5 speakers for $400 and no subwoofer?!

Total Garbage (IMHO)!!! Plastic (composite) enclosure, 2 1/2" woofer?/mid, and a terrible frequency response. Rated @ 95Hz-24KHz, but the -3db lower limit is 130Hz. How does this make any sense? Real world usable = 160-180Hz @ 0db at best. This is too close to, and on some subs, beyond the LF crossover to the sat's. This will give you a weird (voices out of the sub) mis-directed sound pattern. Plus, the wattage is rated @ 125w for these. There is no way that a 2 1/2" driver can handle that wattage before exploding. My rule of thumb is: Take the watts and divide by 1/2. Now we're looking @ 60w, and that seems more realistic. At $400.00, with NO sub, there are better systems out there. Pass on this one.

What's a good 5 speakers set? I don't need subwoofer as I already have 1. I'm looking for something to setup my 7.1 system.

There is a mirage nanosat setup that is usually on sale here for 200 at Vanns.com. It always gets great reviews, and is a small setup like this one.

Cablephil, sorry but you don't know your frequency ranges very well, do you?

For anyone pairing these with a sub, you'll be more than fine. These are surround speakers, and their purpose is to highlight the midrange. Anything below 250hz will be mostly brought in via the sub channel on any home theater setup. You don't really want your surrounds to pick those lower frequencies up. Your most important range will be 800hz - 12khz for these surrounds.

I don't know what you do, Phil, but I'm an audio engineer. I do this for a living.

#8: ROFL. The Holiday Inn Express was 2days ago. I guess some of it wore off on the 2nd day. #7: bpenney, I don't dispute your cred's, but on most of the subs (on the market) that I looked at, the crossover to the sat's goes up to 180Hz or less. This would leave a hole right at the crossover point. Agreed, the rears don't need the lows, but what about the fronts and center? This system is not just a "surround system". The spec's for all (5) the speakers are about the same, just the # of drivers are increased for the fronts & center. This, in my opinion, leaves too much for the subwoofer to do because the little sat's really don't have a dedicated woofer (none at all) that goes low enough. I would still look for sat's that have at least a 5" or > woofer for the front 3. Most woofers @ 5 > 6 1/2" will still give you good lows and mid's, and will handle more power because of the increased size.
I'm standing by my previous post. At this price, get something else.

Why do people say the rears do not require low frequencies? THX certified systems require your rears to reach 125 HZ and the fronts should reach 80 HZ. These speakers are not even close. My rears and surrounds can reach 60 HZ if needed. Listening to movies I can hear frequencies below 120 HZ during battles and gaseous explosions coming from my rear. These will work with a sub but it will sound like any other tiny speaker system (thin). Most subs should not have the crossover set any higher than 120 Hz because they are not designed for theses ranges. You should avoid surround speakers that do not at least reach 120 HZ. Sure you can save money with smaller speakers but you would have just spent $600 dollars on a system that will leave a lot to be desired. Man up and spend some money or buy used quality speakers on craigslist. It will be worth it in the end.

#7 A lot of scenes utilize frequencies well below 250 HZ output through your rears and surrounds. It's nice to have the range when needed. Also these are meant to be used as fronts as well and they are in no way adequate.

#2 nice posts.
