OK, did some thinking and... I love the look of three woofer towers. Sadly, with mainstream driver selection that means we need big swinging dingus king kong super arc welder amps to power them. I am fairly certain my Theta will drive a nominal ~2.7 ohm design - but most bread and butter amps will take a shit when asked to power through that.
So, that being said - does anyone have any interest in a group buy for 16 ohm woofers? I have done some legwork previously on MoQ for Dayton Audio in the past, and I imagine most suppliers will have similar requirements. For sake of argument, let's assume Qty 100 is the point at which we can expect to have drivers with custom coil windings etc. However, each vendor is probably going to impose different requirements and limitations.
Here are some of the drivers I think would be great in a 16 ohm version:
1. Eclipse W6520R
2. Dayton DC160
3. Dayton DA215
4. MCM 55-2669
5. Tang Band W6-1139SIF
Those are just five drivers that popped into mind, and I'll explain my selection process a bit.
The Eclipse is really close to being a world-class driver at a seriously competitive price point. I found it to have a very satisfying bass tonality and it works well in a 2-way as well as a 3-way. It is, as evidenced by several DIY event incidents, displacement limited in a single driver mode and currently there are no options other than the 4 ohm model making a dual woofer setup kind of moot if the builder does not possess a high current amp to drive past the 8 ohm impedance.
The DC160 is also severely output limited due to limited Xmax, but offers really good extension in a small footprint and a nice price point.
The DA215 is an 8" woofer that, while not playing particularly low, will work nice in a smallish cabinet
The MCM 55-2669 is a beast of a 5-1/4" and I was unable to make it sound ugly during excursion testing - in fact, the surround was probably the limiting factor. It is also very clean through the lower midrange, and the anodizing on the cone is a beautiful, nearly pearlescent appearance.
The Tang Band, well who wouldn't want a triple driver tower with these as the anchor? Holy crap.
I will be willing to take point on this project if we can drum up enough interest. If MoQ is 100, that would be 17 guys committing to six drivers each, or 13 guys committing to eight drivers each. I think that is a reasonable expectation.
Of course, I am open to other driver options, as well.
I have a signature.
