thread for PMC owners

I don't have PMCs, but am strongly considering the Fact 12, twenty 26 or maybe the MB2SE as possible replacement for my Rogers Studio 1.  Would love to hear about your experiences!

Wow. I would have expected more responses. PMC three way design with their Volt 3 inch dome is very similar to ATC three ways. The Volt dome is a clone of the ATC mid range but with a less powerful motor and less useable bandwidth than ATC. The Volt dome has an Fs of 400Hz and useable bandwidth from 500-4000 Hz compared to ATC with Fs of 250Hz with useable bandwidth of 400-4000Hz.

Emulation is the sincerest form of flattery. The PMC IB2S sounds great and is used in many studios and by many artists.

I've only owned the smaller towers but have been on the lookout for IB/MB models just to hear in my own room. PMC was the first speaker I heard back in the day that dramatically changed with the right amp, like night and day difference.

I’ve owned IB2i for nearly five years and think they’re excellent--but to get the most out of them, you really have to replace the binding posts. The stock posts have no place on a speaker of this quality and expense, IMO. Not only do they appear to be cheesy brass, which is bad enough, but the posts themselves are too thick, and set too close, for the use of almost any spades. So you have to use bananas, which isn’t so bad if you tri-wire, which I did for years. But if you want single-wire with jumpers, it gets complicated. The "jumper rods" that come with them do not sound very good at all. So you pretty much have to piggyback double sets of wire jumpers with bananas, which limits the kinds of bananas you can use to ones you can plug into. On top of that, the internal wiring is connected with screws, nuts, and cheap eyelets. Amazingly, they still sound pretty great in stock form, which is a tribute to the quality of the drivers and their integration, and to the design of the transmission-line cabs.

After several years, I replaced the stock triple posts with two pairs of top Furutech posts, combining the tweeters and mids on one and connecting the woofers to the other. I wanted them to be suitable for bi-wiring, or single-wiring with just a single set of jumpers. To accomplish this, I fashioned a new backplate for each speaker from aluminum, drilled it out and painted it black, then installed the posts. (I have to say it looks stock.) Then I connected the hookup wire using Furutech crimp sleeves. The difference in sound was profound, and well worth the effort. And it is all reversible.

It also helps them to use custom Sound Anchor stands built a couple inches taller than the PMC stands. The extra mass (85 lbs, I think) of Sound Anchors improves focus, and the added height cleans things up by reducing floor interactions and some muddiness on the bottom. The guy who owns Sound Anchor (forgot his name) strongly recommended the added height, having made many stands for the IB2 and IB2i for studio and home use.

All that said, I liked these speakers a lot before the mods and love them after. They sound natural and resolving, with terrific mids and bass, and layer exquisitely. Plus, they can energize a large room with ease.
