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

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.

I don't know what the world is coming to.  Audiophile types are starting to recognize the merit of active designs?  I bought the Infinity Intermezzo 2.6's back in 2001.  They were half active, Stereophile and TAS both loved them but they didn't sell.  Audio Advisor blew them out for about half price not long after they came out.  I regret selling them as they were truly excellent.

Now we're hearing people who not only accept active speakers but speakers with digital conversion built in, digital crossovers, etc.  I hope it lasts.  It will bring the cost of high quality audio way down if it gets popular.  

@jon_5912 -- I would submit that in case of the KEF LS50 wireless, what helped them was the fact that the passive version was already a critical success. KEF just made it better.

To be honest, if I hadn't heard so much about the passive version, I would have never tried the active version. So at least for me, it was not some newfound appreciation for active monitors that made me buy them. It was the fact that I was already planning to buy the passive version, but the perceived lack of bass was making that decision difficult. The active version solved that problem.

As an example, I had thought about purchasing the Dynaudio Xeo 2 but there was no similarly shared pedigree with another base Dynaudio model as critically acclaimed as the passive LS50s. So I stayed on the sidelines at that time.
