I can understand the reasoning for trying the 99’s and the wood finish. Piano black is a pain to maintain. I hand polish my subs with automotive and piano polishes.
Yes, certain material is overwhelming with my 31’s also. However I like that there is a digital setup with these subs, and they can be adjusted in 1Hz increments by remote. Negative levels actually produce a lot of output from the 31 and much more than I anticipated. The reference subs have a parametric equalizer that I’ll play around with soon.
Luckily my dealer informed me of the price increase late July. I ordered then, and the second came from TMR. The Upscale Audio email I received this morning revealed a 20% increase for the 31 while the rest is 10%.
Hope it all goes well in your setup.
