Not sure if it was all due to form factor or not, but I had a GK Backline 1-15 that someone gave me when they were moving. Super heavy and not that loud. I used it for a practice amp, but it was not gig worthy (for any gig) for sound, weight or power. It ended up scrapped.
I like the form factor but don't believe it is optimal for weight/volume/porting/sound (IMHO only)
