Agree.? I went with the Regnar Silver upgrade kit for my original 1978 DQ-10s after 40 years with the original crossovers -- and had Regnar do the soldering of all the new components and test the boards and mail them back to me.? The crackling sound (subtle) I occasionally had heard before the new crossovers were installed disappeared.? The sound became a bit clearer and more open, as if a thin veil or light cloth had been covering the speakers before the upgrade.? Otherwise, the speakers sounded the same as before (a bit better and clearer) but still as good, so probably sounded as good as when they were new -- and no more crackles.? For my 63 year old ears, they sounded fabulous and now that my novice soldering skills are tested putting in the newly rebuilt by Regar crossover boards, I will now upgrade my other set of DQ-10s that also have original 40 year old crossovers -- and again have Regnar rebuild the boards and send them back to me for soldering back in place.? They are not cheap, but I figure I will not be around in another 40 years when they need to be redone again, and my enjoyment exceeds the price, which is my litmus test for price/value.

The Regnar kit does use fairly basic components, standard wirewound resistors, Solens capacitors with a sticker over the label to disguise them, etc. Still, though not of the more expensive brands or some sort of exotic boutique type, they are perfectly solid, good parts to use. In fact, if you go with boutique components, performance might decrease as many of those diverge from good engineering practice to chase some woo philosophy that has no merits in actual electronics theory. (Unsealed carbon comp resistors that'll change value as humidity changes, fancy foil in oil caps that are wound so loosely as to be microphonic, etc.) More conventional resistors as you have are well-understood and among the least reactive components in a typical speaker crossover. Going with non-inductive types would be a small improvement, but not significant enough to merit the cost when you've already invested in newer.

?

The only thing I'd consider with the resistors since you've already refreshed the crossovers would be to uprate the two 4ohm resistors in the woofer section to some with a higher power rating. I suggest that due to my experience with a pair of DQ-10s that had, at one point, suffered an incident with the crossover boards catching due to those two getting too hot. (Both speakers had the masonite burn through beneath those resistors and were covered in the residue of the beer that was apparently used to end the impromptu Arthur Brown performance.) That, however, is an extreme case and resulted in the woofers being fried. So, it's unlikely you'll push yours so hard.

?

Whatever you decide, you needn't worry about changing the sonic signature of the speakers for the worse. The tolerances of the original components were so loose that anything newer will be more accurate and fall well within the range of values the speakers were designed for.
