Anyone have anything similar to the converter

Maybe I should explain more clearly 

I have designed a passive network (converter) to work with the Anthony Gallo 3.0 3.1 3.5s  

It’s to engage the second voice coil or as marked on the speaker (sub in)

Originally you need Anthony Gallo SA amps and speaker wire and interconnects or an external crossover and amplifier and speaker wire and interconnects 

The unit that I have designed all that is eliminated ant it blends amazingly well with the full range and extends down to about 22 hz

The unit connects to the speaker in terminals on the speaker and then connects to the sub in

just wondering if anyone out there has a similar design or if people would like it to come to market 

Are there any Anthony Gallo speaker owners who maybe interested in the unit or have any additional questions?

Are there many Anthony Gallo speaker owners here on the forum?

Hi. I have Gallo 3.5s and might be interested. What have you got?

Sorry for the late reply, had some other matters in life that need attention.

what I designed is a unit that will engage the second voice without the need for a external crossover or Gallo amp. eliminating extra speakers wires and interconnects.

The low frequency range will drop to about 22 hz blending seamlessly with the overall speaker. The speaker is not physically altered in any way,The unit will have 4 wires about a foot long one set L and R for the speaker terminals and second set L and R for the sub in.

The unit itself physical size will vary from about 6 inches x 8 inches , or 8 inches x 8 inches weighing about 1to 4 pounds. 

As for my 3.5 s I totally redone the crossover with SOA capacitors and inductors and total rewire but that is costly ….but for me it’s worth every penny.. I have owned the the top Gallo 5ls and I can honestly say the 3.5s upgrade will compete with any 40,000 speakers
