Hi! First of all, I apologize for making a old post come back to life hahaha.
Now, I've recently purchased one of this cabs. I went to the guitar store with my rig (an Ampeg PF 500 and a Cort Artisan A5 plus) and tested 4 different cabs: this one, a Hartke 410 XL, a HD 410 and a HD 410b.
I really like the 410 format, but all the 4x10 cabs sounded lifeless and without the punchy funky sound that I like. On the other hand, I wasn't expecting too much about the HD 115, mainly because 115's seems too boomy for me, but when I plugged my head into the cab it blew up my mind! Even without the tweeter on, it had a great, focused sound, very versatile and loud as hell!
The same night I played a gig with it, and for the first time a I've more felt the bass than hear the bass. With the tweeter switch on I had the sound that I like (cutting into the mix without losing presence)
