The HM130ZO is NOT a mid/woofer. It is a midrange only driver. You can see in the above picture that a highpass 2nd order filter at around 500 hz is recommended.

It is an excellent midrange and came to fame in this application:

It must be used in a 3-way system as this person came to understand:

Hope this helps.

Thank you for these datasheets!

I have made a two way design with it. The cabinet was about 8 liter, crossed @ 3 kHz to a Scanspeak 2010 19mm dome. A very decent sounding loudspeaker. The impact/ bass is not bad at all (-3 dB point around 70 Hz).

I find that this website comes in handy quite often.

I've got a pair of Hm130z0s and they do sound wonderful. I got mine for £10 each on ebay and that includes postage :P Lucky old me. And I have so far only used then as a mid.

Hmmm.......

Simply not true. Parameters indicate it would work fine as a mid/bass.

2mm is not brilliant excursion but better than most fostex full rangers.

If used as such (reflexed) it would suit low power class A / class D amplifiers.

The Audax Z0 series was marketed as having "aerogel" cone construction.

When I was shopping for 6.5" drivers for my MTM DIY speakers in 2000, I chose Audax C0 speakers (Carbon Fiber), but Madisound accidentally shipped me 6.5 Z0 aerogel drivers.

The aerogel's had a very interested feel to them, they were soft yet flexible and frequencies seemed to roll off of the cones smoothly and naturally.

I have often wondered if my system would sound substantially different with aerogel drivers instead of Carbon Fiber ones.

I do know that Aerogels sold at a higher price point than CF Audax drivers...this could mean that the manufacturer intended them to perform "better," but that is open to debate.

Hope it helps

In my opinion, Audax's Aerogel is the best cone material ever.
