Sorry for being just that lazy, But as a "semi professional singer" i can play notes higher in the males pitch and loudest as to a rock'n'roll demand, ut that for short excursions, as of testing some apparently good reverberating places, which stands guys such as Axel Rose on top of a magnitude of demi-gods really, cmon please, it is easier to ask here than to find anything people choose to come across I believe I am a single dogma chaser not a fool if anyone stands by please take a good time.! IO believe!, optimal, regards, bern.
Okay So Was I wondering. Dealing with handmade projects for spirals, w-Horns, reberberating places, reflecting wall optimal inclination, optimal real place parameters, I can't until now really tell unti now if a speaker, as a Dipole, can have a especially desgined box to take advatage of the sound emanating from BOTH sides of the speaker, as to say, curl the back propagation of the speaker as to come approximately in phase with the front side radiation of sound and sum up. That would garantee several decibels work as of with horn increases.

The cabinet has to be carefully designed so that the back signal comes around as much in phase as possible with the front signal.
The design usually makes it lift the bass.
If for some reason the front signal is more than 180 degrees out of phase the signal will subtract from rather than add to the sound.

Transmission line speakers are stuffed and ideally they completely ABSORB the back wave. And they do it very nicely.
Of course the purpose of a port in a bass reflex is to reverse the phase of the back-wave. A bass reflex does exactly what you request, but as Nigel points out, get a book and do the math or run it thru a simulator, or do enough math to get it in the ballpark then use a telescoping port.
Look into tapped horns, which are the most efficient configuration available. They do exactly what you ask, they use the radiation from both sides of the driver, with one face entering the folded horn exactly a wavelength down the horn. There are some trade-offs available between bandwidth and efficiency for you to tailor to taste.

Alright yeah a lot of people in here are posting pictures of their speakers opened both sides to the listener 
So there IS actually a way! Good for us! You guys know a very beaty example? Better try out of something hey!

I just have happened to come with an oversized box here, back in some experiments with bass, which possibily would render a very sharp response as with just a front horn adapted to chase on purpose. Here, take a look at it: https://soundforums.net/threads/8742-Oversized-box-524-Liters!
Look, this box has just holes in it, and that make ABSOLUTELY NO DIFFERENCE IN SPL even that size big.
Having a tapped horn in the working range of 200Hz-2kHz would be optimal for vocals, the rest of the frequencies could be implemented with conventional compression horns (the 2kHz - 13kHz range add's brightness to vocals and can not be dispensable).
I dunno, I am not much into that "go" for ridiculous large boxes. Lets slay much with Squawkers and rock their membrane out of them!
