Powering Infinity Prelude MTS

Wanted some input on how you's with the MTS are powering them and which way you prefer.

Do you power them with just speaker outputs from your amp?
Do you power them with the output from your preamp and then your amp?
There may be some with other type systems... chime in.
Which do you prefer? Why?

Have been trying both ways and can't really tell much of a difference except for the bass.

Seems like I get a little more bottom end with direct from my amp.

Short info on my 2-channel system...

Speakers: Infinity Prelude MTS
Preamp: Krell Audio Video Standard
Amp: Krell KSA-250
Cables: Monster Sigma

Jburidan,

Would that engineer know if you're running speaker level input to the Preludes whether or not you're by-passing the subs amp?
I've noticed when I run line level input that the front of the sub gets warm where the sub's amps are. When I hook it up with speaker level inputs that that area wasn't getting warm.
I too could be mistaken... I just assumed that the sub's amps were being bypassed.
I haven't read anything in any of my manuals indicating that's the case. I think some furhter searching may be in order for me to verify.

Joysjane:

I think the plate amp is Class D, so it shouldn't radiate much heat in either case. I don't know much about Class D amps. But I think they were developed for automotive applications.

Hey guys,
Just a follow up after finding out about line vs speaker level input.

Got and email response from Harman...

They confirmed what ya'll said.
Makes no difference whether feeding the Preludes line or speaker level. They both go through the sub's amps.

Thought that was nice of Harman. I actually got a personal response from one of the designers of the Prelude MTS'!

Thanks again for ya'lls input.

Thanks for the update. These are extremely good speakers. It's a shame that Harman quit making them.
