Very true… you … Very true… you need to seal that box tight, which is also why MDF is used due to the density. The exception to this is ported boxes, they are also sealed very tight except for a special sized vent that is used to tune the box so it plays much louder at the tuned frequency.
Common … Common misconception…. You should be worred about standing waves in the room OR car with a subwoofer, not the box itself. Low freq waves are really long (56.5ft @20hz 22.6 ft @50hz 11.3ft @100hz). Anyways, to form standing waves, the faces would need to be at least half the distance of the wave. Equation: Standing Wave (hz) = speed of sound(1130ftps) / 2*distance. For 100hz to be a standing wave, you’d need a box 5.65ft long. For a standing wave @ lower freq, the box would be even longer
mdf warps over time … mdf warps over time when they are huge sheets setting vertical… glue MDF into a sub box, it won’t warp!! only way is a HUGE box, which needs bracing for the weight.
MDF can also warp when exposed to the elements, (water). PARTICLE BOARD would FALL APART in similar setting.
You do realize particle board is the crap that cheap desks are made out, right? You know the ones with the glue on finish that bubbles up after you put a drink on it??? … ya I wanna make my sub box out of that!!
I’m no expert, but … I’m no expert, but I think you just need a system with a higher output. However as I understand, it may just be the style of your box. A non-ported box will produce cleaner notes and frequencies while a ported box is designed to give you that “boom” factor. But i also had2 10″ subs, mine were JL w1 and they sounded GREAT. I was powering them with a TMA 500/1 amp.
Hi all, can some1 … Hi all, can some1 please help me, i have made a subwoofer box and it sounds awsome! However i am trying to get the real deep bass, the type of bass you only feel, not hear! I made a bandbass box with 2 10in pioneer 350w rms subs and powering them an old school RF Punch 200x. I am starting to think it is the amp. As i have had experience with this type of enclosure and it was really good with those DEEP notes. Where am i going wrong? Could it be the amp?
If Google was gonna … If Google was gonna buy Youtube, they should’ve gotten their servers situated to run the videos faster. These guys buying up other peoples start up companies should know that they should be equiped to handle the traffic and the tasks that they’ll be up against!!!
for the circle draw … for the circle draw a nice circle and drill a rather large brill bit near the edge. next use a jigsaw to cut out the circle and wallah
Its commonly used … Its commonly used because its denser than plywood or particle boards. Denser wood is a big thing for accustics because the type of wood you use and the enclosure design can make or break a sub’s output and sound quality. You could have a sub known for good SQ or high SPL, but a box built built like crap or not using the right type of wood would ruin its performance. ED, uses a new type of wood boards BTW, called EFS. Read up on it on their site, its way better than MDF!
