In Reply to: RE: Why would single driver speakers benefit from bi-wiring? posted by genungo on July 18, 2014 at 14:02:16
One post for midbass
One post for xover to tweeter and then tweeter is connected to the binding set on the top of speaker.
Tweeter has a 24 db xover between it and the amp input.

The topside speaker terminals are internally connected to the primary speaker terminals, as far as I know.I would have thought to simply connect the bi-wire pair to the double terminals on back, per manufacturer's suggestion. The manufacturer, rightly or wrongly, thinks that bi-wiring his speakers help them to sound their best.

The Laura is touted as being a crossover-less speaker and is (supertweeter or no) essentially a "single-driver" speaker. The supertweeter contributes very little high frequency info in this design and one wouldn't think that bi-wiring would do much of anything, but the proof is in the listening.

I've probably heard the exact same unit you have, from none other than Mr Bankert himself. Spent a good deal of time with him and his offerings over many years.
Yeah, but disconnecting the supertweeter entirely barely changes the sound. It adds a slight haze of sparkle and sheen. The supertweeter uses a 24db high pass filter at 9 khz, woofer extension is 10,000 hz. I really wonder how much difference a separate cable will make. I'm using jumper cables now but, as I've said, I am going to try bi-wired.You say that you have heard this very unit? Was Sonist Audio in Idaho at that time? Maybe you can advise me, because I noticed that the inner folds of the speaker cabinet are lined with sheets of 3/4" grey acoustic foam and I need to replace the foam sheets in one speaker. Can you recommend a certain type of replacement foam?

Royal is an italian company as I recall. I have no idea as to the source of the foam you mention.
Parts Express sells foam in many thicknesses, I hope it works likes the original stuff.

Royal Device specifies the exclusive use of its proprietary bi-wire speaker cable with all of its models to ensure their maximum profit margin. :)
