What would be a good crossover point for a 5.25 in infinity kappa perferct component system. I am running a JBL 300.4, i currently have kappa perferct 5.1 components for the fronts in Q-logic kick pannels. In the rear i have a pair of infinity kappa 6 by 9's and i have 2 kappa perferct vq 12's in a sealed box, (each chamber is 1.5 cubic feet) each running off a infinity 311a, thanks for the input.

You mean for a HP filter? What's your LP for your sub? ------------- Support the12volt.com

An ideal setup has the subwoofer LP and the mains HP set at the same frequency and slope. ------------- Support the12volt.com

Ok, i understand this is the ideal setup, but will thoes components be able to handle 90 hz without possibly damaging them? I usually listen at a fairly loud level, when i am listening at this level i am worried about damaging the woofers, specifically in the 5.25 components. Thanks

I'd say you can run down as low as 90Hz with no issues.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Thanks or the information. i have made a donation to this site as i know how much it costs to operate something like this. This site is full of great information, hopefully it is around for a long time to come. Also what do you think of the jbl 300.4?
