The JBL Quantum 800 has acceptable imaging. The weighted group delay has a little bump in the low bass range, but otherwise, everything is below the audibility threshold, ensuring mostly tight bass and transparent treble reproduction. The L/R drivers of our test unit are fairly well-matched in amplitude and frequency response as well. However, there’s a large phase mismatch between the L/R drivers of our test unit, and while it isn’t very noticeable with real-life content, it could have a small negative effect on the stereo image and how objects are oriented spatially. That being said, these results are only valid for our unit, and yours may perform differently.
