As above. If you want to know detailed specs, it's available on Q Acoustics' website. This is the second generation of this speaker with better external finishing and supposedly slightly better innards.
Reason for selling is that I've upgraded to the insanely good KEF LS50 Wireless. About 2-and-a-bit years old and outside of warranty but has been working perfectly and well-treated by someone whose musical tastes mainly revolve around classical music and French/Italian pop doing near field listening on a desk whilst working. It rarely (as in under an hour) has been driven beyond 80% of max volume. It has RCA, optical and BT inputs and can support a subwoofer.
A bit of subjective opinion and evaluation of likelihood good use cases
Throwing some of this out there to avoid disappointed audio buyers.
This is seriously worth your consideration if you currently run a set of your typical computer speakers or dock worth up to 1K and would like a solution that provides a truer sound quality and much better soundstage (i.e. not that "boxy" sound). You obviously need to be happy to get your music into the speaker via a computer or another solution. You will likely value quality of sound over just sheer volume.
Alternatively, if you would like to go to a good quality low cost 2.1 solution and want to move away from a lower cost soundbar for your TV/gaming, this is also worth considering. I've found dialogue to be crisp and clear, with again an excellent sound stage and imaging.
I've listened to a lot of active speakers under $1K and nothing other than the Yamaha set that the music schools recommend for kids learning music has a more "reference" sound. You will find that everything under 1K retail is "tuned" to some degree but the sound on this is still far less "staged" than say the Audioengine HD3 or H5+. Normally I'd take What Hifi's reviews with caution but they are pretty much spot on.
Costs and other details
$400 and it's yours. Its availability in retail is quite limited but sells for around $800+. Buyer must pick up. If you are keen to do a deal and/or can wait for a mutually suitable time, I am happy to coordinate with you whilst I do a trip down to Zealong in Hamilton (potentially this week or later) to facilitate a pickup by someone living in the mid-to-lower NI. You will get the speakers, the remote, speaker wires, optical cable, and power cable.
