Rated 5 out of 5 by from Thundering bass I purchased the JBL Boombox recently after researching the best portable Bluetooth speakers on the market; I decided on JBL due to the robust design and sleek appearance in addition to the massive power output and thundering bass - I was not disappointed when using it for the first time. The mids and vocals are very clear on a variety of genres and the bass rumbles without distortion at higher volumes. I have not yet tried it on A.C. power, only with internal battery, so there is still plenty of power in reserve should the occasion deem fit to blast at full power. At the price of £330 (factory recertified), this was just about affordable but you get what you pay for, high quality product with many useful features and 2 year warranty. If you want the best - forget about the rest and buy JBL! Highly recommended.

If you want quality, you pay the price and JBL delivers with this monstrous speaker! I am REALLY HAPPY with my Boombox and ever since I bought it I have gotten nothing but compliments from people. I know there are plenty of brands out there and I listened to other speakers on display, but this one took grabbed my attention big time. I highly recommend this product to anyone who wants to get the best bluetooth speaker around. Thank you JBL! Keep up the great work...

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.

Jbl boombox on battery play 2x20w and 2x30w in wall socket. So no it will br double power but bigger size of boombox makes deeper bass than 2 xtreme's.

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&rsquo;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.
