rockFord_Expedition Posted February 15, 2015 Report Share Posted February 15, 2015 Or better yet, how do you know what type of sub an enclosure will like? Like say you have a certain amount of airspace, and you know you want a certain type of enclosure and to play a certain bandwidth well. You know the power you will be running etc. How does a non biased person chose the subs best suited to their situation beyond the quantity and size? Can T/S params lead you there? Is there any good free reading out there that can teach me this? Edited to better reflect the intent of my question.

redwolf2 Posted February 15, 2015 Report Share Posted February 15, 2015 Contact the manufacturer and discuss information and experiences with them is what I would do. Link to comment Share on other sites More sharing options...
OrionStang Posted February 15, 2015 Report Share Posted February 15, 2015 Contact the manufacturer and discuss information and experiences with them is what I would do. Wrong answer most of the time. The manufacturer will always give you a safe or base-line recommendation. You need to know all the parameters of the sub and learn how to apply those numbers to a enclosure.

kirill007 Posted February 15, 2015 Report Share Posted February 15, 2015 Loudspeaker design cookbook by Vance Dickason. And modeling is the only way to really know. Obviously to know for what type of enclosure it likes, you just calculate the EPB (Fs/Qes) anything over 100 is for ported enclosures, anything under 40 is for sealed enclosures.(and anything in between, you can choose) Thinking is the root of all problems... You ALWAYS get what you pay for. Link to comment Share on other sites More sharing options...

Mustang2dakota Posted February 16, 2015 Report Share Posted February 16, 2015 You take the Qes and divid it into the Fs of a driver. Depending on the number you get will show what enclosure is ideal for that individual speaker. 0-50, Sealed is highly preferred. 50-100, The speaker will work well in both ported and sealed. If it's 100+, then it is highly preferred to use a ported enclosure.

RooTxBeeR Posted February 17, 2015 Report Share Posted February 17, 2015 BAM https://docs.google.com/file/d/0B_l73GVBBlIUNTc2YTc2YTktNTNmYi00YWNmLTlmY2ItZTU0MTRhMzdkYTAy/edit?pli=1 Edit: Although what Mustang posted best helps figure out what enclosure to start with. I am still interested in what if any T/S parameters determine how much volume will be required. Like let's say 2 speakers have entirely identical T/S specs, except 1 parameter. Could that 1 make one speaker over the other require more, or less air space? And the same for port area. I remember seeing something about how bl and xmax are directly related to the amount of air space required. Just never fully looked into that.
