I have don't claim to be an expert but I have a good ear and work in the scientific imaging/video business so I'm used to commenting on what I see and hear so I'm not afraid to go against the 'percieved' grain of what is posted on here to get my kit sounding to my taste.
The system has been setup with a sound pressure level meter and there doesn't appear to be any gaps.
The PV1 is not used for music (room is 15x12ft) and for movies I set the xover to 120, 100 and 80 to try it all out and settled for 100.
Clearly, there is a lot of personal taste in what sounds best for your ear, furnishings, room size let alone the bias we all have for our own kit when we answer posts.................
In the end, be happy with what you buy and use it - a lot - until you upgrade in years to come and move it upstairs, to a mate, etc. Music and movies have never been a good to see and hear so with the level of kit you are talking about diminishing returns are on your doorstep.
Have a good listen to kit before you buy, try a home demo from a good dealer and then don't rush off to the internet to buy. Dealers can go along way if you're honest with them and they want your custom. I was happy with Divine Audio (personal delivery & setup 120 miles from their shop!) but I have been happy with all the dealers I've used in the yorkshire area.
