JBL K2 5500 anyone?

35hz is very good responce, sure many claim lower but at what SPL and level of distortion? And what type of music are you into thats sub 35hz anyway? Heck most HT effects are lucky to be this low today. The older movies sure. But today producers know most use HT in a box and 40hz is about it for those.

Anton,Beware of backroom deals,you will usually get burned.I would be very wary buying from someone that would not let me try something out.BTW,35Hz is a very respectable measurement for a speaker and JBL is usually spot-on with their numbers.

Despite the above 2 comments, 35hz is not very low for a full-range speaker, especially at that price point, IMO. Its high enough to make me lose interest, at least at this point. And yes, there are many movies and CDs that go below 35hz without blasting, depending upon the quality of your system.

I don't think the 35 Hz will be a brick wall. There is sure to be plenty of energy below 35 Hz. I do not think it is wise to dismiss a world class speaker on this measure alone, unless, like most people, you prefer the North American consumer slow resonant deep impressive bass extension over fast bass with better transients and lower distortion.

Good quality bass below 35 Hz is actually extremely expensive to engineer in significant SPL's. It is not crazy but actually quite reasonable to use a dedicted high quality sub for this task.

Shadorne - you raise a good point. Not sure about the 5500s. but the K2 9900s I heard at RMAF were pretty impressive.

Antonkk - You won't really know anything until you try them in your system and you may very well love them, if they are in good condition. I would be wary if the seller won't let you try them first. Depending upon the price, maybe you could offer to pay a small amount to be credited towards the purchase price if you decided to buy them, sort of like the Cable Company does? At least them he could see you are serious and that might change his attitude. Good luck.
