GM-416-8B MLTL Corner Cabinet

[srivenkat]

Sri, the boards are angled 30 deg. from one to the next, so the miter angle for each board edge is half of that or 15 deg.

VolvoHertic, Thank you, I will try out today. I will start with the same angle for the parallel boards (6-1/2") ends as well. Also, one thing to note for the cabinet diagram based on GM

"don't forget that the 811 ideally needs to be set back in a recess along with its foam inserts same as the M19's to use its XO, which I didn't see shown"

the M-19 front of the horn has foam around two sides for about ~6-3/8" wide each and ~2" depth (not exact measurement) I couldn't attach the M-19 cabinet plan (it exceeds my current limit). I wonder whether that is something can be considered.

Thank you,
Sri

[QUOTE=VolvoHeretic;1966957]My latest version of the front baffle.

My idea of using flat rings of brass for the bass speaker and the 5"-9" dia. adjustable port grill cloth frames hit a snag. I have figured out that you could cut both rings out of the same piece of flat plate so you would need two for both speaker. A quick search found a place selling 24"x24"x1/8" 260 brass sheets, except the price is $400, so $800 total. They also sell 2'x2'x3/16 3003 aluminum for $30, I suppose it could be painted with a bronze finish.QUOTE]

Thanks Phil, I like it. I can envision coating the horn with it also.

Attaching a sample cut that I tried today, getting there!! Feel comfortable take up the curved design, thanks a lot for helping out.
CurvedSample.jpg start and end (6-1/2") boards didn't align well with 15 deg so I had it with 5 degree but 10 should be fine.

...didn't align to get the depth (26-1/2) and width. Sri

Sorry Sri, I missed that part of your message, the important measurement you need for the depth is 20", half of the width and the distance from the back of the cabinet to the front most mitered angle. The first panel to the front baffle and perpendicular to it is variable and can be adjusted for Bv volume.

VolvlHeretic, Thanks a lot. I will try another sample cut with right measurement. -Sri

have you considered laminating a panel?

[srivenkat]

have you considered laminating a panel?

Phil-G,

I like to laminate and sure it will look really nice. I'm new to the woodworking and learning the angle cuts now, getting prepared for the actual build once GM finalizes the design/internal details.

Thank you,
Sri

Yes, thanks again for the continuing effort.


Hmm, it's a [4] piece assembly, [2] for top, bottom and [2] for the sides:

it would look nice, but it would also be very strong.
