|   Speaker db sensitivity rating? | Ace H
Nov 28, 2001 5:52 PM | | Does a higher speaker dB sensitivity rating mean that you have to turn up the volume to get a "normal" listening level? |

Nov 28, 2001 8:11 PM | | I'm confused here....you state "It is a figure on how easily amped the speaker is and NOT how loud you can get the speaker to play."
Can't "amplification" and loudness, in this regard, be considered synonymous? Therefore a speaker with an 88db sensitivity rating will have a LOWER volume than a 90db sensitivity speaker at the SAME loudness level? |

Nov 29, 2001 12:19 PM | | Sometimes it is so, but if your amp is not the limitation in your system some of the speaker with lower db rating can give out a much higer sound in db if you can supply them with enough power.. If you have a smal amp you get more (higher in db) with a high db-rating. Remember that a high db rating isn't equal with good sound. A car alarm siren often produces sound in the area from 90-120 db. |

Nov 28, 2001 9:24 PM | | Efficiency is what SPL it will produce with 1W of power.
Sensitivity is what SPL it will produce with 2.83V across the terminals.
For an 8ohm load Efficiency = Sensitivity.
Just remember, its all about tradeoffs. Speaker designers want a high efficiency, but in order to achieve say good bass response, they have had to trade efficiency in order to achieve it.

Nov 29, 2001 5:15 AM | | Ok...now I'm starting to get it. Efficiency is the key word here. That's what I was looking for.
Regarding the statement about trading efficiency for a good bass response, I was looking for speakers that are efficient with a decent bass response. That's why I was aksing about the db sensitivity rating. |

Nov 29, 2001 3:05 PM | | A speakers effiency or sensitivity rating is NOT directly reflectant of wether or how it produces bass. It is a rating that will tell you how "easy" the speaker is to drive...Also...how "easy" the speaker is to drive can depend on other factors...such as the imedance curve. But, sensitivity and efficiency will tell you nothing about the sound, or quality, of the speaker!!!!
enjoy the music! |

Nov 30, 2001 10:37 PM | | are the Talon Khorus...Will reproduce frequencies down to 17Hz...and operate with wattage from 1-1000 watts. I've heard them with a 2A3 amp (3.5Wpc) and I can tell you it did not lack in anything. Of course the woofer they chose is an efficient one. System matching is the key! When building your system do the same...pay attention to system matching(or synergy)

Nov 29, 2001 7:54 PM | | Should have made myself more clear...
Its called Hoffmans Iron law.
You have box size, efficiency, and bass extension.
You can choose 2, and your stuck with the 3rd. Think of it as a pie, you can cut 2 slices as large as you want, but the third has a fixed size...
For instance, pro audio speakers have little bass (they add a seperate sub), but they are hyper efficient, often over 100dB/W. |
