Re: 4x12 cabinet powered by 15W head?
you could do it but more watts is betta for more dynamics
also, 412 is annoying cause it dont fit in small cars like a toyota corrolla, and you can hurt ur back cause its so big and bulky
The amount of force placed on your back under certain conditions can be surprising. Anytime you bend or lean over to pick something up, you put tremendous pressure on your lower back.
To demonstrate this, think of your back as a lever. With the fulcrum in the center of the lever, how many pounds would it take to lift a ten pound object?
When you add in the 105 pounds of the average human upper torso, you see that lifting a ten pound object actually puts 1,150 pounds of pressure on the lower back. In my line of work I have seen A TON of serious low back injuries. I lift correctly and use a back brace when lifting this bulky item. More than one million workers suffer back injuries account annually, and these account for one in five workplace injuries (Bureau of Labor Statistics). 80% of these injuries are to the low back (lumbar spine). Back injuries cost the US economy billions of dollars each year. I am glad I do not have one, I would settle for a little less or more tone with neodymium speakers; I just want to avoid getting any back injury
MINIMIZING RISKS is why I want speakers that weigh 15 pounds less
