Right, backhome now and on the laptop.
If you said to me that you were going to use the speakers for music I would suggest you stick with the missions.
However, in my circumstance we are soon to be looking to sell the house so the missus wanted the av kit tidied up.
I used to have some XTZ floorstanders and centre which used ribbon tweeters but they were large and along with my SVS cyclinder sub, took up alot of room.
Having moved to the M&K speakers I must say that they are a lot louder than the XTZ's were at a given volume. I can only assume that it is down to the difference in ohms and the design of he speaker. In terms of movie enjoyment the M&K speakers really shine. The M&K speakers have a little extra "magic" when it comes to movie as they seem to create nuances (sp.) in certain areas that was not apparent with the XTZs. They are certainly very dynamic. I would not say they are ten times better but they are certainly marginally better than the XTZs by the simple fact they love to be driven loud and love to throw out or embelish on sounds the XTZs didn't (which is a bonus IMO). For music there is no comparison the XTZ win hands down.
For general tv viewing they definately lack the fulness of a floorstander as the sub LFE gets much less use. It's much lighter in the bass department. I can dial the sub level up on my processor to compensate but this is a bug bear with low level input regardless of the sub / speakers. It just becomes less of an inssue with full range speakers as they provide more of the frequency range.
I am actually contemplating changing my sub and going for a sealed option.This type of sub design tend to offer more mid-range slam which will help the M&K's. The SVS is definately no slouch but its more at home in the lower frequencies than punching you in the chest with fast, clean bass. The increase of speed delivery I feel would benefit the M&Ks immensly.
In terms of WAF the M&Ks win hands down. They look great and once I decide on my sub they will be wall mounted so my AV kit looks neat and tidy.
