Harmon Kardon Onyx Studio the original one. Bought mine 2013 refurbished on eBay and it’s still going. Bought a replacement battery and it was super easy to replace.

I’ve wondered the same thing. Even small Bluetooth speakers were always stereo originally. If you remember, the first few generations of the HK Onyx Studio, JBL Charge, JBL Flip, etc., were all stereo, then suddenly everything was mono. I can understand it for the very smallest speakers - Bose Micro, Tribit Micro, JBL Go, etc. - it wouldn’t make sense to try to cram dual speakers into those tiny housings or to try to create stereo sound in such a small space, but with the rest of them, I don’t get it. The only thing I can think of is the ‘race for the bass.’ After a while, it evolved to where all anyone cared about was ‘how much bass is there?’ and if companies could cram 1 large woofer into the same space that had once held 2, or even 4, smaller speakers, they could produce much more bass. The other possibility, as someone suggested when I asked basically the same question on another post a couple of weeks ago, is so that companies can now force you to buy 2 speakers instead of 1 if you want stereo sound.

HK Onyk Studio should be good for you. It has a battery, good bass, fun to watch movies, and captures the sound of the atmosphere completely. When placing it, you don't have to place it next to your macbook. You can place it anywhere. The sound will jump onto the screen itself. Another thing is that listening to music is beautiful too.

Yeah, both the HK Go+Play and Onyx Studio series would blow away the Max. They are my go-to speakers when I want the music to really shine through. Incredibly deep bass and crystal clear mids and highs. None of my other 5 portable Bluetooth speakers come close. Edit - Just saw someone post the HK Go+Play 3 is selling on ebay for $132 right now. At that price, it's a no brainer.

The Onyx Studio series is in a class of its own. It’s the loudest most clear sounding bass portable Bluetooth speaker you can get at that price. I sold all my other “boombox” speakers and kept the Onyx. The Luna is nice, but it’s not in the same category. You’d need like 4 of them to match the Onyx.

My Onyx Studio is the best sounding speaker I have. Guarantee it blows away the JBL. You won’t find a better speaker than the Onyx unless you get something in the $600+ range.

If you're "upgrading", go to the next level.. not the same speaker in a different housing. Look for a used HK Studio Onyx. Pick the style you like the look of and hear your music in a truly upgraded fashion. Even the 10-15 year old ones still sound awesome. The HK Go+Play series is just as good too. Either one will blow you away over what you had.
