I am looking for speakers for a 5.1 setup. I primarily want something that will sound good listening to music, particularly SACD and DVD-A. In general, I have not been impressed with the sound from HTIB packages. However, Onkyo has a package, SKS-HT530, which they sell as speaker-only package, or combined with a receiver for HTIB, which sound much better than the typical packages.
One thing that I found interesting is the listed frequency response of these speakers. Onkyo lists the fronts and center at 55Hz-50kHz, and the surrounds at 60Hz-20kHz. The lows certainly extend lower than many other HTIB packages, which is why they sound fuller (although certainly not as full as good floor standing speakers). But I was very interested in the 50kHz high end of the range. Most other speakers I've looked at, including very expensive units, tend to top at 20kHz-22kHz. Does this mean that these speakers produce sounds in the higher frequencies that other speakers do not? Are there other speakers, in any price range, that show 50kHz frequency response? Does this even matter, or is that something that really doesn't matter, since we don't hear frequencies that high anyway?
Also, does anyone have these speakers at home, and how do they sound? I've only heard them out on the floor at a circuit city (not in a listening room), and could only compare them with other HTIB packages, and as I've said, I thought they were noticeably better. At around $279 for the package (speakers-only), they seem like an incredible value. If I try to build a 5.1 package around floor standing fronts, I can't seem to do it for much less $1,300. Is there anything in between (in terms of price) that will deliver fuller/deeper sound from the fronts when listening to music, without costing 4-times as much?
Thanks in advance for the help.
