crossover and impedence question

[dvd_diyer]

I am building some satellite speakers and had two questions. First can I add a 4 ohm resistor to a pair of 8 ohm speakers in parallel to make it act like it has an 8 ohm impedence? Secondly I designed the enclosure to play to about 80 hz but would I need a low frequency cutoff at 80 hz to protect the speaker? Any input would be helpful.

1) basically yes you can, but a very bad idea, should only
be done if you really have to, bass tuning will be very poor,
and you will waste half your amplifiers power.

2) If its a sealed speaker basically no, reflexed probably
yes, but it depends on how hard you will be running them.

1. No, like sreten says
2. Probably no, like sreten says but

Tell us a little more about it so we can help
