Hi guys. I am going to "test" my new PA speakers I bought by providing the sound for our neighborhood new-year party. it will be at a small open manual car-wash and the street infront, so my 2x 120dB(z) peak (line source) mains should easily take care. problem is they are made to be crossed at 100Hz or above, so I need a sub. my sub is not a PA sub though. it is prety strong though, in my room at least (using it in 3 o'clock position). I don't expect it to make a full PA subwoofer cause it is obviously not made for this (Kef Kube 12b). since it is rated 114dB max it should at least give me some bass though, so I hope. I also pretend to use the frontwall to add some gain. Now I see some problems beforehand and kindly ask here because I know that a lot of users here have advanced tecnical knowledge:
1) Is this a bad idea? can I damage my sub by playing it at it's limit? (I obviously will be very carefully increasing the volume)
2) the sub plays very deep (rated 22Hz and goes much deeper with room gain) and is sealed. should I use a highpass? at 30Hz-ish or higher?
3) does the low-pass point make any diference?
4) a nother option would be using my 2 old KRK Rokit 8's to provide the/some bass (would be lowpassing them at 100Hz)
