From best to worst 1. Soundcore motion + 2. Klipsch nashville 3. Sony ult field 5 & tribit stormbox lava (tie) 4. Marshall emberton 3 & Bose soundlink flex 2 (tie) 5. Kef muo 6.tribit stormbox blast (OG) & Earfun uboom x(tie) 7. Soundcore boom 2 & x600 8. Harman kardon onyx studio 6 9. UE everboom, wonder boom & epicboom Soundcore motion + has been discontinued and has no ip dust rating Klipsch nashville, kef muo, bose soundlink flex 2, and harman kardon onyx studio 6 are mono format speakers Sony ult field 5, tribit stormbox lava & blast, earfun u boom x, Soundcore boom 2 & x600, UE epicboom and HK onyx studio 6 are all pretty large. The Marshall emberton 3, UE everboom & epic boom are 360⁰ speakers this is subjectively worse than a forward firing speaker for soundquality.

Hey! I had onyx studio 6 but tore the subwoofer and all passive radiators ahahaha. I'm planning to buy harman kardon luna. Could you tell me the difference between these too? Like is the sound stage the exact same and the only difference is bass and bass depth? How deep and thick bass is on luna? Onyx studio 6 had window shaking bass and it was mind bowling how deep and strong it goes (35hz).

hands down onyx 9. proper deep rumble at 30hz. it as a big bass peak at 52ish hz and a secondary peak at 34hz. I had onyx 6 for years and recently got onyx 9. both of these are like a subwoofer when you place the right. they even have proper deep bass even at 10% volume.

I have both and honestly they sound pretty similar, mainly just a different in size. The tuning feels almost the same. If you want deep room shaking bass, go for Onyx 6, at the cost of some portability but Onyx 6 isn’t bad to carry around either. The handle is great. I love my Onyx 6 but I end up using the Luna more since it’s smaller and still has surprisingly solid bass for its size. Obviously it can’t match the Onyx 6 in volume or room filling sound, but up close on my desk it sounds great

I have bought the Harmon/Kardon Studio 6, twice because overall it has quality bass and highs, it goes loud but not too loud. And the sound quality is always wonderful. It’s round and has a handle making it perfect for on the go.

Both sound excellent and best in their class, but between the two, I’d choose the Onyx 6 for its form factor. I don’t like the newer weird round shaped ones. You can’t go wrong with either one.

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.

I constantly see the HK G+P recommended here and after using one, I understand why. It’s a beast. Only matched by their Onyx Studio series. I hardly ever see any Sony recommendations.
