• As with any on-wall loudspeaker, for true full-range sound you're going to want to add a sub to round out the P460's performance.
• The P460s can play pretty loud, loud enough for most consumers I'm sure however if you take them past their "happy" point they do begin to break up and distort, which is normal and something you'll run into with any compact on-wall. If you want bigger sound you'll have to step up to bigger speakers, most likely monitors or floorstanding.
For $699 apiece or roughly $3,500 for a complete surround sound system you could do a lot worse than the P460 from Boston Acoustics. The P460s are priced right, look great and sound phenomenal provided your room and tastes don't stretch the speakers beyond their limitations. The P460s are designed to flank larger HDTVs and compliment them with bigger, theater like sound. I say mission accomplished.
