The BX4 shares the BX3's design but bumps the woofer size to 4.5 inches for a bit more bass presence, keeping the same 120W combined, the 1-inch silk dome tweeter, and the same cable and MPC Beats software package included. Sold as a pair just like the BX3.

With 3,896 reviews and a 4.5/5 average, the same review figure as the BX3, which is normal when Amazon pools reviews across different sizes within the same product line, it has the same massive backing.

Non bluetooth version. So these do sound good, but they havn't been great. They have an auto sleep mode that is supposed to turn off when any audio plays... but i've found that doesnt work very well. You can start playing audio and it may never turn on. Manually power cycling the speakers sometimes gets it. I Use the balanced TRS ports on the back so it's pretty annoying they function like this. The second issue is the super thin jumper cable between both speakers doesn't work well either. It may drop audio going to the second unit, and if you wiggle the cable at all you can hear it losing the connection. There is not an alternative connector. Sometimes the speaker will just lose the second unit. I'd return it if I hadn't missed the window. There is no way to keep sleep mode off. Some people suggested just always playing audio at a tone you cant hear but that feels very impractical and not a real solution.
