I had some time today and took the 1.2's put them on the 4 ohm tap of the McIntosh 2105 amp.
The difference was big!! It seemed to play a little softer then the 8 ohm tap ( I thought it would be slightly louder but it was not) but, it was more coltrolled. the highs was a bit softer and not as harsh, the bass was more tight and just seemed to have a more pleasing sound. When I did it, I only thought it would be a volume change, not a sound change... Has anyone else noticed this? I do know many amps do not have taps for specific ohm's so I gues the questions is kind of limited on people who can or have changed it on their amps.
The tighter sound is what suprised me. Tighter all the way around. I used Lorna Hunt all in one day CD and the Cars Shake it up Mobile Fidelity version cd's as test cd's.
On a side note, anyone that likes cowboy junkies, pick up all in one day!! or ask me to burn a copy since it is out of print. Great test cd.

1.2's are closer to 6 ohm than 8 ohm. When the speaker's input impedance matches closely with the amp's output impedance, the best coupling and damping will occur. I suspect your amp and speaker's impedances are now optimized.'65 427 Shelby Cobra

Sounds good. I have a Mac 2100 and always wanted to try the 4 ohm option. Thanks for the post.

hey vette, did you try it out? Just wondering if you heard the same thing I did?Klipsch The Nines, Audioquest Thunderbird Interconnect, Innuos Zen MK3 W4S recovery, Revolution Audio Labs USB & Ethernet, Border Patrol SE-I, Audioquest Niagara 5000 & Thunder, Cullen Crossover II PC's.

I did it last night - Couldn't agree more. Good call.

Sweet I am glad it was not just my imagination! LOL To me it was night and day.... I did not have to do extensive listening to hear a difference.
I feel like i got a new system! LOLKlipsch The Nines, Audioquest Thunderbird Interconnect, Innuos Zen MK3 W4S recovery, Revolution Audio Labs USB & Ethernet, Border Patrol SE-I, Audioquest Niagara 5000 & Thunder, Cullen Crossover II PC's. -
Not sure about night and day but def. alot better. It was on my list of things to do but thanks for the reminder.
Going to be doing more listening tonight.
