Hey, i have done some searching and found good info on these, but i want to know more. Anyone have specs on the series? K, O, A, etc? Are they similar in design with just larger power handling as you go up the series? I am looking at these and wondering if an O is worth the extra money if i am only pushing 300 to 400rms. Any info on these would be great. I have heard that they are a great sub for the money.

 
Pretty good sub for the money, I used to own a pair of O's.

Nice SQ and decent output. 300-400wrms should be fine.

They were recommended as a sealed box sub only IIRC.

 
The O's weren't only sealed box subs, IIRC they really liked IB setups as well (infinite baffle). Not designed for ported however.

As far as the differences in the series. The K was a great budget subwoofer, sounded decent and had pretty good output. The O's had slightly more output than the K's but were really designed with SQ in mind. The A series was the top line, had more output than both and similar SQ to the O....depends on who you talk to which sounded better.

I had an A for a long time and loved it. Heard some K setups and thought they were great for the money, but didn't compare to the A series.

If you find a 15 A be a bit careful with power because there were some issues with the T-joint breaking. I had one and never had a problem with it, but I never put too much power to it, and I ran it ported (limited excursion in most cases), so take that for what it's worth.

So the K's were nothing special then? I have heard that they were really nice.
