Magnepan vs B&W: Same specs, different bass?

Thanks for the input guys, sounds like everyone thinks with the similar specs they should perform similarly.  I thought maybe conventional woofers with more throw might have more punch than electrostatics or some other explanation like that.

I'll try moving the Maggie's around the room a bit to see if I can get more bass out of them, but it's such a big difference I doubt I'll be able to.  I'll try to take some measurements this weekend and post them.

I'm using a Levinson 433 amp rated at 400wpc at 4 ohms which should have plenty of power, right?  =)

Also, "conventional" speakers sounds as though they have more bass if they have a rear port and postioned close to a corner - it reflects off the wall/corner.

My current speakers were quite good in a smaller room, but now they are in a larger room their bass has "normalized" and those lower frequencies that were present all the time are now only there when actually present in the music.

Last time I heard excellent sounding Maggie’s they were in a room with 4 ft behind them and around 5ft in from the side walls and 7 ft between them.

Hope you have a large enough room

Speaker specifications are meaningless. 

@markalarsen I think I'd agree, I moved the Maggie's all over the room and can't get near the amount of bass out of them...

Hey guys, I took some measurements today with a calibrated microphone and as suspected the Magnepan 3.7’s are not performing nearly as well as the B&W 803S’s below about 75 Hz. I pulled the Magnepans out about 4 feet from the rear wall hoping that it would help but didn’t make much of a difference.
