I'm new here, so please correct me if this belongs in the software tools or live sound areas... I'm posting here because a ported guitar or bass cabinet is essentially a full-range speaker in that it's got one driver that you're trying to get the most of. It's just that the sonic end goal for a guitar cabinet is different from the Hi-Fi goal.
There are a lot of speaker cabinet calculators out there, but the ones I've seen all seem to assume you're trying to build a system for Hi-Fi. They don't seem flexible enough. Any recommendations for cabinet calculators (preferably web-based) that might offer enough flexibility for this application?
FWIW, I'm hoping to use a Jensen Mod5-30 driver that I happen to have on-hand.

This should be in the M&I forum.
The answer is you don't need a separate enclosure calculator for M&I speakers; you merely need to know HOW to use them.
M&I speakers are usually NOT tuned to be flat. For an open back guitar combo speaker, no calculation needed. For closed speakers like a 2x12 or 4x12, most choose to just build to vintage enclosure dimensions. A 4x12 typically has a bass bump and a mid dip.
Ported bass single driver speakers are usually tuned to a bass boost, and Fc in 50Hz or higher range.

This driver has a high enough Qts, low enough Vas for a small open back box, so not critical and with a 125 Hz, not much of a mid-bass one at that.
Noted. I will still follow up on your comments here, and the things that may sill be on-topic. Then I'll take it to the other sub-forum.
That's why I was asking for a suggestions for ones that are flexible enough. The ones I'd seen had baked-in assumptions about the goal.
Exactly the kind of thing I meant about "the sonic end goal" being is different.
My house is already littered with open-back combos, some homemade; others bought. Not going to do that. 🙄
I don't copy vintage designs with my electronics. Not going to start it with a speaker...
Makes perfect sense.
Are you recommending against a tuned-port enclosure, or just saying a small open-back enclosure is the easiest design to use this driver?
Thanks.
This Jensen driver has a very high qts that suggest open back when i look at the specs. Sealed may work also, but ported not. Ported best have a qts between 0.25 and 0.45 and an EBP (fs/qes) of +50. EBP looks right, but QTS absolute not. It will be a one not bass response with that high qts. You can model them in any software to see what i mean (winisd is the easiest to learn). But to make it short, this driver is made for open back, not for a closed cabinet. Ported is picky about this, sealed much less. So if you want to make a cabinet that is not open back with this driver, use sealed.
Right, start open back and if you want to try vented, then block off half the back and if you like where it's headed performance wise, try a 1/4 opening.
Personally, back in the mid '60s when I was fiddling with hollow body electrics, I had zero luck with improving on their partially blocked recommended amps short of plugging them into my Altec A7-500 small cinema horn system like some bands were starting to use at outdoor concerts, then they really came alive.
Regardless, try a ~8 L/0.282 ft^3 and let us know how it sounds.
