Are American Bass XFL15s worth it?

[skaterboyjt97]

Id really like to do something like this. I laser cut and engraved a Panel for LEDs, and i sketched an idea what id like it to look like. Im probably not going to be able to a 4th order because i only have around 10 cubes total in the trunk.

how much trunk space do you have? don't try to shove 2 15s when you can only fit 2 12s appropriately.. make sure you have space for hte woofers to properly pressurize the cabin..

the XFLs have way to high a MMS.. not sure what they get from those inefficient designs. I could see if you had a 80mm coil with a superthick SPL cone but 311 grams is pretty high for 19mm xmax and 1k RMS.. each to his own.. shrugs

Right now, the dimensions of free space are 38 Width, 41.5 Length, and 18.5 Height. Id end up having to take out some of the carpet and spare tire room in the back to add more usable space.

can you get that box in the trunk? if you want to build two individual boxes and put them in that's cool but be far-warned that stuffing boxes/box in the trunk will hurt output..

Id try to keep height low as possible and face the woofers back and ports back.

could you fit a box 16hx36wx28d in the trunk? **** that is only 7.5 meassure and tell us the deepest you can get. you need at-least 32 deep

I actually came up with a compact 4th order design that will fit. 10.35 Cubes in the ported chamber, 2.19 cubes in the sealed. Port tuned to 34 Hz and its 8x12x13.88" . But i might try to even out the ratio a bit because it is a really peaky box at 34Hz. EDIT: The top is really sealed off, but a made it simpler to see the chamber.

holy ratio batman

 

[big scott]

whats that like 5 to 1 .

Close to it, id like to get the ratio down to 8cubes to 4 cubes. drop 2 cubes on the 10 and add 2 to the 2.

I dont think you know how to design a proper 4th order if you are tuning at 34hz man. That design is all out of whack.

Maybe he needs to play 10hz Jeff lol

Well what advice do you have for me then? I wouldnt have posted on here if i was an expert. Lol

i wouldnt do that configuration. your better off with 3 12s facing rearward with a port facing rearward. i had 2 shocker II 15s in the trunk of a Saturn in a similar configuration and i wish i wouldn't have wasted my time. acoustics is much more complicated than just getting the right amount of air space port area and tuning..

the added cone are for the 15s vs the acoustic transfer from the trunk to the cabin the 12s will be louder..

Had a pair of those 15's sealed in a maxima trunk 14 years ago lol
