#22 Seeburg K20: $1,969.00 Passive Thomann $1,969.00 eBay

Pros: A loud passive PA speaker with two 10 inch woofers and a large compression driver, suited to installs paired with a subwoofer. Dual 10-inch woofers and a 1.4-inch compression driver reach 134dB in a 22.5kg cabinet. Predicted in-room smoothness is a solid 0.711, and vendor Spinorama data gives preference scores of 3.14 standalone and 6.61 with an ideal subwoofer. Measured bass extension of 95Hz (-3dB).

Cons: Bass reaches only about 95Hz (-3dB) and on-axis narrow-band deviation is 0.562, so the response is uneven and thin without a subwoofer. It is passive, so an external amplifier and processor are needed, and pricing is high for the class.

Is the Seeburg K20 right for you?

Skip it if

  • you will not add a subwoofer: bass rolls off below about 95 Hz.
  • you want the best value: the higher-rated QSC K10.2 costs about $1,169 less.
