Hi I'm new in the forum I have a B&W setup with 802 D3 HTM1D3 and 2 Velodyne DD12+ subwoofers. I would like to know what crossover do you choose when listening 802D3 for 2 channels music ?

You can go a few ways. First find a good sub setup instructions on the internet. Placement, room acoustics play a big role on dips and highs in bass. Currently I have my 802N set to cut off at 50hz. I would guess you could go much lower with your 802D3’s. For me, I couldn’t move my sub around, only one place for it. I found some good bass sweeps and used a really good sound meter to measure the dB’s through all the lower bass ranges.

Kal also suggested another to achieve a flat response. Look at his earlier posts in this thread.

Thank you very much for your answer. My sub have perfect placement in the room and run flat from 20 Hz to 200 Hz. I don't know if subs should have crossover set at 80 Hz for a perfect overlap or if it's better, with such good speakers as 802 D3, to let them play say and set the crossover to 50 Hz (I know crossover is not a brick wall...)
When I try say 60 Hz bass is stronger but I hear some dynamic loss. Perhaps time alignement problem or the woofers of my sub can't match the velocity of the 802 D3 woofers ?
The 802 D3 are powered by classe CT M600

These are great questions JoSoSa. I have a smaller but similar setup also and have experimented too much with the Velodyne settings. I run at 45 Hz. What is your slope set to?

Hi robd2, I ended with JL audio recommandations :
https://jlaudio.zendesk.com/hc/en-us...udio-Subwoofer

80 Hz crossover 24dB slope, most important is Group Delay if you have a processor or Impulse timing

The idea is to declare the sub(s) 12 feet further the speakers (L, C, R but also LS RS). 12 feet works ideally with Velodyne subs and JL audio subs. So if the mains are 7 feet away the sub must be set at 19 feet of distance.

I have 802 D3, 2 channel only. I mainly listen to jazz and rock and roll. I generally stream hi-def from tidal, CDs and listen to high-def files from HD Tracks using J River.

I've never used tone controls, and I've never used a sub.

Everybody likes what they like, the only way to know if you like a sub or not is probably to try one out and see for yourself. Maybe your dealer has a decent sub you can take home and give it a try before committing to making a purchase.

If you're anywhere near Connecticut, I have a CM 12 sub that I used to use in a 5 Channel set up, you're more than welcome to borrow it and give it a try. It probably wouldn't be a perfect match to the 802 D3, but it would at least give you a flavor of what a sub would be like.

When I had the 802D2's I didn't find the bass output sufficient, which resulted in purchasing a JL Audio F110. A friend who was previously a 802D2 owner and now has the 802D3's, finds the bass output is much better than the older Series 2.

802D3s-subwoofer is a luxury in most rooms.
