Those are really cool looking, Andy! What speakers did you use? How does it sound?

Uses 12 x Vifa BC11SG a side + Peerless Horn tweeter..
requires a sub, but when combined with one it can do the whole gammet from soft highly detailed classical or acoustic work... right up to obnoxiously loud rock.. if the sub(s) can keep up !!!

I think it works out at around 97-98 dB sensitivity, with a rms power rating of over 200w.. so they can get VERY loud !!!!

Why did you only use one tweeter per side? Are they infonite baffle, or are they in boxes? Can you post pictures of the sides and back?

Using lots of tweeters requires a second column next to the mids, and the whole extra cost of DECENT tweeters (not 20c buy-out) would make it too difficult finanicailly.. The single ni sensitivity tweeter actually works very well in the normal-large listening room situation

The cabinet is actually a U frame and very easy to make.. here is an early picture

Yeah.....I forgot. You are in AU. You really don't have access to Part Express's DAYTON ND20TB-4 REAR-MOUNT 3/4" NEODYMIUM DOME TWEETER for $4.10 US$. see: http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=275-035
Shipping would eat you alive.

If you had had that access, would you have chosen them over the horn tweeter, or would you have purchased as horn of similar value($61 US$)? Having just done the same I chose the 15 tweeters over the $61 horn.

There is also the problem of where to put such a line of tweeters, without ruining the aesthetics !!

The single Hi-eff tweeter works very well, btw !!!

And you know that to me ALL rectangular boxes are Yuck !!!!

I actually cringe whenever I see those rectangular monoliths with a row of tweeters next to a row of woofers..... it assaults my sensibilities !!!

Where's the imagination guys !!!!!

Yeah , I guess so.. Send em here, I'll rebuild those BOXES for you

Or perhaps, I could say that you obviously weren't thinking when you built them like that, just operating on automatic.. ;-P

just like a NORMAL person would !!!!

Oooooo... I see a war brewing here ;-))
