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
