I said I had a small to medium sized room, but I don't have exact measurements at the moment.
Not very loud, except an occasional loud symphony or orchestral extravaganza. I do intend to use the sub for movies also, but this is of secondary importance.
I have a Marantz 2-channel receiver with a single subwoofer output, so no Bass Management.
Is the bass difficult to manage?
The reviews are so-so. Some say they are great and can't be beat for the money and others say they are fuzzy or boomy, or pop between switching channels or whatever. Many mentioned how great they are AFTER upgrading them.
Are they easily upgradeable? It looks like they have a whole list of parts dedicated for them, which sounds to me like they were really meant to be upgraded. But I'm not a very handy person, so I might want to go with something I don't have to do anything to. I'm not looking to buy just a nice subwoofer cabinet here.
Neverthless, I'm sure I'll change my mind a hundred times before coming to a conclusion!
