  • Da Sub Pumps

    So something a little different for an enclosure. In this case, a 30 gal 4 cu ft sump pump basin. The 6x6" port gives it a tune of 44hz. The drivers are Eminence Kappa 15LFCs. Total weight of each is about 50 lbs.
    I was asked to design and build a system for a new community center. After contacting Jerry McNutt at Eminence, they donated the drivers for the project. These will be installed at the Pax Community Center, a multi purpose outreach of State Street Community Church. The Pax Center houses a clothing and food pantry (that currently serves some 1800 people each month) and a community meal free of any charge. The space will be used for multiple family friendly events
    (Movie nights, stuff for teens, meetings, and classes)

    Great idea for an enclosure. Are they plastic (and how thick...just curious)? Are you going to cover them with grills?

      They are a plastic. Polyethylene to be exact. As they are going to be flying some 12 ft up, I'm not planning on grills but that may change.

        Hey, I see a spot right in front of the right table to squeeze another speaker if you slide the crossover bits a bit.

        Seriously, that's a cool thing to do.

            I found these at Menards, but they are also available at Home Depot. I also found 20 and 72 gal models (2.67 and 8.2gal respective) I used Gorilla glue epoxy to initially hold the port into place and then used a loctite 2 part epoxy to do the final seal and fill any gaps.

            As these will be flown, I added a couple of 2x4 braces, also expoxied, that will have 1/2" eye bolts and stainless steel cable to hold from above and brackets from the side. The ports will fire to the center of the room. Power is being supplied by 1 ch of a beringher inuke3000. The other channel will power the 4 mtm units. Those will be on a later post.
