Silver Iris OB 15" Augie

The Silver Iris OB 15" Augie bass augmentation driver is specifically built to provide low frequency reinforcement for the Hawthorne Audio Silver Iris 15" coaxial speaker system. It can however be successfully implemented in a variety of applications including dedicated 2 channel and home theater systems. It mates well with nearly any main speaker and provides articulate bass reinforcement, which increases the realism and impact of nearly any system. The 15” Silver Iris Augie was well reviewed by Dick Olsher of “Enjoy the Music.com” Following is an excerpt taken from his review of the 15” Augie. “It seems to me that many listeners confuse bass weight with bass extension and opt for a subwoofer when bass weight is lacking. The problem typically lies in the upper bass, the octave from 120Hz to 240Hz where much of an orchestra's foundation and acoustic power resides. This is the octave that box woofers have a hard time coping with, basically managing to sound boxy through this range. In contrast, the Augie managed to shine here, elucidating instrumental fundamentals with consummate clarity and 3D realism. The Augie's performance was so open-baffle friendly that I decided to use it as a foundation for several full range drivers. The OB2 finds the Augie mated with the fantastic Feastrex D5nf. Future projects will feature the Lowther DX55 and C55, as well as the new Jordan JXr 6HD module.” You may read the full review here. http://www.enjoythemusic.com/magazine/equipment/0107/diy_loudspeaker_project.htm Specifications: • 15" low frequency augmentation driver • Ideal for bass augmentation in open baffle and infinite baffle configurations • Heavy cast basket • Kevlar Reinforced Paper Cone Body w/mass plug • Long excursion poly/cotton cloth surround • Large copper shorting ring on the vented core • Poly/cotton linear flat spider • Knurled binding posts • 2.5" voice coil • Power handling: 225 watts RMS. • Impedance: 8 Ohms • SPL: 88.7 dB 1w/1m • Le: 0.81 • Re: 5.69 Ohms • Qt: 0.92 • Vas: 250.3 liters • Xmax: 7.15 mm • Fs: 27.0 Hz • Magnet weight: 67ounces • Cut out 13.875" • OD 15.25"
