Very helpful answer - thank youAs the 3000 are larger sized speaker with a larger internal cabinet size and the 7000's are sat speakers from a sat sub series, the 3000 will be easier for your AV amplifier to generate musical tones as it will not require the extra effort to drive a smaller speaker.
In question though, it's really all be down to what your using it for, what your happy with and what you can get away with.
Looks wise the 7000 have it for anyone who wants a discrete system, whereas though who are happier with larger cabinets on show will ultimately have a little more fun in all musical areas without having to manipulate the sound though their chosen AV receiver.
@Q Acoustics. Hi, I'm currently waiting on delivery of this 5.1 setup with 3050 fronts. Thinking about spikes, I've got an engineered wood floor so should I use 5p/1p coins etc underneath the 3050's, just like you have recommended with stands for the 3010's?Hello DpM and Nick.M.G.
Firstly; many thanks to for considering Q Acoustics loudspeakers.
Regarding floor spikes and polished floors etc.
We can confirm that the 3000 Series stands come with rubber spike covers. It implies in the manual that you can use them when placing the stands on floors that need to be protected from the spikes - but please, please don't!
It will protect the floor but using the spike covers significantly reduces the sound quality, especially dynamics and 3D soundstage. The best result is to use the spikes (correctly adjusted and tightened) and to place a small metal disc under each spike.
As ShanePJ points out, 5p or 1p coins do the job perfectly at (almost) no cost.
Regarding the 3090C and 3020 combination. This will deliver astonishingly good results. We confess we haven't tried them with the Cambridge speakers on the rear - but can see no reason why it wouldn't work perfectly, provided you can configure the system correctly.
