Amazon, and many other high to low consumer products, over do bass too.
It is not an Apple problem but an early 21st music production, speaker manufacturing, and marketing problem. I blame Bose and booming car audio for causing it at all.
My various Amazon Echos suck for all but the
right kind of music. For voice, like NPR or whatever, it is painful and booming to listen to. I send my kitchen Echo Show 5 (an atrocity of audio) to a small BT speaker just to listen to anything on it. If the Show was not so damn convenient to watch TV on via FireTV Recast in my too small kitchen, I would have relegated it to the guest room long ago.
I am looking forward to the day when, speaker engineers design these smart speakers and the like, with all types of music in mind and give the user a way to adjust the horrible default barf noise setting.
Regardless, this Apple speaker is no longer made but, they are coming out with a replacement. The Mini is the current Siri speaker model and is probably a better bang for the buck anyway at $99 in USA. Even less at Costco.
If you are not an Apple home, just skip them. I am but, am in too deep with Alexa. For now.
