Marv, if your room limits how far away from the back wall you can get with your speakers are there any options that are more forgiving/allow you to place pretty close to the wall?  Or, is something like the BK-16 going to really start to suffer if you push it too close?

Yeah, well, you know, that's just, like, your opinion, man.

You should be OK with the BK-16 up against a wall since the horn does help direct a significant amount of mid to high bass forward (and low bass is non-existent). In other words, it's much more immune to the muddy bass effect when placed against the wall because of the directivity of the horn. I pull them out for better stereo imaging. The stands in my opinion are necessary.

Interesting. Why do you think stands are a must?

I have the Fostex BK-12 cabinet (built myself, didn't get the kit) and I was thinking about sitting them on a piece of plywood and isolation spikes. I suppose building a pair of angled stands wouldn't be that much harder.

  • Need to lift BK-16 off floor to prevent mid-bass bloat, unless strong mid/upper bass is your preference. The floor will reinforce the bass. Placing against the wall (in the context of Ship's question) will also reinforce the bass.
  • I can't say for the BK-12, which is different from the BK-16. It also depends on the drivers used which will result in varying responses.
  • Stands are not a necessity. Angling is not a necessity. Lifting the BK-16's horn up from the floor is a necessity IMO. Whatever method is used to lift the mouth of the BK-16 horn up from the floor should be fine as long as it's sturdy.

I've been looking into local options. Madisound's price for the kit is very reasonable.

A friend that owns a furniture company says the cost savings to route a box the size of BK-16 wouldn't be that much. And the larger enclosures like Kirishima or Victor will not be cheap.

The BK-16 isn't viewed that favorably on DIYA (most saying it's a very old design), but they commenting on it without EQ.

purrin do you have any thoughts on EnABL? It seems like voodoo to me... and I'm not too trusting of the guy that came up with it.

There are better box designs than the BK-16. I believe the box was meant for an older driver, the fe165 which is no longer available. It just happened that the fe166 sort of worked in it. The FR of the BK-16 is very midrangy with a fairly 3db broad bump around 1k.

The EnABL stuff definitely smells like voodoo. I would like to see measurements.

I think I am going to start a Vulcan when I return to town. Being in the woodworking industry as well I can certainly agree that the fostex kits are well priced.

I'm not sure if you're planning to EQ or not, but from my research it seems like many people dislike the 8" Fostex drivers, saying they're too shouty.

I believe he had recommended the sigma driver with this and a tweeter, I was also thinking about the cornscala. Are you still leaning towards the Victor?

EQ and follow this thread directly, I have a lot to learn but look forward to starting the process.

I am more than likely just going BK-16 since I don't have a large enough room for Victor and I plan to EQ them. Also I feel more comfortable knowing there are some baseline EQ settings for the BK-16 (though I do plan to measure them) and that I can bug purrin more shall noob questions arise :&

But I'm probably only going to start this in the fall.
