Ima blog a bit for my future reference and maybe others' curiosity.
After the parade of Polk speakers I have acquired since discovering this hobby, I wanted to hear something a little different, so I jumped on a pair of cosmetically challenged Chorus IIs that showed up on Craigslist. One nerve-wracking drive with the trunk open in an unexpected light rain and ten excruciating flights of stairs later, they've made it to the living room.
Right away, I noticed how detailed the highs are. In a different league from my TL'd 2Bs, 20 year old caps and all. I hate to sound cliched, but I really did hear reeds whistling and fingers sliding on strings that I'd never heard before in my go to tracks for evaluating highs. I'd read that these were among the least offensively bright Klipsch offering, which appears to be true. They teeter dangerously close to harsh, but seem to stay on the right side of that line 90% of the time.
Unfortunately, the next thing I noticed was how bland and frail the mids are. It's definitely there, there just isn't any presence behind it, kind of like listening through a wall. This is with a rather warm tube amp, too; I haven't had the nerve to try them with SS stuff yet. I knew this would be the case going in, but it was still disappointing to have it confirmed. With some experimentation, however, I found that this sound actually suits some genres of music - Nick Cave and Bjork were both much more natural sounding through the Choruses - despite killing all the joy in most rock albums.
As a direct result of the above characteristics, poorly recorded albums are basically unlistenable. I listen to a fair bit of lo-fi and folk punk, both of which send the highs over the edge into gouge-your-ears-out land and highlight just how little life there is in the mids.
The mid-bass is nice and clean, pretty comparable to the 2Bs. I can't comment on how low they dig, since this amp rolls off at 40Hz, so I have them crossed over above there.
I haven't had a chance to play around with positioning yet, but where they are situated now, the sound stage from the SDAs slaughters what the Choruses can do. They do a respectable 100 degree range with a little depth comparable to my Monitor 7s, and the vocals from the phantom center are nicely focused.
Overall, the Choruses are very different, which is to say exactly what I wanted. The SDAs certainly aren't going anywhere, but these will probably replace the second set in my bedroom where I listen almost exclusively to the types of music they excel at.
