I'd like build a Cornscala with APT150 supertweeter and Atlas PD5 VH mid driver on the Altec 511b midhorn for my home built SE 2a3 monoblocks (I don't like loud music..., enough about 100 dB/1W speaker ). The problem is the woofer. I find this speaker: Eminence Kappa-15LFA. 8 ohm. Parameters: Le: 1.27 mH *Impedance: 8 ohms *Re: 5.4 ohms *Frequency range: 38-2,700 Hz *Magnet weight: 95 oz. *Fs: 39 Hz *SPL: 99 dB 1W/1m *Vas: 5.6 cu. ft. *Qms: 6.08 *Qes: 0.41 *Qts: 0.38 *Xmax: 5.5 mm
The question: can I use this woofer and which modifications necessary in the x-over? (i know the original x-over made for 4 ohm speakers.)
Unfortunately, the original or Crites's woofer shipping cost is very expensive from USA , however, this woofer can be obtained cheaply in Europe.
Plese help me!
