I auditioned pretty much everything at guitar center a couple months ago. I liked the Mackie MR5mk2 the best. I wasn't looking to mix on them though. I was thinking of hooking them up to my TV in connection with a sub. Ultimately, I decided to keep looking for something else. At $150 each though it was tempting. I heard someone say they preferred the Macke MR5mk1 to the mk2. I got to thinking about trying to find the mk1 on ebay. You really need to listen for yourself though. The thing I have been really looking for lately is a very clear, yet non-fatiguing mid-range. I have auditioned several speakers for my TV in a fairly wide price range, and none of them have had a better mid-range than my TV speakers. I think the TV is using a wide-band 2.5" with maybe a 6" helping as a kind of a sub. But the vocal duties are clearly handled by the single small wide-band driver. I also have another speaker with a single 4.5" driver and it is really good with television. So far anything with a cross-over has seemed flawed. On TV, speakers with cross-overs are always exaggerating the higher frequencies. It might seem like you're getting more detail, but really, you getting weird distracting sounds. There is also a distinct drop in vocal quality. I didn't originally notice this. But my mom who is very hard of hearing, can hear the TV pretty good on either single driver, but has a very hard time hearing the TV with any of the speakers with cross-overs. So, lately, I really prefer the smaller drivers, and hope I can integrate a sub. I also listened to the QSC K10 and QSC K12 PA speakers. I didn't think they sounded nearly as good as the Mackie mr5. From that comparison, it just seems like the bigger drivers are incapable of sounding as clear as the small drivers. I am sure the QSC would sound good played very loudly in a large venue, but up close at low volume, it wasn't even close. My single driver 4.5" make all music sound good and they are completely non fatiguing. This might not be the way to go for making mixes. If you mix on a bright speaker, then your mix should come out a little dull, which probably sounds better than the reverse situation. Especially since I think most speakers with cross-overs are already bumping up the higher frequencies. I may be wrong, but that is what I am currently thinking.
