Singles vs Pairs in ported box performance?


Recommended Posts

I tried to search, but perhaps its not working right now, so my apologies as this may have already been covered.

Is there a difference in overall performance if 2 subs are in sepearate ported boxes, as opposed to a single larger enclosure?

Edited because I noobed out there. heh.

A single, properly designed enclosure has the potential to be louder

I started this thread because I had a new idea for the back of my vibe, and while my understanding of enclosures is decent, I have much to learn yet.

Anyway, sometimes I have to haul bigger stuff around for my job, so I am constantly having to fold the seats down. This also involves having to move around my box that houses 2 rockford 8" subs. (Thats right, I roll hard with the 8's... single voice coil even. My budget for car audio is tiny.)

I figured I might could build something where both speakers are on the outside, leaving the middle area to haul stuff with the seat down.

So first I built a quick prototype so I could hear how the actual box will sound. Its at .6 cubes tuned to about 37Hz. I think it sounds great, but wonder what others think about folding the "L" port into an "S" shape to get the length needed for tuning. Am I losing efficiency with this type of design?

I figure Im close to about halfway done, and I will probably post more pics when I finish up. Input on the design good or bad appreciated. Thanks for looking.

its 3/4, and was laying around in the garage. otherwise might have gone with 1/2.

I am curious about this also for a slightly larger enclosure 8)
