I would love to see your 401. And agree that the slate would be a very effective, as well as beautiful baffle.

This is it. The main profiles were water jet cut. The main thickness is actually two slabs bonded together so there is a bit of damping.

The 401 used to be notorious for rumble, but that used to be as a result of the primitive chipboard plinths. Screwed hard onto a slate plinth it is silent.

Now all the plinths and baffles I've seen (including mine) are the grey sedimentary slates. There is another type, which is the product of ancient volcanism, and under extreme pressure and heat becomes a gorgeous green colour. I have no idea what the internal damping of the two types is, but I'd like to experiment with the green stuff, if only for the look.

The plinth above has been NC machined, and you can do much more adventurous things that way - like the superb looking chamfers.

PS: That's a solid slate baffle.

It's called aptly "Monitor". I can't find a price but if I ever win the lottery...

I thought that said "solid state baffle" and was like :blink:

Finns know their speakers. Cast aluminium chassis, twin Class-AB amps and a metal tweeter that sounds anything but metal. The minimum diffraction enclosure seems to be working as I feel the imaging is as good as the coax LS50ies. Despite playing below 40Hz very well a digital crossover sends everything below 60Hz to MiniDSP 2x4HD which room corrects the signal before it's amplified by a IMG Stageline STA-800D amp for subs.

My next stop is swapping the miniDSP for an Mac Mini to run digital frequency and phase correction.

I can recommend Audiolense for the digital XO and room correction, though you would need to run bootcamp to use it.

It´s not the most user friendly program, but it works really well once you figure everything out, and integrates everything really well.

My idea was running Reaper to do routing and apply the necessary correction through AU plugins. Will need to learn to use Smaart tho.

Being stuck at home while sick does have it's benefits since i recently acquired some RPG modffractal diffusers.

I have dragged the tv into the living room and connected it to the media-pc for a day dedicated to trying out different room correction and target settings.

Different cycle length on True time domain settings sure do change the sound a lot.

just a single cycle in the midrange can change the sound from being forward and aggressive to smooth and laid back.

serious room correction sure is fun :D

Thanks dusty! 

It's just the man flu, so nothing serious.

@ironbut 

i've tried my best integrating the treatments as feature of the room,  so while there is no escaping the fact that half the living room looks like a recording studio, i quite like the look myself.

it helps that the diffusers are really well made, so they look more like a piece of art (if you like wood that is ;) )

i was pretty anxious how much of an effect the diffusers would have on the overall sound, but in the end they thankfully worked just as i had hoped they would, by really opening up the "stage" increasing the depth and focus of the soundstage, and overall just smooth things out.

 

if i increase the TTD cycles (how far ahead of the impulse you ty to correct) it truly turns into a window into the recording where the acoustics of the recording "replaces" the acoustics of the listening room.

Right now i am trying out the middle ground, with just enough TTD cycles to increase the soundstage while retaining some of the liveliness and "punch" of the room.

(too much TTD room correction can make things a bit too smooth sounding)
