Frugel-Horn Mk3

Thanks ChrisB. In truth, I'm not fully grasping the parts you mentioned but I'll look them up on google once I find time.

One more quick query. I think there's a frequency chart somewhere here on this thread but I can't find it in the many thread.

Using the Alpair 7 on the FH3, what's the 3db point for low frequency? is it 50hz ? 45? 40?

Thanks,
UL

Removable panel for stuffing adjustment

FH MK3 is now second in the build queue. :)

I would like to allow for adjustment of stuffing afterwards (might have to go in different room or to different house :eek:). Also have to keep on supporting the factories who make the threaded inserts :D.

I recall Chrisb suggesting partially removable front panel for frequent drivers swappers and some pictures of the test mule cabinet too. With that, I reckon it might be possible to add reduce stuffing in part under the driver. What about for part behind the driver?

Removal side panel? The FH Mk3 is so elegant, wouldn't want the screw heads to hamper the looks.

Thoughts and suggestions please!

removable side panel would not be my first choice -

I'd probably use countersunk button head screws and perhaps painting the driver plates black to accent rather than try to disguise things. Of course around my home grilles are mandatory (for aesthetics, not protection from little fingers), so they could certainly be sized to hide the removable frames and mounting screws, etc.

Removable top

This is what I was thinking in terms of a removable top with a window. It's kind of a "jar lid" type of mechanism. :)

Let's me build the speaker without any structural deficiencies (hopefully), allows me to access both front and rear chambers for damping adjustment if required.

Raises the height of the speaker 15 mm though...

Don't worry about the additional height, but with only 3" of clearance between the center divider and front baffle, access to lower portion of fold below the driver will be rather tricky. A "grabber" tool could probably help, I've never needed to use one.
