| 49Hz To 52Hz will be your peak, so the best you could hope for would be 3 hz below that flat with a perfect tuning of your length of your horn and back chamber of your box housing your woofers. If you shoot for the free air low res of your design, of your horn you will have to eqaulize at that peak to remove it. So you want at least 40Hz to 35Hz free air cone's to elimenate peaks, shooting for 42.7Hz with your calculations. It would seem you would be better off also with a 8inch input instead of 7inch witch you had mentioned, 8 is the norm in the industry for input of mid bass horns. Altec 515 B and EV 15W Are the beast's that you need they have very low res in the industry below 30 Hz. If you are interested i have 4 matched like mint altec 515b Woofer's for sale, they would be perfect for this project. If you are interested i will post picture's, they are in cardboard boxes right now, packed away. I also have a pair of stevens early woofers that have 35hz low res that would be perfect for a single driver horn, these have hugh alnico magnets larger then the altec very good qaulity. Value for the steven's $125.00 each + shipping. Preaching Horn Religion Msaudio |
