Hello @LeelaKrishna,

Please tell us more about your application.

For example, is this a stand-alone application or part of a 70-volt PA system.

It may be useful to share the make and model of your amplifier.

Best wishes,

Hi @LeelaKrishna,

Thank you.

I now understand the speaker specifications.

However, I don’t understand your application.

For instance, if you are using a 70-volt PA system you may be interested in:

This transformer could be installed (soldered) with a specific power. you could also use a selector switch to determine power.

Sincerely,

Aaron

Hi,

We are using 100v

Also the required transformer should be capable to function in harsh environment with water resistant

Apologies @LeelaKrishna,

I am unable to locate a 100 V matching transformer in the DigiKey system. As I understand the situation, 25 and 70 V are common in America, while 100 is more common elsewhere.

I was able to locate several open frame transformers in an online search. Locating a robust potted transformer may be more difficult.

Sincerely,

Aaron

Hi LeelaKrishna, I’m also not finding any good options in our system for an audio transformer meeting your requirements. We don’t really carry options that are robust in the way you’re describing while also matching the power and voltage requirements I would think are required based on your description so far.

I believe there are specialty stores that carry what you’re looking for, though I’m not personally familiar with them. Hopefully someone else on the forum can get you in the right direction.
