Are Rodgers ls3/5a as good as advertise? & Why

(cont'd)

That isn't to say I wouldn't want a pair. I wish I would have bought 10 pair brand new. Just wouldn't pay 2-4 times their original price for a used pair.

You might have had more responses posting in the Speakers forum instead of the Amps/Preamps Forum.

The Rogers had no real bass and the dynamics were not that great but what they had in spades was that certain je ne sais quoi.

The LS 3/5A was a product of BBC research and development. This was a very important speaker for it's time. The final design was licensed to various British speaker manufacturers that were forced to adhere to strict BBC guidelines. The speaker cabinets were made of different types of wood and took the cabinet resonances into consideration when the crossover was designed. The crossovers were designed so that the speaker to speaker matching was better than 2dB. The cone material, a first for any woofer, (a Kef driver) was a new thermal plastic material called Bextrene and opened the door for other poly (plastic) woofers. For it's day, it was a true miracle worker. Superb imaging and decent bass out of a small woofer. The downside....Because it's bass was lumpy,it was somewhat finicky about coupling to a subwoofer. The Kef T-27 was rather spitty. The mod at the time was to remove the screen over the tweeter, and that did help, but the tweeter was prone to slight compression at reasonable volume. But the worst problem was the speakers miserable sensitivity which was 82dB/1w/1m. Couple that with a maximum power rating of 50 watts and you realize very quickly that this speaker was not designed to play loud. With improvements in materials and technology, this beautifully made speaker is no longer considered the sonic miracle it once was decades ago.

Exactly! Sometimes it's a bit of a mystery why some components have that
certain something that lets one simply take in the music and not just the
sound.

Don't know about cabinets or various drivers, but I can tell you about some
experiences with this speaker which may help answer your original
question as to how good (or not) they are; you may be able to extrapolate
some useful info from these accounts.

Years ago (before I became addicted to solder fumes) I was a regular
customer of George Kaye of NYAL fame, to who I would bring my various
tube equipment (including my Moscode gear) for mods. I liked to hang out,
watch George work on my gear, learned a lot of DIY in the process, and
listened to music played over his LS3/5a's which were part of his
"monitoring" system. As some may know, George is an
accomplished jazz bass player, so listening and talking about music
(especially bass players) was very enjoyable. George's mods were always
terrific sounding. One day I showed up to pick up my Counterpoint 5.1
preamp which he had modded and noticed that the Rogers' had been
replaced with Quad electrostats; everything else in his system remained
the same including the Futterman mono's which I had always lusted after.
Coincidentally, that would be my last visit to George as he was moving his
business elsewhere. He had done his usual fine job modding the preamp
except that the Counterpoint now had excessive and thunderous bass; it
didn't work in my system. Coincidence, since he was now listening to his
mods over Quads as opposed to the Rogers? The result of the Rogers'
infamous mid bass hump now being gone?

Around the same time I visited a local hi-fi emporium to audition the Proac
Tablettes since I was in the market for a pair of small stand-mounteds. The
system in the room where I would be listening to the Proacs was set up
with LS3/5A's. Perfect! I knew the sound of the Rogers well and so could
compare the Proacs to them. I listened to the Rogers for a while and as
usual had a very enjoyable relaxed experience and was very drawn into the
music. The Proacs were then substituted for the Rogers. It was an
incredible change in the sound; "detail" not heard before, purity
and refinement that in direct comparison made the Rogers sound a little
rough. Had I found my speakers? I listened for quite a while longer and
started to notice that I was not listening to the music, only the hi-fi. I bought
the Proacs anyway thinking that I could set them up properly in my system.
I sold them a month later. I never did buy LS3/5A's, but have always had a
soft spot for them.

I owned a pair of Rogers LS 3/5A's for quite a few years back in the day, and powered them with a pair of Modded Dyna MkIII's. The Dyna's used Genelex KT-88's. My preamp was a modded McIntosh C-20. Sounded good for many years but then decided to build my own speakers.
