Let's see ... I have a pair of Quantum 2s that I'm currently working with a third cabinet to convert to a mirror-imaged pair. There's also a pair of Reference Studio Monitors and RSbs (the next model down) in use as rear channels for the former and a bedroom system for the latter. I've also an extremely rare pair of ES-1 electrostatic headphones with the ME-10D energizer.
I'm a bit lacking for pictures, but here are my Quantum 2s in my system as it was way, way back in September 2004. Very much has changed since then as this was my first foray into good audio.
The Q2s weren't fully operational at the time thanks to broken tinsel leads on the domes, but I was using the Watkins woofers as stereo subwoofers for the Magnepans. It was an excellent combination as Watkins bass is just as tight as it is deep.
And a picture of my pair of ES-1s. I've been having a bias voltage problem, so they're not working yet. I'm not going to give up on them, though.
These are early pics when I first received these, so please pardon the holy woofers. So, pics are "as purchased" from an Ebay seller in Toronto for a very reasonable price. These were one owner speakers, purchased for 1800 $CDN in the late the 70's I was told.
Woofers have since been refoamed and the diaphragm replaced in one Emit tweeter. Still have to purchase a power resistor for the Midrange driver xover circuit in one speaker. Have removed, cleaned and re-installed the control pots in one speaker (currently have the woofer out to do the resistor). Will do the pot cleanup when replacing the resistor in the other good speaker so it matches the resistor in the broken one.
Unfortunately I dinged these otherwise pristine cabinets in the moving process. :tears: They are brutally heavy even for two people to move around a house. (Next pic)
The significance of this next pic is that there is no rear Emit Tweeter on the upper rear panel. Some versions had one here. That round piece of cloth covers a port that I "think" goes to the back of the Mid-bass driver, but needs to be confirmed. It's a design feature I would like to understand more about (for another thread).
Junkaudio,
I always have a difficult time describing the sonic aspects of loudspeakers as well. I can say this though, the RS1, RSII's and RSIII's are known for great crossovers. The great aspect of them is that they have a very steep octave rolloff which forces the appropriate signal frequencies to the correct drivers without overlaps. It is the overlaps that create a muddier sound in that a driver is handling a portion of a frequency that it is not best suited for, oftentimes driving them past their designed limits. That is maybe why they sound fast to you, because the steep rolloff provides a 'fast sound'.

I have a set of RS 1.5's and love them. I was going to sell the drivers and crossovers to JP and as our talking back and forth progressed my curiosity was raised and I wanted to hear them. Well, I feel bad for getting JP's hopes up but I sure did discover a great speaker that I had owned for around 4 years. Glad I took the time to put them together and have a listen. Here are a few pics of the ragged out cabs. I have the drivers complete but am still using the cabs. The pics can be seen here: http://audiokarma.org/forums/showthread.php?t=54521
RS4001's in my living room on the HT setup. (one wonky mid though if i press lightly on the upper edge it will stay on for awhile) I'm having a hell of a time finding a replacement for the original polyspherite mid.
I have 2 sets of Quantum 3s ,both work excellent and have had the woofers refoamed an d I have done some tinsel repairs on the midranges.1 set I redid the crossover to allow biamping.The other set has a hole someone cut in the front of cabinet to install a Hpm tweeter when the emits went bad.I installed emits and disconnected the other tweeter.Cannot see it behind the grills.I also have some Quantm jrs and 2 sets of WSC 1a's.These are the original speakers that Wlliam Watkins designed for the watkins woofer before he sold his design to Infinity.They are 3 way with paper cone tweeters and mids with the dual voice coil watkins woofer.Exceptionally fine speakers .I also have some rs8a in my living room for home theater setup.Hopefully I can get some pics later.
