Acoustic Research AR9's and Infinity Kappa 9's... If you could own one or the other, which would you pick if amplifier choice or room size wasn't a consideration?
Thanks in advance!!
I've heard the 'baby' version of each; AR90's and Kappa 8's. Both very good, and there is no wrong choice.
The 8's might be slightly more laid back in sound, with a softer midrange. The 90's have a very resolving upper midrange, due to their smaller midrange dome. The Emit has better treble extension, but the 3/4" AR dome sounds very natural. Not too hot in balance.
As to bass, both 12" woofers are awesome. The AR 12 has great timbre and tone. A woofer, with good midrange response too, that can surprise in how quickly it can extend into deep bass range, with ease. Two, in the 9, would be epic. The Kappa 8 probably sounded quicker, with better transient snap and detail. Again, two would be awesome.
Now, as I mentioned, 90's and 8's are both worthy speakers. Kappa 9's and AR9's would be as well. Though, the AR9's should be easier to position in room, since they are designed for rear wall placement. Easier to drive too, as AR designed the 9 crossover to keep the impedance of the speaker at a range a typical amp could handle. Kappa 9's drop below 1 Ohm in the low bass and upper mids. This can be very stressful, to most affordable gear. Also, the Kappa 9's need room to breathe, with the dipole dome mid, and rear Emit tweeter. So, you might need a larger room to accommodate the Kappa's?
Me, I wouldn't hesitate to buy AR9's, if the price was right. With Kappa 9's, I'd to give them some serious thought, before a purchase. Maybe this seller could help?
AR9 or Infinity Kappa 9
