Hi (First Post)

I'm experimenting with building some headphones from scratch and would love some input on picking some appropriate full range drivers/speakers. I've been combing through the parts-express website and there are quite a few nice looking full range speaker options in that measure 2 - 3.5 inch.

Not really sure the appropriate ohms and wattage to look for... :confused:

I know most of these aren't designed specifically for headphones but do you think any of these would work in a set of oversize (Hifiman size cups)?

Some I was looking at -

HiWave BMR5 Compact 2" Full-Range Square Speaker 5W 8 Ohm ... er=297-212

HiWave BMR12 Compact 2" Full-Range Square Speaker 12W 8 Ohm ... er=299-208

Replacement Speaker Driver for Bose 901 4-1/2" 1 Ohm ... er=290-922

I know you can contact Sennheiser direct and by drivers or cannibalize cheaper headphones but that is more then I want to spend. and I'm already working on some modded t50rp...

Any help, thoughts or links would be much appreciated. thanks!

i hope you have some old headphones with large earcups for your driver choices which i think might be a little on the overkill side but if you can make them fit into something and not give you a neck sprain,go for it!
you might want to google search 1" mylar "button" drivers with 1/4 to 1/2 watt rating that might be a better category of driver for the application you have in mind but that just me.

You should find out some old headphones and take some parts from them. It will make your work easy.

My personal combo is Audio-Thechnica Airs ATH-AD700 (big cans) and CMoy OPA2134 DIY driver. Or go for the Oatley K272A small tube driver. Not sure about making headphones. Even cheap ones can sound excellent.
