the ancient urge to build a dual-woofer three-way

Here's another even more happy thing you can't do any other way:

You don't even want to imagine executing a five pole Butterworth bandpass in passive, especially at these frequencies. You'd have capacitors the size of cantaloupes and inductors the size of bundt cakes. Plus, again, it would be pointless because it would suck.

So, what's the reason for wanting two bands in the bass? There's really no such thing as a driver that is both competent at 20Hz and can articulate at 200Hz. And vice versa. Heretofore there hasn't been a solution so, again, a lot of splitting of babies.....never has anyone totally nailed it in the bass. The state of the art has been just sorta OK.

This solution is our Trademark: Dual Band Bass. It solves the problem elegantly in a single stroke. This does not sound like any bass system you've ever heard. It kinda takes your breath away. So far, this has proven a remarkably effective sales tool. Guys who experience it immediately shift their expectations of low frequency performance, spoiled, they find a way to buy it. Ha, ha, ha....I know it's bad....but I do it anyway :-)

That's incredible.
I just never imagined that would be doable . This is speaker designer dream come true stuff.
 
Yeah, last week I had a long conversation with a fellow intent on persuading me to build some conventional speakers. Not the first time for that chat and, as with those before, he hasn't heard my current work. I understand, we all love conventional audio and the few dsp/powered things out there are aimed low. So it's easy to wave the new ideas away, and stick with the old way.

So I explained that I'm at a stage in life when I will do no work other than my best.

Being able to execute ideas like this really is a dream. Slaying dragons that have dogged us for decades. So, conventional? Aaahhhh......no thanks. :-)
 
'been quiet about this for a while but it has come along nicely. After a few months of living with them we're finding them consistently compelling. Just me, I'm big on emotional connection - which often wains over time as the faults emerge. Not this time, this thing is overwhelming.

Looking at the physical stature, we keep thinking "Ibis":

Crusher, Subibis, Ibis:

The only problem is: we've shown 'em twice, sold 'em twice.......well sort of......each guy said his wife wouldn't go for the separate bass column, so, for them, we're building this:

Making two chassis will keep the weight manageable. Two NCore Fusion plates: 100x500x500W, 2x500W.

There is a large millwork job clogging up the shop for the next month or so, then we'll start the builds and post pics.

There's also a petite variant in the works for smaller spaces with max res in mind.

This is what I want! But also... my room is only about 12.5'x16.5' So I'm very curious about the Baby Nightingale as well.
