Excellent photos! I'll bet the system sounds outstanding. Congrats Rev!!!
-
You may notice how well lit the LP is on the turntable. That's not from the flash on the camera....
Not pictured is a small adjustable spotlight which aside from its obvious purpose, casts a reflection onto the ceiling providing an interesting aesthetic bonus!
Rev said that feature really grabs the attention of his kitty. :D
-
Thanks everyone, great pictures Pepe.
-
Wow! Nice Rev.
-
Very nice. What kind of platter weight/clamp are you using?
-
the gear sounded great. i'm definitely modding my al-iii's so i can have the front-firing woofers. they were badass. and al, i'm glad to know that the cat stares at the ceiling reflection like i did haha
-
Apparently these will be well worth hearing when I get stateside. Congratulations on a job well done, Rev!
-
Looks like a JA Michell clamp. I used to have one and was very happy with it. There is a little felt washer that goes under the record and the pressure from the clamp is focused on the outside of the ring. Great cheap upgrade and you don't have to worry about the weight.
-
Great sounding rig!

Here are some crappy photos of the system as it stands now. I built new DIY speakers recently and moved them against the longer wall for better imaging. I took the posters down and did some painting. I ordered new acoustic foam panels to place behind the ribbons. I'll take a few more pictures later when the walls are done.

What drivers are you using for your DIY build? Do you have a build log somewhere in the great wide interwebs? They look great! OB-line arrays from what I can tell.

No, i didn't really document this build. I think I did for the old ones somewhere on this forum. They use 48" carver ribbons and 8" jl audio subwoofers. Using an active crossover that right now is set at 175Hz. I had this set at 150Hz on my old pair but I noticed a slight hump so I moved them up a bit.
The cabinets that house the JL's are angled upwards which I found improves the bass tremendously. They are non-ported. The ribbon baffle is sitting at 90 degrees. They are connected using heavy steel L brackets and wood shims. These shims will be changed to hard rubber in the near future. The baffle isn't actually touching the cabinet but enough vibration is coming through on extremely bassy music (like Torch Song) that the baffles are vibrating.
The baffle bracing is made from 1/2" square steel rods with hard rubber ends/brackets i made/designed so they could be mounted to the wood without the metal touching. The ribbon grills are taken from the old speakers, I plan on making new ones that are longer and rounded at the ends. Also i need to look into better spikes. I'm currently using hockey pucks in the front to achieve the 90 degree ribbon baffle angle.

I've seen people do sound-treatments behind posters before. Printing on acoustically transparent (semi acoustically transparent is fine) material is available, and you can then put 2"+ of damping material behind it. There are a bunch of posts across the interwebs of people building these. It's an awesome treatment without the fugly appearance.

Nice pics, Rev, I imagine it sounds pretty smokin' too!

Insanely cool

haha you said shim
-
Lookin good and sounding better!!!!
-
Very nice Rev! Interesting observation on angling the subs.
-
If you are concerned about vibration into the ribbons, why mount them on the sub boxes at all? Surely from 175 Hz down, you won't lose any imaging by moving the sub boxes out a foot, will you?
-
Beautiful. I wish I had the skills to build things like that.
-
Thanks everyone, like i said earlier, hopefully I can take some better pictures. Yes, the plan was to make a single speaker. I could have made a separate panel just for the ribbons but what fun is that? The alignment of the woofers (subs) and ribbons in my old pair seemed to be perfect so I went with the same concept. The upward angle of the boxes do alleviate some issues but placement is still a big factor, like the ribbons, when it comes to imaging. The sweet spot is very small.
-
Hey all - I had to move pictures around in my photobucket so the pics of Rev's system disappeared. Will repost them later today.

Had the opportunity to give the new set up a listen last night....
Pretty darn sweet!

"I'll take a few more pictures later when the walls are done."
Ahem..and we want some nice close ups of that turntable
-
I haven't really done anything with that room yet. I'll take a few pics of the "fisher price" turntable as Pepe calls it.

To be accurate, I called it a Playskool turntable. Fisher Price would be a step or two above that. >:D
