Merlin MMe - Bi-Wire or Single Wire

It is indeed one of the great mysteries that they set the speakers up for biwiring yet the party line is to use a single run - best to call Bobby P and ask him...

Merlin recommends single wire with the cardas jumpers and zobel network (if needed) supplied by Merlin. I use mine in this manner and they sound great. Of course, its all up to your ears. If you enjoy the bi-wire setup, so be it. But, given Melin's strong recommendation for the single wire setup, its probably worth the experiment to make sure you're getting the most out of the TSM's. Also, I suggest adhering closely to Merlin's recommendations in regard to setup, i.e. listening distance, toe-in, etc. With proper set-up the TSM's are truly outstanding speakers.

Cruz is correct. I also had a bi-wire set-up(internal) with my SE's/M's and enjoyed the sound even though I was placed 7ft and not the recommended 9ft away.
The jumper's are 15g which offer's enough impedance to allow them blend with the woofer.

I caved and experimented in every which way...ultimately decided on bi-wired with zobel network...case closed...it was close though!

Best to call Bobby on that one, he will set you right. But as I recall a conversation with him, the concern is about having the right wire gauge for tweeters, in case of bi-wire. That's why the use of jumpers is strongly recommended.
Good luck!
