Dedicated mid/ mid-bass Cabinet Design

[TheFluffyDog]

So for a lot of the veterans here, I'm sure you've had this argument 1,000,000 times.

"bass reflex, sealed, TL, whats the best etc."

But I have a more specific questions. I have a pair of subs that do just fine from around 300-22hz. I also have digital crossovers and DSP. So in my newest build I will be using 4 different drivers and 4 different bands. One of these bands will be in a region between 200hz-1200hz. Now in my experience, driver characteristics dominate the SPL curves and distortion profiles in this region, but i had an idea.

What if i use a high compliance driver and seal it in a box tuned to have a resonance and f3 1.5-2 octaves away from the crossover point? Most cabinet design aims to control the tonality, gain, and extension in the region near or below Fs, but what if i wasn't even trying to go that low. Is it possible to use the air spring effect to create a linear restoring force at higher frequencies? And does it even matter? I could not hunt down anything on the subject since everytime i look at cabinet design data it focuses on the characteristics of low bass.

Not really sure but I suspect that at higher frequencies the driver response is no longer is pistonic so the air spring effect won't change the response. You can post your question on the speaker builder forum at parts-express.com
