Sencheezy 689 Posted April 19, 2014 Also, can anyone input about my question in regards to port area of an BP? 0 Share this post Link to post Share on other sites
Quentin Jarrell 671 Posted April 19, 2014 All volumes are net. You will find in most instances the volume of the port will exceed the net volume of the chamber itself. 0 Share this post Link to post Share on other sites
Sencheezy 689 Posted May 1, 2014 BOOM! I think I found something guys haha So, this whole time, we've been referring to this enclosure design "sealed box into ported chamber, an 4th order bandpass. BUT, I think I found something. Doing a little google search, I found this site. http://www.mobileinformationlabs.com/HowTo-1Woofer-BoxPaid-New.htm Now, I'm not sure on it's accuracy, or creditably. But, it sounds good to me. Anyways, the box is called, Single reflex band pass Sealed enclosures that play into a tune enclosure that acts an s a low pass filter... This increases efficiency within the “pass band” or usable frequency range of the enclosure.Pros: Can be made very efficient within the pass-band”, can be designed for increased gain in a band of frequencies, increased power handling within the band.Cons: Distortion hard to hear so, it’s very easy to destroy woofers, increased gain designs sacrifice low end response, relatively large enclosures very difficult to design and build, very sensitive to design/construction errors. -------- So, tell me what you guys think? 0 Share this post Link to post Share on other sites
Sencheezy 689 Posted May 1, 2014 Damn, just did a search and found the wiki link, which describes this orientation as Compound or 4th order band-pass enclosure. fml lol 0 Share this post Link to post Share on other sites
Omega_Ace 5 Posted May 29, 2014 I have one question. When figuring out the port do I use net our total after displacement? 0 Share this post Link to post Share on other sites
Omega_Ace 5 Posted June 5, 2014 I used the program and got the box figured out for two ethos 12's and I'm goin to do an external port but do I follow the port area for a ported box ( 80 sq. in.)? Or since all the sound comes from the port do they need a larger port? I want to give it an honest shot and get the best results. Thanks anyone 0 Share this post Link to post Share on other sites
