I have 4 HTM200's in my theater as ATMOS heights. I'm driving them (along with my Center and 2 surrounds) with a VTV 7 channel Pascal amp.this looks interesting in so many way, do you have them? if yes, any good amp for these?
I'm also currently using a pair at my house in Brazil as mains, driven by an MRX720. One of these days, I'll bring my LX's to Brazil to use as mains and use the HTMs as surrounds.
As to Ascends, depending on your budget, take a look at the Luna V2 (although 4.5" woofer).
