Usually musical instrument speakers are high SPL (96 dB and up), but those are mainly for voice and midrange. High SPL studio monitors get real loud because they have a light cone and a large magnet and other characteristics that make them loud. Since this is a sub; it will have to create volume by having a heavy cone and an even larger magnet, voice coil, etc... Anyways, I ran the thiel small parameters on it through BassBoxPro 6, and it looks really impressive. It goes down to 5 Hz in a .724 cubic foot box sealed and stuffed. Remember this is a 6 ohm driver, so you will need to find an amp that will put out 400 watts at 6 ohms (not 4 ohms). |

USA Post Number: 704 Registered: Apr-05 | Wait, For some reason when I inputed the thiel large parameters from the Eminence acrobat reader PDF file, the thiel large parameters are differenmt from the thiel small parameters posted on the parts express website. So, here are the new more realistic box alignments. Vb = 1.317 cubic foot sealed (no stuffing) QTC = .707 QL = 6.946 F3 = 46.58 Hz VB = 3.073 cubic foot ported box FB = 22.13 Hz QL = 6.946 F3 = 26.45 Hz Dv = 3" LV = 10.7" This is more like it. |

The Eminence has a higher Bl, Higher Qms, Lower Qes, and a bigger magnet. The only things that the dayton has over the Eminence is the Vas is lower, and has a higher Qts (better for smaller sealed applications). The Eminence rocks at 15 Tesla Meters (Bl). This thing is going to pound. OUCH ! |
