B&C 18PS76 18" Woofer
B&C 18PS76 18" Woofer is rated 4.7143 out of 5 by 7.
Rated 5 out of 5 by from Refined sound at a good price.I bought four of these back in May of 2013. Just finished some boxes for them. These speakers surpassed my expectations. They measure very similar to each other and have a quiet suspension system even passed x-max. I run a pair per side off a Crest 7001. The box is 7.5ft per driver and tuned in the low 30's. I run them up to 300hz with no degradation in sound quality which was what I was hoping for in a light coned 18".B&C has impressed me with their quality and cosistency. I'll be looking at the more extreme options when funds permit for a sub 100hz system.

Rated 4 out of 5 by from Great sub, but just killed itI've had this speaker for about 9 months. I did a low frequency test on it and she blew. It was good, but is dead. I hope there is a warranty on this driver.

Rated 4 out of 5 by from Good replacement 18!Bought these as an alternative to other similarly priced 18s that I have been using in my small PA. The 18PS76 is very clean and detailed. Transient response was excellent. I was also impressed by the quality of the machining. This driver exceeded my expectations of a 3"vc driver. Additionally, the band raved all night about the improvement in the low end. I plan to put more of these drivers into service asap. Highly recommended.

Rated 5 out of 5 by from Best in price range, killer performanceI normally use Eminence or Dayton 18's in my audio company. After replacing a blown Eminence Omega with this B & C driver I will buy nothing else in this wattage and price range. Amazing value!

Rated 5 out of 5 by from Cannot kill this thingWe ran 10,000 of Crown power to this thing and it laughed at us. We then ran a 22 hertz signal to this woofer and we thought it was gonna vibrate its self out of the sealed enclosure we built but nothing happened besides maybe some foundation damage in the basement.

True RMS ratings?

I just received this speaker today, and I put it in an enclosure I already had, gave it 450W max (8 Ohms) with a Behringer iNuke3000DSP. I smelled the voice coil burning. I have an MCM 18" rated at 300W RMS and 600W Peak (8 Ohms), and give it max power one channel can give from the same amp. I never smelled the voice coil burn from that cheap Chinese speaker. I find this hard to believe, but did B&C over rate their speaker by just about 4 times...? Saying its "600W RMS, 1200W Continuous Program".
Asked by: Lewis C
Well - if you smell a burning voice coil - that usually means the speaker is damaged and will stop working. The magnet and VC get very hot. You might have smelled the paints and other coatings experiencing heat for the first time. If the speaker still works and there is no scraping - the voice coil is fine. As for power ratings. A 600 watt amp rarely outputs that much power constantly. And at 99db 1W/1M, you only need 100 watts to reach 105db. Amps often "peak" at 10 times their ratings but that is for milliseconds. Make sure the cabinet volume and ports are matched for the speaker - and I am not sure what you mean by "giving it max power". What was the source? How are you rating the output? These things may help and you may be expecting more than a single 18" driver can deliver.

Optimum ported enclosure size

Hi what's the optimum ported enclosure size for max output from 40hz up? There is no info anywhere online for a recommended enclosure for this driver. Plugging it in to winisd I get a weird box size of 1.9 cu ft tuned to 58hz which can't be right. I'm guessing it it needs about 4-5 cu ft tuned to 40-45hz. Thanks anyone!
Asked by: Kyle
WinISD is actually correct with the modeled size they are providing you. The very low Qts and high Vas on this woofer means it is ideal for small ported enclosures, although compromises will have to be made in order for it to acually fit in an average sized box. If you are interested in 40 Hz and up, I would recommend 4.4 cubic feet total. Three 4" diameter ports that are 12" long each will tune the box right at 40 Hz. Make sure you apply a high pass filter at 35 Hz for the best protection. I recommend lining 3 of the 5 interior walls with foam or fiberglass insulation for best results.
