    Some people like to have the same speakers behind them as in front for a more consistent soundfield, and some people will use their systems for music - which ideally needs the same speakers all round.

    How much is a complete new Q series 5.1 set up, inc Q900, 600c and 300 rears?

    That would normally retail for £2150, without a sub.

    Thanks, is their room for negotiation in this field!? Q900's seem to be £1200 which is the KEF price as well everywhere! I didn't know if they were like Apple products where the manufacturer control the price!?

    I guess I expected a bit more competition between retailers r.e. prices?:p

    You'd need to speak to your retailer :)

    Thanks, would this cope with the electronic high and the real low bass from dubstep music OK when coupled with a decent sub?

    With a sub, there shouldn't be any problems - it'll all be down to how it's all set up. Which amp/receiver are you using?

    Don't laugh; Onkyo 509... lol! For now at least, was thinking about purchasing the full 5.1 package but don't want to end up killing them with loud dubstep from and low end amp as it's pretty much all I listen to.

    Is only one of the Q900 speakers actually powered and the others just 'tap' into the feed and sing along? I'm not sure how it all works with 4 speakers each!

    I know the 509 won't cut it but that would have to be upgraded as and when funds allow as i'm sure you apreciate :)

    The Q range are pretty efficient, especially the Q900's, so their efficiency will make the most out of your receiver's available output, but just be careful with the volume. Back off if you hear them straining. A more powerful receiver at some point will get more out of them, and show you quite an audible improvement.

    Does this sound to you like those bass drivers are bottoming out?

    My money is on the tweeter in the uni-Q not being 100% perfectly aligned.
    The movement of the mid/bass driver at high volume is therefore enough to 'just' vibrate against the tweeter housing.

    I discovered this on a new pair of Q1's a few years ago, although I thought the new design of uni-Q would make this much less likely to happen.

    The tolerance of alignment must be extremely small so it would be no great suprise if one or two units ship like this.

    I could be wrong though and it might be something else. Doesn't look like it's bottoming out though.

    Naah. The cones aren't moving excessively, so I'm guessing it's just the mic in his phone/camcorder unable to take the volume. If that's what they actually sound like, it could be that something behind the cone has become detached, and is vibrating at certain frequencies or volumes. I had a similar thing on another manufacturers driver a few weeks ago, even though everything on the driver was intact.

    If I was him, I'd be careful though - the Q900's are pretty efficient, but the 508 doesn't have oodles of power....

    can someone explain this amp / power thing and large speakers, i currently us an onkyo 577 which gives 130w at 6ohms attached to my kef xq speakers as in my sig. It seems to drive them very well and also there does not appear to be that many av recievers on the market that are that much more powerful.
    Confused again :)

    Well due to a party the tweeters in my q300's have popped :mad: anybody know if these are available or how much a repair might cost, if it's too much then I might just replace the whole units.

    We've only ever had to replace one, and that was under warranty, so you'd be best to get in touch with your dealer and they can find out for you.

    You'll find most AV receivers don't provide the power they state in the specs, it's usually much lower. They also not able to provide the sort of current (measured in amps) that a 2-channel hi-fi amplifier can provide. Also, some manufacturers rate the power into 4 or 6 ohms, which is falsely inflating the figure. Ignore what's on paper. If you tried a709 or an 809, I think you'd hear the difference straight away, especially with those speakers :)

    The best one you can get then!! :)

    Because of the app I'm using, I can't see which XQ's you have, but I'd be aiming for the SCLX75. It's Class D amplification will get so much more out of them than the 55 will. If you didn't want to spend that much, or can't afford it, save. You won't regret it.

    Afternoon all,

    Just a quick question regarding ohms... my Onkyo 606 lets me select between either 4 or 6 ohms, which should I be running my 5.1 setup at? I have 2 x 500, 2 x 300 and 1 x 200.

    Cheers,
    Indy

    If you set it to 4ohms, it'll cut the dynamic ability of the receiver for safety when running 4ohm speakers.

    so would i be right in saying that if you pair an 8ohm amp with these speakers thats the best/ideal set up?

    are there any 8ohm amps, everyone else I know has upgraded and I'm still on the 606.... 809 is looking pretty tasty though!

    cheers,

    The 809 is excellent.

    You'll only need to worry about 4ohm speakers - any receiver will drive 8ohms no problem, and 6 isn't much different.

    It's not that bad! It's quite average really, it just looks a little big next to the Denons :)
