Is it possible for the 4355 to be used with a single amplifier (McIntosh MA9000 capable of driving 2 ohm loads) by using (an) external passive crossover(s)? An active crossover would require an additional amplifier which I would prefer not having to do as the MA9000 has ample current capability for the task.

If so, can anybody recommend a passive crossover(s) that would fit the purpose? The system needs to cutoff above and below 290 Hz @ -12 dB/octave.

Just received a specially ordered equipment stand that cannot accommodate additional equipment and of course the cost of additional amplifier so the importance of passive bi amplification - if at all possible - cannot be overemphasized in this situation.

Thanks for any help.
