About to purchase the Kef LS50W speaker want opinions about set up....

New Hampshire, The store is Audio Video Therapy in Nashua. 

Update......ok so I recently downloaded Roon and streaming all my Flac files to the LS50, this system is so much fun to not only listen to, but to play with. I still can’t believe the about of bass it puts out. My question is what would be the least expensive way to improve the sound even more? All files are 44.1/16bit. What pieace of gear or DAC are others using with the kef’s?

@matt00 

Just buy a sub from Hsu, SVS ,.... and cross over with the speaker at 45 Hz. That will improve the sound a lot

I don't know much about subs but from what I've read  to get more base from 45Hz down you have to cross over at 90  Hz as that is where a it starts to dive with a speaker rated at 45 H ?
I hope I'm wrong .

I bought mine a few weeks ago. I haven't put 50+ hours on them and the dedicated stands are still on backorder. They are amazing as is, I can't imagine how much better they will be once I put them on stands (filled) and put a few more hours on them. Really satisfied with the purchase. They sound way better than my previous system which was a little over $8k.

I haven't felt a need for a separate sub yet, but maybe I don't know what I'm missing. If someone has tried a fast, musical sub with them, I'll be interested in your review.
