Revel GEM or Wilson Cub 2 ?

First of all thanks to everybody for the helpful advices!

I just got an offer for an Revel Ultima System including two (!) Sub-15 and the LE-1 and the Gems. According to German (retail) prices, the asking price seems to be very fair. It is about 5500 EURO. Retail prices in Germany should have been about 35000 Euro...

I know about the importance of listening to any speaker by oneself but since the seller is 500 Km away from me, I would like to ask the Audiogon members first:

1.) What do you think of the combination Gem/LE-1/2 Sub-15? Would it be an upgrade compared to my Wilson Cubs? Will 2 Sub-15 be too much for my 20 m² room?
2.) Would you prefer the combination of the Gems with the B-15 (integrated amplifier, many possibilities to adjust)? It should be possible to get the Gems with the B-15 for 5000€.
3.)I don´t exactly know, if the crossover in the LE-1 has just a (fixed) high pass filter (80 Hz) to play with the Gems or if it can be adjusted?

Thank you,

Benedikt

"I was quite surprised, how good the Cub 1 performed in that area and need a speaker that can deliver at least 50 hz at higher volumes."

Why 50 hz at high volumes? What are you purposes/uses/expectations, for the speakers? Are you planning home theater? Or just 2 channel stereo? And, if a big room, why smaller monitors? I'm confused here. If Home theater, you're DEFINITELY going to cross em over much higher anyway! Or at least you SHOULD.

I´m sorry for confusing you. My room has only 20m². 2 channel stereo only!

I don´t need a speaker being capable of playing at high volumes but it should offer full range sound at low/medium to slightly higher volumes.

Er, um, Ok, so why smaller speakers? I'm confused.
Whatever, anyway, I think the Cubs play lower, yes, and they're probably more sensitive and dynamic as well, all things equal. However, the Gems are more flexible a bit. Wilson recommends keeping Cubs on "those stands". I like more flexibility, depending. Still, you're in the same league with these. I'd still go large speakers though.

The LE1 is not a reliable sub amp according to someone that used to work at Revel. I would go with the B15 subs. I had also considered the LE1 but decided to go with the B15 which has worked well.
