B&C 18PZB100 18" Woofer
B&C 18PZB100 18" Woofer is rated 4.6667 out of 5 by 3.
Rated 5 out of 5 by from What took me so long!Replaced Celestion FTR18-4080FD 18" Professional Cast Frame Speaker 1,000W which was housed in the B52 horn loaded cabinets. The specs on the Celestion are lower than the B&C's. The PZB100 really have a warm and pleasant tone too them. Never bottomed out. I tried to push them a little more and it just laughed at my crown xti2000. To be even more honest....I don't think my cabinets can handle this driver. If you have horn loaded cabinets, make sure the BL is 25+ and the QT is 30 or less. You won't be disappointed and you will notice the difference.

Rated 5 out of 5 by from Great speaker from a great company!!B&C puts great research and development into all of their products,and the 18PZB100 is an amazing example. I currently use 4 of these in a 11.2 home theater setting, 2 as L/R front channel 3-way mains and 2 as passive subs. Great smooth, powerfull bass response was achieved when introduced to this system. These woofers like an amp with power(as any quality 18 woofer does),and rewards you with a warm sound at low/moderate volume levels and seizmic bass at higher volume levels. Never "harsh" sounding, and always great listening. Best for your dollar in my opinion. I have built many, many loudspeakers over the last 30 years and few can touch B&C quality,sound and very affordable price. I'm a fan for life!

Rated 4 out of 5 by from great driver for bass horn2 of these used in a large (3' x 4' x 6') bass horn loaded to 32hz. Excellent results! Very linear, nicely damped rigid cone handled 1200W RMS without break-up for a limited time.Only complaint is power compression and overheating with very high inputs in a bass horn application, but that is to be expected since the horn allowed only about 2mm peak-peak excursion, depriving the driver of airflow across its coils.

B&C 18PZB100 18" Woofer

Is this a suitable replacement for a yorkville es808 subwoofer? They are originally equipped with rcf l18y800 but it can't seem to find that exact speaker. I am considering purchasing a pair of cabinets that are for sale without woofers.
