    Ascent power supply board failed - replace or repair/tweak?

    Hi Guys, There will be a difference in sound if the bias voltage is higher or lower then the other speaker. There's a couple of resistors on the board that can make changes to the voltage

    reQuest Crossover capacitor upgrade

    From my own experiment I can confirm that you can turn old ML speakers to be much better than stock. Yes when I opened up my Odyssey it was a real let down when considering the price I paid when new. Anyway what you said about the woofer caps is true, upgrading caps here to say film caps is a no...

    PanEl Dying, fix or move on

    No need to re-coat panels gents. There's a very nice gentleman in this forum who informed me that Ascent/Odyssey/Prodigy was produced using new vapour deposit coating which will not degrade over time & this coating is what is being used till today perhaps in improved form. The major issue with...

    More Volts = More / better sound?

    Question, with increase in spl, aren’t you creating an imbalance between panels & woofer ?

Well I don't know about you guys, I've been through 3 sets of ML speakers including a Vantage but sold all accept my Odyssey.

    Odyssey Bias Board Schematic

    Hi Roberto, I've already done what you've suggested. Originally board was working change 4 zener which was out of spec. When I re install the board it did not work, I only hear a distorted sound at high volume. Tried to measure dcv at C12 but unable too as the voltage kept fluctuating. Dilemma...

    Odyssey Bias Board Schematic

    Hi Again, Appreciate if you guys can provide a link to where I can find the bias board schematics, would be much appreciated if you could provide guidance on how I can go about trouble shooting the board. I did find some threads on trouble shooting but the bias boards are for Aries so am not...

    Odyssey Bias Board issues

    Sorry Jon, If I understand correctly these string of zener is kind of stablizing the voltage before the voltage multiplier. If this is so why are the last 4 zener tested opened with dvm ? Thank you again

    Odyssey Bias Board issues

    Hi JonFo, When I measured that string of diodes notice that the last 4 was opened so I thought zener are gone. Replaced with new zener , well it was still open when tested with dvm so am scratching my head on this. Thought problem was resolved as 1 panel is lower in volume. Good news though...

    Modifying the Odyssey crossover - my adventure

    Hi Guys, Having been inspired by your mods, I too did some tweaking on the Xover overall yes much improved over stock. less sibilance more clearer into the window of sound. I've also bypass the caps with 0.01 TRT caps which brought further improvement. Overall it sounds even more cohesive. Have...

    odyssey crossover resistor question

    Hi Guys Need some advice. Thinking of upgrading the resistors to Duelund but wattage available are 5 or 10 watts. If I remember correctly the resistors in the Odyssey crossovers are 30 watt rating so would it do any harm if I use either 5 or 10 watts Duelund resistors as repacment many thanks

    question about soundstage

    Your right Peter not toeing in does improve the sound stage but you loose resolution as the logans isn't a wide angle speaker. If we move the speakers closer they sound too congested . In my case the sweet spot seems to be around 7.5 to 8ft apart Thanks again
