Spent the day today re-foaming a pair of kenwood lsg-5000's , its funny that you never hear or see much about vintage kenwood speakers but these are domestic Japanese and at 48kg each and a new price of 340,000 jpy the pair which was big money considering ns1000's were 216,000jpy the pair. These are impressive, build quality of the drivers is second to none , the 12 inch woofer has a segmental carbon come like the ns2000 yamaha with an even larger magnet, all flat areas on the driver including between the coil and frame, breather through magnet and top and bottom pole plates are damped with thick felt, The way the driver bolts in is amazing as well, they use 16 bolts each , it sits in a keyway then you turn clockwise and it sandwiches the baffel between the cutouts in the drivers frame , from there the cast mounting ring attaches and locks the driver tight .....all 16 bolts mean its literaly part of the baffel. the tweeter and mids also have huge magnets that barely fit through the baffel cutout , they use a cvt plasma formed diamond diaphragm and around is damped with felt and cork , each crossover is separate and uses no solder to connect components and thick ofc wiring thicker than any of the other yamaha ns1000 type models ive played with , the rear of the cabinet is constructed in a pyramid shape to suppress standing waves and there are mixed types of damping all through the cabinets , baffel has been separated for mids and tweeters and is 50mm thick plus an extra 20mm for mid and hf baffel , almost no info exists on the internet about these except a few japanese sights ive had to translate , these were top of the line for kenwood in the 80's and pretty much the pinnacle of kenwood systems, will need to set up on stands for a decent listen but already i find them better than the diatone ds2000's and super detailed but smooth without being fatiguing, always amazes me the way these big companies built stuff for their home countries for a sense of corporate pride which the rest of the world never got to see if it wasn't for the internet 

 

That's it for today's journey

Kenwood in an underrated brand in my opinion and these speakers look very over engineered in a good way, Will you make stands to match the ones on the brochures image?

Definitely and the stuff they keep back home in japan proves it , yes the build quality and design is amazing on these and allot of other top tier Japanese domestic products , i bought these in from japan so i might just watch out to see if i can find an original set of stands if not ill work something out

Picked up an old Audio Analyse PA-90 stereo amp from dad.

Anyone have any experience with these? Seem to be circa 1970-1980.

 

All working condition, how much would it fetch?

 

It's very rare in Australia - however it's important to bear in mind that this doesn't necessarily mean it's worth a lot.

 

This shows the history of completed and expired ad listings:

No question. Back in the day the Japanese often, not always made superior audio gear, just for their own market. Didn't export any model. Now there may well have been economic and other rational reasons for this, however one must be prepared to try the JDM stuff.. 

 

The Yamaha VFET B-3 power amplifier is an example. Some may argue that its not the very best "vfet" amp that Yamaha made. IMHO the B3 is the best - but never exported.... Might have been to do with the end of the vfet era, and Yamaha were using up the last of their semiconductor stock? Its all speculation...

 

I guess its a bit like the car manufacturers, not every model is exported worldwide..
