I've got a pair of 2.3's I bought new in 1990. They were store demos. I've never thought they had much bass and they went in storage at the end of that year. I hooked them up again about a month ago (it's a looong story!) and had weak sound from the left side, so I pulled all the drivers and checked them one by one. All ok, so I put them back in and voila, balanced sound. Must have been corroded terminals. I then bi-wired them for the first time and it sounds better, but still about as much bass as a good 4" HT tower. I pulled the x over cable and have continuity on the pin to pin, but nothing on the blade. All looks like brand new. I was driving them with an Adcom GFA 555. So then I hooked up a real cheap Pioneer HT unit and when I boost the bass 8 db at 50 hz (the only setting available) it starts to sound full range , although not very good with that component driving them. The SRS effect is strong with staging 3 feet outside each speaker. So what is wrong here? Is the cable supposed to have feed blade to blade and pin to pin? Have my capacitors died? I've got huge coffins that sound about as full range as a Bose cube. Any ideas?
