    Hey guys just need a little problem sorted and i guess this is a good place to get help!

    so my band uses a fairly small rig for pub gigs, a set of dynacord a151 and a152's we use a yamaha mixer and eq compression and all that stuff oh and a yamaha poweramp...now the thing is these speakers supposedly have a built in crossover (correct me if im wrong) but for some reason the low signals and high signals are coming out of tops and bins!...and that CANT be good for the speakers :P. what could be wrong lads and lassies?

    Look at the inputs at the back of the speakers. Normally if speakers have passive crossovers, there'll be an input, and an output labelled as the top output or something similar. It's possible they don't have crossovers.

    It's very easy to check, screw out the plate with the speakon connectors, you should see a capacitor (Cylinder shaped), and some square long white resistors. If those are there, there's a crossover. If it goes directly to the speakers, you'll need to get a separate setup.

    Operator error, most likely. The crossover is located in the subs, so you must run signal from the Poweramp to the A151 subwoofer then (and only then) to the A152 tops.

    If you do it via the tops first then yes, you will be sending all frequencies to all speakers and will burn a driver out sooner rather than later.

    Bear in mind the Passive crossover of the A151 is set pretty high at 300Hz (far higher than it should be IMHO - 80-150Hz would be more in line with current trends). High crossover points seem to be something of a thing with Dynacord in particular, no idea why.

    You will get a lot of other stuff going to your subs with such a high crossover, guitars etc, maybe even the bottom end of a deeper Male Vocal.

    The lo-frequency range can be extended powerful via the integrated passive crossover network (300 Hz -12dB/oct.), allowing easy connection in parallel to existing fullrange or mid/hi cabinets.
