Inductors for Australian diyers?

[damo21]

Hi, I'm trying to source some decent inductors with low DCR but not having much luck.
Can't really justify importing from Madisound for just a couple of parts. Maybe find some nice 14AWG copper wire and roll my own? I need a pair of fat 2.2mH inductors with <0.3ohms.
Any other suggestions would be awesome. What does everyone else do for crossovers? Cheers

try a search for Australia in the title under loudspeaker category and browse the threads for usefull info.

I have used a few inductors from plain wire, foil, litz. at 2.0~2.2mH don't recall any having DCR lower than 0.3Ohms.

Try some of these :

Aranmar Acoustics

RzAudio

Soundlabs Group

W.A.R Audio

Acoustic Concepts

how much would you like to spend?
crikey!
Seriously though, I have some of those ERSE super Q's from parts express, they are very low resistance.

Could always try Rick at Equinox as he rolls his own (inductors not joints ) and in large wire sizes.

Speakerbits also have the Solen Litz but not with a DCR that low.

I sell the Solen 1.6mm but DCR is 0R33 and you would need a larger wire to get below 0R3.

Which ever way you go, they are not exactly cheap.

After months of searching myself the results are.

Rick at Equinox.

he uses 1.8mm round, or 3mm flat ribbon.

a 2.7mh in 1.8 was quoted to me as $44 each plus freight, and the 3mm (which I got, sexxxxx) are $131 each .16 ohm.
Have a look at the site in my sig, goto nsew -> my audio -> ektaclone for a few pics and info..

Or Solen 1.6mm at wes/rzaudio.

Sound labs do have 2mm but for 2.7 was going to be About $100 each..
Compare that with Ricks...

Thanks guys, yep, looks like i'll be ordering from Rick.

0R16 fark man that thing must weigh a tonne! (4kg..) bet its worth it though. I can't justify that much money on xover components for my little project hehe.

I'm copying one of Zaph's designs. I hope it sounds as hot as it looks! Should go well with my recent Peerless XLS 12" cubic foot sub.

If I had not completed my speaker then I would choose to use a higher DCR inductor first and test the sound. 2.2mH would likely be used in the woofer and you could patch down your tweeter with a resistor to match. This will reduce the speaker efficiency and would have only a small or no impact on the sound if done properly. Once I like the speaker and fix the XO then I would get the low DCR ones. Presumed that you were not running a 300B or 2A3 amp the reduced efficiency should not be a big deal.

WES sells the Solen inductors but I am sure Rabbitz could get you the same stuff at a better price. If you need a lot of inductors you may directly order them from Solen.ca

Yep, I'm not going crazy with very low DCR yet, I just need an inductor that wont dissipate all the woofers grunt as heat i think $40 is a pretty good trade off for ~0.3ohms. I'll see how it goes. Thx
