MW Audio MT-4121: .75" Soft Cloth Dome Tweeter Great overall sounding tweeter for any home audio application, but main design is for many Acoustic Research speakers. Many have stated that the original tweeters have been the weak part of their speaker and now we have a great upgrade to the old paper dome, phenolic dome and the "newer" AB Tech version of the 1200084-1 tweeter. We believe our MT-4121 tweeter surpasses the overall tonal quality of all these older AR tweeters. Note that the terminals are on the backside of the tweeter, so some rewiring inside the cabinet may be needed for the older front wired versions. Most models use a 4 ohm version tweeter, but some also use an 8 ohm. 8 ohm models: - AR-2ax: For the later version with the .75" hard paper dome. The earlier version has the 1" phenolic 4 ohm tweeter. - AR5 - LST-2 4 ohm models: - 1200084 is the newer replacement. - 200029-1 used in AR9. - 200011-1 used in AR11, AR11B. (You can add a .1mH coil in parallel if wanted for these crossovers). - 1200029-1 used in AR58s, AR90, AR91, AR92. - AR10pi - The hard phenolic 1" dome tweeters used in AR2, AR2a, AR2ax (early version), AR3, LST and more. - The hard paper .75" dome tweeters used in AR3a and more. Specs: Freq Range: 1200-20,000 Hz Fs: 1200 Hz Power Rating: 75 Watts / 150 Watts Max Impedance: 4 or 8 ohms Re: 3.9 or 6.3 ohms Sensitivity: 86 dB Voice Coil Diameter: .75" (19mm) Magnet Weight: 11 oz (310g) Face Plate: Aluminum Dimensions: Outside: 4.75" (120mm) Cutout: 3.55" (90mm) Screw Hole Size: .315" (8mm)
