Cornwalled Posted August 25, 2002 Share Posted August 25, 2002 Hello, Has anyone heard of the Altec Lansing 990E compression driver? Anyone know what horns it would mate to, and what the crossover point and slope is for it? Any help would be greatly appreciated. Thanks alot, Jon ------------------ markvi82@hotmail.com 1981 Cornwall I's Yamaha DSP-A1000 integrated amp Soundcraftsmen PE2217 preamp equalizer Marantz CD Player Pioneer turntable with Audio Technica cartridge Denon cassette deck Quote Link to comment Share on other sites More sharing options...
TBrennan Posted August 25, 2002 Share Posted August 25, 2002 Sure you don't mean 909? The 909 is a 1" throat driver used from 500hz on up. Or the 290? 1.4" throat. used from 500hz on up. www.chicagohornspeakerclub.org Quote Link to comment Share on other sites More sharing options...
Cornwalled Posted August 25, 2002 Author Share Posted August 25, 2002 Hello Tom, I looked at the driver again, and it is indeed a 990, it's a beast, weighs almost 20 pounds! There is a sticker on it that says "Giant Voice", and it's a 4 ohm driver. Here is a link to it on eBay that I forgot to post before: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1375754304 Do you think this is some large format PA driver intended for outdoor use? Thanks, Jon ------------------ markvi82@hotmail.com 1981 Cornwall I's Yamaha DSP-A1000 integrated amp Soundcraftsmen PE2217 preamp equalizer Marantz CD Player Pioneer turntable with Audio Technica cartridge Denon cassette deck Quote Link to comment Share on other sites More sharing options...
TBrennan Posted August 25, 2002 Share Posted August 25, 2002 Jon--That's a 290, look at the label again. The transformer and cover have been removed. This is a phenolic diaphragm driver good down to 300hz on the right horn. Midrange only, very poor highs. Use on Altec multi-cell horn or 1.4" throat horn of your choice. 1st order crossover at 500hz should work fine on 500hz horn. Quote Link to comment Share on other sites More sharing options...
