Dave's Homepage audio home The Vifa X3 Preamp Car Audio Shiva! PA Speakers Hafler stuff Phase Linear LM3886 amp lm12 amp

It uses the P.Audio BM-15LF in a 3.5cuft box tuned to 34Hz. Cross it over at 80Hz ish. Max output is near 120dB or so. Corrected F3 in the range of 35Hz. Data: Simulated frequency response of the -15LF in the box Simulatedpower handling of the -15LF in the bove mentioned box Driver data sheet This should work out nicely. If you take the data and set the HF cutoff at around 70Hz, the little bugger will put out somethig close to 120dB in anechoic halfspace. Figure 123dB in a real room with walls and a ceiling.F3 is ~35Hz in such a scenario. Comments? email me. Dave Paton        |        dave@dpaton.net        |
