Merlin MMe - Bi-Wire or Single Wire

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!

Chadlesko, one thing I would point out, is that you experimented over such a short time frame that subtle differences in the set ups may not have been apparent. Bi-wire may very well work best in your setup, but I would suggest putting the single wire and jumpers back in for 40-50 hours of listening and then change back. In this manner, your frame of reference is greater and you will more easily distinguish differences in the two setups. Just a thought.

c, the merlin lead free jumpers are the right gauge so they allow a perfect balance between the woofer and tweeter. with them being lead free the sound will be less pointed, more expansive and tonally fuller. it may make you feel better to use the bi-wire but in the end and after a long critical listening, the jumper is best. unless your bi-wire is lead free and 15 guage on the tweeter which is doubtful.
chris, the speakers are set up for bi amping again with the right gauge wires.
i do so at home with marginal improvements.
best,
