    Hi. all. I have an amp with Output Power of 2x60W rms (4 Ohms) or 2x50W rms (8 Ohms). Taking only one channel. I have a bass/ midrange 12'' speaker rated at 8 Ohms and a tweeter also rated at 8 Ohms. If I was to connect them in Parallel ( Making them both now 4 Ohm units. ) Would this damage the speakers in any way? This next bit is nothing to do with my problem. But any ideas on a mid-range or tweeter that covers the missing range Here -.
    The watts of the speakers are 200. With a range of (Hz) 30-4200. And tweeters 150 watts. 4.5kHz-20kHz ( Just in case I pop on a bigger amp.) I'm going to be using a crossover in each cabinet.

    If you use a proper crossover (that must itself have a nominal 8 ohm impedance if your two drivers are 8-ohm units), the impedance of your enclosure will remain at 8 ohms. In effect, the amplifier only "sees" the 8 ohm load of the crossover. With one enclosure per channel on your stereo amp, you will be operating safely at 2X50W RMS. If it's a two-way crossover, you won't be able to properly and safely add a midrange driver. You'll need an 8 ohm 3-way crossover if you wish to build a 3-way system.

    Thanks for the reply. I do have a 2 way crossover on order for each channel. Cheers.
