I see, but you have identical subs I presume almost equidistant to the MLP.
Yup. They are in old fashioned walnut floor enclosures that were my primary
speakers long ago.
The woofers are mated with University horn loaded mid ranges and dome tweeters, also antiques. The reason for dual voice
coils back when was mechanical mixing of stereo channels. They are useful now in that I can use one VC for the sub-bass
and the other as part of the surround speakers, all in the same boxes. With the adjustable cross-overs*, I just turned
down the higher drivers to balance with the diminished bass response.
You just have to be sure they are smoothly integrated with the rest of the
speakers.
I did. Now, as the hearing in my right ear diminishes, I care a lot less about
such subtlety.
In my situation with very dissimilar subs at vastly different distances to the
MLP, clearly need to look at the histogram when raising the shadows.
Old fashion and new fashion sub, Mike
You need one of those monsters such as I just described. Make the walls of the
room radiators. ;-)
