    Considering that isn't an exterior wall, it's possible that the gear that powered those speakers was on the opposite side of that wall. It's also possible that there is money hidden in there somewhere. $$$$

    ....Or run up to the attic, and cut off maybe...

    The topic is "Thoughts on SDA's...."

    Something we agree on. This thread was about helping someone understand differences between SDA models. Until you hijacked it with the same old arguments trying to start something...again.


    The discussion was hijacked way back when a few started scolding several, including the O.P. for daring to call the SDA effect an "Effect"

    Or did you miss that?

    I see someone didn't read the explanation of what SDA is. Once again, it is not an effect. Non-SDA stereo speakers would be more accurately described as having an effect.

    Non-SDA speakers are used in virtually every recording mastering and mixing studio, therefore soundstage and stereo effects are optimized in house for normal non-SDA speakers.

    Your comments are based on sales literature and the "White paper" from Polk and are in conflict with real world experiences with recording, mixing and mastering personnel.

    The Polk white paper ignores certain facts about how actual recordings are made over the last 4-5 decades and instead concentrates on a theoretical recording style that has the listener sitting in the middle of a concert hall, and hearing the sound and scope of the hall itself.

    Since almost all recordings are completely created in studio, and the resultant sound stage and stereo effect are done with normal speakers, similar to what is used in home, the SDA effect may be quite enjoyable, fun and even sound better, but it will never be a more accurate representation of what the recording engineer intended.

  • Re: Long Speaker Cable Run

    yes i would try to get 10 gauge for over 20 foot. thicker wire can carry the signal farther easier

    Even 14 Gauge has very low resistance.

    True, they are not run full range, the difference being in the drastic changes a movie soundtrack has. Those surrounds can be quiet as a church mouse one second, and a cannon shot in the next. Those quick transient responses require reserve power to handle, or that cannon shot sounds like a cap gun. Music is the same way.

    Running in 2 channel mode, you'd probably not have to worry about anything with fairly efficient speakers, but speaking for myself....I wouldn't even consider putting it on a 4 ohm speaker, unless you listen at very low volumes, but then your listening without any real dynamic impact.

    Turning up the volume will put stress on the receiver, introduce distortion....as the specs show, and possibly do a smoke dance around a tweeter or 2. Point is to err on the side of having too much power than you need, not walk the line between too little and possibly doing damage. Make sense ?

    All of what you say, makes sense in theory, but we have actually tried Running 4 ohm speakers as I said, and while theory says not a great idea, it was nowhere near as bad as we imagined is all I am saying.

    FYI, it would play fairly loud and still sounded decent is all. It did get a bit warm for sure, but never distorted or shut down or made the music sound bad.

    What AVR's have you tried this "Torture" test on?
    Are you speaking from actual experience or what you have heard?
