I heard several LFSys cabs at the SE Bass Bash. IMO they are worth investigating.
There is no "lack of bottom end". There is plenty of bass but it is tightly controlled which eliminates much of the boom and woolliness you get on many gigs.
For years I humped a 90lb 2x10 and 90lb 1x15 around. Great tone, but way too heavy. In my 40's it was just about doable, then my lower back finally gave out in my 50's, with a herniated disc. Thankfully D class and Neo have kept me in the game. I'm also trying to downsize my basses to around 7lbs.
Looking good, Alex.
Too heavy for my poor old back. I need all my speakers in the smallest package I can find, but looks like a great cab for many bassists.
I don't have any prejudices but I have preferences.
If you're selling a quality 5 string FSO, under 8lbs, burst and tort and a rosewood fret board, then you'll have my attention.
I replaced a 60's Precision pickup which had a weak and lifeless tone, with an 80's Bartolini, which had a huge, warm, fat tone. Same shape totally different sound.
Shape was the only common denominator.
