I'm wondering what the sound difference will be between:
- Rounded vs squared woofer holes?
- Polyfill vs. Norez?
- AV123 auction crossover vs. GR Research kit crossovers?
You could do a search on some of those and find info., or I'm sure Danny could quickly cover the basic differences.
My take:
-The first one is covered, I think, in the thread I linked above. I don't think it will change performance much, but as Danny said...he'd do it! If you have a friend with a router, it shouldn't take long at all. Just make sure to tape the veneer so that the router doesn't scrape it. Do it now while there is easy access.
-Plenty of info. on No Rez in numerous threads. Much better resonance control with No Rez. It will take about 8-9 sheets, so not a trivial cost, but I'm guessing most would say it is well worth it.
-GR crossovers will take many things up a notch, but probably not a monumental difference because AV123 already incorporated some of Danny's Xover parts in the key areas (Sonicaps and Mills resistors). My issue: Why skimp here if I'm going to do No Rez etc...? Of course, Danny might blow us away with a package deal on those AV123 Xovers so it might be very tempting.
