INFINITY 150 WATT OVERTURE 1 SUBWOOFER AMPLIFIER S 220V

PLEASE READ THIS ENTIRE LISTING INCLUDING THE NOTE NEAR THE BOTTOM BETWEEN THE !!!!!!!!!!!!!!!!! BEFORE MAKING YOUR BIDS. I WILL NOT BE HELD RESPONSIBLE IF YOU NEGLECT TO DO SO

THIS IS THE 150 WATT AMP ASSEMBLY DESIGNED FOR THE SUPER COMPACT INFINITY OVERTURE 1 SPEAKER SYSTEM AS PICTURED BELOW.

 the pictures below are only to show how it was intended to be used.  these are not used/pulled units and i have no cabinets for sale

* * * *

SINCE THE CABINET WAS SO SMALL THERE IS EQUALIZATION BUILT INTO THE AMP TO COMPENSATE FOR THE ROLL OFF OF THE TINY CABINET. THERE IS ALSO "SUBSONIC" FILTERING BUILT INTO THE EQUALIZATION TO AVOID OVER-EXCURSION OF THE WOOFER.

THIS WOULD MAKE A GREAT AMP FOR A SUPER COMPACT SUB PROVIDING EXTENDED LOW FREQUENCY RESPONSE IN A COMPACT ENCLOSURE.

SINCE THESE ONLY ACCEPT A SINGLE CHANNEL HIGH LEVEL INPUT THE BEST USES ARE:

1) 1 PER SIDE FOR A SUB PAIR
2)  ACTIVE SUB SECTION IN CUSTOM TOWER SPEAKERS
3) A SUB PEDESTAL/STAND FOR YOUR SPEAKERS

HECK, MAKE 5 OR 7 SUBS IF YOU HAVE 5.1 OR 7.1 AND HAVE A SUB ON EVERY CHANNEL ;-) (WE HAVE A FEW HUNDRED AVAILABLE ACTUALLY)

HOW TO ADJUST YOU RECEIVER TO USE THESE WITH A 5.1 OR GREATER SYSTEM
(YOU MUST USE A PAIR MINIMUM):

1) CHANGE THE SETTING ON THE "MAINS" TO "LARGE" OR "FULL"
2) IN THE "LFE" SETTING, SET TO "MAINS"
3) LEAVE ALL OTHER SPEAKER SETTING AT "SMALL" OR "NORMAL"
4) ADD A CAPACITOR TO THE LINE FEEDING THE MAINS TO BLOCK THE BASS FROM GETTING TO THEM, WE HAVE THESE FOR $2 EACH 

SET THIS WAY THE SUBS WILL STILL GET ALL THE BASS ENERGY THAT THEY WOULD IF CONNECTED TO THE SUB OUT RCA AND YOU STILL HAVE "LFE" LEVEL CONTROL CAPABILITY

BELOW ARE PICTURES OF THE DATA SHEET THAT COMES WITH MOST OF THE UNITS. ALL ARE VERY SIMILAR SO THIS SHOULD GIVE A GENERAL IDEA. THEY WERE VERY LIGHT PRINT SO I HAD TO CRANK THE CONTRAST TO MAKE IT READABLE, SORRY FOR THE ODD COLORING

IN THE PICTURE BELOW YOU CAN SEE THE LEVEL OF BOOST OR CUT AT THE VARIOUS FREQUENCIES REFERENCED. MAXIMUM BOOST CAN BE SEEN AT 30 HZ WITH AROUND 11DB AND ROLLING OFF ABOVE AND BELOW

THIS ONE SHOWS THE THD FIGURES AT VARIOUS FREQ'S. THESE ARE EXTREMELY LOW DISTORTION FIGURES FOR A SWITCHING AMP

MORE INFO

I HAVE PRICED THESE LOW AS I HAVE HAD A FEW WITH PROBLEMS IN THE PAST BUT I LATER FOUND I WAS RUNNING WOOFERS WITH TOO LOW OF AN IMPEDANCE. I BURNED 3 OF THEM MYSELF BUT ALL I HAD AVAILABLE AT THAT MOMENT WAS 4 OHM WOOFERS. I THEN RAN IT ON AN "8 OHM" WOOFER (ONE OF THE GOLD JBL'S WHICH I HAVE NOW FOUND OUT ARE 6 OHM WOOFERS) AND BURNED ANOTHER.   I HAVE SINCE RUN THEM ON 8 OHM WOOFERS WITH HIGHER DCR AND HAD NO PROBLEM. THOSE 4 ARE ALL I HAVE BLOWN AND  WERE ALL ON 6 OHM OR LOWER WOOFERS.  I HAVE USED MANY MORE FOR MISC APPLICATIONS WITH NO PROBLEM BUT I JUST MADE SURE THE WOOFERS HAD A GOOD X-MAX AND ARE MINIMUM 8 OHM WOOFERS

DO NOT USE THIS AMP BELOW 8 OHMS, 16 OHMS AND UP PREFERRED!!!

SINCE I HAVE STARTED LISTING THIS ITEM I HAVE RECEIVED INFO FROM 2 PEOPLE, 1 STATING IT IS FOR A 16 OHM WOOFER AND ANOTHER CLAIMING TO BE A REPAIR TECH FOR INFINITY STATING THEY ARE FOR 30 OHMS...  AGAIN I HAVE USED THEM AT 8 OHMS AND NOT HAD A PROBLEM BUT I GUESS TO BE SAFE THEY SHOULD BE USED AT LEAST AT 16 OHMS (DUAL 8 OHM WOOFERS, A DUAL 8 OHM COIL WOOFER ETC IN SERIES...)  I ACTUALLY TRIED IT AT 36 OHMS RUNNING A PAIR OF MY DUAL 8 OHM SHEILDED SUBS (PICTURE BELOW) AND IT WORKED QUITE WELL SO THIS WOULD BE BY FAR THE SAFEST BET
