ok all you designers and sketchup artists I am wanting to build a realy badazz band pass enclosure for a single sub (prob 10 in but flexable ) this box will be used as a coffee table in my friends shop waiting area the reason i am seeking designs is i am going to do the lid with plexi so the better looking the design the better
i have a few things in mind but just thought i'd throw this out there to all of you

i built decware's WICKED ONE and i was dissapointed http://www.decware.com/whorn.htm

so now i want to try again any of you have any cool 4th order (or 6th order)designs i would like to see them the sub will prob be a JL audio W010v3 maybe a JL W310v3 if you have a design for some thing specific just throw it up i'll look oh yeah i might use a MEMPHIS PR10 reguard less of what sub i use it will be powered by a JL 500/1 so output should be decent :crazy:


ok let's see what yawl can do and thank you all in advance :D

if you want to go with one side all plexi then i would think a 6th order IMO.... The only thing is is that you need to pick the 1 driver you want to use and let us know. Much like any box design it must be designed to best accompany the drivers parameters.

i didn't use the right set up i still havent thrown it out so maybe i'll try it again

ok lets say the JL W310v3 that way i can show off the sub as well

Well, any sub enclosure can look "kewl" with some craftsmanship, creativity, and a router + some plexiglass :D

As far as bandpass goes, are you looking for 4th order or 6th order? 6th order will more than likely be the loudest, but it will have a more narrow band of frequencies it can play so if you're looking for any SQ whatsoever, that should probably be scratched off the list. 4th order however you can get some pretty heavy hitting bass while still being punchy and precise because of the sealed chamber. You could still make it look nice though... have the face of the ported section facing toward the back of the trunk made of plexi and give it a nice good quality paint job on the inside with maybe some LED lights. Are you looking for something you can pop the trunk and show off at car meets/comps or something?

I'm posting from my iPhone right now LOL. No box calcs on here. When is win isd gonna come out as an app? If u want another design besides 80's I'll see what I can do tomorrow.

yes please no disrespect to 80 but this is not a one designer job
i'm looking for multiple designs
hell I might build 4 of these things just to see how well they perform
like I said I might even put up a prize for designs ubove and beyond the norm
what do you guys need ? wire?ring terminals? fuses?
chit draw me something that's knocks my socks off and there's no tellin how greatful I'd be

This is going to be interesting. Make sure to put up a build log.

Sorry to post back here so late, I've been busy as hell between box builds and friends asking me for freebie installs :mad:


Anyways, sorry if I missed this somewhere else in the thread, but I've got a few questions as to your goals and expectations of this said enclosure.

1. I think you said one woofer, most likely a 10". Have you settled upon one yet? Knowing which one and the T/S parameters would make for a better tuned box tailored to your driver.

2. What are some size dimensions within reason. Even if you have none, would you rather it be wide and deep and short? Or the other way around, just so I don't design something that is completely impractical in your case.

3. What kind of sound are you looking to get from this box? A large peak/spike for a one-note max SPL wonder? Or something that has a nice flat transient response?

4. What kind of signal is going to be pushed through this box/driver setup? Home theater/movies, or only music etc?

5. I don't believe you mentioned which you had decided upon, but are we talking 4th or 6th order bandpass? I think this is going in a home theater so I would recommend 4th because they can go lower.

no not h/t it will be the coffe table (low and wide) in my friends shop waiting area
using a JL W312v3 on a JL 500/1 and the top will be plexi so thats why i'm looking for cool desicns 4th or 6th will be for demo of sound room so decent output required
take your time and make it pretty lol
there may be a prize if im knocked oout by design
look up in the thread was contemplating using those clear areo's but will prob just do slot ports so there you go

I'm on a mac computer at the moment and I'm almost 100% WinISD isn't compatible, but tomorrow I'll get started on your design.

dappa5
06-08-2009, 09:21 AM
excuses excuses lol
cool looking foward to it c'mon every boby else submit some cool designs
if I use your design I'll etch you name in to the plexi top :eek:
i kno ikno just the thought of your work in a shop in a small sw fla town gets your heart racing:crazy: but calm down and draw draw draw :D

I've been kind of busy here lately. But here's what I've come up with so far...

I know that WinISD does not represent and exact real world application, but it does a pretty good job at recreating transient curves in respective boxes with the said driver. It doesn't account for the acoustical effects of the surroundings, but this is going in a larger room, so there shouldn't be as large of an effect as a car cabin.

Here's some of the results I came up with using the JL Audio 12W3v3 driver. First off, it appears this driver doesn't really like 4th order bandpass enclosures. No matter how much I fiddled with it, I would either get a flat response, but with low output, or a super high peak (typical of best buy bandpass boxes :crap:) so I also plotted a regular ported box. 1.75 cubic feet net as recommended by JL with a middle of the road tune @ 35Hz. It gave a decent response with fair output, better than the 4th order in my opinion. Surprisingly, the 6th order yielded really great results. With a 3 cube chamber tuned to 32 Hz and a 1.5 cube chamber tuned to 60 Hz, it gave excellent output from 30-80Hz range which should be good for your setup. Here's the transient curves so you can decide for yourself.

I'm in the process now of making a physical design to those volumes/tuning. I'll post some more stuff tomorrow.
