Jamo has a couple of vertical subs that are pretty stylish and inexpensive.
Never heard them though.
Hope you find something you like!
Inexpensive but decent 8" subwoofers
My current setup is Bluesound Powernode (N330) -> Blueroom Minipods
Which obviously isn't a high end system, but balances decent sound with sleek looks.
Looking for a 8" subwoofer which won't break the bank. Bonus points if it also looks good/minimal!
