    Need help with box...picture inside.

    Heres a photoshop rendering of the box I want to build for my two 12's. Basicaly its a modified version of the box thats currently available for purchase. WHat I want to do is submerge the subs about 3 or 4 inches down and then cover them with a piece of plexiglass. Possibly include a hidden light to illuminate them.

    What Im concerned about is the loss of sound. WIth the subs completely closed like this will I lose the sound? An option I've been concidering is installing ports. One on each end of the box. On the upper outside of the box. Will this be ok? Or will I be ok without the ports?

    IF you cover the front completely you'll stop alot of sound. if you port the sides then you have a band pass box.

    I was told that it would sound like crap if I installed ports and kept the subs sealed behind plexi.

    Well i know this for sure my friend has a crx, he has two 10's in a sealed box w/ two ported holes at the top it sounds awesome and has alot of bass. But the good thing about this is he has like pyramid speakers and a jensen amp.

    What you will be doing in effect is slot loading. It should work but you may need to recalculate the volume of the enclosure.

    Slot Loading? I never heard that term before. Ive been doing some research and by completely enclosing the subs behind the plexiglass and allowing the sound to vent out through ports is very similar to band pass.

    Supposedly this gives great bass but you lose some of the volume.

    Now if you completely seal the front of the encloure. Then yes you would have a bandpass enclosure. But make sure you get the volume precise for your particular subs. Bandpass enclosures can be very tricky to get just right. And usually end up being quite large. Depending upon the size and type of subs.

    bandpass enclosures in nature tend to be peaky in their response curve. Meaning around the tuning frequency their is a big increase in output. As the frequency drops lower than the tuning frequency, or rises above the tuning frequency the output diminshes a bit. They have high output with the cost of linear frequency response.

    As its been stated band pass boxes appear to require a more previse tuning, and allow for a smaller margin of error. As this is my first system, and Im by no means a professional, I would like to allow myself some room for fault. So as not to have to do this twice, do you all have any suggestion as to what I can do.

    I know I'd like the look of the subs behind a nice sheet of plexi, and would appreciate the protection the plexi would provide but may have to seek an alternative. Its been suggested to just drill a bunch of holes in the plexi, but Im afrain that doesnt give it a very professional look. Any suggestions?

    Why not mount the plexi over the subs on some sort of legs say 3 or 4 inches or so. And cut a design in the plexi over the subs themselves. That would help alleviate any pressure buildup. and would look really cool.

    You could also then tap the edges and mount led's about every 6-8 inches and make it glow

    Great Idea Ramos, Ill give it some thaught and let ya know. Ive been thinking a lot about cutting a design into the plexi, probably just the name FireHawk , and I was wondering how I could get it to glow. LED's. Now to figure out how to make it all work.

    Im not sure what the best way is to make the cutout on the plexi yet. Still trying to research that.

    Thanks for the idea!
