Hi,

Thanks for all who replied my last several posts, they are very helpful for me to purchase my system.

So, over the weekend, I went to pick up the following:

Kenwood VR-4080 receiver
Energy Take 5 speaker set
Sony SAWM40 Sub
4 speaker stands

Each component are suppose to be great. It did sound great, except that in music mode, I feel it's not as full and warm as I heard from Sony ss-MF515 I was considering. Then today, I noticed that my receiver's crossover frequency is fixed at 80hz, while the energy take 5 is fixed at 90 hz crossover. Does that mean, I am missing 80hz-90hz in my setup? How much difference would that 10 hz make?

Prompt answer would be greatly appreciated, cause I need to decide whether to return the speakers very soon.

any one? Please!

It depends on the slope of your crossovers. I'm guessing they'd be 12 dB per octave. From 80 to 90 Hz, you've gone 1/8th of an octave (an octave is a doubling of the frequency). Therefore, the signal (from each source) would be 12/8 dB lower. However, since the crossover is happening from both sides, you're actually only approaching a 6dB/ octave reduction. So... your signal has been reduced by 6/8 dB, or 0.75dB, which is not a perceptible difference to the human ear.

No, you won't be able to hear a hole in your system.
This should not be the problem. Are you sure you have everything hooked up correctly?

Thanks for the professional analysis, which make me feel much more comfortable. I think I hooked up right, the problem, I think, is that the system is not calibrated right. Today, I pickup the SPL from radio shack and adjusted the speaker levels. It sounds much better now. It's amazoning how powerful the sony sub is. I turned it about 60% from the maximum and I still need to adjust -7db on the receiver. :)
