Sometimes less is more, I`ve tried squeesing alot af subs in a very limited space (compared to the ideal volume), just not worth it. Have done some simulations with isobaric setups and it gives a slight boost on the lower frequenzy`s. And lower volume than requiered will often cause a peaky response.

Doing a wall setup usually require more volume (up to 50% larger than suggested box volume), the woofers need some air to get really loud. Example: The first box I made for my DD Z9518`s barely broke a 150 (okey, non walled and too little box volume) Then when I made the "real" one with a wall with about 30% larger than suggested volume it did 154.5, and it did 150+ from 23-60hz. The most common mistake people do is making too small enclosures for the woofers. Some times it`s not about surface area, but volume

Yup! Sorry for the metric measurements, but I guess ya`ll figure it out

I`m giving away my box design I made some time ago for my "mini" woofers. This box was designed for 2 DD 1508`s in a stationwagon, but I think it would work great with Sundown 8"s as well. I`ve tested it some other cars and were loud in every one of them (not testet in trunk cars though) But if you want a good box for your DD`s or similar woofer, I think this box will suit you well. Tuned to ~35hz. The sketchup does not show kerfs, but you get the idea. Legal score In the kick Port score The box Hope you`ll enjoy it!

Thanks! Poppin dust caps, pulverising voice coils and tearing up the suspension is fun, got a few subs left laying around so they will get the hammer next weekend lol

Thanks Ed!

Got rid of some old woofers I had laying around, the wall socket and the amp did the job quite well, lol And threw in a couple of hairtricks as well

That will be fine, diffirent time zones

Could you send it to me when you can? I`m gonna shoot some vids tomorrow and would love to have that in there

Okey, think I need to edit my title. It`s a slowed and bass added version of the "in the air tonight" song right? I tried to do it myself with audacity but it had a lot of clipping and I didn`t get it low enough. And I don`t have the patience right now to learn how to use it so I will rather have someone with experience to do it

Thanks man, but not quite the one I`m looking for, but I appriciate your help As long as it`s not under 20hz it`s OK, it falls on it`s ass below that, lol But no, I`ve tried to get in touch with him but I think his inbox is full or something.

I just gotta have this song! The one in Tommy McKinnies vid, In the air tonight, if you make it to 25-38hz range that would be perfect! Or to make it like it sounds on the vid. PM me and name your price I will pay through paypal. Here`s the vid of the song

Thanks man! I think I got to do some Trail and error as dwright27 said And when building a wall, either your standard ported one or a clamshell, tuning is gonna change a bit (usually drops a few hz down) so I think I gonna tune it a tad higher on the calculator and rather adjust it after if it`s needed

I wanna see your buildlog NOW! Gonna run a similar setup as well, so I could use some inspiration from you.

You got mail you tease, lol

Thanks Oldsboomer! But is there another design that is more efficient than this? diamond or a tunnel maybe? The subs where sent from italy a couple of day ago and I got about a week until they are here so I wanna be sure that the design I use is the most efficient

what kind of program should i use to get the right results then?

I have NO intensions of having a 50hz tuning frequenzy, lol I`m aiming for a 35ish tuning frequenzy, I shall try that and see what the calculator says. I`m trying to replicate what Frankie Rio did in his lexus, hoping it will produce decent pressure in the car Edit: Got a 38hz tuning now (and 7cubes of port volume, lol), that`s more like it

So I`ve been thinking about doing a clamshell for a while now, the subs I`m most likely gonna use is (12) 12" Hertz Show SPL 2x2ohm and 3 dynabel BF8501 (5000watts each). I got about 14 cubes of net volume, according to Torres calculator the tuning frequenzy is 49.9hz, but I don`t know how long the actual port length is (where it ends) I just put the length of the plate behind the baffles. Couldn`t find the recomended box volume of the subs on their site, but here is the link: http://www.hertzaudiovideo.com/Doc/hertz_SX300D_tech.pdf Here are some pics of what I`ve sketched up, does it look OK? (even made the measurements in inches just for ya`ll lol) I am willing to pay someone for the job if I think youre qualified. Edit: the wall thickness is about 2.5 inches.

Thanks man, but I think you do have alot of really nice women in the states too

next time I should throw a cup in there and make a 3 girls 1 cup hairtrick, lol

Edited some of the clips I took yesterday

Thanks guys! Updated the first post now

Some friends and my girl wanted some beat and volume in their hair so I gave them whitegirl, lol here`s another one for ya`ll More coming soon, got another vid uploading now Comments are always appriciated
