I have built one WO 36"x36". Im using Two SEAS L26RFX/P aluminium cone Bass. To be honest, i am very happy with it, it does sound great, especially once you find that perfect possition. Its great fun to build. It provides great sounding bass, even at the low power of my drivers. Im only 19, but i have been around audio equipment my whole life. Both me and my dad agree, its well worth the build if you've got the time and space. However, for the true audiophile, there are better enclosures out there that are maybe less fiddly to build, and more easy to accomodate.

we managed to get a wo in a car facing the boot witha 12" and 1 comp driver mid top, all running off macrotechs on stage as we didnt have a car amp, got the guy from uk iasca to sit in the front, the look on his face was priceless
shame the stage was too far away from their stand for us to get it metered....

I Finally finished My first WO and I have to say it definitly creates some sound pressure! I am quite pleased with the results. I am going to build the WO32 next.

I was highly impressed at the sound of the wicked one enclosure.  I first built the 2x3 enclosure and being a carpenter by trade I built a almost perfect enclosure.  The plans where perfect.  With the buy one get one $80.00 rockford fosgate deal I loaded the enclosure.  After pulling my subs from my montero i installed the wicked one.  I hooked it to my JL AUDIO 500/1 Amp. and did some tweaking.  After about 20 min it was amazing at the amount of sound that pumped from this enclosure.  After 2 weeks I replaced them with sound spliner 10" subs and the bass is overwhelming for the amount spent.

I built a 24x36 WO. I originally put a pair of Radio Shack 10" in it (50w ea). The sound was ok. I realized later that the bolts holding the speakers were loose and the speaker basket was slamming into the wood whenever it got very loud. I never fixed it because the next time I had it open was to put in a pair of DHM-108s. Quite different! I tightened the bolts and took it to my church, where it was used weekly for a few years. It was used in conjunction with a pair of Peavey Black Widow 18"s with about equal volume. Over that time, the bolts worked loose again and it once again sounded bad.

The last time I opened it, I completely repainted it and added nylon nuts (metal nuts with nylon that keep them from working loose). I also redid the gasket seal. Now, it's in a Dodge Caravan with 300wrms x1. I was actually going to say I was dissapointed with it's sound, but then I discovered that only one of the 10"s were running! The wire connecting the two had fallen out! At lower volumes, it sounded ok, but at higher volumes, it had bad compression. No punch. The difference was night and day!

People have asked me how big the speakers are and how much power I run. Saying 2 10" or 300w is enough to get their jaw dropping. This is all with a bad ground connection, stock alt, and a weak battery. I probably only have 100-150w!

I once used it in a small/medium venue (200 ppl) by itself for bass and it could be felt at the back of the room with 250w total power! It easily kept up with a pair of 15" mains.
