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!

Dave Wilson sells subs. I recently sold a pair of mint condition Witt series II. Now I have Legacy Whispers and never had a need for subs with either pair. When I ran Klipsch (Chorus, Forte and Quartets) and Lipinski L707's I used subs. I think Bryce should give his new speakers a chance first, then add them if needed.
The bottom octave is a bitch to reproduce, and very, VERY few speakers are up to the task. To require them to try compromises their ability to reproduce 40Hz and up cleanly (due to the distortion the woofer creates by trying to play below it's capabilities), and does the same to the power amp(s) driving them (low frequencies suck up a lot of power). Some music doesn’t suffer too badly when reproduced by a speaker extending down to only 40Hz before rapidly rolling off (many, if not most speakers, at least to live music SPL), as the lowest note of a "standard"-tuned 4-string bass (electric or acoustic)---the E string played open---is at 42Hz. Some rooms become boomy if pumped full of bass, so some people prefer to not try at all. But in a room allowing good bass reproduction, and subs well-positioned and adjusted, that bottom octave can be really fulfilling, and help make some reproduced music sound considerably more like live that if it is missing. I especially like how the acoustic of a large theater or church/cathedral becomes apparent by the bottom octave reproducing the very low frequency, very long wavelength soundwaves those spaces create. Your listening room sounds HUGE!
12 days ago you had $5K to invest/spend and now you say you just purchased $22K speakers???

Years ago when I trained at Sumiko on how to set up speakers, they had a pair of SF Stradivari (rated down to 22Hz) with a REL Studio 3 sub. They played solo violin recorded in a huge venue and all the space of that place along with the emotion of the musical selection was revealed. They then played the same piece of music with the sub disconnected, and the sound completely collapsed to where it just sounded like a nice hi fi. As REL says - It's not about the bass, it's about the space. Plus, no other subs in the industry can be fine tuned to seamlessly blend with main speakers like RELs can. If budget allows, considering your room size, get REL's 212SE, and get 2 if you can afford them. Stereo subs rock!
If anything you are going to have a challenge to tame the 60Hz resonance peak of +7dB in the bass. A sub may be the least of your problems.
