No, not really.They sound just like my computer speakers!
They sound like my computer speakers
Aha, the QLS-1 speaker is transmission line for the low frequencies, thus the superior bass!The QLS-1s can sound sublime in a larger room, but alas, there would be much weeping and gnashing of teeth if I were to haul them into my larger living room.
That said I'm very partial to the RSII and RS 2.5, really good speakers.
I can imagine them being bettered but can't imagine how
The issue with these type of observations, is that it's never an universal "fact"'
There are many variables
Room is a major one, the amount of people that don't have the actual space for any of those speakers is more abundant than one would think.
Set up plays a major role, especially with these old monsters. I say all this because of people, that might make a choice on any of them. Take in account also that most these old vintage speakers a riddled with electrolytic caps. Definitely consider (upon making a choice) to recap them. And with the kappa 8 delete the poly switches garbage.
Keep in mind results may vary, all and all a very nice review. I never wanted the qls because frankly I find them butt ugly as the rs2.5 and 4.5. But nobody can deny its status amongst the infinity crowd.

Small correction I had the rs1b in black ash veneer (the rare version so I was told) I repaired the controller. And rebuild pretty much that speaker to the point I didn't even wanted to own it anymore. My god never again ...
That's most definitely not a servo controller, it's more of motional feedback system it used. The gamma , beta, IRS v I think the later epsilon used actual servo controlled low end.
Far superior systems
The IRS Beta is so good that it does not sound like a speaker!
.
The qls will never ever come even close to the performance of the beta. That's wishful thinking at best.
That the qls hits 18hz (I wonder even if it can on -3db) doesn't mean anything in terms of shere dynamic range vs the beta. Which inroom hits around 20hz (room gain) not to mention most music ?? Doesn't live in those frequencies at all.
Well I think you might be mixing up some terms, along the lines of Transmission line Speakers, known for reaching lower octives on the bass, and that of the QLS-1's which are Line Sources. The Line Source design isn't about superior bass, but rather a different shape sound wave which is that they minimize the effect of the listening room by restricting vertical dispersion — the sound isn’t affected by the same floor-bounce and ceiling-reflection issues that plague regular two-way or three-way “point-source” speakers. They can also provide sound with consistent timbre and volume over long distances, which is why line-source designs are regularly used for sound reinforcement in a larger area with a full frequeny range. The Watkins Woofer which was a dual voice coil and the large cabinet is what helped the QLS-1 to have a low frequency range.
