ok say if i run these horns

http://www.parts-express.com/pe/showdetl.cfm?Partnumber=264-204

says xover point is 500hz 12 dB/octave so if i run a pair of these and bridge 2 of the channels on my zx850.4 to make it run at 4ohms and the horns are 8ohms so i would run them together to make them run at 4ohms so its easier to get power than 8ohms

heres the problem my xover on my amp only goes to 200hz the xover point on the horn says 400-9khz so i would need a inline xover to prevent freq's going to the horn that are lower than 400 right, well what about freqs about 9khz will they hurt the horn or no.

so if i run the two together at 4ohms should i connect a xover on each horn and get the one made to run at 8ohms and block feqs 0-600hz @8ohms and 0-1.2khz at 4ohms, what load will each horn be seeing and will these xovers work and prevent low freqs going to them, also only rated for 150rms the xover is well i plan to give 125-150rms per horn so i would have to use two correct, also the xover on the horn is at 12db octave and the xover is at 6db octave whats the difference

lol @ responses

I think your best bet would be to either trade your amplifier or get a head unit that's capable of running these actively. Those "bass blocker" crossovers aren't exactly high quality and installing them defeats the purpose of going active. Let us know how your horn setup turns out - I'd like to do one in my next install.

Also, you won't need anywhere near 150 wRMS to get horns screaming. They're extremely efficient. You can read about the difference on xover slopes at bcae1.com

well i wont be using these in my truck they are for my boat to have on them on the lake and out at boca basically tower speakers but much cheaper and i will have 6 1/2's for mids and then 12's for the subs just need somethign extremely loud for vocals like these horns

so those blockers i am hoping will do the trick

best place to ask about horns like that and if your lucky not get flamed is over at diyma. imo that's not going to work like u think.

why wouldnt it work like i think i have friends of mine who have them in their trucks in the hood and it gets really loud and doesnt sound all that bad and they have no clue what they are doing
