had a chance to look at what Danny posted at his website regarding the 626R. Wading through the comments and pictures, I do see a few points that was not very clear to me:
a) Is there any thing wrong with using the dry wall screw to mount the woofers beside they might not look too nice? If nothing else I do think the drywall screw is actually a much better choice than regular screw because they would bite into the wood better. I still remembered it was very tought for me to remove a woofer from a friend's RM40 because the drywall screws pretty much nailed the woofer to the cabinet.
b) The parts use in the crossover, while not the best, not really the cheapest kind as indicated. I had a few speakers in the past that used electrolytic cap in the crossover (yikes !!). I still remembered evaluating a bunch of some what expensive caps (Hovland, Infinity, Kimber, etc..) about five years ago for my tube preamp. To much of my suprised, the winner was a low cost bipolar Bennic caps (cost about $ 2.00 each versus $ 40.00 each for Hovland and Infinity brand).
c) I used to own a pair of 626R and just heard them again couple nights ago at a friend's house, and I did not recall any cabinet vibration at all. Years ago, I owned a pair of $ 2500.00 monitor audio speakers which vibrate excessively at high volume. I would say the 626R is at least a couple knotches above the Monitor Audio from lack of cabinet vibration stand point. I have not seen any white van speakers so maybe the white van speaker cabinet is as good or better than the monitor audio speakers. My pair of 626R had the sound coat option so this might explain why there were very little if any vibration on my pair?
d) " The odd looking Green tag on the from of the planar mid with a couple of bolts sticking out from it." I did not quite understand the reason for this comments but I do know why the bolts sticking out of the printed circuit board (the odd looking green tag). This was done to fix the intermittent mechanical contacts on the ribbon pannels due to the poor mechanical contact caused by the original punch rivets. It does not look as nice as the rivet but it does works a lot better.
After I read the infor at Danny website, I still don't know what is wrong with the 626R in term of sound when compare to what speakers?
Most of the comments were on the fit and look of the speakers and the part use in the crossover. Prior to MS cabinet, it was no secret that VMPS speakers don't look good. I wish the response graphs of speakers would indicate how any speakers sound in my house because I could just buy audio gear based on graphs and specs and not have to check them out in person.
Once again, I don't see any thing wrong with Danny offering mod for any speakers. But before putting out comments regarding how bad the stock speakers was built/look, I surely hope there are data to show that people prefered the sound of the modded speaker over the stock one in a real listenning environment. After all, a speaker looks good, build with good part, and measure good in a particular test setup, but sound bad in my house does not do me any good.
