Proline X P6D-P | Dual 6.5" Ported Subwoofer Enclosure | V3

Box is very well built

I used this box with a pair of CT sounds meso 6. 5 subs. The box specs were really close to what the CT sounds recommended at 40hz and . 6 cubic feet of space. The box carpet looks awesome and the inside of the box has bracing which you wont see on the cheap boxes. The bass output is really smooth and hits hard and low. I highly recommend this box!

Oh my! If you have a pair of 6.5 subs this is the box you want!

Interior of box had and has 3 big (3 x4 inches) chunks hanging broken off of where the speaker holes were cut out. Your only option is lowest impedence on your speaker pair because there is only 1 set of terminals. Original add said this was a good box for Massive Hippo XL64 but they will not go inside these holes unless you take the voice coil Leads apart off of the frame and then they hang free with no support. Way too much work to try to make this work with Massive Hippo XL64. Waste of money, sending them to Goodwill. Also, if you read the massive material it says to tune these to 45Hz……..
