    Classic 9 amp consideration: Sanders vs Anthem

    A very useful concept or idea put forward by Leporello. I will explain with an example. Anthem MCA 225, if you read the manual, max power output single channel driven is 550 watts @ 2 ohms. If we consider both channels driven simultaneously this measure is lower, namely, 370 watts @ 2 ohms...

    UNABLE TO UPGRADE STR INTEGRATED AMPLIFIER FIRMWARE OR SOFTWARE.

    In hindsight there is a need to link the target device to the PC rather than directly to the modem. Command is required that originates from the ARC software running on the PC and results in target device firmware being upgraded to the latest version. Upgrade of firmware takes place via...

    Making Vantage Sealed Box (Port Plug) Question

    I used to have a KEF Q series bookshelf that came with a factory supplied foam to block the port. Based solely on this example if Vantage delivered with factory supplied material to block the port, then I imagine no harm to woofer may take place. And if allowed specifically in manual.

    Bass Advice

    How will subwoofer null frequencies outside its upper limit produced by Summit? Typical subwoofers cover the lowest frequency range. Subwoofer positron waves or out of phase waves with main speaker waves would reduce by nulling or annihilating only subwoofer range sound frequencies. Subwoofers...

    Bass Advice

    Prior to experimentation with absorptive and diffusive material get the placement right. Placement helps to remove or minimize boomy bass. And at the same time allow maximum or optimal performance of the panel. Inside ML Classic ELS 9 instruction manual a formula for inside room speaker optimal...

    Another Amp / Impedance / Bi-amp question

    My understanding biamping works best when both amplifiers are identical or at least have similar gain. If one amp does not provide enough amperes to optimal drive loudspeakers, then another identical map is required. Therefore, used together they adequately drive or if they match the loudspeaker...

    Hey there from Washington DC

    I first thought perhaps the fault is in ELS 9 panels. However chances are the power supply circuits are defective. Thanks to Martin Logan honouring the warranty I got both replaced. Following is the reason why I say the above. I used to bi-amp ELS9 with 2 similar anthem power amps each max. 370...

    Reviving older ESLs - burn-in required?

    Crossover is designed keeping characteristics of electrostatic or electromagnetic drivers in mind. If the German electrostatic driver is not an exact copy of the original.

    Reviving older ESLs - burn-in required?

    If the former owner took good care of the panels when placed in storage. Perhaps when in operation not expose them to sunlight, smoke, limited dusty environment, cover them when not in use, kept in a cool environment and regularly vacuum. If panels are not exposed to corrosive environment such...

    Reviving older ESLs - burn-in required?

    If the speakers truly come to life at higher volume then they should not sound bass heavy. Sound bass heavy one reason is the panel output is weak. Despite being bass heavy and listening carefully at the volume just when the panel comes to life. If you think panel sonics are greater compared to...
