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 

[swt61]

So, it's fair to say that you were baffled?

Yes, I know. OMA spells it with 2 Ls on their website.

Oh, okay, it sounded exactly backwards.

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.

[bjarnetv]

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.

[RudeWolf]

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

Desktop and mains

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 

 

here is target example:

Cool, thanks for sharing!  Hope you feel better.

[ironbut]

Looks great!

Your room treatments look pretty textbook. 

They also seem to blend in with your decor!

 

 

[bjarnetv]

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)

[bjarnetv]

After endless tweaking, the dipoles were sounding truly great - super natural and lifelike, with midrange and highs to die for...

But still, i wanted more dynamics, more punch, MORE POWER!!!11!! 

So this happened:

 

still just trying out different crossover points and targets in AL, but so far it's quite fun!

lots of energy and punch, and a surprisingly good phantom centre.

gonna try out the waveguided RAAL tweeters as well, and see if it matches the dispersion of the tractrix 200, as i really loved them on the dipoles.

 

 

(sorry for the lack of headphone posts, but my headphone life is quite dull at the moment)

holy poop - winner

@bjarnetv could we get a picture from the front of the room to the back? So standing where the TT is?

[dsavitsk]

That's an adorable cat and some decent looking cat trees.

from the archives:

right behind the sofa is a bookshelf

with a concealed 10cm RPG Absorbor behind the listening position.

I mooted the idea of traps in the room that houses my main system with my better half. Her response was definitive.

There are some battles you know you aren't going to win 

[Laowei]

Maybe not Speaker Porn these days, but back In the day these were pretty hawt. 

Altec Model 19. Woofer: 15” 416  , Mid/high compression driver: 802 , Sectoral horn: 811

Very efficient: rated 104dB @ 4 foot sensitivity. Sound great with single watt SETs, but will still take 175 watts continuous. 

Too large for my current living room, been stored in my garage for years. Fired them up today....my neighbors were not amused.

i would say those are pretty compact, so you can safely drag them into your living room

I love corner loaded speakers.

These guys are freestanding, unlike contemporary Klipschorns or JBL Hartsfield corner horns. More like a compacted Voice Of The Theater for the home.

Corner loaded speakers are cool.

 

 

[Dusty Chalk]

Oh, really?  Sorry, they had that broad, corner loaded look to them.  I stand corrected.

I mean, I was just making a random statement, a non sequitur, as it were.  Yeah, that’s the ticket. 

[Laowei]

That’s an easy mistake from that photo angle.They’re huge with a large front panel. Larger than an old Kenmore washer and dryer pair.

And they are old.

Yup, there's something oddly magnetic about those vintage Altecs. Paper down below, quality compression driver up top, crazy sensitivity... Yeah, it'll do
