soliloquy 5.3 or 5.0 w/sub?

Not with these models exactly, but a very similar set from ProAc (Studio 150 small D'Appolito floorstanders vs Tablette monitors). I liked the floorstanders better than trying to integrate the sub. However, I don't listen to music with much in the mix below 30Hz, and I didn't have as much bass management (control) flexibility nor sub placement flexibility as you may have. How big is the room? If it is medium>large, you may want a different sub anyway to produce enough output for decent in-room LF for HT.

I own the 5.3s and if you have at least a medium sized room and flexibility to place the speakers at least 3-4 ft from the back wall you might want to go that route to avoid dealing with a sub. Given a big enough room and proper placement they can really put a performance in your room.

If your room is on the small side and you need to keep the speakers within a foot or two of the rear wall you might have better luck with the sub/sat setup that will give you the flexibility to place and adjust the sub so it doesn't overload your room. The 5.3s really need room to breathe to be at their best(in my opinion) and they can get congested and boomy if they don't get the room they need. I'm actually thinking of selling my 5.3s(to trade up to 6.2s), so please feel free to email me if you think you might be interested. Hope this helped and best of luck.

Hi Tim, are you still selling your 5.3's?

LoL, 20 years later?  Lets hope not...

Never hurts to ask.  Yeah, I sold my 5.3s shortly after my prior post and bought the 6.2s that I’m still thoroughly enjoying and will probably never sell.  I noticed some 5.3s show up from time to time on various websites, so if you check HiFishark.com you might find a pair before too long.  If you don’t find any and don’t want to wait, I find the Joseph Audio RM25s offer many of the same characteristics and might give you another viable option.  Best of luck in your search. 

Actually there’s a pair on eBay and another on US AudioMart now in case you’re interested. 

The truth is subs work best with large speakers. The power band of the hand off from large powerful subs is never right to small speakers imo. I use two subs for my two channel for what it is worth. 
I will go one step farther and say most large speakers need subs too. 

Wow, that’s a great deal.  Enjoy!
