Rare Technics speakers?

Register to hide this ad
Yes they did and I have a pair of The Technics SB - 7000A and they are a very nice speaker with lots of bass . 15 inch drivers .They might be harder to find in nice condition , I am sure there are a few still kicking around . If you get a chance to hear them , let us know your thoughts ?
 
If I remember right their claim to fame was how they were perfectly designed to have all the drivers in phase because of the distance from the front of the box. Time delay? any ways helped them sound very nice.

These have been up for a long time by me. I don't remember what they started at, but it was more than $400.

Technics Linear Phase Speaker System SB7070
14" woofer (think thunderous rock bass)
6" (~) midrange
4" mid tweeter (separate L-pad control)
dome tweeter (separate L-pad control) (think sparkling cymbals)
all voice coils aligned to perfectly phase match the entire frequency range - accurately reproduces for you the sound stage intended by the producer. The pads also allow you to adjust the characteristics for 'flat' or where ever you preference might be.

And they are an impressive presence before you even fire them up!

All surrounds in perfect working order - you have to hear these speakers to prove how accurate reproduction can be!

We are the 2nd owners of these speakers. They were originally bought by my Uncle in Cleveland.

If speaker covers were in perfect condition, this pair would sell for $1000.

Pet friendly, smoke free home.
 
Not really "rare" (maybe in comparison to some of the cat coffins they produced for rack systems) but really good sounding speakers. If they play as good as they look they are worth the price IMHO. If I were buying, the first thing I would do is gently touch the foam under the midrange and watch it turn to dust. That should give some negotiating leverage. Then when you get them clean that off and apply some other large cell foam there. It's to keep the recessed driver from refracting off the top of the cabinet and there is a significant audible difference when it is there.

Yes, foam always turns to dust, why is that?

I never new Technics produced speakers quite like these.

Technics did make some "upper tier" speakers back in the 70's and 80's--I wouldn't go so far as to call them "high-end" by any means, but some pretty solid speakers, but you don't run across them all that often, since very few made it into the US/NA market--they were mainly sold "domestically"--their domestic (Asian market)--kind of like what Yamaha is doing with their new TOTL speaker offerings.

I won't get into a dissertation regarding the chemistry of polymers/plastics, but suffice it to say, we all turn to dust someday. Age, UV exposure, other environmental conditions, and chemical/structural breakdown are the basic answers. I know people that have bought "brand new" sealed NIB/NOS speakers that were 30-40 years old--cosmetically perfect--but still needed all new foams and a full re-cap to make them "new" again.

You also have to realize that we are dealing with "consumer electronics"--it is highly unlikely that anyone designing/building our "beloved" vintage gear ever expected them to still be around, sought after, and in use 30-60 years later. IDK any "real" numbers, but I'd have to "guesstimate" that the average brand new consumer electronics device is designed and produced with an expected life-span of 5-10 years MAX.
 
I had a pair of the SB-5000a's that I got in a package deal a while back. Not my holy grail speaker by any means, but if I were to have only those speakers for a time-frame, I could do a lot worse. I was rather impressed with them for the time that I had them.

I have some of those, they really have some kick. I recapped and replaced the foam under the tweeter. The woofers have cloth surrounds so no problems there. Someday, I will get some 7000s if they ever cross my path.

No doubt, is all part of the "fun" I guess

The fact that you wouldn't call an SB-10000 high end doesn't make it not high end.

I never "dismissed" them, but for the money and the time frame Infinity or JBL blew them out of the market.

Why did you attribute a quote to me that I never said?

BTW, the fact that someone else may or may not have "blew them out of the market" (see, that is a quote) also has nothing to do with their being high end or not high end. Just admit you were wrong and we can all move along.

I'm sorry if you are offended, but the quote was from YOUR post #13 in this thread--I did not mis-quote anything.

I also did not mean to downplay the quality of the TOTL Technics speakers--the point was that (like several well-known manufacturers), they just didn't bring their best stuff into the already saturated US/NA market. Not implying that they were "inferior" to the offerings of other manufacturers, but (and I guess I worded my point poorly) the other "big boys" already had a lock on the US/NA market, and they chose not to try.

This is nothing new, and is still going on. The new (last couple years) TOTL Yamaha gear is still not available in the US/NA market--it is being marketed "domestically"--Japan/Asian market only--and I'd love to try some of it. There are rather regular posts (here, and on other forums) by people from other countries desperately trying to figure out how to purchase Klipsch Heritage speakers and Mc gear, because those manufacturers have not set up a world-wide marketing/distribution network.

I know--and that was not part of me quoting you--that was my post #14.

And again, I apologize, because sometimes the thought or intent in my head does not necessarily make it to a keyboard in any "coherent" manner. I would have to guess that some of the TOTL Technics speakers from the 70's and 80's would command some serious $$$$, because they didn't even try to market them here--but you rarely see them for that same reason.
 
The sound staging or stereo image with depth that many Technics Linear Phase models are capable of should be experienced by all stereo geeks. You have to have owned a pair (and a mere handful of other speakers) along with components that can generate that signal. Some speaker models are not that pricey but some input gear might be. What amp or cd player was affordable that made your technics speakers give a depth of sound ?

Modding is done at your peril. If the sound stage collapses or gets strangely phasey or centre lacking you have done something wrong. The best mod is no mod.
Changing inputs to modern jacks, cleaning volume controls and jumpering protection modules with copper wire I consider to be household maintenance on 40 year old speakers. Changing the original caps on Linear Phased speakers changes the designers specific goals as does changing wire length from xover to individual speakers. Even on a simple model (mySB-T10s) the wiring length can be confusing Jumpering the individual speakerwire with modern wire
of the same length can help wake up a veiled sounding speaker. Then if you made mistake and the soundfield collapses or goes weird you can go backwards. The premium models likely need no wire changing and no no no cap changing. I cannot find the reference to the genius and or team(search Yamanaka crossover) who designed the linear phase concept(bunch of math I didn't understand anyways).
Just my 2 cents.
