Advice on replacing 12 in woofer in Martin Logan Monolith III's
Thanks for the kind words Steve. I'm glad that it worked out for you. 
Preamp for Halo A21 and/or B&K ST2140
The Cambridge as a Dac/Pre combo will do a good job for you, I think that you'll be surprised at how much better the soundstage is over your Rotel... The amps are a different story... No for me,  I find it a no brainer, The Parasound will be faste... 
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
Oh Marc,  I haven't had a stereo store in 30 years.... even though I had a good run in 12v.  My roots have always been in the Audiophile world. 
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
One of my best friends on the planet is an old timer very respected figure in the audio world.  He uses a 12v crossover with a passive sub, of course, he modded it with some nice parts and built a fully regulated 12v supply, but it does a great jo...

I thought that I'd stop speculating and look these up: Here are the spec's from the Stereophile review:Description: Five-way, two-chassis, dynamic, floorstanding loudspeaker system with four EMIT ribbon tweeters, seven EMIM ribbon midrange units, ...

Hi Marc,   Ok, I'm familiar with most of what you have... The Richter Scale is not really adjustable enough, I was made for a fairly low crossover point for a 2 way with an eq on top.  The Epicenter and the Nakamichi are 12v products...  The Nak w...

meaning which electronic crossover are you using?  
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
I'm going by memory, I could be wrong... What crossover are you using, I'll look it up.  
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
If I recall correctly,  they are at 125, 700, 3k & 8k.... Does your crossover have a choice of Bessel, Butterworth, Linkwitz Riley etc?  Can you change slope? Meaning 12db per octave, 18, 24...or even 64db per octave?  Please let me know... ty...

Here you go,  make sure to ask about the remote... although you can find a universalhttp://www.ebay.com/itm/AUDIO-REFINEMENT-COMPLETE-BY-YBA-INTEGRATED-AMP-/332123967055?hash=item4d542... 
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
I have not triamped these, I've never owned them.  I worked for Marcof/SpeakerCraft, we did alot of custom work and I got these to work on years later because of my time there. I worked on the crossovers only... Measured each ribbons output indivi... 
A speaker that looks like a driver or a driver that looks like a speaker?
@erik_squires Hi Erik, we're on the same page, I only made the comments because of what you said about circles and wide baffle.  Circles have nothing to stop the sound from traveling around the speaker and require even more compensation. On this v... 
A speaker that looks like a driver or a driver that looks like a speaker?
@erik_squires Hi Erik,    You are right on with the wide baffles and circle baffles... In this case, the front baffle is sooo wide, I don't think that it would matter, but it would effect baffle step compensation in the crossover. BSC can be touch... 
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
@bdp24 "The Emit and Emin drivers were good, but the way they were employed left something to be desired; different frequency ranges appeared at different heights, for one thing".This is corrected when you hand match the drivers for exact output a... 
Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?
Hi Marc, Well, I can at least speak to the RS1B.... On the top end,  we found that carefully matching the sensitivity of parts and fixing their output rather than using the pots was noticeable improvement. We never really changed the design, but a...
