TasDom Posted October 31, 2013 Posted October 31, 2013 I want to replace my RW12D's and I've been toying with the idea of using my KP450 LF sections. I know I'll need an external amp but other than that, what do you think would be needed to get the most out of these? They are dual 15" with 4 ports on the bottom front........thoughts? Thanks! Quote
CECAA850 Posted October 31, 2013 Posted October 31, 2013 What application, HT, music? Do you know the Fs of the box? Quote
TasDom Posted October 31, 2013 Author Posted October 31, 2013 What application, HT, music? Do you know the Fs of the box? Mainly HT. This is all the info I have: Quote
CECAA850 Posted October 31, 2013 Posted October 31, 2013 Looks like they drop off like a rock at 50Hz. OK for music, no good for HT LFE duty. Quote

Scrappydue Posted October 31, 2013 Posted October 31, 2013 tas you can build a single 18 that i have for like 400 then you could buy an amp that would power 2 like the inuke 3000 dsp then just build another 18 down the road. even a single one should destroy the pair you have now. Quote
Pete H Posted October 31, 2013 Posted October 31, 2013 Great question and I'm asking the same one about the K48's for a similar project. I don't think you can answer that without the specs on the driver and I just sent Trey a PM asking for mine because I can't get a response on my post, but I'm doing it for audio only so we're looking for two different results.

If the cab would work I might try to upgrade or modify and thx btw Carl for your input It's the tuning of the cabinet. The problem is, the driver and cab are designed to work together. If you lower the tuning frequency of the cabinet, the driver may damage itself reaching the lower notes (over excursion). 1 Quote

These cabs are really cool and was just kicking around the idea. Appreciate it! Quote
Pete H Posted October 31, 2013 Posted October 31, 2013 Sure, I'll just put them next to my K34's, the K48's the Kappalite's and the cast 15's I have from Bob. The last thing I need is more 15's, I just need to get all of the ones that I have in their permanent resting place. Quote
