Question McIntosh and Martin Logan

I decided on the Martin Logan Theos as best choice considering my room. I was considering the Martin Logan ElectroMotion, Magnepan MG1.7 or MG3.7.

Since my room is 10ft wide x 20ft long, it is not possible to have the Magnepans 2 feet away from side wall as they be to close together.

Reason to choose Theos instead of ElectroMotion is that panel area 44" x 9.2" instead of 34" x 8.6" of ElectroMotion.

One concern I do have is regarding using McIntosh MC302 amplifier. Since the McIntosh uses output autoformers, does this effect how well the MC302 will work with Martin Logan ESLs? Is the 2 ohm tap best choice? or should I use the 4 ohm tap? What is the min impedance of the Theos?

Dan, like all M/L stats they dip mighty low albeit inversely, less than 1 ohm at the top of the freq range. I can't say how well your Mac 302 will handle the load, expirement between the two taps and let us know...........

Experiment but I use the 4 ohm tap. The autoformer is an impedance matching device and most ML products are rated for 4 ohm. It dips down to .7ohm at 20khz. There is very little musical content at that frequency to cause a problem. I am using MC402 to drive ML Vantages in a much larger room in a mixed HT/2-channel setup. I will go deaf before the amplifier clips. You will be fine with 300wpc.

Also, you should place the ML speakers 3-4 feet from the wall or look into room treatments.

Let us know which tap sounds better. I have a pair of Ethos and I ordered a pair of MC 601's and they also have the 2, 4 and 8 ohm tap.

Although I am not a hybrid fan, I am a diehard freak on ML, Quad, Maggie and Apogee full range panels. I have been using Mc gears for my CLSes and Quad ESLs for sometime. Driven in 4ohm taps from a MC402 and nowaday with the MC601s, They all handle the power nicely. I dont listen loud, but sure need that headroom for better power control.**

I have been in a group of dedicated Maggie's fan club for years, got lot of info how to make proper room coupling with pair of Maggie in limited space. Provided your current room dimension as 10 ft by 20ft, The Maggie should be placed as closer to the side wall as possible in order to get better bass response and even be able to reach to subsonic level. Never need a subwoofer. Room coupling does the trick. Please see attached picture of one of my group member's system. Pictures show Maggie 3.5 and Apogee set in the middle of the room, Front and rear listening positions. Please forgive me with cell phone pictures.

That was me in the picture. Enjoy.*

Even though I can only hear to about 10K at my age I found the ML Summits as dull as day old dog dung when driven by the MC402 compared to a direct-coupled amp. If you have a 2 ohm tap on your amp it may be slightly better at the high end but you pay with looser bass. More power, such as the MC501 also seemed to help but not enough. You just can't impedance match to 0.7 ohms with a transformer.

I just purchased a pair of Summit Xs and heard them at the store with a Mc 3 channel, don't remember the model, sounded ok. Then heard them with the MC601 which I felt was amazing. Heard then last night with the MC275 which seemed way under powered to me.

Though they're the entry level EM ESL's, I power mine with a pair of MC240's bridged to mono @ 4 ohms. They drive the ESL's effortlessly with plenty of control - all without breaking a sweat.
