B&W 803D3 + DB1D vs 800D3


Looking for opinions from you all.

I‘m using 803D3 with a listening area around 300 square feet. I want to boost the low frequency for my stereo system.

Considering either adding DB1D subwoofer or upgrading to 800D3.

I suppose the DB1D room eq software is easy and straightforward to blend it with the front speakers.

Please give me your opinons and experience.

Many thanks.

+1, dweller. IMHO, two subs are more optimal in a 2-ch setup. I never felt the need to add more boxes in my 15’D x 30’W room. 
Try a single sub first (the DB1D is my dream sub). IF you can find the "magic spot", then no need to clutter your room with three more (I have such a spot in my room). If you can’t dial-it-in then look at adding more boxes. Good luck and Season’s Greetings!
Two or four subs, not one, is the way I’d go.  The Swarm might be the most cost-effective change you could make.  Best of luck.
