Question about Infinity SM 255 Speaker

1 Answer

Repair or replace?

I have a set of Infinity SM-255's. Recently one of the subs stopped working and after inspection found there to be a rip/split at the bottom of the sub. Is this what a "blown" sub is??? Do I need to repair or replace it?
I currently run a Yamaha RX-540 rec through the Infinity's.

If the sub requires replacement, could anyone advise me on what brand to replace it with, due to Infinity not producing the SM line anymore.

Regards,

Kiwi Boy NZ

If the rip or split extends from the voice coil out to the edge, the speaker may be too far gone to replace. I have repaired expensive speaker cones with epoxy cement, provided the tear is fairly small or narrow. No noticeable degradation of performance either.

Go on eBay and search for "infinity speaker foam repair" and add the diameter or just thumb through what comes up.

PS-212 Suddenly stopped working


I HAVE 4 PS212 AND FROM WHAT YOU ARE DISCRIBING SOUNDS SIMILIAR TO WHAT HAPPENED TO ME. PLAYING THE SUB AT FULL VOLUME AND CLIPPING OCCURED NOT KNOWING THAT THE FAINT SMELL WAS THE VOICE COIL BURNING AND CONTINUING TO PLAY UNTIL KNOW SOUND LESSON LEARNED BUY A BIGGER SUB SYSTEM OR REPLACE YOUR SUB WOOFER.
IN MY OPPINION THIS IS A VERY GOOD PRODUCT WHICH I HAVE BEEN ABUSEING FOR MONTHS . SO QUIT WHINEING AND PAY YOUR DUES.

1 subwoofer stopped working in a box for 2


Hello mccanello55,

You need to remove the subs from the box in order to check the internal box wiring. First, make sure that the wire going from the nonworking sub terminals to the enclosure terminals is OK. Then check the "braided" leads on the back of the terminals going to the speaker cone. If the wiring all looks OK, remove the wires from the sub terminals, and use a multimeter set to the lowest ohm range and check the resistance across the subs terminals. You should read somewhere between 3-4 ohms. If the meter reads infinity (that is no reading at all), then the voice coil is open. If it "pegs" (reads "0"), the coil is shorted.

Either open or shorted means the voice coil is no longer working.

I could not find any replacement parts on Sony's support page, so it's most likely that they don't even repair these. They probably just replace the sub if it's under warranty, and if it's not under warranty, they probably recommend that you buy a new one.

Hope this helps.

2 sets of pos. and negs. on 10" infinity reference 1052w


This means you have a dual voice coil sub. It is probably a dual 4 ohm voice coil. If you hook up the left channel to one input and the right to the other you can safely push the sub but the amp will be running at a lower efficency. In other words it isn't the best amp for the job because it can't push max power to a dual voice coil speaker but it will work.

Protect light flashing/ticking


this problem sound like you have too low of power going to your amp, test your battery and make sure its putting out enough power for at least the mininum amount of power that your amp requires, you can find that information in your manual or sometimes they post it on the amp itself. i hope this info helps
