First let me say I know these subs are junk, but I need to build a box for a pair of 12" Xpods. Is there any one out there who knows how much air they need for a sealed or vented box. All I can find on the internet are basic specs but no box sizes.

 

I can't help you with the box building part of it, but if you get the proper box and don't abuse them, I think you'll be pleasantly surprised as to how good they "can" actually sound.

 

You need to be more specific on the model. It should be on the magnet. But sealed for 12" xplods 1-1.25 cu.ft per subwoofer and ported 1.35-1.75 tuned per to 37hz

 

The model number is xs-l121p5. It is one of the older red ones.

 

There is nothing but basic info on them. The only thing i can suggest is email there tech support and see if they can get you the parameters. But as i stated earlier you will be fine with 1-1.25 cu.ft sealed and 1.35-1.75 cu.ft. tuned to 37 hz after sub and port displacement.

 

Thanks I will try a 1.25 box I have in the shop and see how it sounds.

 

they say ported at 1.67cubic ft tuned at 34hz sooo the port style is up to you .. square, slot/ L port, round port ( flush or flared)

 

ohh and um
