I would recommend this...
-Run them with same polarity. If not, you'll get an unloading below Fs.
-I would also try a 2.5-way if you use 2 woofers. This will negate the distance between the woofers, and the lower woofer will not have to struggle to meet the widebander due to the distance they are separated. It just takes a largish I-core coil in series with the lower driver, and the L/driver series combo then in parallel to the other woofer, to facilitate the X.5 implementation.
Later,
Wolf

No problem, it is unusual.

I also have a Omni OmniDirectional - work in progress that uses an 8" woofer like your LX mini. I found the bass was insufficient and was considering a new Omni design but decided to just add a separate subwoofer (SonoTube). Its actually better as you can position it in the room to minimize room modes.

I bet you having god time with OmniDirectional project ...looks bloody god !
A bit jealous about those pipes you are using... i can`t get those in our tiny Denmark. I have to use real stuff like 3" heavy duty water pipe ( don't even let me start on a pricing ).
Omni directional design is a way to go with a speakers ,off course let not to forget about CBT Speakers .
Thinking about most impressive speaker designs and god execution of those it would be omni directional but not a boxy designs.
Just let us take Ohm Walsh , Duevel Sirius, B&O enter in a sound market when dinosaur has walked the earth, even they can`t came up with anything better as a last resort staying on a water surface , but with omnidirectional speaker design .
So we are on the right road DonVK !!

I'm intrigued by omni, I have dipoles which I like, I notice from your photos that the widebands are open back, are you getting dipole radiation from them?

I've never heard of them (RIPOL) previously so I had to look them up .

They look like a very interesting and compact design. It was described as a folded dipole. I was thinking of how to model it to predict its performance. A few articles described it as very good for music, but not punchy enough for Home Theatre. There were no measurements so that's speculation.

P.S. The sewer pipes are 4" PVC , are very common here, and cheap.

Dipole designs are beautiful as well ! To me dipole-bi pole-omnidirectional is like a wardrobe for the same person. Clothing different but the person is the same. All it is about execution.
About those widebands...yes that was an idea .

Yep RIPOL is a ride on a wilder side I guess and you absolutely right they are for listening music but not for opening doors and windows in a neighbours house.
Same links on RIPOL :
