Always been curious about the JVC dx1000. Should I buy it and tell you guys about it? Or does this suck so much that it isn't worth it?
Bass is muddy to say the least. Very thick sounding, not worth the time Marv. If you want I can send you a pair around Nov. The new DX2000 (came out with a MSRP of 1000$, now selling for 680$) only changed the enclosure to a different type of wood - nothing else.
So are there actually bass heavy and bass light R10s or just degrees of degradation?
I'd like to see pics of the mold if you find any.
The foam definitely has much to do with the bass, but there are actual differences between the drivers. 1 (serial 1-50 only) is said to be the best in terms of tonality, but I'll need verify this myself with David's #49. 2-3 are the same, while 4 is said to be closer to the cd3000 sound =/
Mikhail did an overview on the 4 driver numbers years back, but I'm not sure how accurate it was.
Where the heck did you find original foam? I've only seen it one place before but they wanted way too much money for it. Did it come with any specs? I've played with some open and closed cell foam rings and the difference between those two foam rings and no foam is huge. No foam makes them sound thin and pretty bright, fatiguing to listen to after a while. The closed cell foam gave the sound more weight but the soundstage and air really suffered...didn't like it. The open cell foam was the best of both worlds and made them sound really nice again. R10 tonality was restored along with the nice airy soundstage.
Anyone looking to do this to their R10s be forewarned that you must be extremely careful if you ever need to take the drivers out. You can easily tear the voice coil leads.
I bought them as a package deal along with a very mint R10 from a collector. He had a stock of foam and new earpads and charged exorbitant prices
. The black foam around the enclosure was never sold, but the guy in that thread spent a few years developing a substitute, which he provides when fixing up your r10s.
But yeah, the damn foam makes all the difference.
