No, I have not because the box is massive for sealed but I think I'll give it a try in the summer to see what it does. The port is small but not miniscule It still functions the way it is intended to but with almost 150sqin its not the 215 I had hoped for plus with bracing and glass, etc. I am sitting right around 10sqin percuft. Like I said, no numbers box just a unique daily driver is all. I ended up using these drivers because they perform better in this application as opposed to small stiff spiders and high power handling (my car only has and will ever have 240A of max output) -Drew

Check it out! -Drew

The range of frequencies change as the ratio of box volume to port change. A small box with big port will peak higher at tuning and roll off steeper as you move away from tuning while a big box with smaller port will operate with a wide range and small boost at tuning frequency. My box plays pretty flat with a gain at 39 and 49 which sounds pretty good on music whether rock or rap. Now, A big box with a big port works wonders as well I'm not saying that it is bad if I could have worked it I would have but we all know that a car is not the optimal place for doing what we do. -Drew **I hope you are not under the impression that I chose that side thinking it was best case because I didn't. That is as big as I could go staying within box dimensions and budget. It was built to be the only DC shaped port wall not to stop all other walled 18s.

Yup! something like that The original port ~215 sqin of port was just to big and after all that I realized that because the box narrows in the back I have to seriously adjust my port size. Also, because its cut in layers The CNC time was getting expensive so I could only do so many layers which landed me with a pretty port but not optimal SPL. Also, If I wanted Raw numbers I would not put the port on the bottom either this is more of a daily amusement for friends and myself rather than a serious # monster. Original http://i40.photobucket.com/albums/e216/saxwonder05/DC2.jpg I drew everything up on autoCAD and used the Island function to get the internal/external area of the DC cutout and used those numbers to calculate overall area and port volume compared to the estimated net volume of the box. Actually, My overall volume # is more of a guess than the port numbers. -Drew

Thank you sir! I'm still trying to convince the wife to let me dump $ on amps -Drew

Yes it does, the port and outer baffle were CNC cut. It is a classic music box. Big volume low port area plus the 10" spiders and 4" coil give it big excursion and a nice wide band of output. Thanks for looking! -Drew

Gratz man- Its a cool place for sure!! I was a sound tech at Marine World for several years and am out in Fairfield atm Plenty of bass shows in the season to keep you addicted -Drew

The Autorama we speak of is in Sacramento the 20th and 21st It is the Hotrod/show car event but this is also where Doug holds the first Db drag/Bass Race event of the year. We just take our little corner of CalExpo and get loud while and enjoy the nice cars. They are two separate events- held on the same day at the same place together so the db drag/ br is referred to as "Autorama". Not all Autorama locations hold db drags -Drew

Couple Numbers so far- 150.0db @20hz (tone) 153db+ @26-27hz (Rubberbands Slowed) 155.4db @ 37hz (BME Click?) All on two DC 3000.1s sealed Vid: Thanks for looking! -Drew

Look in the "DC sound lab jeep Part III" vid and you can see a quick pic inside the tunnel -Drew

The Ateam has been working with DC on a few trick products- one being a flat carbon fiber cone. Ateam is working on the protos at the moment and as far as i know there is no planned release date. -Drew

Order it up from Boss man himself! I sent you a PM- shoot me a txt/call when your free. -Drew

well gawdamn man! come out and listen to the Jeep! it says in Berkley and comes out to Fairfield for vids/building! I also have an Oscope (in fairfield) and you can jump on it whenever you'd like! on that much power I would get a Level 4 for sure -Drew

What do you mean by "bay area" ?? Like- San Fran Bay area or down south bay area? if you mean "DA BAY" as in Cali I can hook you up. If not, well then i can say that a standard lvl 4 will work fine on a 1500 as long as the signal is clean and you dont clip it to hell. If you have the change and want the upgrade a lvl 5 coil wont hurt any and it is a better coil. You really dont "NEED" an XL with 1500 but it will also work just fine and would allow for an upgrade in the future if you decide on it. -Drew

We went into it pretty blind as well because neither of us had any extensive experience designing bandpass enclosures. Although this is a "sealed tunnel" about 2cuft per driver at some point any build of this size will get turned into a bandpass when the cabin and tunnel get included in the numbers. I went into it knowing the sealed chambers were pretty large and wanted the lower extension because of it. If I were to build it again- or have any suggestions for somebody considering building one- I would say talk to a bandpass guru and have him look at the numbers. We lucked out in getting the response we were looking for but I can foresee it easily not going the way you plan it to. -Drew

I actually dont have the song myself- sorry! I needed it for portions of the vid editing as well -Drew

Second Daytime Vid is up! Comments Appreciated!!! -Drew

hahahaha yeah its a pretty solid enclosure design. Thank you everybody for the support I will keep this updated as its sealed and tweaked. -Drew

Newer Vid! I like to start it at 0:45 -Drew

The goal of this build is to play extremely low, as "safe" and "reliable" as possible while also putting up a good score for when he goes to shows every other month or so. To achieve this we went as high as possible with motor and cone, while keeping watt per woofer low and in a sealed environment. -Drew

^^^^ Lulz -Drew

Lookin good so far!!!!!!!!!!!!! 2" wooden dowel to brace the largest open panels and zee tunnel. So- It was almost exactly seven days from the moment I laid the first glue joint on the first woofer to the point of it playing (two of four amps and unsealed) but I think we did a hell of a job in that amount of time. Here is the first vid we did just after tossing it together -Drew
