Rated 1 out of 5 by from No idea I bought the Stage A120P 500 watt subwoofer so my daughter an I can watch movie with an awesome sound system on her birthday, we can't have a birthday party for her or go to the movies since everyone is locked down due to coronavirus. The sent me a Stage A120 bookshelf speaker instead and are taking forever to respond to my emails. So now it looks like our birthday plans are Twice ruined. If they had overnighted me what I actually ordered when I told them of the error instead of taking a full 24 hours to respond this could have been avoided. I am extremely unhappy!!

Rated 3 out of 5 by from Great sub. Missing parts. Great sound and profile. The sub shipped without the grill/front cover even when it was ordered from JBL.com CS reps helpful and logged a ticket but the cover isn’t available and will take a couple months to ship.

Product Q&A

Hello there. I have 2 JBL Venue Series Stadium speakers at home. Will they work fine with the JBL Stage A120P powered subwoofer??? In general which subwoofer do you recommend would work great with these two tower speakers???

Asked by: DJ Acho
Our JBL Stage A120P is part of our Stage series. This 12-inch powered subwoofer that has 500 watts. You may expect a slight difference with the clarity of sound if you'll be using this with your JBL Venue Series Stadium Speakers since they are from different series.

Can you pair this togather with any of the jbl soundbar ?

Unfortunately you cannot, the soundbars have their wireless subwoofers that can sync with them.

Dear JBL, I currently have the JBL Bar 3.1 soundbar and subwoofer. Is there any upgrades that I can do to this system at all. Like adding rear speakers or even adding another subwoofer to it. Please let me know if there is anything at all I can do.

Asked by: Anonymous
Our JBL Bar 3.1 doesn't have any upgrades available to it and is a stand alone system.

If I connect this to a wireless receiver will I be able to play music via bluetooth?

Asked by: TM58
Hi there, it would depend on the wireless receiver if it's capable of playing music through our JBL Stage A120P. We would recommend using a wired connection instead so you won't experience audio cutouts when playing wirelessly.
