This is fantastic. I wish I had the means to cut the acrylic like that.

Will removing the series resistor increase response in mids? EDIT: Removed the resistor. After removing I enjoyed it more with the white dampener than the brown.

Update: brown resistor is slightly better. You really have to be focusing on a difference to notice. Slightly warmer, less fatiguing.

Moved the resistor as recommended. I seem to be getting much better quality now. Next I will try with a brown dampener instead of white.

Okay, I will move it. Should the tape be left on the driver vent?

It is a 20ohm resistor that is green because of the solder mask. It was my understanding that it should be there. Are you suggesting that I should move it so that it is on the positive leg of the mmcx but before the zobel instead of after? Or do you suggest that I remove the resistor entirely...

I sealed the tube into the nozzle with uv glue and it worked great. Here is the same shell on Aliexpress. https://www.aliexpress.com/item/32873071827.html?spm=a2g0s.9042311.0.0.10d54c4dnjtQ2z

I will keep that in mind for my next set of customs. I have this connector but I haven't used it yet. It's very large but the retention offered might be worth the struggle to fit in the shell. https://www.aliexpress.com/item/32841238822.html?spm=a2g0s.9042311.0.0.10d54c4dnjtQ2z

I did make sure to compensate for horn size in the nozzle. Here is the shell. The opening for the nozzle is very small so it is difficult to fit more than one tube through it without consequence. It will comfortably fit one 3mm OD tube.

Will do. I bought these specifically for the notch in the side because I absolutely cannot prevent the connectors from pushing into my custom shells. It's a problem I still struggle with and is ultimately the reason I've had to rebuild every pair of customs I've finished.

Just finished a set of universals using the RAB 32257 design by dhruvmeena and Choy Wei De. I wanted to build something inexpensive to use with a Bluetooth adapter while at the gym or climbing. This is only the second set of universals I've built. Previous builds include three iterations of...

Has anyone tried using a vibratory tumbler to smooth their shells prior to lacquering? I'm thinking about picking a cheap 5lb tumbler from Harbor Freight and a high grit media to try it out.

I'm working on an MASM2 build in a universal shell and I have the drivers and zobel configured but I can't figure out how anyone has been able to fit the two 3mm OD tubes into a universal shell. The only way I can get them to fit requires that they be squeezed to the point that the tubes are...

Thank you. It seems like I will have to buy an enormous length of tubing to get the 1.2mm ID. Do you think it would be okay to just use 1mm ID/2mm OD instead?

Does anyone know a supplier for the 1.2mm/2mm and 2mm/3mm tubings used here?

I bought this one. https://s.click.aliexpress.com/e/b2z0SbhO The results are no different than I got using two nail lamps taped together. The timer for the lamps and the capacity helps a lot with workflow. I can cure more than one piece at a time. It doesn't do anything in terms or curing that...

I'm having huge issues with pits or air bubbles inside my shells. I carefully check for air bubbles when I cure with glycerin but I always end up with pits on the inside. Is there a particular way to avoid this?

Those are the types of mandrels I have. Thank you!

What tools are best for sanding shells before buffing and lacquer? I've sanded by hand and I've used sandpaper mandrels for my Dremel and I'm still having trouble getting into the tight curves and bends of the shell. What grits are recommended? I've been starting at 600 and working up to 2000...

How did you get an account to order from them? I tried to register once and got declined because my address was clearly residential. I offered my business address but they wouldn't accept me because I'm not an audiology professional.

If nobody else noticed, Soundlink has a sale on their Aliexpress store that ends in 4 days. GVs are currently $89.38 for a pair. All their other BAs are on sale as well. Might be a good time to stock up.

I've gotten to the point where my shells are coming out very nice before buffing. I'm trying to refine my process a bit to work out the slight imperfections that I'm still getting in my finished shells. I've figured out that the imperfections I'm seeing are from inconsistency in the waxed layer...

I'm not sure that the curing time would differ at all. I've never used the Egger resin or duplicating material. Somebody else might be able to answer this for you. I try to keep the walls of my investment as thin as possible but not so thin that it gets damaged when I remove the impression.

I'm still just starting but I've made several attempts at shells with Fotoplast both with and without dyes. I've found that the greatest improvement in shell quality came from a few things. The first is patience. Spending the proper time and care from the very beginning of the process has made...
