American Bass XFL's in a Sealed Enclosure??

[FadedSpy 10+ year member]

I've currently got two AB XFL 1244's in a 4^ft box tuned to 34hz. They're being run off of a VFL 150.1 and boy are they nasty! Problem is that I've got no trunk space now so I would like to build a smaller "Sealed" box. I know i won't be as loud and I'm ok with that. They are more than enough as it is, maybe it'll tone them down a bit. I listen to a lot of Alternative and Rock that doesn't sound all that great with the current box.

I know that AB recommends only putting them in vented enclosures so they're aren't any specs for a sealed box so I'm not sure if A) They'll even sound good in a Sealed Box or B) If there is an exact size of Sealed box to make them sound Optimal. I was thinking about 1.5^ft per chamber Sealed but before I go off and spend money building a box I would like to know what you guys think?

I could actually build another vented box with more precise measurements and gain about 8" in my trunk which would help but fIf I can get better sound quality from a sealed box then I might go that route.

Wacha think?

I've seen them in 4th order bandpass configurations so sealed should technically work.

They like about 1.5 each sealed...With enough power they should sound good ...

Cool. Thanks for the feedback

Do the each need their own chamber or can they share the same chamber? Does it matter?

Put them in 2.5cubes common chamber and they will be fine if you do separate chambers use 3cubes. Common chamber boxes can be smaller for some reason.

Or consider selling or trading them that's a little more sealed friendly, such as some of the FI subs, or perhaps IA Flatlynes.

I built a box that's about 2.75 cubes common chamber just to test them in. I plan on building a more trunk space friendly box later on but I wanted to see how these performed in a sealed enclosure. Next box will be 5 cubes @ 35hz If I build it just right I should be able to keep 1/2 of my trunk free. I will have to do it using Aero Ports or PVC which I've never done before so I'm not sure how to even calculate all of that in Torres like I have done in the past using my Slot Port Enclosures
