The JBL GT5-S12 was not really thumping on this wooden room but when on concrete it absolutely destroys my chest

About 4 ohms 300w rms at 1200w peak

Made of Thick cardboard with internal bracing

Using oily glue (Cyanoacrylate) to hold the structure and B-7000 (adhesive glue) in help to keep it intact and seal, layered with a waste of eletrical tape for water protection IV and acting as a double seal.

Battery: 12.6v 6Ah (cuts the wattage yes, to low voltage)

Drivers: Dual 3 inch Long throw 15w - 20w rms Woofers 4 ohm and dual 1 inch high sensitivity tweeters of 15w 4 ohm (quite overpowering the woofers)
