Vienna Acoustics Bach Grand


I'm currently demo'ing a pair of these speakers in my home. It's seeming as if there's a bit of muddiness in the mid-bass. From anybody whose heard these speakers, is this something that could be a function of how much power I'm giving it? I'm using an HK AVR125, rated at 45 w/ch. Highs and midrange seem just fine, in fact it sounds great. Its just when I play something a bit denser, such as Dave Matthews Band or even some of Sting's more recent albums, that I'm finding this type of performance. I don't listen to anything much harder, but if I ever do, I would imagine it would only exacerbate the issue.

I was expecting something a bit more, but wondering if it's the fault of my equipment rather than the speaker. My old speakers were three-way, so I'm wondering if I might need a speaker with a dedicated midrange plus woofer to get me the sound I'm wanting?

Just breaking in a pair of Bach Grands starting today. I was feeling like the upper bass/lower mid-range was a bit overwhelming. then I read this thread and spread the speakers further apart. Tomorrow I will experiment more with fresh ears and an empty house. I do love these, though. FWIW, when I tested them out a while ago they were barely toed in and spread quite far apart.

My general sense with the bass is simply that they produce a lot of it - they are listed down to 35 HZ and that's easy to believe. That's almost the bottom of a piano, by the way. I think they themselves aren't boomy so much as by producing more low end than a lot of small towers (like my old B&W CDM7SEs,) they expose the low resonant frequencies of an untreated room.

The detail on voices and guitars mixed with the strength of percussion and remarkable detail and soundstage really make these things stand out in their price range. They are truly remarkable, IMHO. But spread 'em.
Well, I spread my Bach Brands and changed the toe in. They sound pretty good, although the volume is low right now. Interestingly enough (or not) I moved them without taking any measurements. I ended up with the centers precisely 7ft apart, the center of the back exactly 3 feet from the rear wall and the toe in at about 15 degrees. There might simply not be sufficient volume to produce the mid-bass standing waves but I think they sound pretty damn balanced.
