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

I’m with @mr_m on the preference for a sub or two, regardless almost of whatever main-speakers may be used. And I wouldn’t skimp on the size of the sub(s) either as I feel you really can’t overdo capacity, but any sub capacity can be dialed wrongly. The bigger the displacement area the less cone movement is required, and the more effortless and enveloping the overall sound will potentially be. The bigger issue, apart from proper implementation with the mains, may also concern how to high-pass the main speakers the best way possible (if one even chooses to high-pass them to begin with), so not to let the filtering here impede on the qualities of theirs.

I’ve only heard the smaller sibling, the 803D3’s, and for what they are (my preference in "sound-type" lies elsewhere) they’re rather extraordinary. I gather the 802D3’s could add to this sensation and be very capable as standalones as well, but a pair of large, quality subs (preferably sealed) - with proper care invested in their implementation - could really lift the presentation substantially, and make for an enveloping, versatile, scaled and dynamic sound. A pair of Funk Audio 18.0C’s, for example, would cost you from close to $5,500, but would be very worthwhile. Myself I use SVS SB16-Ultra’s, and a pair of those would set you back $3,800, but they’re massively capable as well (the SVS SB4000’s would also fit the bill here).

In light of the investments thrown about for cables and other accessories - (de)coupling, room treatments and what not - subwoofers and their cost could be the lesser issue in light of their sonic impact, certainly if one were to ease back on the expense of named accessories instead, effectively totaling for a macro-change and -improvement of an altogether different magnitude. Spent your money where it really matters and involves physics; conversely accessories can set you back with crazy amounts of money that oftentimes only involves change (if they’re not detrimental) rather than betterment.

Do you think the 60.8 will do justice to the speaker?

They will very much so, BUT!!! to a certain level. Depends on what sort of music the owner listens to, and how loud.

Nice room... after seeing it, I think the low end will be more than adequate in your space - especially after seeing where the left speaker is placed in the corner.  You will likely have tremendous bass build up there.

If you’re not listening extremely loud with extremely heavy bass content, Your amplifiers will be just fine.  Could you get more from the 802’s with more power? ... absolutely!  But I think you’ll be thrilled.  Some tasteful room treatments and proper bass trapping would be of more benefit than anything else I’d venture to guess.

I have three of the 802 d3s across the front of my listening/theater room. They sound great. I also have a DB1 subwoofer that I ordered at the same time. Honestly, I am still fooling around with the DB1 settings and also the lower frequency settings on the MX160 to get punch from the sub. But as to your question, the 802s sound really great even without a sub. I have played them both ways, with and without subs and I can tell you I here subtle differences while playing them. I listen to many different types of music and movies through them and they do sound great without a sub. Everything from dave mathews to star wars has been played through them. I would just keep them from the back wall about a foot or so. Set them up and see for yourself if you need a sub.

So when’s the speaker coming Bryce?
