what could possibly go wrong, right?

So I just purchased a pair of Tang Band W8-1808 full range driver and started thinking about what I could do with them.

Currently I have a few pairs of unity / synergy horns (300-20k hz) together with some simple and plain open baffle bass speakers. Ofcourse not the best combo since the horns have a very high efficiency and the bass does not.

I like the open baffle / baffle less sound so I want to go all the way with that for this new project and because my new work space (which will also be the listening room) is way smaller than first, I want some smaller speakers.

I am really fond of speakers like the Kyron Audio Kronos or the ones from Reflector Audio.

I want to use my bass drivers that I already have since I like how they sound and perform, these are FaitalPRO 15pr-400. I made a design where both drivers are as close together as possible, thinking of a crossover around 120hz or so to give the full rangers some relief at the bottom end.

BUT now the BIG question, what will happen with this set up? I really dig the look and everything, but will the 15" movement closely behind the full range driver cause distortion? It is firing straight into it, ofcourse the full ranger will move approx. the same but has a cutoff where the FaitalPRO steps in.

Total disaster?? or will this be ok to try?

The frame connecting the two will be laser cut from 5mm stainless steel. As for the legs I have to figure out a nice way that is at a reasonable price...

Let's say you can do anything imaginable in DSP. What would happen if you mixed in a little bit of the woofer signal out of phase into the FR - just enough to cancel whatever air-coupled "push" it's going to get from the woof, being in that position?

Flip the phase of the FR and run it FR? With a little high pass at whatever frequency the woof-coupling is no longer efficient? So what if the tympany doesnt make a wideband rarefaction? The design and stand looks cool!
 
Sometimes it would be positive and sometimes negative....

Try this arrangement: Woofer facing floor, magnet facing up, separated from the floor by a suitable 42mm gap to create a 'slot loading' and then FR above it at ear height mounted to the woofer basket on your choice of pole? Good bass, good stability...?

I'd rather try to make this one work first actually 🙂
 
Not only will low frequencies move the mid cone, which is bad, no matter how you look at it, but you will have another problem, just like in your other speakers, mismatch efficiencies, and even if you go active, woofer will run out of steam, and will bottom out due to cancellation...long sentence, sorry

I have seen speaker somewhere, where mid/tweet horn is in the middle, and four woofers open baffle are around
Can't find it right now

I think you mean the one I post underneath.

The system should not be able to play extremely loud, but what I not understand, both of the speakers are baffle-less, the fr is 93db and the bass speaker 99db so that is a mismatch in advantage of the sub right?

Since I really like the design I am thinking of just trying it and see where it goes...
