A reliable 18" cast frame replacement subwoofer speaker that delivers all the low-end you need.

The 18-220S 18" Cast Frame Subwoofer Speaker is built to engineering perfection using the most innovative design concepts and materials. B-52 transducers are manufactured to maximum tolerances by some of the most well-respected engineers in the world. All loudspeakers are subjected to a wide array of quality-assurance tests during and post assembly. It's for these reasons that B-52 speakers typically have a 0.2% return rate and are backed by a five-year warranty.

  • Multi-layer, precision-wound polyamide voice coils create superior electro-mechanical energy conversion
  • Rigid, heat dissipating cast-aluminum or steel frames provide ultimate motor structure support
  • Deep, bumped back plates allow the voice coil to reach maximum excursion without bottoming-out, resulting in deep bass
  • Advanced cone materials with superior internal damping mean ultra-fast transient response and super-low distortion
  • Tough, flexible surround with long-throw, positive-roll design, control extreme cone excursion and is highly tear-resistant
  • Vented pole piece pumps air through the magnetic gap and directly over and around the voice-coil

Comments about B-52 18-220S 18" 1000W Cast Frame Subwoofer Speaker:

Electronic engineer doing a pro sound upgrade on a pair of EV Eliminator subs to increase handling from 400 to 1000 watts. The 18-220S CAN be made to fit but requires modding the cabinet a little to fit it in. This driver takes a little more Vas volume than many but works well in the Eliminator. Good venting to the motor, uses spring-loaded connections for the wires which seem to hold the wire well and be effective. Could hold 12 and maybe 10 gauge. I pushed these with 900 watt bridged QSC amps till clipping with no bottoming out or distortion. You will like their sound. Overall nicely made, BUT the mounting flange seems to be a potential weak spot for bending and the basket struts are just flat bars of aluminum with no ribbing or other structure and I worry about flexure. Still, for the price, I am very pleased.

Documentation a sore spot for me as I had to call B-52 to get basic engineering data, such as power handling: EIA, AES, continuous, peak? They don't know. Bottom end of driver good to about 30 Hz. Don't expect it to go much below 25 Hz. About 90dB/w/m at 30 cycles. Xmax = 6mm. Freq. Res. about 30 Hz. Inductance about 2mh at 1k. DC resistance 5.4 ohms. Vas = 255 liters or 9 cubic feet. Frame 18.2" Depth a hair over 8 inches. Minimum Impedance about 6 ohms at around 160 Hz.

MY REAL COMPLAINT with this driver wasn't the driver itself but the scant packaging. All they put in the box is two thin strips of styrofoam underneath and Both of my drivers arrived up out of the one piece with it under the cone and one had the foam pushed through the wrapper into the cone and the flange was bent. There was no sign of rough handling or abuse in shipping. If B-52 only put a wrap of tape around the driver and foam to hold all together or just added a foam piece around the magnet, these drivers wouldn't be flopping all over the place inside their boxes during handling! MF came through for me and overnighted a replacement. My recommendation: if you buy these and really want to be sure in a critical app, get them to open the boxes, inspect the drivers, and pack some additional material in there to protect them, even if it costs you a little extra, especially if you really NEED them in a timely fashion as I did and cannot afford delays. With that all said, these appear to be great sounding drivers that should work well for many years and I got a pair of them delivered for a great price well below the competition. That was a real bargain in my book and all the alternatives looked to have cost a LOT more. Recommended.

Earth Shaking Bass!

By Brian Frook

from Daytona Beach

Comments about B-52 18-220S 18" 1000W Cast Frame Subwoofer Speaker:

I was very happy to see that this driver can really dish out the bass. I did SPL test measurements and with a 6 Cu/Ft cabinet using an "L" slot-style port, I was able to get 18Hz - 100Hz +/-3db with low frequencies extending to 10Hz - 150Hz (+/-12db). The only complaint was the shipping container that B-52 uses for these drivers. However, it is built so strong that even if it rattles around in its box during shipping, it will not suffer any damage. Amp used for testing was a Samson SX-1800 (1,200 W/Bridged RMS) & Behringer Ultragraph FBQ-PRO FBQ1502 EQ/Crossover.

these speakers rock!!

Comments about B-52 18-220S 18" 1000W Cast Frame Subwoofer Speaker:

B-52 18-220S 18" 1000W Cast Frame Subwoofer we bought a pair of these to supplement our system and wound up using them as our primary subs. they deliver chest pounding lows without effort, are extremely well built and very efficient. if you are looking for an 18" to upgrade your system this is the speaker for you.we are replacing all our 18's with these and the price is right. the only drawback is they will add some weight to the cabinet but well worth the extra muscle to move them. get yourself some before they figure out how good they really are and raise the price.
