Great PA . Wide dispersion and excellent presence. You can smell the onions on the singers breath.
Thinking about upgrading the Pyle PDMW6 to PRV 6MR500-NDY for higher sound pressure levels for large gigs.

Tips & Tricks
You need some serious shop equipment to make these if you want them to look professional. I happen to have access to such. Fabrication experience is a must.

    I like this I will probably use the PRV, is there any measurements? I Plan to use this for DJ gig type work but willing to use multiple amps and a berry 2496 dsp since I already have. Any plans available thank you!
