| Letters -- April 2008 "I haven’t considered it, therefore I won’t consider it." April 29, 2008 Editor, In your article titled “Challenging Long-Held Beliefs” you state that some audiophiles state things like, "I haven’t considered it, therefore I won’t consider it." That is truer than perhaps you even realize. I find that it applies to anything new in numerous consumer markets. Once a noted expert puts his or her stamp of approval on it, however, things can change quickly. I will look forward to seeing what you feel are worthy products that most audiophiles would not consider. The Anthem D2 article will surely be a proper place to start. Jonathan Vargas I know in my audiophile life change has often been avoided, but once I’ve decided to dive in, I open myself up to other ideas rather quickly. That’s where I am at personally now, and you’ll have an opportunity to read about what that has meant to the fidelity of my system in detail in the near future. Look for the Anthem article in June….Jeff Fritz Gotham questions April 17, 2008 Editor, I greatly enjoyed your extremely thorough review of the JL Audio Gotham g213 subwoofer. You went beyond what I have seen anyone else do in order to integrate a subwoofer properly into your system. For a system like yours, I think you did what was necessary in order to add to your system, not degrade it. I do have one question: Is there a way to use speaker-level inputs on the Gotham, as with the Rel subwoofers? If not, do you think this would enhance their usefulness? Ben Zanko I have heard the arguments for using speaker-level inputs on subwoofers in order to get the same signal going to the sub that goes to your main speakers. Honestly, I’m not convinced, and here’s why: The main issues involved in integrating a subwoofer into a high-end system are acoustic in nature. These issues are addressed through room placement, phase and crossover adjustment, level matching, and room correction. These issues will swamp any amplifier signature that comes through the speaker-level inputs to a subwoofer. And using the speaker-level inputs really do nothing to address the aforementioned issues. While I’m sure there will be folks who disagree with my assessment, consider this: if you wired your speakers out of phase and skewed their placement in your room by several feet, how much sonic price would you pay? You’d ruin your sound of course. Same goes with a subwoofer. So my advice is to get the real issues solved and not worry about the lack of speaker-level inputs. Phase explained April 4, 2008 Editor, I can’t fathom (Gotham?) why you would need as much bass as two JL Audio Gotham subwoofers could produce, but I do enjoy reading about such extreme adventures. I am also keen on employing your tips on phase in my own system, which uses one (soon to be two) JL Audio Fathom f112 subwoofers. I have not seen a better explanation of phase integration anywhere. Kudos to you and Ultra Audio for going the extra mile in explaining it. Reggie D.
