Hi John
Was going for the 8.4 but went for the 1800 watt as Chris said he likes the electros and i had electros in my old Express which i like over Lambs....Did have a Elite built with 2 x 1800 watts electros before i bought the Enforcer but Chris sold it. Its along story..
The new Express over my older one is a breeze, its like a bag of shopping lol
