These are 830LR Floor speakers with a high watt rating of 400. They are 8 Ohm speakers at 91DB. There is 1 set of binding posts in the rear. I believe there are 2 6.5" speakers and 1 3" speakers as well as the tweeter that is 1". I Also have another pair of these Audiofile family speakers different model number but al.kst the same speakers. They are chocolate  or black in case you don't like these natural color. The boxes are made very nice and are in perfect shape. These cost uowards of lioe $1200 brand new. I Inherited them so since I didn't pay full retail I don't mind selling them at a .much more of a discounted price.
