New Magneplanar Bass Panel DWM

I want to hook 2 bass panels to nice studio book shelf speakers.    Worth a try  ?  Bad idea ? I know there not subs.   But should go lower.  Yes?

I had one with my 3.7i's.  Do not expect them to sound anything close to a sub because they don't.

twoch---Lower, no. The DWM doesn’t play lower than the MG3.7, or even the 1.7. But it does provide more output above the frequency at which Maggies start rolling off---40-45Hz. It’s NOT a sub, it’s a bass driver.

I live in a small house with a small listening area sectioned off the circular shape of the floor in my round house. I recently connected Magnepan 0.7s to my system. The room is not big enough for larger speakers, even if I could afford them. According to the A weighted sound pressure meter at the listening position, the reading I looked up for the difference between 1 kHz and 100 kHz on a test CD was right withing a fraction of a decibel. Since the DWM works between 40 and 200 Hz, this seems to mean I would not benefit from adding a DWM. Below the 45 Hz I have a pair of subwoofers. In a bigger room I might need the bass panel, but for now, the 0.7s sound so clear and transparent I don't think I want to change anything.
