In the Thread: ... again on GOTO Unit drivers...
Post Subject: Audio always as a combo, never a list of componentsPosted by twogoodears on: 8/18/2008
Hi all... yes, a clean power is paramount for a clean sound... I run my turntable and pre-amp on batteries and the difference in sound is amazing, while I never used outboard filtering on amps, BUT I have a public mains transformer at 10 meters from my flat... my 220V nominal are 230V 24/24-7/7-365/365, no spikes.
Returning to Goto: when I quoted the between 7 and 10 years age of my second-hand drivers, I meant to point out they're not the huge, super-expensive, tycoon-type drivers someone own, BUT, nonetheless, were still manufactured in small batches when Seja Goto himself was still in the workshop.
Me too I own Westrex' and RCA's drivers and speakers which are 50 or 60 years old, and didn't suffered any flux loss...
JBL or Altec or...: Romy - an example I wish to tell you is that when I did some testing and listening, what I remember clearly was the hiss coming from high and mid-high drivers... to my surprise, while the hiss from, say, a JBL 2420 with barrier/sliced short horn and lens was like "fffffffffssffffff", quite grainy - the very same hiss, say from interstation FM or tape or phono without disc playing was a feeble, clear "sssssssssssssss" on high and "ssshhhhhhhhhh" on mid-high, quite different from the thicker, less mellow JBL's.
Whatever this means, what I like, now, after months spent on taming, blending voices and listening to my speakers combo is, as Robert already pointed out, they seem to operate in a very specialized narrow bandwidth... a friend which tried my mid-high as a mid obtained a flawed sound, but the very same driver and horn (SG-37FRP and S-400 aluminium horn) used between 3500 and 8000 hz is special, musical, detailed and relaxed...
So, my (humble) advice - based on my direct experience - would be: if the case, try to use Goto as 4 ways, not the more common 3 ways... also if Tanaka-san is, for commercial reason I suspect, also advising and "blessing" for 2 and 3 ways systems... they simply doesn't work this way.
I'd like Jeffrey Jackson would have the time to post his thoughts on his S-150/505 combo and a short description of strength and weakness of his horn system... with some words on sound sure he's more knowledgeable than myself about Romy's question about plate/ratio etc.
Thanks.
