25 TO 30 YEARS AGO EV PRODUCED A WORLD BEATING REVOLUTION IN SMALL, PORTABLE BUT HIGH POWER PA/MUSIC SPEAKERS. (CAN’T FIND ANY EXACT DATE FOR 1^ST. & LAST YEAR OF MANUFACTURE THESE – IF ANY ONE OUT THERE KNOWS WOULD APPRECIATE THE INFO) THE INCREDIBLE SMOOTH PEAK FREE RESPONSE OF THE S200 GIVES 3-6DB MORE ACOUSTIC OUTPUT BEFORE FEEDBACK THAN ANY OTHER SPEAKERS I HAVE USED OVER MANY YEARS AND BEAR IN MIND 3dB IS THE SAME AS  DOUBLING THE AMP POWER OF A SYSTEM (IE. 300-600, 600-1200 ETC.) A COMPETENT USER WITH A BASIC KNOWLEDGE OF PA SETUP CAN PRODUCE UPTO TWICE THE VOLUME WITHOUT FEEDBACK OF MANY OTHER SPEAKERS AND PRODUCE A CLEAN UP TO 125dB of  SOUND PRESSURE LEVEL.

THE EV S200 IS ALWAYS SUPERIOR TO MOST OTHER SPEAKERS IN THE £600-800 (ACCORDING TO MANY BETTER THAN THE SX200-300) AND IN MOST CASES AT LEAST AS GOOD AS STUFF IN THE £1000-2000 (MARTIN, TANNOY, FBT ETC) RANGE! SO A GOOD REFURBISHED PAIR OF S200’S AT £300-400 ARE IN MY OPINION THE BEST BUY AND FOR THE FUTURE  RECONES AND TWEETER DIAPHRAGMS ARE READILY AVAILABLE. FOR THE SERIOUS USER EV S200's ARE FOR LIFE!

AGE RELATED PROBLEMS DUE TO THEIR AGE THESE THE S200 CAN HAVE MANY PROBLEMS SUCH AS COMPONENTS ALMOST DROPPING OFF THE CROSSOVER, WE REWORK ALL XOVERS AND ARE NOW FITTING A NEW POLY SWITCH (*SEE NOTE ON TWEETER PROTECTION POLY SWITCH). SPEAKER CONE LOWER SUPPORT IS OFTEN DETACHING, CONE EDGE DETACHING FROM THE FRAME, TWEETER CONNECTIONS LOOSE, ALMOST DROPPING OFF  AND WE HAVE ALSO FOUND SO MUCH FLUFF AND DEBRI BEHIND THE TWEETER GRILL IT WAS A WONDER ANY HIGH FREQUENCY WAS GETTING OUT AT ALL.  THESE PROBLEMS CAUSING INTERMITANT FAILURE IS WHY MOST PEOPLE SELL THEM. BEFORE WE PUT A S200 ON SALE THEY ARE STRIPPED, REFURBISHED - PROFESSIONALY CLEANED GRILL CLOTH AND REFINISHED TO BEST POSSIBLE STANDARD BEARING IN MIND THE AGE. THE OLD JACK SOCKETS ARE RETAINED BUT NEW SPEAKON SOCKETS ARE ADDED FOR RELIABLE CONNECTION.

