Well I am now doing what I said I was not going to do. http://www.audiokarma.org/forums/showpost.php?p=1467681&postcount=137
Screw it - these are MY speakers and I don't like the sound of them one bit. I would have sold them but one one of the intricate grills fell apart on me so I don't think they are really worth much anyway. I will sell the drivers and use the basically worthless cabinets - might as well enjoy them. The previous owner (unfortunately deceased) would HIGHLY approve of what I am doing - he was an EE and a tweaker.
Take a look at the Duffenators project for more details as I am doing the same thing http://www.audiokarma.org/forums/showthread.php?t=136160 only using a different cabinet to start with. I will also be using the 2235H woofer.
Here is the start of the project. I spent about 30 minutes disassembling the cabinet down to the shell. Mine might be a Monday morning or Friday afternoon special but this thing was barely held together with a few brads and about 30 drops of glue. No wonder they were rattling with the 2235H loaded to see what they sounded like. No effort what so ever was made to seal these cabinets or make them ridged. They even used particle board (not MDF) on the rear and bottom. They will be radically beefed (think 1-1/2" walls) up and braced over the next few weeks.

We see that 2452H-SL on PT-F95HF hidin' back there....
Yes you do - that wonderful thing (and what a wonderful thing that is) is my pain in the ass reminder to geterdone! Getting it done is happening big time right now. After hearing Duffs speaks I am in need of good sound.

A trick I used in Music Appreciation class -- had the labels and colors in my notes and memorized them. Prof never caught on 'till I told him once the semester was over.... ;)
 
Can someone explain what is going on in the discussion of colors and numbers here? I assume that it has something to do with the records in the back.
 
'2452H-SL on PT-F95HF' -- is that about the record, and if so, who knows record serial numbers? That's even more obsessive than I am. Or is it something else? Or is it simply made up?
 
That's the compression driver and waveguide that is the heart of this speaker design. It's sitting on the floor in the first picture.

Oh -- it's two different topics. Record labels and drivers. Knowing driver numbers I understand. But knowing record serial numbers - no.
 
Yep - 2 different topics

Ultra high end drivers and silly $5Black Sabbath records. Ain't this whole music stuff fun. Never know what you will see. Keep watching lots of fun about to happen - the old DC to daylight thing.
Try this one on for fun - a lot easier than the last one.

Going to make one crossover tonight. And patch up one cabinet tomorrow to use the waveguide and add some ports. Maybe I can get over to the 'lab' on Friday. It will be fun to see how much the Vals cabinets 'sing' with a real woofer installed and the cabinet properly loaded.

:lurk:



Thamks for mentioning this title (a shame only one chapter is online), I enjoyed reading and seeing a lot of Sacks' work (the GF is a psychologist) already, didn't know this one yet.
Check out his speech on TED http://www.ted.com/talks/oliver_sacks_what_hallucination_reveals_about_our_minds.html
Some people hear musical notes as colors... it's a surprisingly common form of synesthesia. See Oliver Sacks' book Musicophilia.

Just sayin'...

This might be a fun thread on it's own - name that album only seeing the center of the cover. This one should be a bit harder than 2112 (my all time favorite Rush album - and I have had this copy since high school.)

Made some real progress today

For fun I decided to try a minimally modified cabinet - just enough mods to allow the new JBL's to bolt in. In a half hour or so I will build a crossover and then fire it up!
