in waht instance would i need a crossover if i built a cab or put speakers in an empty one?
You should use a crossover anytime you have different drivers for different frequency ranges.
so if i bought two of the same speakers and loaded them in a cab
sme model specs etc it wouldnt need a crossover
there are 2 types of crossovers
active crossovers which are available alone or as part of an amp. they split the signal by frequency. the seperate signals then get sent to seperate power amps and speakers.
passive crossovers are used inside cabinets. they take the signal from a power amp and split the signal by frequency to be sent to different drivers in the cabinet. Two way crossovers are used in cabinets with one or more of the same diameter speaker (10's,12's 15's etc.) and a smaller size driver or a horn. Some cabs have 3 way passive crossovers to send lows to one speaker (like a 15), mids to another speaker (like a 6), and highs to another (like a horn tweeter).
As long as youre using one type of speaker in your cab (liek two 10" drivers) you don't need a crossover.
thank you! fror the help
My experience with PA sound is that subs with crossovers sound cleaner - no mud. I would assume similar with bass cabs. Also speakers can be damaged by sending the frequencies our of the speakers range.
