soundcore - Select Pro

I'd most definitely have to say the Soundcore Boom 2 Plus for sure. I got mine for around $175 on a sale. By far my most boomy and loud portable speaker. I have the Soundcore Select Pro, Boom 2, and the Boom 2 Plus. You will not be disappointed with any soundcore you choose, I assure you. There are some Amazing Reddit pages dedicated to Equalizer setups that make it even more impressive. Feel free to reach out if you need links

Get a bigger speaker if you want "sub bass". I have a Motion + and it is great for it's size but not going to thump any sub woofer frequencies. The Soundcore Motion Boom/Select Pro put out much better bass. (I have a Mifa Wildbox that is very similar the soundcore Motion Boom in bass output). Had a few of the Soundcore Booms and they had great bass but it did not extend into the sub-bass region. Eons ago I had a compact Doss XL that Oluv was a big fan of and it had amazing low bass for the size but developed some rattles at high output and now living at work. I had heavyass Tribit Blast that could really rumble but at 12lbs was not that "portable". (Almost too much bass indoors !) Gave the Tribit Blast to a friend and going to try out the newer & cheaper and lighter Earfun Uboom X. Might want to check out the Harmon Kardon Studio speakers if you like the HIFI sound and from my memory did a grat job with sub-bass. I never grabbed a Uboom L because I had Motion + but I think most reviewers thought the bass was better and more extended on the U-boom L.
