http://www.d-s-t.com/link/peerless/data/pdf/830500.pdf gives the speaker dimensions; from http://jwilson.coe.uga.edu/emt725/Frustum/Frustum.cone.html my rough calculation is 3.6 litres. Is the amplifier from Parts Express? http://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=300-794&DID=7 ? I figure 4 litres; less for both if you take into account the thickess of the cabinet. And I may have it all wrong! The main reason I'm replying is that I notice you are in Brisbane - where are you obtaining the parts from? I'm thinking of something similar myself. What box design are you making?fb said:Could anyone tell me what volume is taken by a Peerless XLS12, XLS12 passive radiator, and a PE 250 watt plate amp (300-794)?
I've taken a guess with 2, 1 and 1 litres respectively. Close enough?
Thanks for the info. Let us know when they have been constructed. I'm not sure when I'll get to mine. I've not even ordered anything yet. Still not decided among vented/sealed/PR (but cost is a factor for PR). As far as the calculations go, have you been able to work anything out more exactly from those links?fb said:I'm making a 54 litre passive radiator, WinISDpro design is attached.
You're welcome to have a listen once mine's done. I guess I'll just aim for between 54 and 60L, unless I can get an exact answer.

According to http://www.maximacar.com/calculating_volume.htm "The basket displacement for an average 12" woofer measures 209 cubic inches." That is 3.425 litres (http://www.convert-me.com/en/convert/volume), so my initial quick calculation of 3.6 l appears pretty close.fb said:Not really thanks, my knowledge of geometry isn't sufficient to make some of these calculations when some data isn't available. I was hoping someone might have measured, or have a standard method for estimating volumes.
