Post Subject: Mutant Ninja BassZilla sightingPosted by Paul S on: 9/27/2008
Looks like I'm back into this again, since, all of a sudden, out of nowhere, Yoshi up and sent me his "neutered" Reps 1 drivers (he surgically removed the whizzers).
I started turning my existing Basszilla components and these guys together like a Rubicks Cube, and I got some ideas.
One "problem" of the BassZillas is insufficient headroom for large scale works with my ML2s. And I just realized, for the first time, that the 15" Audax suffers a 3rd order low-pass network. Hell, if I'd paid attention, that would have been changed to 2nd order a long time ago, to bring up the weight downstairs.
So, I was thinking I could just add the Reps to the same open baffle and gain over 3 dB, and then I remembered the notch filters and Zobel network that knock back the Lowthers' whizzers and it occurred to me that with the specific gain from the neutered Reps I could also lose the notch filters and Zobel networks and just bring up the LF with more efficient drivers.
This means that the neutered Reps would be on top, then the Audaphon JP2 naked ribbons, then the Lowther DX4s, with more efficient LF drivers in the bins below. the Reps and Lowther would share a 2nd order 200 Hz high-pass. The LF would have a 2nd order low-pass. The JP2s would still use a 2nd order 10k Hz high-pass.
This should bump efficiency to better than 100 dB.
Then I thought that the baffle should be taller, and I might have to change the BR boxes...
Then I thought, maybe I should sell the BassZillas to a sane person before I ruin them, recoup some of my time to finance this latest madness.
My head is spinning!
A splash of cold water, please!
