2 Channel Subwoofer connection

Hello, I am seeking advice for a Subwoofer connection.  My system consist of a Rotel RCD 1570, Jolida JD 202 Integrated Tube Amplifier and a pair of Bowers & Wilkins 705. This set up is just for music listening.
I like how much detail I get from the music with these 705, the only problems is that my loft is an open space with high ceilings, therefore, the bass is not very strong. I thought I could add a Subwoofer. The issue is that my integrated amplifier doesn't provide a Subwoofer out. The only option will be to run speaker wire from the integrated into the Subwoofer's speaker level inputs, then connect the 705s to the subwoofer's out (As pictured in the diagram)

However, as I've never attempted this connection, I am concerned this could degrade the audio signal, would the sound quality be affected due all these extra wiring and having the signal go through the subwoofer and then to the 705 monitors?
I've looked into the Bowers & Wilkins ASW750  but this doesn't come with sub's level inputs. I am considering the ASW300 instead. Any advice will be much appreciated.
Thanks,

Joseph

Hi Matt,

Thank you so much for your advice. That's exactly the type of connection I was aiming for-as that's my only option- because I don't have a sub out on my amplifier.
However, my main concern was if I will be degrading the sound quality by running the signal through the subwoofer vs the current set up (amplifier connected directly to the speakers).
By the way, I currently have them bi-wired. Would you recommend bi-wiring from the amplifier to the sub and bi-wiring from the sub to the monitors as well?

Thanks for your time.

Thank you all for the useful advice. I will certainly look into the RELs and the other brands.

A couple of questions though. By keeping the main speakers connected to the amp and then running a second set of wires from the output taps to the sub, there won't be need to adjust the phase adjustment knob correct? 
As it sounds like they will be in sync for what I understand.
Finally, regarding bi-wiring. Currently my main speaker monitors are bi-wired to the amp, should I bi wire to the sub as well?

Thanks.
With the recommended set ups I would just need a passive sub. However, most subs are active. Does it make any difference to buy an active sub and use it as passive? Would the active sub be on all the time, thus generating unwanted interference, even though it will be used as an active woofer?
