    Default Would I damage my speakers if...

    Would I damage my speakers if..... I were horizontal bi-amping and accidentally ran a lot more current into the bass than into the treble (or vice-versa) ?
    Speakers are DALI Opticon 6 (using internal crossover) - Intended Amps: Arcam Integrated A39 x 2 (120W per channel at 8 Ohms)

    Thanks, Roland

    Yes if you run too much power to the tweeters. The bass unit will probably handle it provided you don't run full power through it for any length of time.

    .. in which case I would hear that there's way to much power to the tweeters, right ?

    Maybe not. They could blow very quickly

    I doubt you'd get any warning.

However, you would (should?) notice that the sound is overly bright and would (should?) do something corrective before its too late. But surely, if you're running all four channels of amplification from one pre-amp, it would be impossible to turn up the tweeters without turning up the bass drivers.

    Why do you ask?
    Horizontal = One integrated amp for bass and one for treble...
    Each amp has a volume control of its own
    I think I would hear something horribly wrong way before I blew the tweeters... but good that I am warned beforehand of potential blunders
    You're asking why 2x A39 integrated amps ? because they're on offer at 60% RRP and the dedicated "matching" power amp costs 4x the price of a discounted A39

    No you won't. They tend to blow instantly, without warning.

    If the 2 Amps could be run off a pre then it would be safer. Or go vertical biamping

    I have a friend who is running a pair of JBL K2 S9800 speakers with Benchmark amplifiers, and these are horizontally bi-amped. He has split the pre out into each of the power amps, using only the one pre volume control.

    It should be possible to guesstimate fairly accurately the relative levels of top and bass by ear, but dependant upon the Xover point, the energy to the tweeters will be considerably lower than to the woofers, and IMO you are unlikely to blow them unless playing silly and/or clipping levels.

    If you use a passive pre, setting both amps at the same dial volume, starting at say half volume, this should mitigate any issues I would have thought. Removing the chance of inadvertently increasing the volume on one amp. The passive pre is now master volume.

    You now have variable gain power amps, which can have useful benefits?
