Why does any manufacturer not include meaningful specs with their products? It's impossible to evaluate a speaker without real numbers unless you can actually demo one in a real-world environment. |

If Systune and Smaart files were available for download, one would be able to compare between manufacturers in much more meaningful ways. Grant |

Ivan, what would make sense to me (and most semi-tech guys) would be the basics, some of which are already common: Operating range, +/- 3db Graph showing response in full or half-space, actual measurements of 1 box, not modeled or calculated Rated power handling, basic stuff, no "dog watts" or other BS Physical dims and weight Max output as actually measured, not calculated Things I would find useful that others might not would include measurements off-axis in a real-world environment. Some manufacturers do include some or all of this stuff, but marketing seems to creep in even then, such as the apparent practice of using the highest number measured as the 1w/1m spec, even if this number is outside the normal application. |

What is the distance from the subwoofer to the farthest row that you want to hit with 110db? |

The room is shallow and wide in a fan shape, so the farthest row is only about 40 feet from the stage, maybe 45 since I want to put the subs at the center of the stage. I had never heard of Grund Audio, but their flat mounted dual 18 may be perfect for my application and I see nothing but good reviews. What is the price point of the Fulcrum? I really need to keep it under $2000 each to get it financed. Honestly, the low cost of the Grund ($1400) almost makes me nervous. Does anyone else want to chime in on the Grund subs? |

Not sure how you'd specify bandwidth or crest or...? |

Yeah I see all that happening soon. |

[I'd like to see the specified useful frequency response range actually used for specified peak power testing, without driver damage or outrageous distortion from cone flap. . |

Ivan, that is my point. I can look at a graph and at least see the actual response IF the graph is accurate and legible. Even if it is the standard 1w/1m info it is useful if you have several other boxes with the same info. You are correct, +/- 3db is only useful if you know what it is referenced to. I'd rather have the graph. Silas, you are correct. It is not possible unless everyone uses the same standards, and that will never happen. |

Speaking from a manufacturer perspective, we have been asked to provide certain specific data. Yet no other manufacturer provides this data. So somehow the cutomer who requested it is going to use it to "evaluate" the product and then attempt to compare it to a product that does not have that data. How is that possible? |
