How do I get a speaker with the bass slam of my el cheapo ear buds...?


You know, the ear buds that come free with a Samsung smart phone. Was just listening to Brooks and Dunn’s My Maria over my Galaxy S8 and ear buds, and there is a nice drum track in there and it was nice, deep, slam to it. But if I connect the phone to my stereo system via analog inputs, I don’t get that slam. Do they boost the bass in these ear buds, or is my audio system not delivering the bass as it should?

Oh, and I also connected my phone to my car system via the AUX input and I don't get that kind of bass in the car either.

Your speakers aren't the problem.  What are you using for amplification?  Have you considered adding a subwoofer (or better yet two)?
I'm using a PS Audio Stellar Gain Pre/DAC into a Krell FPB 400cx power amp.  With regard to subs, I've heard smaller speakers than mine produce more of the impact that I'm looking for.  Perhaps it's just that my speakers are so old.  Actually, the amp is old too!  My equipment is like me!
That amp is a beast and your speakers should be able to dig pretty deep.  I'm surprised you're not getting the bass response you'd like.
Oh, they go deep.  It's just the initial "hit" or attack of a kick drum, and the like, that I am questioning.  The Signature IIs are sealed, not ported, and I wonder if that has anything to do with it.  They also have the old poly mid drivers and bass woofers, which I assume are not as fast as modern drivers.
So, afterall, you want to let the phone to drive a series of state of the art preamp, amp and speakers and get a nice slam effect like the phone drivig a free earbud.  Thank you very much for your experiment.  It showed to all of us that it does not work.  :)
