Title: Eminence KAPPA PRO-10A in WO Post by morpheous85 on 09/18/06 at 08:40:45 Would it work? It doesn't seem terribly far from the DHM-108b DHM-108b RMS 275 Watts Peak Power 400 Watts Sensitivity 1w/1m 90.5 dB FS (Hz) 40.8 Hz QMS 7.49 QTS 0.618 VAS (cubic ft) 1.87 (53 liters) XMAX (inches) 0.39 Eminence Power Rating 500W Music Program 1000W Sensitivity 1w/1m 97 db Resonance 46Hz Mechanical Q (Qms) 10.10 Total Q (Qts) 0.20 Compliance Equivalent Volume (Vas) 52.2 liters / 1.8 cu. ft. Maximum Linear Excursion (Xmax) 0.12in Maximum Mechanical Limit (Xlim) 0.43in The Qms is higher and the Qts is lower on the Eminence. However, I can't get over the 97db and 1000w. That's 127db, not counting the WO gains. |

Title: Re: Eminence KAPPA PRO-10A in WO Post by Braggi on 09/21/06 at 20:07:25 Eminence is pretty well respected in the industry. Can't imagine they'd need to fudge specs. OTOH, I agree there are a lot of good reports on this forum for many different drivers. |

Correct me if I'm wrong, but the XMAX for the eminence is woefully lacking! roughly 1/3 of the dhm-108b |
Title: Re: Eminence KAPPA PRO-10A in WO Post by aznboi3644 on 09/21/06 at 23:11:39 Must sacrifice Xmax for sensitivity...can't have both |
Title: Re: Eminence KAPPA PRO-10A in WO Post by Braggi on 09/22/06 at 18:38:04 Here's a good question: Is an Xmax of .12 (nearly 1/8") enough for use in a WO using a pro sound woofer? The Eminence woofer in question has a Xlim of .43". I suppose once you've exceeded the Xmax you're dramatically increasing distortion, but I don't think it would damage the driver. Somebody straighten me out if I totally don't understand. |
Title: Re: Eminence KAPPA PRO-10A in WO Post by Adrian D. on 09/22/06 at 19:17:45 iirc, prosound drivers have xsus and xmag considerably bigger compared to xmax. it's there just in case something happens to make sure the speaker survives. drivers with high xmax have an xsus and xmag closer to xmax. i'm not sure if most manufacturers measure xmax where the motor force dropped to 70%. but if that's the case, distorsion increases a lot when you exceed xmax. also, the woofer will "tell you" if it doesn't like the amount of power. only problem i see with the kappa is it's ability to go low. sealed box means you need some xmax to be able to reproduce the lows. but the wo will work magic. if you are going to use it for pa, lows aren't such a worry. |
