[QUOTE="Peter Morris, post: 208467, member: 652"] The double 14 is 920 mm high x 500 mm deep x 410mm wide. It can still be pole mounted - just. I don't think it goes any louder than the double 12 design but because its bigger there was more freedom to archive slightly better acoustic performance. The main issue with this design is the HF horn is not available to purchase ... but it is VERY good horn. [URL="http://data.mecheng.adelaide.edu.au/avc/publications/public_papers/2008/preprint_morgans_optimization_2008.pdf"]http://data.mecheng.adelaide.edu.au/...ation_2008.pdf[/URL] [URL]https://www.google.com/patents/US20080059132[/URL] The advantage of your short horn over the band pass design I used is that you can get 2 or 3 db more efficiency out of your design. Initially I started experiment with a design similar Meyer's Leopard turn on its end, but I could not get it to work very well. The solution was to make separate band pass chambers for each of the 14" drivers and limit the width of the two exits. [/QUOTE]
