      Great full range woofer

      Overall: 5 out of 5

      I built a 2x6. Bass guitar Cabinet, 1.23 cu ft ported at 85hz, I powered it with a 200 watt amp and used my Zoom B2, this sounds great and handles the power amazingly, I can turn it up all the way and it still is clean and full. Even on my 6 string the Low B is perfectly represented. Actually the tone doesn't really change much with volume, which is really great , it works great for electric guitar(remeber the mids are pulled down a little on my design so you will have to add some back in, but it is just a minor tweek on your amp sim), and acoustic is really amazing, because it is very flat response. For the price you cannot beat this speaker. I bet as a small vocal monitor would work really nice in the right box. There is a popular bass guitar cabinet/amp that has a discontinued product just like this and essentially with this woofer it is the same.
      Also a popular tiny guitar amp sold with a 6 1/2 speaker, essentially uses this same speaker to make their ultra small light weight combo.also uses a 200 watt amp.

      My 2x6.5 was 1.23 cu ft - i used a 2ftx4ft sheet of 1/2 inch ply wood(1/2 inch is fine because , it cuts all the really low stuff from the speaker, but you still get the bass and a little cut in the low mids cleaning the tom up.)
      the port is a 3.7 inch round hole 1/2 inch deep- you don't ned to ad anything for a port just a hole, it is perfect. i tried other porting and lower porting actually removed the fullness and did not add any real bass.
      the weight of the cab with speakers is 16lbs, pretty sweet. at 10 ft I got peaks of 112db, averages at over 100db, that is enough to cause long term hearing damage anyway

      2x6.5 bass cab
      2x4 ft 1/2 inch ply wood 4 pieces cut -18x12inches, 2 pieces 12x12 inches, you wil have to trim so they fit just right. My actual dimensions 11.75x19x12 - the 19 is because 18 + 1/2 +1/2
      interior volume 1.23 cu ft, ported at 85 hz, 3.7 inch round hole in back 1/2 inch deep(same as th ply wood), You can get 2x4ft ply wood for about $9
      16 lbs, 11.75x19x12inches and handles 200 watts
      download WINISD, and see for yourself, it really is this simple. I built the cabinet in an afternoon, I just screwed it together and no rattles, very simple all good.

      Better than you think!!!!

      Overall: 5 out of 5

      I put this speaker in a 12"x12"x7 1/4" Pine Cabinet, closed back. Put it in a music store. People used it as an ext cab to try out amp heads. It got played and played, the teachers loved it. No one thought it was a 61/2" speaker. I build custom cabs and I recomend this speaker at any price. Don't pay for a name, buy what sounds great.
