BassDoctor Posted March 28, 2014 Report Share Posted March 28, 2014 Edit: Please look at the post beneath this one for updated enclosure. Hi guys. Just got done with a rough model of an enclosure I may end up building for my car, wanted to get y'all thoughts on it. Bracing will be decided after I run some tests Subwoofers: Tantric HD10 (inverted) Amplifier: TBD, 3500w+ Ported 3 cubes when tuned to 50hz with 7x7port for comp, haven't decided on daily tuning just yet. Sealed 1 cube Interchangeable port will allow swap between daily and comp setup with various tunings and port dimensions ranging from 6x6 to 8x8 My main concern is that the area around the port will be virtually useless, even though it accounts for 0.25cubes. My car has some odd dimensions, so I will still be looking into other configurations to run, this is just a rough sketch. Thanks! 04 Honda Accord LX Sedan Kenwood Excelon X998 XS Power D3400 XS Power D1200 Singer 275A alternator with factory bypass 64 sqft SecondSkin Damplifier Build to be decided Link to comment Share on other sites More sharing options...
BassDoctor Posted March 28, 2014 Author Report Share Posted March 28, 2014 Did a few modifications, much happier with this one. 3:1 cubes ported/sealed respectively. Interchangeable 7x7 port, the one in the model is tuned to ~50hz. Bracing to be decided after a stress test that I'm too lazy to conduct at the moment. Will likely add a few fillets if I can find the right bits to do a round over. The subwoofers will be inverted. Any comments are appreciated! 04 Honda Accord LX Sedan Kenwood Excelon X998 XS Power D3400 XS Power D1200 Singer 275A alternator with factory bypass 64 sqft SecondSkin Damplifier Build to be decided Link to comment Share on other sites More sharing options...
BassDoctor Posted March 28, 2014 Author Report Share Posted March 28, 2014 No love for SolidWorks models? I can give dimensions if needed, just don't have them written down anywhere. 04 Honda Accord LX Sedan Kenwood Excelon X998 XS Power D3400 XS Power D1200 Singer 275A alternator with factory bypass 64 sqft SecondSkin Damplifier Build to be decided Link to comment Share on other sites More sharing options...
Derp Posted March 28, 2014 Report Share Posted March 28, 2014 What kind of vehicle is it going in? Just curious looks interesting. I myself am lost when it comes to ported boxes but it does look cool. Link to comment Share on other sites More sharing options...
BassDoctor Posted March 28, 2014 Author Report Share Posted March 28, 2014 Plans are for it to go into an 04 Honda Accord, port firing forwards with the trunk sealed off. 04 Honda Accord LX Sedan Kenwood Excelon X998 XS Power D3400 XS Power D1200 Singer 275A alternator with factory bypass 64 sqft SecondSkin Damplifier Build to be decided Link to comment Share on other sites More sharing options...
RooTxBeeR Posted March 28, 2014 Report Share Posted March 28, 2014 Looks nice, can I suggest something? Get some pvc pipe, and cut it in 1/4ths and put in the front baffle on the inside to create a round over on the corner. Also, what made you want to tune to 50?

BassDoctor Posted March 28, 2014 Author Report Share Posted March 28, 2014 I like your suggestion regarding the pvc, i was considering doing something like that on both the inner port edges as you had suggested, and for the corners where the subwoofer is firing into. 50hz is just a placeholder until I test the frequency of my car. I should be borrowing some equipment next week to determine it, and then I'll make adjustments to the model as I see fit. 04 Honda Accord LX Sedan Kenwood Excelon X998 XS Power D3400 XS Power D1200 Singer 275A alternator with factory bypass 64 sqft SecondSkin Damplifier Build to be decided Link to comment Share on other sites More sharing options...
RooTxBeeR Posted March 28, 2014 Report Share Posted March 28, 2014 That should help out with air flow in the box. From all of what I read, 4th orders should be tuned to the resonant frequency of the sealed section.

From all of what I read, 4th orders should be tuned to the resonant frequency of the sealed section. I've heard "resonant frequency sealed" thrown around, but I don't believe it is referring to the resonant frequency of the sealed section so much as the resonant frequency of the vehicle once it's sealed up. From my understanding, the enclosure reaches its peak near/at tuning. If you are trying to maximize SPL, you would want that peak to coincide with the peak in the vehicle, right? 04 Honda Accord LX Sedan Kenwood Excelon X998 XS Power D3400 XS Power D1200 Singer 275A alternator with factory bypass 64 sqft SecondSkin Damplifier Build to be decided Link to comment Share on other sites More sharing options...

I don't think so, I could be wrong. I have tried to read a lot of 4th orders. I would say try both, build 2 different ports. One tuned to the sealed sections resonant frequency, which is what I have seen lots do and have great success. Then another port tuned to your cars peak frequency, and see which one benfits you more in daily and SPL aspects.
