Mismatched Powered Subs


Recommended Posts

  • Members

Just found out that one of two house PA subs is in the shop. They normally have a pair of Yorkville LS720P 15" powered subs. At this late time, the only sub we can get to replace the 15" LS720P is the 2/10" LS700. There is only one EQ (on the house Powermax board) and no crossover at the venue. Top speakers are Yorkville Elite 2000s and it appears they are being run full range and the Powermax board is wired in a stereo config.The subs are currently being run mono off the Aux send as an aux fed sub. No crossover is available to us at this time. Power rating of the mismatched Yorkville subs is near identical. This will be used for a 4pc classic rock band with drums fully mic'd for 250-300 people.

 

Wondering if we should use the 2X10" sub in place of the missing 1X15" as we expect a big crowd/full room tonight? If so, wondering what kind of problems we may expect, phasing, weird delays, etc.

 

Thanks guys!!!
