I have to disagree with Jaybo on that. The Mani's, when driven by a big amp, have incredible low end response, but without sacrificing the mids. They are low impedance and pretty power-hungry if you want to play them loud. As to your amp, I don't know how well Class-D amps do with low impedances. I'm not implying it won't work - I just have no experience with a Class D amp. I did have the Mani's in my system for a few weeks and I thought they sounded great. I like Totem speakers in general, so I may be biased.
