DONTO'S

Donto's Get-Away! is just that, a place to escape and relax listening to my favorite music or viewing movies. My Audio Room is 14' deep By 18' Long. The Heart of my system: 9 Power Amplifiers: 5 are Parasound Amps all Designed by Audio/Electrical Engineer, John Curl. (Wonderful, Dependable High Current Amps) and 4 each DIY Mono Set Amps in 2 chassis. Pre-amplification is also by Parasound. P/HP-850 (Direct Coupled Output) with Phono Stage My Main Front, Left/Right Loudspeakers are a pair of POLK Model 12c "Real Time Array" R.T.A. 12c Monitors........................................................ I purchased these 12c's New in 1987. 25 years old!...However: I Love these 12c's. Deep Tight Bass (17 Hz to 26,000 KHz), They deliver a huge detailed transparent soundstage and they represent vocals (Both male and Female) with such a "You are there realism". Old Speakers, However: Very Well designed (Thank you! Matthew Polk!)..... I have upgraded some of the compoinets in the crossover units ( More to upgrade)..... But the drivers all remain the same. These 12c's really love High current Amps and can handle up to 500 watts. 4 ohm impedance, max output level is 118db with an efficiency of 92db. Not bad for a Loudspeaker designed over 21 years ago......................................................................................... I tried various Mid/High frequency horns and decided on a pair of JBL Horns............................................................................................................I did not want to physlcally modify the RTA12Cs cabinets to incorporate the JBL Horn Drivers. I made 2 separate cabinets, that fit atop without fasteners to the RTA's cabinet. The JBL drivers have a 12 db per octave slope and frequencies below 4500 HZ do not pass to the JBLs............................................................................................................. This system uses 3 each seperate Subwoofer Units.................................... Cabinets are Home Built fitted with 15" Subwoofer Drivers and wired with hand built LOW PASS Crossover Units. Bass is Extremely Well Controlled (Not Boomy) Fast Tight and can and does rattle windows/doors and anything loose in the room.
