Tripole surround Clone #2

[pjpoes]

As I had mentioned last time, I had another pair of enclosures from the M&K bankruptcy buyout which used larger drivers. I think they were meant for a 6" stamped steel frame midbass, their flared square frame dome tweeter, and a pair of peerless or vifa full range 3" drivers on each side. Since the tweeter cutout really wouldn't fit a normal 1" round dome, I decided just to buy the over priced (IMO) M&K tweeters off the web, and at closer examination, I would say they are made by Peerless (The dome/coils look identical), and appears to be based on peerless's own flared tweeter, but I believe made to a lower price point. I chose a Vifa Logic BC14SG69-04 truncated 5" midbass driver, which fit very nicely into the hole, as you will see. For the side drivers I chose the new Peerless 3" full range aluminum cone 830986, which I truly love.

The crossover is a simple 2nd order butterworth design. I kept things simple since I didn't want to spend too much on the project, over complicate the crossover, or reduce efficiency too much. Additionally, the midbass doesn't measure great in its upper range, and would require a notch filter and 3rd order crossover to truely flatten things out. I listened both ways and decided it wasn't worth the hassle and expense. I also didn't account for the coil losses of the 20 guage inductors, as I used 12 guage cfac's durring my testing, and will probably pad the tweeter down a bit more later on. However, it really doesn't sound that poorly balanced, just not as natural as my reference.

I will post the crossover schematic I used in this one later if people want. Again, I'm a bit surprised there is no interest in a good surround speaker design like this. This is a solid inexpensive surround speaker that we know would have sold for ~700-1200 dollars a pair (Considering the price of M&K speakers and the improved drivers in this design). Even without the enclosures I got, these could be built pretty easily. I weighed them, since they are being wall mounted, and are around 15lbs each, so pretty substantial little speakers.

For all the images it says "unavailable", could you fix them?

apparently flickr doesn't allow you to host images from flickr on other webpages without linking it back to flickr. However, when I put the code they give me into this, it doesn't keep it as an image, just as the script. I'm not sure what else I can do, the images are too large. Lets see if what I have done worked, if not, then I will try another method. Sorry for this.
