my DIY HT upgrades - in progress

[Anubis]

I almost asked what your handle was on AVS...then my pea-sized brain saw that "sibuna" backwards was...yeah.



(Looking good!)

lol
first coat of duratex done on the fusions

 

[Anubis]

2nd coat done - looking good. Tempests tomorrow

 

[Anubis]

X-OVERS
Tempests X-overs - nothing is soldered yet

Fusion - only got 1 done. Split boards as i could not seem to get it to all fit on 1

-----

Tempests are finished - i wish all paint was as easy and forgiving as duratex - so easy that i decided to repaint a lamp as well while i was down there with it LOL

Also got one of the Xovers for the Fusions all put together - i cant do the 2nd one because i didn't order enough Barrier Terminals. i didnt plan on doing split boards so i would have had enough originally. Ill prob just take them from the Tempest boards until i hear back that those are laid out correctly

and we have sound

[iRONic]

Massive props to you!

 

[Anubis]

i tested & soldered the xovers for the fusions last night. picked up some stuffing. hopefully ill be able to put them together today

 

[Anubis]

and we have some tempests!!!!!!!!!!!
The Stuffing begins

X-Over Placement

One done

BOOM

datass

 

[Howard]

Well, how are they?

 

[ManBearPig]

x2

Excited to hear impressions. Take measurements n stuff.

 

[Anubis]

i didn't get a chance to give them a proper listen last night as i didn't get the last one together until almost 11, and at that point i didn't feel like moving them out of the basement and up 3 floors. Ill do that today. I did run some stuff through them from my phone and they sounded pretty phenomenal. Ill prob move them tonight and give them some proper listening

 

[purbeast0]

dude no clue how you could build them and not listen to them haha that would be killing me. that is awesome though man they look good.

 

[Anubis]

i did listen for about 45 min but i was exausted and my phone/gmusic was being stupid and i couldent play the tracks i wanted to. so i siad F it and went to sleep. This evening ill spend a lot of time with them.

Heard back from my contractor friend about the TV stand as well, Hes been super busy with work and other stuff, he said he will have some info for me this weekend

So i carried them upstairs today, 3 flights of stairs, these things are not exactly light weight, Had to move some stuff around to make room, if you make note of the first pic I posted ion here you can see what i moved.
Old speakers and Sub moved out as well as the random chair (which is super comfortable BTW) Dropped down the Tempests and hooked them up. Ran them from the XPA-3 for most of the time

Initially i just tossed them down to confirm everything was working

Without the flash the woofer pretty much vanishes into the cab, not sitting flush is a non issue

Propped them up a lil after a bit as they are sitting really low currently. Plan is to raise them up almost 2 feet by placing them on the sub boxes when those get built, this works for now

Ran a wide spectrum of music through them, Everything from Classical to Dubstep. Good god these things can just scream at you. They play loud, extremely loud and clear. Running reference could get painful fast. I sit like 8 feet from them and was running them in 2 channel stereo set to large. these definitely will play lower then they are speced. Ill have specs next week but they handled http://www.youtube.com/watch?v=3Gb3faOzvBk perfectly fine. Same song on the opening scene in Art of Flight. Obviously didn't hit as low as a true sub but these would not disappoint as a 2.0 setup when played loud. Same with tracks from the Tron soundtrack. Was rocking some Dylan and someone who was here made the comment that it sounded like we were in a coffee ship in the 60s

Lows play low, highs play high but not too bright. on some tracks that hurt my ears at high volumes with other speakers these just sang along without the pain (assume because of no distortion)
Mic comes next week so no measurements until then. will be really interested in what the readings say.

I should get the fusions together this weekend - i wont have the things i'm waiting for from PE until Friday.

I see that EricH has been updating the sub flatpack info i can not wait!


I'm also gonna need to build stands for the fusions, im thinking sand filled PVC tri pole

So i may have just experience pure audio nirvana. Was playing some stuff today, the clarity is incredible. pretty amazing hearing things in songs Ive listened to 100000000 times and picking up things i hadn't before. These speakers actually give my Grados a run for clarity.

Back on the nirvana comment i actually fell asleep listing to music at near reference in a tiny room. That may strike some as very odd, but to me its not. the loudness is a non factor when its as clean as the sound coming out of these speakers. i closed my eyes and felt like i became one with my sofa and just drifted away

fire up Mozart K.626 :biggrin:

Distortion can make things sound louder than they actually are, or make them sound bad, but physical pain is usually caused more often by compression (loudness war) or clipping.

Please educate me and provide links and substantiation.
Only sound pressure can cause pain, distorted, compressed, clipped or not.

 

[Anubis]

well look what i have here

Sorry, I forgot to add the qualifier at "reasonable SPLs".

I make the statement based on personal experience with some songs I've listened to while watching the peak and VU meters. Certain songs induce headaches and pain right away, even at the same apparent SPL.

I am certain some corresponding anecdotal experience is out there, if not peer-reviewed studies.

EDIT:

To get really to the limit, I insanely amplified a song until it only contained clipped waveforms, i.e. amplitudes of −1 and 1. The result has a RG gain of −19dB and is painful to listen to even at low volume(4)

On the contrary, Groove Armada - The Remixes (amongst others) is an album that can be listened to loudly without any pain or fatigue.

Curiously enough, you ask for substantiation and then right away say that my statement is false. Why?

 

[Anubis]

interesting stuff.....

anyway - no EQ - No Sub

 

[Aikouka]

Is that good or bad?

 

[Anubis]

its a very nice start

 

[Howard]

1/24th octave smoothing?

 

[purbeast0]

anubis do you have to have omnimic hooked up to a laptop while it's doing the test? or can it do the tests and then you hook it up to a pc and it exports the results to the pc?
