JW Sound

I get asked quite a bit what subwoofer I recommend pairing with JMODs, so I'm sharing 3 designs that I am happy to recommend, each being fairly similar in terms of how they sound being all 6th order bandpass (/bandpasshorn) designs offering deep extension and a very heavyweight, articulate "hifi" sound.

Ricci's SKHORN
> Why I like it: my personal favorite as being the best overall sounding of the 3. The adjustable port blocks mean you can quickly go from a general use subwoofer with a 31Hz tuning to an infrabass sub with an extremely low 18Hz tuning. The sound is intense and heavyweight, but still maintains a high degree of control and precision, especially noticeable in triplets and in exhibiting clear kick/bassline separation.

Ricci's SKRAM
> Why I like it: it's far more portable than the SKHORN and keeps the adjustable port tuning feature. I think the sound can be described as being slightly more engaging/exciting, or "forward" than the other 2 options, so worth considering depending on subjective preference of where you want the subs to sit in the mix.

B&C S218BP
> Why I like it: high power density in an easy to move package. The dual-opposed driver arrangement with the magnets placed near the vent keeps the box stable and drivers cool. The sound is very natural and articulate and easy to integrate with tops without overshadowing them. I'll have more thoughts I'm sure after I've built and tested more.

Are there other designs that would work well? Of course; these are just 3 designs that I've personally field tested and validated.

I've uploaded both the SKRAM and SKHORN designs to my website with relevant drawings, CAD files, and the original databass forum posts with permission from Josh. The S218BP design can be downloaded from the "suggested designs" page of B&C's website.

WIP. Something I've wanted to experiment with for a while, but needed the right timing and set of circumstances to see it through.

Not shown is the hours upon hours of simulations and setting up workflows to optimize the horn shapes and coverage patterns. It's a bit of new territory, but the idea is that when executed properly, destructive MF/HF interference can be minimized to an acceptable level, while constructive summing occurs in the midbass region.
