Home-Made IEMs

Made a new IEM with 10cm of 0.5mm silicon tube for the HODVTEC as low pass at ~100Hz. Thunderous bass...need to either find some resistors or close some ports. Playing around with the acoustic low pass is pretty interesting though!
 
Also, HODVTEC has really weak bass slam o.O

The Knowles GR drivers and the SWFK both sound nice and smooth. I wonder why no manufacturers ever used GR in their designs?

The best thing to understand is that while we're all trying to be so modern with our designs here, IEMs with balanced armatures and "speakers" will be kickin' it old school until the next thing. And from what I can tell, that will be a long, long time.

I find GR pretty good for full range. It drops off before it reaches the low lows, which makes it suitable to use with a dedicated bass driver. I got them off Taobao, which sells all kinds of weird drivers that mouser often doesn't stock.
