Its problematic with a sharp cavity peak and resonance- it could have used a stub tuned around 290Hz. (browser add-on EQ8 parametric EQ can be used to check where problems lay) I'm not sure yet how it behaves with aperture pulled. As is it would probably work for an electronic drum speaker.
Any ideas for a pipe stub to put in the rear chamber?

Hi!
I would love to build an XKi as a box for electric bass guitar.
I am a total newbie to the whole topic but do have some carpenter-skills and tools...
Already started a new thread in the fullrange-forum, maybe its better to post it here(?)
I do already have the speaker - its an OBERTON 10B200 - 10"

I was told that for e-bass the the cabinets are tuned around 60Hz when vented.
Is there any chance that one of you guys could help me out designing that bewished cabinet?
Kind regards - Flo

I have couple of spare PA130-8 drivers. My Yule project is to build a pair of XKi speakers with them. I'd like to try and optimise the dimensions. I notice that the manual for the legacy version of Akabak 2.1 has a simulation of a 6th order bandpass enclosure. Shouldn't be too difficult to modify for the XKi design. It incorporates acoustic masses at the bends and end corrections for the ducts. Interestingly, it models the front and rear chambers using multiple ducts rather than single enclosures. Elsewhere I have found that the end correction for a duct terminating into an infinite baffle (rather than free air) is +0.425 x hydraulic diameter. For a circular duct, the hydraulic diameter is simply the actual diameter. Generally, the hydraulic diameter = 4 x cross sectional area / perimeter.
That’s similar to the Karlsonator model I have in Akabak with the variable front aperture. The trick is to make the aperture variable and allow some direct radiation to pass through.
