Members 1001gear Posted April 16, 2015 Members Share Posted April 16, 2015 Before I goog that, ahmma guess they're 30 watters. Link to comment Share on other sites More sharing options...
Members WRGKMC Posted April 16, 2015 Members Share Posted April 16, 2015 These have wizzer cones so the frequency response is higher. Most of their speakers roll off around 4K. http://www.audio-digital.com/product/speaker-soundtech-st-12dc/ They may be similar to the 10's http://www.audio-digital.com/product/speaker-soundtech-sta-10-la/ Couldn't find the exact speaker model. so I'm not real sure what their specs are. They may be 30W speakers but compared to the other models speaker codes, the SK number seems to be random and don't signify size of wattage. They have an STA 2242 for example that's a 18" speaker at 1000W RMS. Their site is useless for speakers of components and only show a few low end cabs http://www.soundtech.com/products/pa/xl1r/ They may have discontinued the gear or had it bought out. There isn't much on line but I suspect they buy Branded speakers from other manufacturers, The 19"s look to be made by Celestin or maybe EV. The smaller ones may be from someone else. They don't look like branded eminence but its hard to know, Link to comment Share on other sites More sharing options...

Members WRGKMC Posted April 17, 2015 Members Share Posted April 17, 2015 Yea there's allot of stuff from the 90's back that pre dates the internet that's difficult to find info on. I have a SoundTech Mixer I tried to find info on because the mono send channel was dead. The company was a player for awhile being sold in music store chains then kind of disappeared. I bought the mixer used at a Guitar center about 20 years ago. It still works find and does what I need it to but by todays standards its pretty dated, lacking many useful features. There is the old fashioned way to test a speakers frequency response curve. You can download a free frequency generator program, feed it out of the computers sound card into an amp that drives the speaker then get a hand held DB meter http://www.parts-express.com/triplett-tsc-mc1-sonichek-mc-mini-sound-lever-meter--391-078?utm_source=google&utm_medium=cpc&utm_campaign=pla and place it in front of the speaker as you scroll through the frequencies from one end of the bandwidth to the other. Then you simply write down the db readings every 10 hz up to 100, then every 100 up to 1000, then every 1000 up to 20K. Then just put those in an excel sheet and have it produce a graph for you. Chances are you'll likely have nothing much below 100hz and a steep roll off above 4~5K hz like you do with most guitar speakers. A guitar amp rolls off after 4~5K so anything above that isn't needed anyway. Link to comment Share on other sites More sharing options...
