200s cab plan request

[catalin gramada]

Hello everybody.
This is my very first post on Forum.I.m happy to meet so many peoples interested by Sunn projects.
I have a pair of Fane axiom 15b-300 which collect dust on my shelves and was thinking to put it into 200s cab. I have acces at a wood workshop and also I'm pretty skilled in wood craftshift to can build one from scratch by myself. I tried to contact Mr.Conrad without succes for the plans. So please if one of You can share the original plans for 200s, as accurate should be I much appreciate, please.
Sorry for my bad english. Thanks.
Best Regards.

Thank you Watson.
If dimensions are right I can work with it. You pick'ed up from yours cab, please? I'm little confused as I know 40x24x15" are external dimensions, but represented inside into pdf. Thanks.
Best Regards

I don't have a 200s cab.  Just literature I collected that I thought might be better than no info at all.  Many here no doubt have more info that is less generic than what I posted.

Thanks again Watson. It is a great support for beggining. I will try to collect more data to be as close as I can. It is very easy to ruin a big project, as Sunn 200s it is,by differences in details and the details do the difference I believe.

Have you emailed Conrad from his site?

He is usually quite good about responding to people. I can see if I can help you get in touch with him as he is a local friend of mine.

Russian Baltic plywood aprox.0.75".bracing hardwood 1x1", I prefered to put the bracing for baffles outside as it can serve as support for metalic mesh as well.(I have not care too much to preserve the original fabric frame).
The baltic plywood comes in european standard as it is a product made in Europe. 12,15,18,21,24mm are standard dimension which have not equivalence into Imperial system, Also Sunn seems to use another kind of plywood. The russian come now in 13 veneers layers for 18 mm thick - that means 0.7" and not 3/4"(o.75").
I don't find this minor diferences as semnificative as I consider more important to know the quality of plywood which was used. Thanks.

 I think most vulnerable part at this project is assamble where the 45* sheet join the reflex port. Think also Mr Conrad used 0.5" thick sheet just because is more simple to fit the 45* cut with the straight one.Can be used also a 3/4" sheet for the "port flare" instead of 1/2" one and think is justified as time those sheet takes all shocks from speaker.Imagine what is happen with a 300w ,11mm excursion "upgrade"speaker replacement into full throttle.On the other hand don,t know how much the resonances from that sheet comes into sound scenario.

Please, be aware! the port is also restricted by the width of the furring of protection grill. I don't know in this moment what dimension have but can consider to do the baffle from one single pc.just need it.

One thing you might not be aware of is that many, if not most 15 inch speakers will not fit in a 200S cabinet. The issue is that the original JBL D series speakers were not very deep. Try to fit something else and the magnet assembly hits the 45 degree board before you can get the mounting holes to line up. I've never tried it but an E-140 might not even fit.

Hello loudthud.
You're right.
Thank you

hi, thanks
had some times to start my project.I have no problems to fit the drivers from inside
scaled a litlle bit to acomodate better my drivers parametres to 42x25x15. first impression, honestly, way too big and too heavy for mobile aplications.

Cheers

That's a whole lot of plywood you have there, looks great but surely weighs a ton. A factory 200S cab is pretty hefty, your oversize replica with the thick plywood must be very cumbersome indeed!
