SB Audience OB3 Open Baffle 3-Way with 15" Woofer - PAIR
Designed by Scott Hinson ~ thank you!
Madisound is pleased to offer an easy to build and straight forward open baffle 3-way kit utilizing the new SB Audience line of drivers.
With the introduction of the Bianco-150B350 15" open baffle woofer, it made perfect sense to work it into a passive design geared towards DIY speaker building enthusiasts. The Nero-6MRN150D 6" midrange is an exciting driver, straddling that line between home hi-fi and pro-sound. With an extremely powerful neo magnet, advanced motor design, and high quality material build, the resulting driver stands alone from the crowd. Rounding out the top end is the Bianco 44CD-PK PEEK diaphragm tweeter mounted in the H250 horn, offering both a smooth response and markedly low distortion.
Full documentation and listening notes on this design can be found here.
Each crossover is professionally assembled by Madisound on our silver tinned inlaid OFC copper circuit boards.
The series tweeter circuit utilizes ClarityCap CSA capacitors and doubled up Mundorf Mresist MOX 10W resistors. The series midrange circuit comes with Solen Fastcap caps, Sidewinder air core 16awg coils, and doubled up Mundorf Mresist MOX 10W resistors. The woofer section uses a Sledgehammer steel laminate 15awg coil for the large mH value along with a Sidewinder air core 16awg coil for the smaller one.
Crossovers include hookup instructions. Available for separate purchase from the drop down menu.
