Bad Rod!  Bad, BAD Rod!  No woofer!

It’s on the back of the speaker, you have to turn it around.......grin

I think it's more of a muffler.

I have not soldered the the other speaker up just yet. When I do it tonight, then perhaps I will have a chance to listen for the first time. The idea with these speaker cabinets is to make resonant chambers on the back of the internal cabinet. So, there are different lengths of MDF reacting as a diffuser but also making different depth cavities to 'house' different frequencies. The external dimensions of the cabinets are 7"W X 15"D X 18"H. I used constrained damping between many of the layers of MDF, using a product that is painted on, and designed for just such an application. Sorry, I have forgotten the maker of the custom crossover at the moment, but the drivers from Denmark. Morrel, I believe.  The black walnut used for the baffles is some amazing looking wood, and I had just enough from long ago for this project. The finish is a combination of first a rub on finish, followed by a Spar varnish made for ACE hardware, followed by light sanding and then finally MinWax Tung oil finish. The sides are just the Spar varnish, as they didn't have all the deep grain for the varnish to sink into. 

 Here is a shot of part of the internal cabinet:

You have my respect for your fine work. 

 

Morel would be one possible for your drivers, but also Vifa or DynAudio. I've experienced stellar results with Dyn. Isn't it unusual that Denmark is so known for having a high concentration of quality driver manufacturers, but as far as finished boxes they've got Jamo and... who else?

I was thinking of the wrong project. These are Scanspeak drivers. It is the crossover that is from Denmark. Apparently the engineer that I built these for is a friend of the guy who makes crossovers. Internal wiring was so heavy gauge in the crossovers that I had to solder on some jumpers to solder to the speaker terminals without too much heat. I am very interested in the sound.

.....Klipsch LaScala's that sounded their best from 1/4 mile away. While I was in a rowboat, on a lake. Deep Purple, Smoke on the Water, really nice!

I am going off topic here for a reason. Note the crappy photo that I last posted. It is my camera giving up the ghost after 10 years. I am needing a really good camera for not just shooting equipment, but all the other shots that I would like to get out there. New or used, what are your recommendations? Separate lenses are a bonus.

I thought the speakers were so shiny that it was just reflections. 

[Brian_at_HHH 2,691]

@4krow, what do you have now, and what do you like/dislike about it?

 

One thing I'd suggest, if you go new, is to go with the newer non-SLRs, as the world is moving away from optical, through-the-lens cameras.  Much less mechanical bits to go awry.  All the bigger name lens systems are supported.

 

If you go used ... ignore that.  Getyourself a good deal on what suits your needs & likes.

[4krow 6,605]

Thanks Brian, I know that I have to choose carefully. 

 

Yes, the speakers are shiny enough to make reflections everywhere. The camera itself just has a hard time adjusting to different lighting when it didn't before. It is an old Olympus 560uz IIRC.

 

  Hooked up the speakers, and initial impressions are good, especially in the bass. I have them set about 2 feet from the back wall and well away from the side walls. I put them up on a short end table, expecting not very good imaging, but just to get them to some kind of height. In my room the bass extends very well down to around 40-50 hz. Anything lower must have some muscle and ability from a sub. 

 The treble so far is great. Not overdone or bright but present. The midrange is what I want to play with here. It is backed off from what I am used to at least. Having said that, my other speakers were a bit up front in their midrange presentation. Always a balance.
