Dayton Audio UM18-22?

Hi, i want to upgrade my 2.1 setup in the basement. I have a pair of diysg tempest 12 and a jbl 2242 in a ported box. My electronics are two crown xls1502 and a mini dsp 2x4 with dirac. I was thinking about replacing the jbl with a Dayton Audio UM18-22. But instead of ported i would make it sealed, the box i have is about 8,8cu f. 250liters. I mainly listen to music. Is this a good idea or should i go for something else?

A VBSS sub with the 31Hz tune may better, and cheaper for pure music.

I used a couple sealed ultimax's in 4cuft boxes for music only, they were solid. Bigger boxes would only help IMO.

I think this will work fine. May need to add a high pass from the crown depending on music and listening levels. At over 8 cft, you could add two UM18's and forgo the high pass.

Agreed. You and your wallet will be happier with VBSS tuned to about 31 hz. My UM18s didn't come close to VBSS for music. Built for different things.

I checked the vbss thread here on avs, that looked intresting, but isnt that pretty much what i got? One concern i got is that a low sensitivity sub wouldnt keep up with my mains. I run the jbl 2242 at 60% on the crown 1502 in bridge mode, and mains at 75%. That gives me a slightly bas heavy curve.

A Dayton Audio 465s-8 is around 180$ and the um18-22 400$ here in sweden. Mayby i should build two 465s in vbss boxes and run them bridged in parallel on the crown. Only placement i could fit is diagonal, one in the left front and the other in the right back. How does this sound to all of you. Very thankfull for all comments! This saves me money and wood dust
