New pair of DIY VOTT / A7-800 Crossovers almost done

Posted by drlowmu (M) on March 25, 2016 at 19:11:21

12 dB / Butterworth, 800 HZ., 16 Ohms.

One crossover is done, the other one gets done Sunday, Easter.

Also desperately need to replace my Type 45 DC amp's speaker jacks, hopefully this Sunday evening, with something much better ( Cardas Silver- Rhodium ).

Wow, I will soon FINALLY get to hear my own finished A7-800 implementation. It should be FUN to hear.

I determined that 12 to 14 pounds of mass-loading was the ideal amount for my crossover, ( a "sweet spot" ensued, richer harmonics, more dynamics, higher SPL ) hence the added on top plate, to hold incrementally-added bricks.

I had to SUBTRACT an equal amount from the A7 enclosure's mass loading, easy to do with these concrete tiles.

Now, everything in my audio system is mass loaded, by ear.

My Type 45 amp is now up to SIX bricks, and it is delicious to hear. VERY focused sounding. So, I have discovered each audio component in a good high efficiency system has an an optimum mass load !! Amazing stuff.
