I've done some MLTL, TQWT designs for others, so how big, tall can you tolerate?
GM
Just how large would you make it for a "no-compromise" (I know - there always are, but still...) reflex or TQWT?

I made exactly the same model as this address.
2A3 Maniac: Hochwirkungsgradlautsprecher: Offenes Gehäuse mit Seas FA22RCZ - der Bau
I used the 9710. The sound is very good, detailed, beautiful with good bass. For jazz and acoustic music.
Very easy to build.
I often alternate between this model and my old Bozak.

i build a TQWT with the 9710/M8 as driver and i just love it and it is just 26.4 (cm) wide.
Hi Xerxes,
Your design is IMO the way to go,way better than the suggested 'German' box proposed here-above:
The design is IMO a Lemon Design...
Luckily the opinion what's an acceptable FR is very varied but if ignoring to present an acoustic load in the vicinity of fs is a method I never have encountered before..
I've used 9710M in more than 50 build since 1968 and all were survivors ...over time.

dimensions etc.
Well i wrote that i would sent a PM but maybe there are more people who want something like this. so in the attachment there is a quick drawing i made just now.
I filled the bottom with fine sand for stability and all the sides (except the baffle backside) with under carpet. There is no filter or BSC.
all the panels except the baffle are 22mm MDF the front is 24mm (or 2x12mm) plywood.
but if you are limited with space you could build a small Briggs cabinet (see attachment) this is simple, small and sounds great.

Well, for a T/S max flat alignment tuned to ~35 Hz, a MLTL is around 60" high and ~18" square or ~8.733 ft^3 net.
A TQWT is similar sized, just shaped differently.

Thanks GM!
My "accidental MLTL" estimation is pretty much in line with this. Such a box might put out some pretty good bass, though GD may be about as high as tolerable (I don't know what my threshold is here though). I do not own my pair of 9710 anymore, but still keep an interest in these special drivers.
