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

Hey everyone,

I recently acquired a set of Magnepan 3.7 speakers which are rated down to 35 Hz, and I've been comparing them to my B&W 803S speakers (also rated to 35 Hz).  While I enjoy the big sound and clarity of the Magnepans, the B&W's blow the Magnepans away in the bass department in an A-B comparison test.

I figured this would be the case, but I can't explain why there's such a big difference in bass when the speakers have the same specs.  Can anyone explain?

B&W 803S specs:
35Hz – 22kHz ±3dB

Magnepan 3.7 specs:
35Hz- 40 kHz

Thanks,
Chris

@cjwessing 

its all in the setup. For two years I struggled with setup of Maggie’s from the 1.7i’s to the 3.7l’s and then with the 20.7’s. I was able just a few months ago to dial them in and the bass is amazing. Sonically amazing! Follow the Limage methodology for placement and you will get the results you desire. Air, openness and deep hit you in the chest bass.

Those speakers seem awfully close to the walls, in my opinion.
Is there any way to move the chair backwards?

I agree with gdnrbob.

They definitely should come out from the from wall more. They should be out about 40% of the length of your room and about 6-9 inches from you side wall.

I just followed the setup instructions from the Cardas website, here are my room measurements:

Here's the Maggie's in their 'optimal' position, something tells me my wife won't allow this... =)

Here's the B&W's in a similar position:

Here's the measurement comparison:

Looks like moving the Maggie's definitely helped in the 40-80 Hz range, but now I've got a significant room mode around 100 Hz.  Also they still don't have the low end punch of the B&W's, maybe it's that sub-40 Hz performance of the B&W that I'm feeling?

They’re way too close together and did you move them out 40 percent of the overall length of your room?
