Krakin Posted November 20, 2013 Report Share Posted November 20, 2013 Pretty much been looking into designing a few open baffle enclosures or variations on that. Would appreciate anything anyone knows about them.

Trey_Dog650 Posted November 20, 2013 Report Share Posted November 20, 2013 Open baffle? 13 Kia Forte Build! 07 Hyundai Accent Build ***Super Seller*** N8ball2013 And then he gets to say ok all you guys were right. im sorry for being a dummy poo poo head.

Krakin Posted November 20, 2013 Author Report Share Posted November 20, 2013 Open baffle?Such as this. I am looking for information on the amount of baffle needed around each individual driver to keep the direction of the front wave the way I need. Edit: that picture seems to incorporate a bass reflex enclosure for the midbass/woofer Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist?

Tecomah Posted November 20, 2013 Report Share Posted November 20, 2013 So kinda like free airing ? 750??! Yeah, fuck that. Fuck this website, fuck SMD, fuck Steve, fuck all of his butt buddy mods, and their couches.^ DON'T BE A DICK LIKE THIS GUY Team Subsonic Lows Link to comment Share on other sites More sharing options...
Krakin Posted November 20, 2013 Author Report Share Posted November 20, 2013 A form per-say, but it is controlled and calculated to have the waves reflect off the baffle in certain ways.

Krakin Posted November 20, 2013 Author Report Share Posted November 20, 2013 Infinite baffle?no.. A variation on the 'open baffle' approach is to mount the loudspeaker driver in a very large sealed enclosure, providing minimal 'air spring' restoring force to the cone. This minimizes the change in the driver's resonant frequency caused by the enclosure. Some infinite baffle 'enclosures' have used an adjoining room, basement, or a closet or attic. This is often the case with exotic rotary woofer installations, as they are intended to go to frequencies lower than 20 Hertz and displace large volumes of air. "Infinite baffle" or simply "IB" is also used as a generic term for sealed enclosures of any size, the name being used because of the ability of a sealed enclosure to prevent any interaction between the forward and rear radiation of a driver at low frequencies.

CommonSyns Posted November 20, 2013 Report Share Posted November 20, 2013 Infinite Baffle: These are great for applications where trunk space is at a minimum and usually the easiest and least expensive way to add a subwoofer to most sedans. Not having to construct a box is an advantage, but many vehicles will require a new rear deck panel and/or vent to be constructed to accomodate even smaller woofers. These custom vents and panels could cost as much or more than a prefabricated or custom box. Infinite baffle set-ups require a woofer with a beefier suspension for high power handling and one with better cone damping. This set-up will be less efficient in reproducing the lowest frequencies as compared to other second order or higher enclosures.In any free air application, the back seat and surrounding panels should be removed to seal any possible areas where energy could be lost. It is crucial to separate (seal) the back wave of the loudspeaker (woofer) from the front wave of the loudspeaker. If not, bass cancellation will occur. This is also a good time to rid and deaden the trunk and surrounding areas of any unwanted noises and rattles. I feel stupid I didn't realize this was posted in the home theater section. Sorry.

Krakin Posted November 20, 2013 Author Report Share Posted November 20, 2013 This is posted in the home-theater section so I don't have a trunk... Which I now see you noticed An open baffle doesn't always eliminate rear wave formations.
