Post Subject: Goto unknowns...Posted by serenechaos on: 8/23/2009

Ok; there's a mis-print somewhere, or a manufacturing change...
The web site linked listed SG-370 as 23,000 gauss, and SG-370DX as 24,000 gauss.
The goto brochure lists SG-370 as 24,000 gauss.
And was discussed yesterday w/ someone, one doesn't really know what magnetic strength is unless you measure it.
(after measuring several other make drivers, and finding them to be a ways off from listed specs...)

I did take the 370 apart inspect & measure the diaphram and surround, but have not seen the insides of a SG-370DX.

Yes, the drivers sound good way above 5kHz.
I liked them to 10kHz.
I believe they want to sell their tweeters crossed at 5kHz.

I did not want to run the ribbon clear down as low as 5kHz.
10kHz was as low as I ran it, also tried ~12kHz and ~14kHz.
I liked the ribbon @ ~12kHz best, in that trial, but didn't spend a lot of time with the two together.

Yes, actually I spent more time listening to the 370 alone, without anyother driver supplementing the topend, and without any (low-pass) cutting off the topend.
I don't recall any high frequency distortion, like break-up. I thought the surround went a long way to damping the nastyness often found in titanium diaphgrams, and that it did remain a very detailed, resolving driver. e.g. listening to individual strings in the orchestra, or what I thought it did really well was the upper register of piano. The percussive element of the hammer-fall, and the harmonics of the notes when listening at first, then music...
