Leafs, the 80 is a 3 way design.It has an aluminum dome tweeter,kevlar mid driver and a ? bass driver.I believe both are 7 inch.It has 2 sets of posts which I use with MIT T-2 biwires.I got into Paradigm early in my addiction and I had a 100% trade up on them(1 year) I started with the Titans then gradually over 3 years ended up with the 80's.I considered going next with the flagship 100's but I thought the bass would be too much for my room.The 80's are very smooth with terrific bass.They play nice and loud with my 30 wpc Aleph-3.They list for $1700.I got mine for $1000/floor demos.I think my system has gotten to a level where I should consider better speakers but I also want a new cartridge,conditioner,amp stand,power cords,CDP etc,etc..... fun hobby,huh!??
