Great blutooth speaker. very loud and powerful. Drives my neighbors nuts. 🤣 2 things i DONT like, 1) No remote. 2) no wireless microphone.

It worth the money it’s a great buy

It has a great sound and it’s real easy to move around on the wheels. It’s a great buy for the price.

Sounds great. BUT, it needs proper SPEAKER GRILLS. To protect them.

Nice speaker, extremely underwhelming bass

I really want to like this, but for the price and size it is hard to justify. For having 2 massive 15 inch subwoofers the bass is virtually non existent most of the time. I played some bass heavy music, and the only tume the bass soinded decent was with the bass boost on. However, huge problem with the design, when the bass boost is turned on, it cancels out the other eq options so the vocals are not near as nice. The volume is ok after its played for a bit, but again it does not feel anywhwre near an 1800 watt system. The speaker looks great and the lights are a nice touch. There are a lot of good qualities about it, but dont expect to be blown away by the sound. I have a little maybe 6 inch sub in a thx computer speaker set, and it puts out more bass than these 2 15 inch subs, it is quite emberassing to be honest. I will likely keep this as i got it for the 100 off sale, and it will be a nice party speaker for the house. I will buy a cable to see if it works to add one if my svs subs to it. If it works properly it will be perfect, if not it will be returned.

HelloWe appreciate your feedback. The reason the Monster GI30s Bass Boost feature cancels out the equalizer settings is to prevent distortion. For additional support, please reach out to us at support@mymonsteraudio.com, our customer service will gladly assist you.

Really impressive for the price!

I'm assuming these are still newer since there is nothing you can find online for these guys. Wanted to hook up to an AV receiver to them.. but unsure how. But other than little to no reviews online, I figured I write something. But these are insane and phenomenonal. Clear crisp sound through Bluetooth and just so much power. Could stick this thing in your car and have portable sub woofers hahaha

Hello,<br /><br />Yes, the Monster GI30 can connect to an AV receiver using a 3.5mm RCA cable. First, plug the RCA cable into the Monster GI30&#39;s &#34;In&#34; port, then connect the red and white RCA connectors to the AVR&#39;s left and right ports.
