EAW KF850 Cabinet Maintenance 

I have the sb250s too, but the z Version and they use b&c speakers, really good too

Hi Ken, nice to meet you! I have 12 kf850-T and 12 Sb850 ... I have two qestions!! I use In my Sb850 RCF L18P300 and In the KF 850 use RCF L15-554-k , RCF L10-YK , JBL 2" for highs... this configuration is correct? and... What amplifiers you recomended for this system? I use LAB gruppen LAB 1300C For Highs, LAB 1600 For MIDS and LAB 2002 for LOWs... next i use FP 6400 for sub and MX800I to controll. What you think about?

@@gonnmeizoso2911 That all sounds like they are not real EAW parts (EAW mostly used Simi-custom drivers with EAW part numbers not RCF part numbers) but what you have should be good, they will how ever not be useable with EAW crossover presets as they will not have the same acoustic performance. You will need to do measurements with Smaart or similar test equipment to set up proper crossover settings. I do not think the MX800i will let you change the settings so I suggest using a modern DSP based unit like the Lake. Good luck.

Yeah, pretty much sacrilege putting Eminence in there. If you are burning rcf. You will definitely be replacing those again, & often.

RCF cone kits may not be available.

@@solitaire5142 so buy another rcf driver … why eminence …. Obviously eaw thought rcf drivers are better or they would have loaded the speaker with eminence…

+Stevie West EAW has used an assortment of drivers from RCF, B&C, Eighteen Sound, and yes, Eminence, throughout the years. Until you hear a box where the drivers have been replaced with the Eminence drivers (the specific ones used in the video are designed as replacements specifically for the KF850, not repurposed off-the-shelf units) then you won't know for sure. The quality and all-around level of Eminence products has improved greatly over the years. I still like the Italian drivers, but there's nothing special in the water there, just a brain-trust of knowledgeable driver engineers that have moved around among the Italian driver manufactuers spreading their competency around to the products made by those mfg's. The only thing I saw in the video above that made me cringe slightly is the modification of the old-style midrange phase plug, which will definitely modify the sound of the box.

@Stevie, I own a few KF850's and I have replaced some with Eminence, I can assure you that I would prefer to use the RCF drivers, however I decided to take a chance with the Eminence and they sound just about the same.

rcf l18p300 they pound chest really hard

I use RCF L18P for my subs, they are 18", the EAW KF850 uses 15'" and the frequencies call for a MID/LOW driver, the Eminence sounds really good on those cabs.

I have done the same, and they sound just as good as the RCF.

Eaw has originally used three types of 2 "controllers: JBL, TAD and B & C. I have the JBL motors, they sound very sweet and are less strident than the TADs, although in either case, the replacement of the round membrane The B & C engines are the most common in the 850 European boxes, the parts are cheap and the price is very low. Although it is inferior to TAD or JBL in quality, they do not give bad result. The American boxes almost all have installed motor TAD.

Que modelo exactamente jbl usa quiero cambiar los b&c son muy agradecivos
