Not that I imagine they are bad(!), but has anyone here had any experience with them? Anyone know who the Australian agent is? What are the prices like?
Hey Circlotron 🙂
PAS Speakers are good speakers, however, they are
steered toward PA applications, not home.
I currently have the 2880 C which sounds very good.
Were you interested in their 15 or 18 drivers?

The 2580C is big enough for me! anyway, in a 6th order bandpass box it seems to tune up better. I am throwing away lots of sensitivity though. From 99dB down to 87dB.

hmm...................
Providing you have ample amount of power, to gain the
SPL you need, I don't see a problem.
So, what's the TS Parameters of the 2580 C?

I had a pair of 15s some years ago.
They sounded good to me, but I really did not do any extended measurement with them. All I wanted was a PA woofer to play damn loud in my home, and they did that.
I called up their tech support, and they were always very courteous.
So I would buy them again, but in truth, all I can verify is that they worked as a PA speaker should.
One issue is cone excursion. PA speakers have a small linear cone excursion compared to something like, say, the Tempest. They did seem to have a rather large mechanical excursion, which I tested because I ran them off a turntable without a rumble filter, lol.
The best way to find an Australian agent, if one exists, would be simply to call the company. PAS is not one of the better known brands even here in America.

I Agree
I remember picking up a Beyma 18 LX 60 for $100,
and, the 18 G 550 for $200 on Ebay a year ago.
Brand New, I might add. Just because no one knew
what they were.
If it was JBL 2441 or EV 180B, the bid would've closed at $300

Did you purchase this speaker already?
This speaker would work much better as midbass
woofer.
Preferbably Horn Loaded Straight Horn................

Nahh... Actually, I'm looking long and hard at this Peerless thingo now. It's Qts is 0.21 but if I can raise it to 0.5 by upping the amplifier output impedance a bit then I think it will be a winner. In a normal 300 litre vented box - woohoo! 😎

A) Is upping the amplifier output impedance a good idea?
B) Are you going to do this using tubes or transistors?
C) How are you going to do this?

C) How are you going to do this?
a) As a random thing to do, no. But if it raises the Qts to a more suitable figure of 0.5 then yes, I think so.
b) Initially a pair of LM3875's that I am already using as a sub amp.
c) see diagram. Instead of returning the - input of the amp to ground as usual, put it to the top of the current sense resistor. For a given output voltage, if the positive-going load current increases then the top of the sense resistor goes a little positive. This voltage is fed into the - input of the amp via the 10k resistor and amplified x22. This causes the output voltage to droop a bit with the increased output current, just as if there was a resistor in series with the output. The output impedance can be varied by altering the amount of current-sense resistor voltage fed back into the amp.
Of course, I havent actually built one yet... 🙄
