The kind that won't respond below 120 hz and make bass drums sound like somebody is beating a stew pot with a spoon. Try music with compatible instruments. Shamisen Bagpipe Banjo Tambourine Clarinet Flute Violin Erhu Get the picture?
Ginguy Posted February 13, 2018 Posted February 13, 2018 How about instead I buy good quality speakers.... 1 1
tsar4 Posted February 13, 2018 Posted February 13, 2018 Had a pair of old Panasonic bookshelf speakers with torn baffles & a pair of Infinitys. I had to move & put the Infinitys in a box marked "Books". I had the original Panasonic box. Idiot movers stole the Panasonics, I was holding on to them intending to replace the speaker cones. Jerks - serves them right to steal garbage.

wacky1980 Posted February 13, 2018 Posted February 13, 2018 you can make a pair of shitty $30 speakers sound great if you build them into an appropriate cabinet. go buy some 4-1/4" car door speakers and cut them into an old 30-caliber ammo can. bass falls from the sky and fills up your boots.

That could include a bass reflex tube. Now, you're talking.
wacky1980 Posted February 13, 2018 Posted February 13, 2018 nope, no ports. lock that box down. the rigid metal walls sound great without a port.

You just did better than I did. What did you use as a hole saw blade? It had to be tough to get such a clean cut through the metal.

André Toulon Posted February 15, 2018 Posted February 15, 2018 Did Michael J Fox cut that hole for you? 1

I can't afford his time. I don't have enough practice in using the saw. The saw is a very recent acquisition. Fortunately, cover grids are available on eBay. That would give the box a more professional look. Also when I acquired the box, it was held together with finishing nails. I reinforced all the joints with #12 x 1.5 inch wood screws. That stops the rattling during drum beats. To avoid splitting the boards, I predrilled the holes for the screws.
wacky1980 Posted February 15, 2018 Posted February 15, 2018 you should be mounting the speakers on the outside of the box, not the inside. also, there's a lot of math behind porting: diameter of hole and length of port tube vs volume of cabinet and air displacement of speakers. if you don't do it right, it can actually make the cabinets sound worse.

I'd appreciate the help, if you know the math. The box interior is 10" front to back, 9.5" top to bottom and 16" side to side. Thanks.
wacky1980 Posted February 15, 2018 Posted February 15, 2018 (edited) i don't know the math, but as a general rule of thumb, you don't port small boxes. you can try to calculate it yourself with this calculator if you can figure out the required fields to make the calculation. Edited February 15, 2018 by wacky1980 i didn't want to fuck with it. that's why i made a sealed box.