*NOTE ON POLYSWITCH THE HF/ TWEETER PROTECTION CIRCUIT USES WHAT IS KNOWN AS A POLY SWITCH WHICH COULD BE DESCRIBED AS A TEMPERATURE DEPENDANT RESISTOR. IT IS A ‘RE- SETTABLE FUSE - WHEN RUNNING AT NORMAL TEMPERATURE IT IS CLOSED (SWITCHED ON) AND THE POWER TO THE TWEETER PASSES THRU IT. WHEN THE CAB IS OVER DRIVEN IT HEATS UP AND SWITCHES OFF (OPEN) AND THE POWER TO THE TWEETER PASSES THRU A 10 OHM BALLAST RESISTOR THAT CAUSES A 6db DROP IN POWER TO THE TWEETER. WHEN THE POWER IS REDUCED IT COOLS DOWN AND CLOSES AGAIN RESTORING FULL POWER TO THE TWEETER. INVESTIGATION SHOWS THAT AFTER MANY YEARS OF RESPONDING TO OVERLOAD CONDITIONS THE INTERNAL RESITANCE OF THE POLYSWITCH INCREASES THIS CAUSES THE POWER TO THE TWEETER TO BE CONDUCTED THRU THE 10 OHM BALLAST RESISTOR CAUSING IT TO OVER HEAT AND EVENTUALLY BURN OUT. THIS INCREASED RESISTANCE IN THE POLYSWITCH IS OFTEN THE CAUSE OF THETHE SOUND LEVEL OF ONE HORN BEING LOWER THAN THE OTHER. THERE IS A PHOTO ATTCHED TO THIS LISTING SHOWING THE CROSSOVER BOARD BURNT RIGHT THRU. 

WE NOW FIT A NEW XOVER POLYSWITCH TO ALL CABINETS WE REFURBISH.

ORIGINAL COMPONENT INFORMATION.

12” BASS/LOW MID DRIVER. PROLINE EVM 12S PART NO 812-82901 OR SIMPLY THE ‘12S’.  THIS 12” SPEAKER HAS BEEN  THE MAINSTAY OF THE EV 12” SPEAKER RANGE FOR APPROX 30 YEARS RIGHT UP TO THE SX 200 RANGE. IT’S SIBLING THE ‘12L’ WITH A SLIGHTLY DEEPER CONE IS USED BY SANTANA, FORMERLY GARY MOORE (RIP) AND MANY MORE WORLD FAMOUS MUSICIANS. THE 12L IS ALSO USED IN MESA BOOGIE AMPS AND MANY OTHER FAMOUS CUSTOM BUILT AMPS.

 ‘SUPER DOME’ TWEETER HF UNIT PART NO 8127 THE S200’S FAMOUS HF DRIVER IS UNIQUE  AND PROVIDES A SMOOTH SWEET CLEAR SOUND UNEQUALED BY MODERN DAY COMPRESSION DRIVERS AND IS ONE OF THE REASONS THE S200 IS FAVOURED OVER THE LATER SX RANGE REPLACEMENT.

PASSIVE INTERNALCROSSOVER PART NO 8209 THE S200’S CROSSOVER IS EXCEPTIONAL AND CONTRIBUTES GREATLY TO THE SMOOTH PERFORMANCE OF THE UNIT – AIR CORED COIL INDUCTORS AND HIGH QUALITY COMPONENTS MAKE THIS A CROSSOVER ENVIED BY MANY - TOTALLY SUPERIOR TO CHEAPER PEAKY UNITS WITH FERRITE CORED INDUCTORS.

NOTE ON POWER HANDLING.To obtain the best results and full capacity skilled experts in sound will obtain the best results with a power amp 3-4 time that of the speaker continuous rating. BUT READ AND UNDERSTAND THIS CAUTION This arrangement is only for experts or those who can discipline themselves against pushing the system for ever higher sound levels. A more conservative power rating is 0.7 (or 1)to 1.4 the speaker rating. To be very conservative 0,5 -0.7. THE S200 WILL GIVE ITS MAXIMUM SOUND PRESSURE LEVEL AT 300 WATTS CONTINUOUS PROGAM INPUT POWER TO GET THE BEST PERFORMANCE THE BASS RESPONSE MUST BE ROLLED OFF AT 60HZ. AS A RULE OF THUMB A 400 WATT AMPLIFIER WILL GIVE THE BEST RESULTS AND HANDLE THE PROGRAM PEAKS ADEQUATELY – BUT PUSHING MORE THAN 300 WATTS  CONTINUOUS  WILL NOT GIVE MORE VOLUME  JUST EVENTUALLY DESTROY THE SPEAKER. THE BEST PERFORMANCE WILL BE ACHIEVED USING A SUB WOOFER CROSSING OVER AT 180 -250HZ AS ANYONE EXPERIENCED WILL ALREADY KNOW.
