Rated 5 out of 5 by from Refurbished Boombox My refurbished Boombox just arrived and I'm enjoying it as I write this. I wanted a Boombox since it came out but price was an issue. I saw someone with one at the beach last weekend. It is so powerful its hard to compare it to smaller speakers. I said to the owner I liked the sound but its not cheap. The guy said it was a bargain at full price. I went to the JBL website during a sale and it was still pricey. Then I saw they had refurbished ones and the price was like "oh, heck-yeah!" I bought it immediately and wondered if I would get a banged-up, dirty speaker with defects. What I got was perfect in every way. I cannot tell it from new and it so far runs perfect. I would buy a JBL factory refurbished speaker again without hesitation. As for the performance of the Boombox its a bass monster and it can get very loud. I am so glad I got this speaker. I'm not new to Bluetooth speakers. The Boombox is to speakers what a Mastiff is to dogs.

Rated 5 out of 5 by from Amazing sound quality I bought this 34 days ago and have loved it since I don't like getting it dirty but theres nothing JBL can do about that lol but it has enough power to shake some smaller things on your walls and put a thump in your chest if your in a bedroom sized room and sounds great the only thing I hate Is how easy it is to scratch and wish it had a backpack case thing but I wont complain everything has its ups and downs If they ever do make a JBL boombox 2 I will be buying it the day it comes out for sure so I can always have the biggest waterproof portable speaker on the market it is great and fills every need I have as i walk down the hallways of my school with tremendous bass filling the halways.

My brand new JBL Boombox makes kind of parasite background noise when switching on/off. First I though about the firmware upgrade. Still running under version 2.0 so should I go to 2.2 (or latest) and could this be the problem ?

Asked by: zlodenev
Hi Guys, For instance the power supply has been replaced so it sounds amazing already. Excellent product indeed !

How loud is Boombox compared to Extreme? What is the difference between JBL Connect and JBL Connect +?

Asked by: allalone
Hi! The JBL Boombox is much louder and has much more bass than the xtreme and it can hit 20hz lower than the xtreme, it has four 4 inch woofers and two 20mm tweeters, it can go as loud and maybe even louder than the harman go +play. Jbl connect allows up to two Bluetooth speakers to connect and play simultaneously, jbl connect + allows 100+ speakers to connect and play simultaneously.

Want to use it in classic truck, friend uses Bose soundlink and sounds good, Wish could hear the JBL boom box. Be honest, will it sound good in a cab of a truck? I don’t buy stuff and return it.

Asked by: Auto Detailer
The JBL boombox can even produce quality music in a medium sized room so a cabin shouldn't be a problem and should be able to provide you quality sound.
