    Another panel aging question...

    May last 20 years and greater with the mylar not becoming floppy and mylar coating remaining 100% intact. For optimal performance keep them free of dust build up. I know no one is going to believe me except experts who designed the original CLS. My CLS age is 34.5 years. The panels at one point...

    CLX Art and very small rooms.

    On the REL website and from the point of view of subwoofer performance, a medium size room ranges from 200 to 400 feet square. Your room is 16 by 17 feet. 272 feet square. My room is 14 by 21 feet. 294 feet square. If your room was below 100 feet square in size may be categorized as very small...

    Tubes or Solid State

    Whether valve or solid state amplification what is best suited depends on the specific speaker. Not correct in this case to make a blanket generalization. For instance, the original CLS sounds amazing with the middle of the line up Audio Research tube pre and power combination. However, CLS 2...

    Motion 35xti amplifier suggestions

    https://www.musicalfidelity.com/products/a1/a1-2 This amp operates using best sounding circuit topology. Because of low wattage priced somewhat reasonably. Just my subjective opinion, speakers do not need high power. This amp has greater than enough power to drive 35XTi. I do not know whether...

    Hi, from Ian.... (newbie) Motion 35XTI question, replay levels.

    I may be mistaken because not 100% this is the reason. I experienced a similar problem approx. 12 years ago. When I tried to drive my full range CLS with a relatively lightweight Denon amplifier utilizing the stock inexpensive amplifier cable. Faced with a similar sonic phenomenon when increase...

    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...
