Just got these speakers today!! They are awesome and worth every dollar!! Hook them up and set the settings to my liking and the sound is amazing!! I played some of my favorite music thru them and it doesn’t seem to sound like there’s two speakers. I only had them turned 1/2 way up and that was loud & clear enough for my ears-and I like my music loud if that means anything to you. If you’re thinking of getting them...get them!! It’s almost scary to think that there are bigger models.
Sounds Awesome! Couldn’t tell there was two speakers.
Simple features for anyone to figure out.
Ease of Use
Super easy. Just remember to use the the aux cord that came with it if you want to plug in your iPad or phone...cause I tried to use my old ones and it didn’t connect.
Good and sturdy.
These speakers/monitors are worth every dollar!
Manufacturer Support
No need.
