I wonder whether having two woofer drivers facing each other creates an even faster wavefront than otherwise possible from front-facing woofer drivers in a conventional cabinet design. Do the mid-bass drivers flanking the AMT ribbon have a rear cabinet opening for accommodating a backwave emission?
There are a few images on the Fischer & Fischer website. SN/SL 1000.1AMT appears to have ports on rear of the bass section (not the subs). I would imagine the midrange drivers have semi-open back cabinets as per their usual design, but it’s impossible to see the rear of those sections on the website as the speaker is constructed and the sub units obstruct the view.
I can't remember the name of this type of woofer config, but coupling them like this has a greater effect than if they were both there but not face to face. The 7 inch mids are open with tuning material in the tunnel. There is also material on the front face of the sub cabs to disperse the wave where the mids will have a back wave. The midbass on this speaker will. Be ridiculous. Drums will be bonkers..
@@OCDHIFiGuyThe bass configuration is called „bass compression drive“. It was first introduced by F&F in 1999 in their SL1000 model, which I owned for 16 years before I replaced them by the SN 770.1amt in 2016. The bass configuration worked wonderfully in my room, however the SN 770.1amt is the superior speaker. Unfortunately, the SL1000.1 is too large to fit in my room sonically. Anyway, slate is the best material to build speaker cabinets. Thomas Fischer also delivered the plinth of my turntable from german company Transrotor. This model, the La Rocchia, sounds great due to the slate plinth (and some other design featues…). Greetings from Germany!
I found it. It's called Force cancelling and provides strong clean sound with no cab resonance (slate ain't gonna resonate anyway) but it also means the cones move little if any. It's kinda like dual opposed in that regard except the dispersion pattern is different with force cancelling. You get a all direction throw. Man i wish i could travel, id love to put on some dubstep with those cannons. 😄
@@OCDHIFiGuy ..no that super easy to understand. The thing is that your clip is just a teaser - to me that's no value (as we get constantly flooded with teasers...)
