This particular unit goes from -6 to -16.5dB in 0.5dB steps which is perfect for padding that horn down to the bass. The "coarse" steps are 1dB and the toggle allows for a 0.5dB trim.
Of course it resides on a permalloy core and allows the end user to select the desired impedance presented to the crossover by selecting the shunt resistor.
Wiring is simple with the same 3 connections as an L-pad. More info to come!

That is hot!
ReplyDeleteI need that
ReplyDeleteNICE
ReplyDeleteGotta have me some of that!
ReplyDeleteGreat idea, very cool
ReplyDeleteLook forward to more info.
ReplyDeleteI should try mine again and put it into the crossover.

But why permalloy? The saturation level is much less than in a good steel, and it's a headroom first...
ReplyDeletesaturation and headroom are not an issue but low level signal behavior is and for that permalloy is King!
DeleteHi all-wanted to say that I'm the owner these. I just swapped out the L-pad and they are so good it is silly. VS an l-pad there is much less haze, more bloom around treble and strangely, more coherence (?) like a more integrated sound--can't explain the last bit, but its almost like the XO is doing its job better. If you are even remotely close to thinking about this, contact Dave/Jeffrey asap. Killer upgrade.
ReplyDeleteOh Man, I want some!
ReplyDeleteAwesome value for money upgrade. I've had mine for a week now (the simple version, just bare autoformersw ith flying leads) and at first just hooked the crossovers up to a signalgenerator and scope to find a tap to set the level where it was before and calculated a shunt resistor and hoked them up and listened. Yeah baby, "better" highs, "better" bass, more life, more music. Today I actually measured the speakers and played around with shunt R and taps ending up not far from the original settings. The autoformers really clean up impulse response.
