Upgrading Genesis II's

[Addicted to hifi]

Agreed, still a superb set of speakers. Mine have recently required replacement of the woofers since brown ones were 25 years old. Now I have 201s LOL.

What went wrong with the woofers?

 

[Addicted to hifi]

The woofers on my friends set still look like new.

I have owned original speakers from the 70s and the woofers were all fine.not much can go wrong with them unless you abuse them.

Mine still ‘looked’ like new, but a number of them had sagged slightly such that there was some rubbing. Surrounds still fine, but a couple of the spiders had broken and I’d been babying them for a while. Dog spit up on the back of the right speaker, which I did not notice, put the amp into oscelation, and that was the end of the woofers. Would they have lasted another 10 years … perhaps. Fortunately amp was ok, that’s a whole lot harder (and more expensive) to replace. Bought replacement woofers and wiring, installed them myself, and now no babying.

Thanks for explaining.

Just curious and want to ask, are you replaced the woofers with existing NOS woofers or new one developed by Gary.

With sagging woofers, when nothing is broken, just turn them 180° and you can live happily for a long time to come.

I replaced them with the newer ribbed aluminum drivers sourced from Gary.

Were they a direct drop in replacement and was there anything else needed. Were the accelerometers on the woofers compatible with the amps? Are your speakers the G2 or 200 series.

My speakers are 200, in fact right at the boundary of 200/201. They have the bohlender midrange and taller amp ….. but the brown woofers. The replacement woofers are electronically compatible but physically slightly larger. This meant either rerouting the hole (very messy) or face mounting. I’m a reasonably capable woodworker, so I made MDF spacers. FWIW, I have also recently had the woofer amp recapped.

Some years ago I had replaced the older audioquest speaker cables with the shorter, upgraded genesis version. Less likely to put the amp into oscillation. When replacing the woofers, I had elected to also replace the internal woofer wiring harness. Glad I did as the old wiring had an odd configuration, presumably to combat the oscillation issues.

Anyhow, the new setup has been working well and ironically the amp seems to be running cooler, probably the new caps.

Yes, that was recommended to me and done about 10 years ago. I did not notice any broken spiders then.

Hi Mark,
Just want to ask you about the mid band switch your mentioned previously for crossover.
Part number 212P0112N332RA , is this one a direct drop in replacement for the 3 position switch or we have to modify it.
Regards
Vincent

It is a drop in replacement. Don,t forget to solder the bar across the unused pins on the wafer switch.

Hi Mak
Many thanks and much appreciated for the information, I will try to order some parts for the replacement.

Hi All
Just out of curiosity, just want to know any recommendations for amplifiers which best suitable for driving the mid and tweeter tower.
Many thanks
Vincent

Which amplifiers have you liked in other systems which you found to be musically satisfying and emotionally engaging?

 

[Vin_wang]

I previously like the valve amplifier with my other speaker. I have tried accuphase p700 to drive genesis, it seems sound better with accuphase.

 

[markhof56]

I use Aesthetix Atlas Eclipse mono amps which work great; they are a hybrid, single tube input stage, solid state output. The Genesis Bass amp is connected using the Genesis Servo bass interconnect so is driven by the output of the amp and not the preamp. All other electronics are likewise Aesthetix Eclipse.

I, personally, think many tube amplifiers would sound wonderful. For example, an ARC 250 or 750, VAC 200 or 450, VTL 450 or Siegfried II, Jadis JA200 Mk. II, is what I personally would buy.

 

[Vin_wang]

Thanks Mark and Ron for kind advice, I will do some research and will report back on the future.
