big_gto Posted April 24, 2003 Share Posted April 24, 2003 Does anyone have an a ideal how many 10" woofers I would need to compete with a 15" woofer. My Klipsch kg 4.2s don't have the bass my deceased Pioneer HPM-1100s used to create. More importantly, which Klipsch speaker would compare?

lynnm Posted April 24, 2003 Share Posted April 24, 2003 If by the word compete you mean How many 10" woofers are required to equal the total cone area of a 15 the answer would be 3 based on the area of a circle being calculated as per the standard formula which is: pi rsquared In other words: Calculation for Cone area of a 15" woofer < 3.1412 X 56.25 = 176.6925 > Calculation for Cone area of a 10" woofer < 3.1412 X 25 = 78.53 > Therefore 3 10" would provide a larger surface area than a single 15" That said - Surface area of the cone is only one factor among many needing to be taken into account when determining potential acoustic output at any given frequency. Among them: Stiffness of the cone Stiffness of the suspension Type of enclosure Size and shape of the room Acoustic character of the listening room "Type" of Bass response expected/desired by the user. A speaker can be designed to give what seems to be tremendous bass response by the simple expedient of introducing a resonant peak into the design at about 60 hz. That speaker will sound more potent in the bass range than a more accurate speaker and for some users that will be seen as desirable.
