I have a big rack PA setup, but am looking into a small light simpler powered mixer to use for small gigs. Almost all of them include two 4ohm capable amps, usually one amp for mains and one for monitors. I want to be able to use four monitors. Does anyone make decent quality 16 ohm floor monitors (12 or 15 inch) so I can run four of them resulting in a 4 ohm load? I've done searches and haven't found much. Two 8-ohm mains will be fine, so that's not an issue.
