Romy,

     What you say about both series and parallel filters is true. The parallel circuit does eat transient response, but if you keep the minumin impedance higher, it does not stress the amplifier so much. For your 16 ohm woofer I would try a 20 ohm resistor and a 27uF or 28uF capacitor in series and place it across the woofer terminals. This acts some what like a Zobel network, but will maintain a minumin inpedance of 11.3 ohms to the amplifer at 300Hz. As frequnency rises, of course impedance will drop, but at higher frequencies the amplifer should not be too challenged. It is possible it could screw with the mid range horns, but this would have to be listened to in order to determine how much damage it does. Other than this, I'm out of ideas.
