Brand: Seeburg

#23 Seeburg X6: $1,975 Passive Thomann $1,975 eBay

Same family: the Seeburg X1 (smaller model, rated 3.4/5), the Seeburg X2 (smaller model, rated 3.6/5), the Seeburg X4 (smaller model, rated 3.9/5) and the Seeburg X8 (larger model, rated 3.5/5).

Pros: A loud, easy to drive passive coaxial 12 inch PA speaker with consistent sound across its pattern, ideal for bands and venues. Manufacturer measurements give preference scores of 3.07 standalone and 6.04 with an ideal subwoofer, on par with the JBL PRX912. The coaxial 12-inch woofer and 1.4-inch compression driver give a 2.2dB reference band and consistent sound across the 80° x 60° pattern. With 99dB sensitivity and a 131dB peak rating from an 18.5kg cabinet, it suits bands and venues that need output without bulk. Measured bass extension of 80Hz (-3dB).

Cons: Bass reaches 80Hz at -3dB and about 66Hz at -10dB, so a subwoofer is still needed for full-range music. It is passive, so you need an amplifier and a processor with Seeburg presets, or the self-powered X6 dp version. A 4.34 directivity-index deviation means off-axis balance shifts more than the flattest designs here.
