I could easily do that as my felt is vinyl backed and easy to cut w/electric scissors. Testing would be subjective. I down loaded a SA app but it looks strange on the low end. The pic is with a Sony boombox playing in the kitchen and I am in the den.

I used my K5/XKi pair to troubleshoot a Carver-Wharfdale system. We were trying to determine if his noise problem was from the receiver or the speakers. It was from the right channel Wharfdale. He was impressed at how well my little boxes performed. I had them connected to his B outputs so I could just flick from A to B for comparison.

The PA130-8 XKi is a slick little inexpensive speaker. Very pleasant sounding with a bass kick deeper than one thinks it should have.

Did it sound as good or better than the Wharfdale?

Vocals were a little better on the Wharfdale because I haven't finished padding my rear chambers yet (I still haven't purchased friendlier screws for the rear panels). I thought the bass was a little better on mine but we were near field and didn't move back to the sweet spot for either. I have mine back home now and had to rework my banana plugs, now I see the advantage of premade cords like you use.

The PA130-8 XKi really delivers on Fleetwood Mac's "Dreams", hard to believe there's no sub.

Nice! The PA130-8 is also excellent in an 0.53x Karlsonator.

hey XRK971.

I have some little 6CX and believe they are close to Beta6A in spec.

Would an XKi have any advantage with such a high fs driver over a 0.44X K15?


Def_Driver ‘Beta 6A’ | Eminence 6” speaker 4.5mm xmax
Sd=129.9cm2
Fs=123Hz

-questions when dealing with small XKi with sizable vent.

X says 17 liters total for BG20 usable to 70Hz. Not including the baffle and upper panels, but including vent and driver volumes, the total would be around 20 liters.

Is that volume adequate in hopes to reach the model's low end? What happens if the vent and driver displacements aren't included?

Does the vent at the top mitigate the cavity peak?

What would you make the internal size of this particular XKi ?
