Chasing dipole bass quality....
The Big Question....
Could something like a single 12" XLS or a single 12" RSS be satisfactorily operated as a low-mid-bass driver in a dipole?
Say something like from 80 - 300 hz.
If so (drum roll please) what would the neccessary path length be in order to achieve a satisfactory result?
What could be expected in the way of efficency?
Could a satifactory SPL be reached in the 80 to 100 Hz range before the driver ran out of excursion?
These are all very troubling questions
Im not lazy - I'm just stoopid - Isn't there a program available for modeling these parameters??????

Thorsten Loesch´s tool will help to determine max SPL too.

No takers?
Okay Okay,,,I'll come up with some math from SL's webiste, maybee that'll help.
Dipole bass uses up excusion big time...but what if you don't even try to go low...maybee just to 80 or 100 hertz....
C'mon I need some insight !
There is a path length that defines what the response will be..what would the path length need to be?
Could one "big excusion" woofer provide the SPL if all it had to do was deliver 80/100hz and above??????

The Sd and xmax of your drivers are fixed. Path length and SPL are directly related variables: http://www.linkwitzlab.com/spl_max1.xls
When you determine what will

p.s. don't forget to add 6db for half-space
When you determine what will
that you deem sufficient (@80hz), your path length will be revealed
