Hi,
for me it's difficult to think of more than two ( coherent or not) sources of sound playing together; I mean, it's a huge job to make 2 channels working and produce excellent results. And i don't know how others apply their excellence mark criteria.
If it's for budget...well the Statements use woofers with foam surround, right ? Usually it has to be changed every 10 years ( or maybe not ).
As for the multiple woofers...I'll have one, thx

Multiple woofers are allowed only for sub-bass duty, as the source doesn't need ( and can't ) be recognized and located . For an instrument, I don't like to have it spread all over, it's a matter of attribution and knowing the location of the sound, where it's coming from . And who produces it .
Other than that, I don't have any clue of where to start from

A classical 3 way with woofer-midrange-tw might be more appealing.
Or two way ...with a waveguide around the tweeter.
A 6.5'' woofer is ok for home; also littler ....
