15" sub advice.

The rest of the system is just sealed 2 way monitors with an 8" woofer which starts rolling off at 100Hz.

Lab 12

Hi, out of curiosity i did both sealed & vented designs with the LAB12 using WinISD. Please see my Att. Zip for the .wpr files 😉

Also a few screenies to be going on with down below.

Plus either should compliment your 2 way monitors which start rolling off at 100Hz. Personally, i'd go with the vented.
