LSi9 wiring connection question

I have recently replaced my front R/L LSi9's with a new set of Tyler Taylo Reference Monitors, but my receiver cannot handle a 4ohm center chan. Would it be possible for me to hook up both LSi9's in series, as my center channel, to create an 8ohm load?

I guess I should ask, would it be safe to do this and still get the great sound I've been enjoying from these speakers the past couple of years?

Thanks

    You can wire both speakers in series. The positive terminal of the amp gets linked to the positive on speaker A, then the negative terminal from the amp to the negative terminal of speaker B. Now you need to jumper between the remaining terminals on the speakers and you're done. By doing this, you increase the effeciency of your center channel by 3 dB. In other words, it might end up being too loud.

    If you lay the speakers down to look like a center channel, you'll get the same d'Appolito dispersion effect.

    if you wire the speakers in series, you may end up with the second speaker in the signal path being crossed over, it happens in car, if you series a component set. ive never tried it in home

    The receiver is a Technics SA-GX710, it was one of the older Dolby Pro Logic receivers from the late 80's. It can only handle 4-8ohms on the Front L/R Chan, and 8ohm on all the rest.

    Don't I have to worry about back electromotive force causing distortion? I know that you don't have to worry about this when you are dealing with dual voice coil speakers, but LSi9s are not DVC.

    Thanks for everyone's comments.

    Am I worried over nothing?
