The passive version of this speaker was measured and reviewed here: https://www.audiosciencereview.com/...ontrol-x-review-indoor-outdoor-speaker.24852/
I noticed JBL made a wireless version of this speaker and thought it would be interesting to measure. It is now discontinued, but it was $499 for a pair. Using the method here by @napilopez, I conducted quasi-anechoic measurements and generated the spinorama data.
Measurements were taken at 1m with about a 6ms gate providing resolution to 176hz. The remaining response was spliced in from hyper near-field measurements after baffle step adjustment. I utilized a minidsp UMIK-1 and REW. I'll include the CEA-2034 data below.
I didn't draw a trend line, but this response looks quite good, just imagine I drew it at 89.4db, just below the 90db line.
Near Field Drivers:
Estimated In-Room Response:
I had already torn everything down when I remembered that @amirm measures distortion at 86db and 96db. My equipment isn't the same, nor are the methodologies identical--still here is distortion at 92db.
Horizontal Directivity:
Vertical Directivity:
This was the first speaker I attempted to measure this way and I picked this one because it basically has Klippel NSF data already (passive version). If you compare the spinorama from Amir's measurement and mine, you see excellent agreement in directivity and frequency response measured past 1khz. JBL included a DSP in this which I would expect mostly accounts for the other differences. You can see the same tweeter fall off and the directivity plots are extremely similar. I've plotted the on-axis from the two versions below:
JBL Control X Wireless Speaker Listening Tests:
I happen to own the passive version of this speaker and use it outdoors with equalization to bring up the bass response. I noticed the wireless version existed and had a boundary compensation switch. This means JBL included a DSP in the Bluetooth version. I was pretty certain they'd adjust the bass response. I found a used set on Ebay for pretty cheap and ordered them. I immediately plugged them in after they arrived and was greeted to solid bass. A quick comparison to the passive version confirmed, JBL had corrected the bass region. The speakers pair with each other wirelessly for stereo over bluetooth or AUX. You can even get two sets and run up to 4 speakers. There is a switch to force mono across the speakers and the aforementioned boundary compensation switch.
The tonality is correct on these and nothing glaring stands out. They don't sound as good as the Revels I have in my primary listening room, but for portable battery powered wireless speakers they are a delight. They are rated 4 hours and you can run them off AC as well. They also get quite loud and easily exceed the volume I'd be comfortable with in a normal backyard situation.
If you're wondering if I'm qualified to venture an opinion--you can read about the two blind listening tests I've conducted here and here.
