these speakers respondvery well to those complex audio

The other sats and sub provide decent positional audio, while the upgraded center provides fidelity for dialog.

Bottom line - I highly recommend these speakers for anyone who, like myself, thoroughly enjoys great audio but who isn't yet in the audiophile class of consumer.

I never thought I could be this happy with my a/v experience but this audio system, bolstered by the enhanced sub, is absolutely awesome

I've had the HD TV for about a year now and wanted to finally upgrade my sound system to something that would really compliment the excellent HD video with excellent audio.

Since my receiver allows user-defined selection of the LFE crossover frequency, I wired the RM6750 sub to the receiver's sub-out, set the receiver LFE lowpass at 160 Hz, set the sub LFE lowpass to 160 Hz, and set all other RM6750 speakers to "small".My view based on both surround and stereo playback programs is that the RM6750 represents a huge upgrade for folks interested in a basic surround system - particularly if the alternative is listening to standard TV speakers - though the system is not a substitute for more refined audio monitors if the primary content is music.

Performance is great, audio is clean and crisp
