Open Baffle Speakers - Front

I had a very large sheet of 18mm particle board which had been sitting around for years. Also a pair of titanium domed tweeters and 2" domed mid-range surplus. What to do with them? With the addition of a pair of cheap but very robust 10" woofers and a 2nd order Xover (600Hz & 3.5kHz) I thought a may knock-up a pair of OBs.

I allowed one day to build these from scratch and with the assistance of some massive angle brackets and a few meters of darcon here is the result. That total height and depth of the speakers is covered in two thick layers of darcon leaving only the woofer rears bare.

The woofers are stiff and require many hours of play to get them to full performance. But the speakers have an excellent sound stage bright mids and highs. Bass is OK but not deep.
