I don't know if I'm expecting too much from this speaker or if something is wrong with mine. My previous primary speakers were a pair of Monitor 7Cs, and picked up this pair of 11Ts off of eBay a couple of months ago because I wanted something a little more modern-looking and because I couldn't get proper imaging with the 7Cs with the stands I have and the room layout I'm dealing with.
When I unpacked the speakers, I hurriedly connected one to make sure it worked and to get that magical first listen with the 7C still connected to the other channel. My initial feeling was that the 11T was broken, but it seemed to be much quieter than the 7C, so naturally it wouldn't sound as good. After setting both speakers up and giving a quick listen before bedtime, I noted the positive aspects of them - a less boxy sound and significantly better imaging.
The following day I switched out the old SL2000s (or are they SL2500s?) for the RDOs I had previously put in the Monitors and tweaked everything as best as I could. They sounded GREAT in home theater service, but I felt like I was missing some of that vintage Polk sweetness when I listened to music. It is important to say that I do have a subwoofer which I tend to set pretty unscientifically.
Last night I tried disconnecting the subwoofer to hear what the 11Ts sounded like on their own, and was somewhat surprised to hear a distinct lack of bass. They are in phase and I removed each midwoofer and powered them individually to make sure they're all working. I also did the leak test by pushing in woofers to make sure they're airtight.
I ran some frequency sweeps on DVE through the speakers, and, aside from a little peak around 60Hz, there really isn't a whole lot of action from the woofers below about 100HZ. The specs say that their -3 db point is 29Hz, but it seems like it's more like 150Hz. I tried removing a woofer and connecting it directly to my receiver, and it really doesn't seem like they're trying very hard until somewhere in the 100-200Hz range. My receiver does not have a high-pass filter.
I feel like I've gone on for far too long already, but does anyone have any helpful advice for me? Is it possible for more than one woofer to somehow have gotten lazy or something over the last 19 years? All the drivers and the crossovers look brand new, and there are no mechanical noises. It just seems like they're lifeless in the bass range.
