Has anyone managed to model this driver into a reasonable size vented cabinet?

This driver does seem to require big boxes, at least if you go for optium alignments. Linear Teams online calculator says >650 liters (~23.2 cu.ft.) for a vented box tuned at 31.6Hz - in return one gets a -3dB point at ~28Hz.

A 200 (7.14 cu.ft.) liter box tuned to the same frequency will give -3dB just below 50Hz - the 'cost' of the smaller box will be that the frequency curve rises above unity at around 90Hz, indicating some ringing & poorer transient response.

Even an optium alignment closed box (which you say you don't consider) will be over 300 liters (>11 cu.ft.) with a -3dB point at ~57Hz.

The most experienced here regarding various tunings/sizes of boxes with regards to driver characteristics is probably Wayne - hope he chimes in.

Looks like the ferrite version [message #43149 is a reply to message #43148] Fri, 21 November 2003 21:56 Go to previous messageGo to next message

From the descriptions of the various box sizes given and their characteristics with this driver - It sounds very much like the ferrite version of the Delta 15. Makes sense to me.
Yes Wayne... [message #43150 is a reply to message #43148] Sat, 22 November 2003 04:13 Go to previous message

The Deltalite 15 & Delta 15 have many parameters very close to each other - really seem like basically the same driver just with different magnet types.
