My study room is 3.2m (W) x 4.9m (L) x 2,6m (H) /11x16x8.5 /

I already have 805s and I would like to install a sub to help out with the lowest bass notes.

Question: should I go with Velodyne DD-15 or should I choose the B&W 825 + Velodyne SMS-1 combo? /Given the quotes I have from the dealers pricewise they are basically equal and I don't have a chance to listen to them in one single place to compare. Use will be 100% 2ch music, all sorts ranging from Jazz to Classic to Hip-hop.

i'd take the DD15

Thanks. Another question: would PB13-Ultra be an overkill for the size of the room? Would it ruin the musicality of the system?

overkill? you're asking the wrong person. :)

no i don't believe having a bigas$ subwoofer will ruin musicality. that's what balancing the channels are for.

If the ultra 13 is overkill then the DD15 is overkill too. (and neither are IMO)

I'd take the Ultra over the velodyne any day of the week. I've heard them both head to head in a shootout involving the ultra13, DD15, Axiom EP600v2 and JL F113. the DD15 came in last acording to many of the panelists (sp?).
