[QUOTE="thylantyr, post: 3058826, member: 560358"] Go to the Selah forum {audio circle} and see if you can get some user testimonials on that speaker. Dig up some dirt before you tackle the project. This is a complicated design. Ribbon + dome midrange + seas midwoofers. You can simplify this. You can use a bigger ribbon, maybe the $125 or $300 Fountek, implement an active steep crossover, slope LR4 or LR8, and use those Seas mids, but I'd still chose a pair of PHL1340 midwoofers over Seas. The Fountek NeoPro5i is nice. Expensive, high sensitivity of 102dB. // nice // [URL="http://www.madisound.com/catalog/product_info.php?products_id=1557&osCsid=9b5535d5459aaa71a08d265c0f3ed7ea"]http://www.madisound.com/catalog/product_info.php?products_id=1557&osCsid=9b5535d5459aaa71a08d265c0f3ed7ea[/URL] pics found in cyber; [URL="http://home.pacbell.net/lordpk/phl/NeoPro5i-1.JPG"]http://home.pacbell.net/lordpk/phl/NeoPro5i-1.JPG[/URL] [URL="http://home.pacbell.net/lordpk/phl/NeoPro5i-2.JPG"]http://home.pacbell.net/lordpk/phl/NeoPro5i-2.JPG[/URL] [URL="http://home.pacbell.net/lordpk/phl/NeoPro5i-3.JPG"]http://home.pacbell.net/lordpk/phl/NeoPro5i-3.JPG[/URL] The $125 Fountek NeoCE2.0 is good too.

[URL="http://home.pacbell.net/lordpk/temp/IMG_17431.jpg"]http://home.pacbell.net/lordpk/temp/IMG_17431.jpg[/URL] You have to figure out if you like ribbon tweeter sound or dome tweeter sound. If you like the ribbon tweeter sound, the Fountek brand is very nice for the money. Rick @ Selah uses it alot in his line arrays and the composite ribbon design is more robust than the designs using an aluminum element, ie Raven or AC ribbons. There really is no need to look at those expensive ribbons. On the other hand the Raal is very interesting, those are more unique. For wider dispersion, the small ribbon is needed but they are crossover frequency limited. That's why the Selah center channel you like needs a dome midrange, because that small ribbon can't be crossed over lower and the Seas midwoofers are just poor performers in the higher crossover frequency range. In other words, Seas Excel is high end drivers, but they are not forgiving and don't offer as much design flexibility as the PHL. If you use the larger ribbons, you can lower the crossover frequency but a larger ribbon has weaker vertical dispersion so you need to aim the tweeter towards the listener to get the sweet spot. Catch 22. The LCY ribbons look interesting as they have wide dispersion like a dome, claims of 2.5khz crossover can be used, easily integrated with dual PHL mids. [/QUOTE]
