Good Day to all Acoustat experts and enthusiasts : I have 2 pairs of Acoustat Z2010s which i want to use but i don't have any power supply adapters for them.
I know they need to be driven by 9 Volt AC but i would like to know the current strength of the necessary power adapter. If you could please assist me with that please.
I will have a ton of other questions for my set-up but for now i need power first ,lol. Any help is greatly appreciated. Thank you

These Acoustat models were built in China, many years after the company was US-owned. There is very little information available about these speakers, and in fact the images you present are the first I've seen. Power requirements from the 9VAC adapter will be minimal. The 15VAC adapters used on US-made Acoustat models were rated at 150 mA, so I think anything in the 200mA (0.2 amps) or greater will do nicely. Based on the label, I see these speakers are rated only above 250 Hz, which suggests they are not full range, and will require the use of a companion woofer system.
Hello , Thank you for the warm welcome from everybody 🙂 and quick responses .
I will post some more photos of the speakers just for everybody's interest as soon as i get the chance to do so.
Question: I could get the power 9v AC supplies in 1000mA , would that be too high and possibly damage the electrics in the speakers? Or should i opt for rather as you said 200mA to maybe 300mA ?
Yes , the frequency range .... i will need subwoofer/s . Is one going to be enough or will it be one for each speaker ?

Using an AC adapter of higher-than-needed current rating won't hurt anything in the speaker - the speaker will draw only as much current as is needed by the bias circuit. If the speaker only goes as low as 250 HZ, I recommend two woofers (one per channel). Crossing over at 250 Hz is a bit high for a single, summed L+R mono woofer. Do you have any idea what was offered to work with the main speakers - either as an included accessory, or as a separate product? A speaker than plays only down to 250 Hz is not much good by itself. Just curious.
Hi, good evening , thank you for the reply in respect with the current strengths , and the woofer info.I have many more questions coming for the set-up .
I want to upload at couple of photos and info that i have about this relative unknown acoustat model.The pictures and copied manual is all i have, hope it helps to a database and others one day.

The manual (third page) suggests that the speakers were designed to be paired with a specific woofer system. And based on the wiring diagram, the amplifier connections are paralleled for the woofer and panel speakers. This suggests that the woofer contains its own low-pass crossover, and that the panel speakers contain their own high-pass crossovers. I still think 250 Hz is a bit high for a mono woofer, but that seems how it was intended to be used and gives you a starting point. I suggest you connect the panel speakers and woofer per the diagram and see how it works. BTW, I am amused at the manual's last page that says "since 1962". Acoustat was not around in 1962.
I believe the intended woofer for use with these panels was the TNT200 (see attached *.pdf)
NOT to be confused with the TNT-200 Amplifier.
Searching through my archives, located a few pics of the panel elements outside their frames, transformer, and the HV supply/crossover board.
Looks like they retained the 2 segment panel configuration from the Spectra series.

Hi all , i found some power sources to drive a pair of the z2010's ..connected them to the one subwoofer(Sony ,i think sa-w 2500,) .. and my Sony STR DB 940 ( i think ) ... as speakers B. Speakers A are the standard Sony speakers as seen in on of the above photos. Drumroll........,lol..... They played . That's all. Sound was not what i hoped it to be :-( , not as clear and bright as the normal speakers. I feel a little let down by their sound quality.The (woofer) bass , middle , treble was all there but not spectacular , unfortunately . Could it be the amp ? maybe some equalizer adjustments could help.
