Sealed Single 15"

Sounds like a nice recipe for some old school pant flapping tone. bagend makes a sealed 1x15 or at least theres a model that lets you go from ported to sealed.
Been there, done that for jazz band. It's called a 30-plus-year-old Polytone MiniBrute III. Lower mids whang from insufficient cabinet volume. Will be clear on the bottom, but will roll off, with not enough cajones for a lot of folks.
Sealed cabs are good for midrange and some upper bass drivers, but by their design won't extend the low frequency response. I just got a Carvin MB-12. Same in a sealed 12, plus 6.5 inch midrange & tweeter. It does roll off in the bass some. But...that is the reason I got it: to replace my dying Polytone. I want the low end to roll off because I use it to amplify DB in jazz band. If I need bottom reinforcment, or want to run it with my custom P-style bass, I have a 1X15 ported that has the bottom that I can add to it. Or, I can use my SWR Triad instead.

I tried the sealed 15" route (EVM-15B II) w/my upright bass and it just didn't quite swing for me (playing jazz and other acoustic applications), so I ran the driver's T/S on WinISD and ported the cab, much clearer and w/o fartage using a blackface Showman head. At 85 watts it isn't going to overdrive pretty much any 15" bass driver built after the mid/late 70s. YMMV etc.....
I have 2 Ampeg Portaflex 115 cabs on order. They are sealed with a tweeter. Paired with a PF500 amp, I'm hoping for a little classic B15 tone out them. But I most likely won't know for a couple more weeks...
Many years ago (1967), I faithfully copied a blonde single showman, and used a D140. It sucked. I was too young to understand the importance of the showmans tone ring. I later swapped a pair of D120's in it (still sealed), and it blew the D140 away.
