Well, I?m sold, the A15-8A can be a damn good speaker with a few minor tweaks. Adjusting the Bass tuning paid huge dividends. I recommend that anyone using them experiment with that. I used 3? expandable plumbing plugs to close off two vents in each speaker and the circa max flat alignment is light-years ahead of the stock configuration in a home setting. I have yet to experiment with lower tunings but re-tuning them is the way to go.

I have also started messing around with the HP section of the crossover. I replaced or bypassed the electrolitics and increased the value of the 5 ohm resistor to 7.5 (BTW, there is an error in the schematic I posted earlier. The 8uF shown should read 6uF) Anyway, 7.5 ohms may be a tad too much. The weekend plans are to play with that value to arrive at the best balance.

I?ll start a new thread about how to start fixing them up when I am done with initial tweaking. These speakers deserve more attention than they typically get.
