Amazon has the Sony GTKXB90 High Power Portable Bluetooth Speaker on sale today, bringing the price down to just $348. That's good for $100 off of its regular price tag, and makes this a great price for a pretty incredible portable speaker from Sony.
This speaker from Sony is part of its Extra Bass lineup, so you're getting some incredible bass out of this speaker. That is also thanks to the three woofers and two tweeters inside. The Sony GTKXB90 is a great speaker that is also fairly large, that is going to fill up the room with sound, and can even fill a backyard with sound pretty easily. The GTKXB90 is a larger speaker, but it does have a battery inside, which can last around six hours of continuous playback. There are DJ lights included here, so you can really be a JD with this speaker. The lights can be turned off if you'd like as well. Sony includes all kinds of ports on the back for connecting it to other devices, including a TV, which is nice to see. If you're looking for a really good portable speaker that allows for some deep bass as well as great sound overall, then the Sony GTKXB90 is a great speaker to pick up, which can be used wirelessly or wired.
