The Super Bees - Garage two way build

So what was the problem with the Rustoleum? Drying time?

So what was the problem with the Rustoleum? Drying time?

Hey man, sorry - got busy with actual work stuff. I am honestly not sure what went wrong with the Rustoleum. I don't think drying time should have been the issue, as I left the yellow and black stripe on the cabinet for more than one week in my air conditioned house before trying the clear coat. I didnt' smell any more off-gassing or curing enamel smells, so I thought I was good to apply the clear.

The only thing I can think is that I messed it up by wet sanding after the yellow and black stripe layers to give the smoothest final surface for the clear coat to lay on. I sort of doubt that though... one cabinet took the vinyl decals fine without any lift-off and ruining of the clear coat, and I prepared both of them the same way.

Ultimately I want to increase the finish quality of my builds by moving to HVLP in the future, so I can only hope that better products will equal better quality (assuming I develop enough skill with the spray gun!) At this point, the speakers are installed and serving the purpose well, so I've called this project complete. Brain space is now devoted to future projects!

Hey Keith,
I've been reading through this thread with great interest because I'm looking for a budget 2-way TM design in 4 ohm, and your Super Bees seems to fit the bil perfectly. I was wondering if you ever got around to making a write up, and if it's something you're willing to share? And is the XO shown in post 91 the final one?
Thank you!

Hey Soren, here's the final writeup. Final XO is shown in here for sure. Not sure if thats changed over post 91. If you have any other questions please let me know!

Thank you so much! Amazing!

Is it correct that there is no baffle step compensation in the XO because the speakers were designed to be placed close to the back wall?

If so, is there a way to implement af baffle step compensation in the XO?

If I were to use the speakers as a monitors, which would be placed away from the back wall, would they then lack bass?

Thanks again. Love the design!

[Soren]

Thanks a lot, Keith!

That makes sense. I think I will get the parts and try your XO design if that is okay with you? I assume so since you’re sharing the write-up

I another question. In the documentation you say that you’re using a pre existing enclosure, and I can see its dimensions but not the actual driver layout on the baffle. Would you share the distance from the top of the baffle to the center of the tweeter? And if I keep that distance the same as your design as well the width of the baffle, can I then make the speaker slightly taller (about 1 inch) while keeping the internal volume the same?

[KEtheredge87]

HI Soren, Yes please have fun with the crossover design and build it as you see fit. I will try to remember to get those dimensions for you. I still have the fusion360 CAD files that I can pull up at home. I just can't access them here at work. I'll try to remember to pull them this evening. As for changing the height of the speaker, you would probably be ok by increasing the height by 1 inch and keeping the internal volume the same. It will have *some* impact on the response, as the total baffle area for reflecting sound is now larger, but maybe not enough to horribly throw off the XO design and response. Impossible to say for sure without new measurements of the woofer / tweeter behavior in that setup.

As long as that does not make the tweeter equidistant from the three adjacent edges, I agree.

Hey Soren, Here's the woofer and tweeter baffle placements. Everything is aligned center on the baffle. Cabinets have a 1/4" roundover on the edges, so take that into account when considering tweeter placement.
