Perhaps someone knows the answer to my question. I have searched long and hard to no avail. I've also posted at diyaudio about a week ago.
I currently have a pair of Magnepan MMGs, and a pair of Dayton RS315HF woofers. Right now, the Maggies are powered by an SA-XR50 receiver. I would like to put the woofers in sealed boxes, which would serve as stands for the Maggies.
I have been considering retiring the SA-XR50 to the TV room, and buying a SA-XR55 for the stereo. The Panasonic SA-XR55 receiver has bi-amp capability, so I thought this would work well with the setup. I would use a passive crossover at about 150-200Hz, and I do not have a problem with the large crossover components that would be required. I have ready access to this sort of componentry. I would then ret
However, this leads to a different problem, which is that the woofer has considerably higher sensitivity than the Maggies. However, looking at the SA-XR55 manual (page 21), I see what looks like a HF/LF balance setting, which I think would allow me to set the relative output of the HF and LF channels.
Someone has confirmed that this is how it works, but does anyone have an idea of the adjustment range? Another possibility is to use a line frequency transformer as an autotransformer to knock down the woofer sensitivity, which should at least get me close. I already have some transformers that should get me within a db or so of the spec'ed sensitivity.
As an aside, the manual also shows that you can adjust the HF/LF relative delay.
I do know that there are a lot better things I could do with these drivers, but my audio hobby time is limited. Thanks for any help.

Maybe consider trying dipole woofers, first, before you seal 'em up? It'd be nice to preserve the dipole radiation especially if crossing at 150-200Hz...it's one of the MMG's best qualities, I think. Nowhere near the output of sealed, of course.
