Hello. I have a pair of some very old speakers from a Technics system. The following info is available:
MODEL NO.. NB-304
SYSTEM: 12" 4 WAY
COLOUR: RG WLNUT
15-07-003
Does anyone have any idea about it? Also is this kind of very old equipment worth selling?
Per the replies above -- I, also, have no idea.
I am
guessing, and this is
absolutely a guess, that, if that model number is correct, the loudspeakers may be from a "rack system" of the type that became (briefly) popular in the early to mid 1980s. If so, they're probably unremarkable at best, and likely of very little value sonically or financially.
Technics, interestingly, marketed some "rack mount" systems containing rather high-end components, but they were
before the low-end, low-quality "rack systems" I refer to immediately above.
I did look for anything (including rack systems) from Technics with a '304' in the model, but I didn't find anything.
A photograph of one of the loudspeakers you are asking about would be
very helpful.
The rack systems of the '80s usually included loudspeakers featuring rather flimsily constructed ported particle board enclosures, inexpensive cone drivers, and minimal crossovers (often just a capacitor high pass filter on the midrange and tweeter drivers).
Here's a googled photo of 'typical' Technics rack system loudspeakers of the time.
Those interesting looking "horns" on the bottom are almost certainly cosmetic trim for the bass reflex ports, meant to resemble much more interesting Technics compression treble drivers loaded with horns.
Here's another borrowed image (from Reverb), although these Technics loudspeakers have had the original tweeters replaced by what look like CTS phenolic ring (cone) tweeters -- or knockoffs thereof.
