Someone tell me why I shouldn't buy this instead of a horizontal center speaker. The latter would probably need an amp which makes it a less appealing option.
You should buy this instead of a horizontal center speaker. Most MTM and similar center channel "bar" type speakers are terrible.
I just started using an IN-8 v2 as a center channel speaker with my Genelec speakers for the left and right and it works well. At some point I'd like an 8361 for a center but we'll see.
For now considering the dispersion, SPL, placement correction, and having a built in amp, I'd go for the Kali over any other center besides one of the Genelec The Ones models.
