If you want outrageous amounts of bass, you gotta move some air
The Hamrammr Sub15 Series of dual voice coil subwoofers, from Hamrammr, are not for the faint of heart. Built using the latest in subwoofer technology, Hamrammr subwoofers are the pinnacle of low frequency driver design. An Hamrammr subwoofer tests the strength of your foundation with fast, articulate, gut-wrenching bass.
The versatility you need for mobile, home, or pro subwoofer excellence
Dual 2 ohm voice coils allow for stereo 2 ohm and mono 1 ohm wiring configurations when connecting to high current car audio and professional audio amplifiers to extract maximum power. For home audio applications, simply wire the voice coils in series for a benign 4 ohm load for greater amplifier compatibility.
Built to produce massive low frequency output and keep on doing it
To improve power handling, increase thermal management, and reduce power compression, Hamrammr designed the SUB-series with large black anodized formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils.
Over 1-1/2″ of travel (3/4″ Xmax) is kept completely linear through the use of dual spiders that also limit distortion and rocking modes. “Tall-boy” rubber surrounds with integrated gaskets maintain driver surface area during extreme excursion moments. Thick, one-piece Nomex honeycomb covered cones are covered with woven, heavy-duty glass fibers creating ultra-still cones that resist deformation.
Cabinet recommendations:
• Sealed 3.1 cubic ft. (net internal) with 3 lbs. of Acousta-Stuf polyfill, f3 of 35 Hz with a 0.707 Qtc alignment
• Vented 6.0 cubic ft. (net internal, not including driver or port volume) with 6 lbs. of Acousta-Stuf tuned to 18 Hz with two 4″ diameter by 26″ long flared ports for an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.
Note: All parameters derived with voice coils wired in series.
