Have a set of DQ-20s Ive been using 4 years. All drivers original and working. Recapped the crossovers with premium caps (except the 5ufs which used cheaper Daytons) and refoamed the woofers the day I got them- nothing to compare them to. Bass, midrange, image all fantastic- but the upper frequencies are flat and I cant imagine what they should be. I pulled on old set of ADS speakers out to sell and when I auditioned them for the guy, realized how much high end Im missing. So a few questions-
Did the original Scanspeak D2008 8517 tweeters have ferrofluid? Ive changed old dried out fluid in vintage tweeters before with great effect.
I heard there is a mod to remove a 5uf cap to the tweeter like the DQ-20is have- would that be a potential fix? Also considering running a bypass cap on the 3uf to the tweeter.
Anyone have experience with the Hiquphon OW1 tweeters or modern Scanspeak D2008 tweeters? If the Scanspeaks, I see 2 models- one with ferrofluid and one without- which would be the correct choice? If the Hiquphons are a major upgrade I dont mind spending the money as these are my everyday speakers.
Thanks in advance.
