Hi guys, I bought a pair of 4530 clones today. I missed out on the 4520's on Ebay so I thought I'd give these ago. I loaded them with my 2220-H's and mounted a pair of 2370/2420 combos on top. They sounded ok but not very musical. So after trying a couple of other bass drivers ( K-140's and even 2235's) I went back to the 2220's. So then I replaced the horns with my 909/511b combos and everything started to come together, I crossed them at 500hz and turned down the 909's a little and was very suprised how smooth the sound became. I will need to spend some more time with them but so far pretty cool. I may hook up one of my 18's to find a little more bottom-end. I may try some 808's on the 511's as well and see how they go.
Some thoughts would be appreciated. Also this week I hope to recieve a pair of E-145's I'd like to try them in the system as well.
Cheers!
