    About a year and a half ago, I heard a set of Infinity's (smaller 3 way) a guy was selling. He was selling to get something "better" maintaining the same size. After an audition, I told him IMHO your not going to find anything better in the same size box (he had space constraints). I had put on a song that really showed what they could do and he decided to keep them. Since then, I have keep my eye out and last week I picked up the 8's that were listed here on BT.

    Initially, I ran them dual mono and last night bi-amped, one amp for highs and one for lows (horizontal bi-amping is what I think it's called). My MC 2200's have 1ohm taps, but I'm currently on the 4ohm taps. Any insight on which taps to run bi-amping or on bi-amping in general?

    These are Brazilian Santos? walnut. I found a reference to 2 diff Brazilian walnuts, any insight to which one these would be made out of?
    • Ipê-amarelo / Brazilian walnut (Tabebuia serratifolia)
    • Ipê-roxo / Brazilian walnut (Tabebuia impetiginosa)
    Cheers!

    I'd probably keep them on the 4Ω taps. Their impedance dips below that in a couple of spots but 4Ω is what they're generally considered to be rated at.

    It's worth mentioning that (I think) when using Mac amps with transformers, you'll actually get more total power out of your system by running them in dual mono rather than biamping. Most people don't have the option of bridging when using 4 Ω speakers, but your amps are the exception.

    Yeah !!!! Congrats on those ! I think that's the nicest pair I've ever seen. Man I was serious about driving if you didn't take them LOL how sick am I. I know nothing about the tap deal but with McIntosh power they've got to sound pretty darn good.

    I figured you might just take that drive so I knew I needed to pull the trigger, and I'm glad I did. I'm running the 4ohm taps and they do sound excellent.
