I now have the Lyngdorf MP-50 SSP, Class D amplification (D-Sonic), acoustic treatments & bass traps. I got really curious how well Room Perfect could deal with horns. I have a pair of JBL Studio 580s and a friend trying to sell 4 NIB 590s. It was tempting but too expensive. I decided to start with the KSF-10.5s and see what kind of system (5.1 - 9.1) I could build with a budget limit of $1k.
Now I have the KSF-10.5, KSF-8.5s, KSF-C5, SF-2s, and just acquired a pair of SF-3s. The SF-3s were essentially given to me because the woofers didn't play on one tower. I went to test them this morning and immediately spotted the problem. The shorting bars are missing! Otherwise, it plays just fine.
Now, I want to replace the aluminum compression drivers as described in this thread.
