welllllllllll. it's about 3.6 cus @ 47-48Hz. armed with a board, a circular caw, a jib saw, 2 cans of caulk, some screws, few assorted other tools, and a 4hp. i made this ugly ****er :)had plenty of extra caulk i just used up the extra and spread it in place's with my fingers ::snare:drum:symbol::.....

pretty simple slot port with the port on the bottom, sub fireing up. i made the side panals a little longer so that there's be a lip sticking out that was used for a better grip when lifting and also for the ghetto fab amp rack to screw onto without those screws (only had the long ones for the box build) wouldnt go into the chamber. other than the extra caulk and lack of decorations i think it turned out alright.

peaks right around 50Hz, maybe a little higher, tomarrow im gonna start testing with a better tone disk which i lack right now, my old one was hella sracted and only one on me had it in 5Hz incriments. overall its definitly a little louder at its peak than the daily box box xould do, and the sub takes the burps very well for only haveing about an inch of clearance from the pole vent to the nearest panal (top of port). box will work great for bass race and short burps.

still love those lows in the daily box :)


we redrew them close to conserve on wood but i was lazy and didnt snap a shot of that, but you still get the idea with this one.

SPL can be quite a bit smaller, but literally less than half the typical size for an 18?

Hmmph.

4hp's do especially well in small enclosures,

I think u shoulda had more port area tho :p

yup, i used that exact handsome african fellow with the shinny teeth to make my cuts :) he as agood ole' chap, didnt scream too much as i used his grill to saw through the wood.

ya these things are right up there with MT's but in half the airspace....i forget if he used 1 or 2 of his visonik 4000d's for the exact test but his 4hp was louder than the 18 MT in half the airspace. it seem s like it has the potential to get alot louder, you guys are probly right about the port area, i can cover the pole vent any closer but i could probly cook up some ideas to increase the port area.

if i break 147dB on sunday ill be happy considering how little breathing room the pole piece has and not haveing enough port area...thought about how it sounds some more and im sure i'll have again if i play around with it and get some more port area

thats basicly what i did with mr jib here. did a jimmy spliff job too i might add.



so here's a thought........loose the slot port by taking the top (of the port) off and cutting a piece thatll plug that port hole...then maybe use areos since i cant make that port taller since the motor will bei n the way....if i did that how many, what size, and what direction to face them....?

the box is so small and studry that it really doesnt seem to need it. even if i did there's really not room for threaded rods. its a solid little box

this is going to be an ongoing experiment to get a small box tuned right. it is a little louder, but nearly by as much a i was hoping for, and i know this sub is capable of more. new window goe son tomarrow and sunday ill be metering away


it's like an cold war arms race with joel and i to get loud. :)

That *****,but you can see if you get a better score the same way you did it last time.
You did a 144.7 see if goes up and youll know if the new box is doin anything.

uhh that box aint gonna get loud my friend....too small of a port width and the sub shouldnt be firing up. Ideally you want the back of your vehcile to act like a loading mechanism within itself by firing the sub AND Port back....if you had two subs, then id say you'd do better with both subs up and port back, but with single subs ive found you get louder firing the port and the sub back (at least in SUV's)

dont make me come down there and build you a box :laugh:


your box should do well if you mimic this at the very least :

or at least do this, and make all the internal edges sanded.....

yeah...ugly is nice and all for SPL. But the inside of most SPL boxes are really smooth and clean. At least mine are.

Im also going to have to agree with Mr. Snoop on this one. You might actually lose a little bit with that box. You also might of went a tad to small. Usually if you are going to build a small Pressure box, you want to throw and *** load of power at the sub.

well it peaks louder than the daily box...but indeed its too small..... back to the drawing board...

BassAddictJ
01-09-2007, 01:33 AM
o ya. it louder than my daily for suuuuure. peaks at right about 50hz with this sub and my car. havent got it metered but it certainly a good bit louder than the daily box ( still without a window :( new one tomarrow). daily did a 144.7dB. this id guestimate around 145-147...which IS loud....but this sub has to potential to break 150 with the right box. and thats what i want

Have you tried pointing the sub back and port up?

I've had good results with with that...

everyone get off his back, he has no window in his vehicle and he told me he wanted an SPL box, so i designed him a box that did a 147 on the dash....trust me smaller boxes ARE LOUDER, BIGGER BOXES ****....

have a nice day and build something louder than me then you can tell me different

the box gets loud :) if ihad more power on it itd get alot louder. and its true SPL box's work better smaller, especcially if you can put some juice on the woofer. unfortunitly i dont have as much juice as i need so i think im gonna go a little bigger (not much, maybe to like 4 or 4.5 cubs and do snoopdans horn design. im sure if i had double the power id be spankin some nice scores. but my resources are limited

its not just you man, its just on every forum here lately everyone is second guessing designs i do for people.....

sub back and port up doesn't really do anything, either all back or sub up port back is the way to go....

And 2500 watts IS alot of power, no matter what no one tells you they're not running much more than that per woofer for long periods of time without woofer failure, if they say they are they have a stupid high impedence rise and they should test it....I havn't seen a woofer that can take more than 3k for over 5 minutes without reaching thermal limitations.

Sorry for flying off again, it just seems like everytime I design a box for someone, someone else comes in and starts saying its too small or its this or this...when they don't do anything close to that numbers wise, just know what they've been told or read and havn't ever tested it.

Again thats not really direct at you Sku, just more at some others in general =)

No worries man, I didn't even know you designed the box...

I actually put an 18" MT (in a 3 cube box) in a sub back port up combo...did better then sub up port back for me...so I just threw that out and wondered if it would make a diff. for BassAddict
