Nice sounding 3-way from cheap drivers

[edinm]

During corona virus lockdown I build pair of 3-way speakers from cheap drivers laying around for years. It was one of these projects with not so much expectations but at the end I am listening those gems for weeks and they are fantastic. I decided to write something about it because maybe there are more people with these speakers and don't know haw to implement it. I finaly find some use fot them 🙂

Drivers are:
Woofers - AuraSound NS8
FR (or mid) - Peerless TC9FD18-08 3-1/2" Full Range
Tweeters - Cheep ebay chinese tweeters from ebay (MK Audio) costing 6.5 USD

Box for Auras are around 17 liter, port 4.7cm x 18 cm.
Separate box for TC9 and tweeter.

All is maded from 18mm MDF and double front baflle 36mm for woofer.

Crossover: 12/12db, 6/6db
Woofer: 9mh + 100Mfd
Mid: 68Mfd + 4.7 mh/0.1mh
Tweeter: reverse polarity 2.2 Mfd + 2.5Ohm

I didn't had any data for tweeter and capacitor value and resistor are choosen simply by listening and huntch 😀

I don't have any equipment for measurement so it is not pro work but it sounds great for me.

Here are what VituixCAD shows for woofer/mid with crossover, also some pictures of completed speakers.

Cheers for all friends here, stay safe 😀

Good work! They certainly look the part, both physically and graphically.

Stay safe and stay occupied! 😎

Those look very nice! Those woofers remind me of the old Elemental Designs EHQS-8's.

Short recording

I tried to make a short recording using my iPhone. Not great but characters of the speakers can be heard 😀 (sort of 😀)
