How Loud is a 70s Sunn Coliseum at 4ohms?

    So I’m looking into purshcasing a 70s Sunn Coliseum bass head and I’ve read that the amp runs at 320 watts at 2ohms. I was wondering if anyone has had any experience running the amp at 4ohms and if so is she still loud?

    Welcome to Talk Bass. :)

    This amp has very obsolete technology putting out very little power by today's standards. How loud it will be will depend entirely on the sensitivity of the speaker cabinet(s) it’s connected to. A single 4Ω driver will get something but if it is loud enough only you can gauge.
