Waiting on 802D3 to arrive -- Will I need a sub?


It's a rainy gray Sunday afternoon here in Atlanta today. I probably have better things to do but I've spent hours reading and researching trying to ascertain if I will need a subwoofer(s) once my B&W 802D3 arrive here in another week or so.

I can't decide and so I've decided to try posting here and crowdsource an answer, ha ha!

My goal is to create a system that will allow me to listen to 2-channel music for hours on end without fatigue.  The room is my living room and is a quasi open floorplan. It is around 24 feet long by 18 feet wide.  There are 10ft ceilings with an open stairwell back behind the seating position and an opening to my dining room that adds another 400 square feet or so of floor space.

Previously I've had B&W 804D2 towers with two B&W ASWCM10 powered subs.  I've sold the towers and the subs and am waiting on 802D3 to arrive as mentioned above.  The 804D2 absolutely had to have the subs.  The bass just wasn't there without them unless I really cranked the volume up.

So as I sit here I'm wondering if I made a mistake in selling my subs already.  With the 802's will I miss them or will those guys have me covered for 2 channel listening?

If it's likely that I will still need a sub (or 2) what do you guys think would be a good match to the 802D3?

Here is the rest of my equipment in case its helpful in offering an opinion:

Preamp:

·     PS Audio BHK Signature Preamplifier

Amplifiers:

·     Qty. 2: PassLabs XA60.8 Monoblocks

Inputs:

·     PS Audio DirectStream Junior (DAC)

·     VPI Traveler 2

·     Audio Technica AT33EV Phonograph Cartridge

·     Apple TV 4K 

Power:

·     Qty. 2: PS Audio P5 Power Plant

 Other:

·     Pro-Ject Tube Box S Phono PreAmplifier

 Speakers:

·     Bowers-Wilkins 802D3


Thanks!

@auxinput, you and several others who told me not to worry were absolutely right in regards to the Pass Labs amp power. These XA60.8 monoblocks have no problem at all driving the B&W 802D3's. There is MORE than enough power to drive them. I've found that I've been sitting with the volume around 45-50 (out of 100) on the preamp for my listening sessions so far. If I get the volume above 65-70 then it's really too loud to listen to for any length of time. 75+ is enough to get the cops called on me, ha! 

For the first few hours after getting the 802's, I kept the dual B&W ascm10s subs in the room using the highlevel inputs. I would listen to music with them on and with them off.  I tweaked and played with the levels, phase, extension, etc.. but I didn't feel that those particular subs added anything at all to the sound.  The 802's frequency response is just as low as that of the subs, but I thought that it might help with pressurizing the room or giving some extra oomph to the low bass.  I just didn't pick that up at all with my ears and thus removed the subs (and quickly sold here on Audiogon).

These 802's have no problem handling musical bass in my space. They hit low enough to shake the room when I ask them to. In running bass sweeps, my neighbor (and best friend) who was inside his kitchen texted me saying that he could tell I was enjoying the new speakers. 

That all said.. I do also use the space for some television and movie watching (maybe 30%) and am currently somewhat infatuated with the Dolby vision content on my LG OLED also in the room.  For movie watching, I am thinking about adding in an ultralow sub (maybe a B&W DB2D or a Funk Audio 21.0L) just for home theater but I'm pretty certain that no sub would ever be warranted in this space for discerning music listening. I'm always experimenting though so of course I would test that out, ha.

Again.. let me say I have enjoyed all the feedback from the community here.  This thread ended up making the popular conversations section!  I'm kinda proud, lol.  Thank you to everyone who gave me advice and contributed to this great discussion.  

Ps.  I ended up with a different preamp.  The PS Audio that I thought I was going to integrate ended up being on backorder. So after much research, I decided to go with a Mcintosh C1100.  I couldn't be happier.  It's a beauty and enhances the sound of my system.  I tested going directly from the DAC into the amps and then putting the McIntosh between them and love what the C1100 adds to the overall sound.

Pss.  I'm going to post some photos for you guys to show how things turned out in my next post.
Thanks bluesy41

Impressive set up, symmetric and beautiful.  The 802d3 is the jewel.

i told you no subs required once I saw the room, I was right.

once all settles, only a couple things left to play with.

i would suggest speaker wire change, interconnect change, and perhaps try something different than the P5.
