Alternative to Hartke stack too heavy

[Brocky]

Hello, I play for 10 years on Hartke stack: Ha3500+410XL+115XL. I like its power and sound: with my 5 string bass, the B sounds really good. BUT it's too heavy for my back (more than 40kg for the 410)... I also own a Yamaha Bass Stage 250 but it's not OK with 5 string and it's heavy too: 34kg...
So I'd like advice for a new amp which is lighter because I've several rehearsals a week and moreover my studio is upstairs.
I thought about Markbass but I'm not sure it's deep enough: I really love low frequencies

Everyone has their own preferences on gear, so your choice will come down to what you want.

For me I would be looking at a fEARful 12/6 and something like the new PF-800, or a GK MB800.

I would look into finding lighter cabs. I recommend you look in to:

Barefaced Bass
fEARful
fEARless/greenboy cabs

Barefaced might be a great option for you. They are UK based, and sound great.
