Hey, ive made mine with only one tube because small ear canal... sound is quite nice but never compared. Tube was 3mm ext 2mm int i think and i managed juste stretch it by hands to put on both outputs at once. Will make one pair for a pal with two tubes this time.

Thank you in advance!

I had the same issue with the 1w, then I purchased a 40w k20 laser which is great.

Go dual tubes if you can.  I think it makes for better overall sound.  Cant remember the exact size tubing I use but if the smaller tube fits snuggly onto a sound port and creates a seal inside the big tubing, you should be good to go!  And your right on the money with the "bushing".  For the small driver, take the small tubing and jam it into the larger one just far enough to cover the sound port and cut it off at the end.  I prefer to use Fotoplast to connect tubes and drivers.  I use a small fingernail paintbrush.  Super glue works too.  Use the #16 for the "woofer".  It will work as a Low pass.  However, if your using dampers, you have to splice it in with the 13.  Sorry I can't post picks now, they tell a better story.

 

If you use one tube, take a pair of tweezers and jam them in the end of the big tubing and heat it up till it starts to spread open.  Took me a couple tries to not melt/tear it.

 

Good Luck!!!

I know not many use them but knowles have smaller diameter dampers, It might be a good solution for smaller inner diameter tubing.

Hello all, here is a sweet little universal set I finished up tonight. Yellow shells, rosewood faceplate, GQ driver, sounds fantastic and I love the smaller design for fit!!! It's a fun sounding little two driver!!!!

I may try to sell this set on eBay, any suggestions how much realistically I should list them for??

And what an awesome work you're doing every time Shilohsjustice

Looks awesome, Shiloh!  What kind of cable are going to include?  I would think if you put it in a nice case with accessories you could easily get $250.  Right?  How much do you have in them?

Hey guys! Picked this stuff up at lowes. Think this would work for soldering armatures? Or should I go with something else?

Those look incredible Shiloh! I wouldn't sell them for a penny less than $200 but I would ask at least $250 for sure.

They are nice looking iem but without whole set of tips, cables & packaging you can't ask for such price. Unless you go pro DIY you can't make money or profit. Its even hard to get material cost back.

Drivers GQ - $62 for the pair
MMCX Female Connector - $0.45
eStron wire (1) 10mm Red and (1) 10mm Green - $0.18
Fotoplast less than 1.2ml - $0.32
Faceplate - approx $.02
Tips - $0.85
Motion Cable 62" -$17
Hard Case - $11

Total material invested to make complete package - $91.82

I would include:
Crystal Motion Cable
Tips - S L XL
Hard Case



if I sold them for $220 that would be a nice little $128.18 profit. It is realistic to profit off DIY!!

I'm about to place an order from Plastics1 for some cables and connectors. Has anyone used their mmcx connectors before? I'm new to this, but I haven't seen any with just 1 terminal coming off. Where's the positive and negative? Where do you guys get your mmcx connectors?
