UBoom X - 950 firmware TWS demo (Patreon)

I finally found some time to try out my 950 firmware with 2 units playing in stereo compared to a single unit with 949 firmware and my old home speakers which I had bought back in the 90s and used them as my main speakers for many years.

950 firmware is optimised for TWS use to get a more natural balance closer to the sound of 2 neutral speakers when 2 Uboom X are connected for stereo, unlike 048 and 949 where a single Uboom X is tuned to sound more similar to a stereo setup. Without additional adjustment the balance will change with 2 speakers playing compared to a single speaker with a more bassy sound with less clarity especially when listening indoors.

Unfortunately there is no way to directly tune 2 speakers connected for stereo, therefore I had to base my adjustments on measurements done with 2 units and then prepare a new firmware with the necessary corrections applied.

I think the result is pretty convincing. IMO 2 UBoom X in stereo sound way more natural than my old "Hifi"-speakers, 2 UBoom X with 950 sound pretty similar to a single unit with 949. Although the result could be probably improved even more but due to the strong interference between 2 tweeters being so close to each other, you can only create some average response which will change a lot depending on the listening position. Because of this I would suggest to place the speakers upright for TWS use if you intend to get a more constant sound within your listening window and then adjust your listening height and try to remain more or less constant.

Here you can find the playlist with all tracks used in the video so that you can compare my recording of the speakers to the original music to get a better idea about the actual rendering.
