Big Chris:
Back to the OP.
It's like this.... You want a piano in your house. You know a grand piano is the best you can buy, but you live in a 2 up, 2 down, so that rules out the grand piano. Next best is an upright tucked into a corner somewhere.
Speaker packages are the same. Yes, big burly boxes will sound better, but the style system was created because many people (or their Wives) just can't justify or accomodate 5 or 7 big, brutish boxes in their home.
Comparing the 2 isn't really helping. Ask yourself one question. Can I happily get larger speakers into my home? If so, I wouldn't be looking at style speakers.
And this is from someone who is 110% happy with their MT-30s and probably wouldn't get the 685 HT even if I had the space and an approving Wife.
Good Call, Big Chris
