Excellent SQ Enclosure

Great SQ Enclosure.... it hits the highs and LOWS equally. It doesn't seem to really peak at any one frequency, even where it is tuned to. This design requires only one sheet of any 4" x 8" material you decide to use and will fit in most medium sized trunks with an opening of 17" or greater.

18 Inch Ported Enclosure

Box hits pretty good. My friend and I used this design after his brother built one from speaker box lite which didn’t sound good at all. This one here hits just right. Speaker breathes good and the lows are nice

Very happy with the design if you are looking for a great box that can be built for under $100 dollars these designs are for you. Don’t get crazy spending all your money on a box built by someone else take pride and build your own
