Test speakers for bench

[saturated]

I got ahold of these boxes

You cannot view this attachment.

I want to mount them upside down up off the bench attached to the bottom corners of my test equipment rack

I know I can Google all this but it always helps to get valuable additional feedback from knowledgeable people 

I guess the only speakers that might fit that are oval are gonna be car speakers do you think they will work for "normal" amps and stuff 

Ok just looked it says most car speakers are 4 ohm

If you want to get a good test speaker that is 4 ohms: https://www.ssguitar.com/index.php?topic=5708.0
