  • IRS v woofer tower active feed back

    Over the last week one of my towers had a low rumble when playing or not
    I read through the service Manuel and made a phone call to mark a very nice guy and knows plenty about infinity speakers
    he felt as I did it could be a loose accelerometer in the woofer
    I took things apart and found nothing wrong
    the connections inside seemed fine and a small rf type shielded coupling is used to remove the woofer
    putting it back and turning it back on was a wow moment
    has anyone ever heard what 2K watts and 6 12 woofers can do you may be surprised given this is only one half of the woofers.
    In trouble shooting first part is to remove the servo sensor
    and play this was fine a bloated bass but fine wow does that servo make things good

    next a complete reboot
    well In playing loud passages I have vibrated various bid to parts as hair yes hair and fat even my eyes lol
    but what happened next was an amazing show of thunder in my room like I never have heard before I felt the air as I ran to shut it down.
    Anyway a simple loose connection of the servo was the cause no damage and playing fine now.
    I truly have a new raspect for these woofer towers now
    also for anyone who has a pair the woofers are labeled IRS v and the Amps have two huge toroidal transformers amd 8 large caps the IRS 1/2/3 one 4 caps and one transformer also white woofers.
    My resonaing for posting is be aware of our subs with Servos this can happen to other types as well and very not so good experience for those who leave there Amps up and powered all the time as I don't anymore lol.

      Yes pretty simple I have been looking into having the Amps serviced for a while. I was on the phone with the man who actually made the Amps hiw cool
      is that. No need to send them in he feels they are fine
      he also remarked on the caps to be left alone he feels old ones last longer than new ones. I opened both as instructed all is fine. I am planning on selling all my stuff and would never hurt anyone who. Buys them.
