Default Data Sheet for Extremis 6.4

Hi,

I bought a couple of 6.4's assuming the specs would b pretty much the same as the 6.8 but I just saw they are not all that similar. However I can't find a data sheet for the 6.4... can anybody help?

I haven't been able to find it either. It actually appears as though there isn't one. I've even come across a couple of outdated product pages specifically for the 6.4 version, with a llink to the datasheet for it, and it downloaded the 6.8 datasheet. You might have already seen the following, and perhaps it's what caused you to post this thread, but I just came across this as well..

Hi I didn't see that so thanks for posting it. I did find another thread about it on the same forum though... but not much use.

Having looked at the T/S specs I was planning to add a bit of extra mass to the 4 Ohm version since I have already built my box expecting the 6.8. The only think I really want is the impedance curve, I can measure everything else for myself.

Hi Bob,

Am I right in thinking you have, or had some sort of connection with Adire?

It looks like I will have to email he address on their website and ask for an impedance curve for the 6.4.

Hi,

I was the Canadian distributor for Adire. Currently I am an XBL^2 licensee and have additional drivers in development; the SDX7 has just been released and the SDX10 and SDX12 are in process.

Please email me from my website if you want to take this offline.

Bob
