The 3500s are among the most sonically accurate sub drivers available. This accuracy comes from a low moving mass, ultra-high energy design that uses a powerful motor combined with a long gap/long coil topology found on the legendary 9500 and 9900 subwoofers. Like their big brothers, the 3500 Series subwoofers feature V-ROM surrounds, multi-layered spiders, 800-degree thermoset voice coils and cast aluminum frames. All of these features make the 3500 Series a brutally musical addition to the USA-built lineup.

The 3500 Series is equipped with the Evolution Subwoofer Package (ESP). ESP-equipped drivers feature a deeper frame than standard subwoofers and an exclusive surround and cone design. ESP subwoofers are truly built to maximize performance in their respective size class.

The 3500 Series comes standard with an oversized black composite drywall dust cap, red logo, and treated cellulose cone, but can be optioned with alternative composite dust caps, composite cones, powder coated frames, boost, and a variety of logo options to give your subwoofer a custom look and/or added performance for a specific application.
ESP Subwoofer Features:
  • Carbon Fiber Blend Cone (CFB) - CFB composition uses an effective carbon fiber-based cocktail to give you the highest strength-to-weight ratio in the industry.
  • Vario-Density Extended Range of Motion Surround (V-ROM) - Provides the ultimate in linear control at high excursion while enabling dynamic-sounding bass response. The control ribs are compressed to a lower density than the main surround body to provide a stepless control system. The harder you control it, the more control you get.
  • Tuned Spider System (TSS) - Each suspension is tuned for specific performance characteristics, e.g. High Definition, Power Handling, X-Stiff Control.
  • Super-Frame (SFrame) - Maximizes spider diameter, cone diameter, suspension deflection, thus working as a secondary shorting ring and providing additional heat dissipation for better heat flow from the coil.
  • SuperCharge option possible!
Features:
  • 38cm (15") subwoofer
  • Power handling (RMS) 1200 watts
  • Peak power handling (Peak) 4800 Watt
  • Impedance options: Double 2 Ohm or Double 4 Ohm
  • Patented ferrite magnet system
  • Lossless linear suspension
  • Ribbed foam surround
  • Magnetic protection cap incl. grid in front of pole core hole
  • Aluminum die cast basket

Data:

  • Playback range 10Hz - 500Hz
  • DC resistance (Re) 1.9Ohm
  • Resonant frequency (Fs) 38.36Hz
  • Mechanical quality (Qms) 7.53
  • Electrical quality (Qes) 0.67
  • Total quality (Qts) 0.62
  • Equivalent volume (Vas) 70.22 L
  • Xmax +-17,5mm
  • Magnet weight 350 Oz
  • Coil diameter 3" (76.2mm)

SuperCharge Option:

  • With the SuperCharge option, you'll hear even tighter and cleaner bass across the entire power bandwidth.
  • What exactly happens with SuperCharging? By adding a specially shaped neodymium shorting ring on a flush-cut pole piece, with the opposite polarity facing down, you redirect otherwise lost magnetic energy into the voice coil gap. This increases the usable motor power by 20-25%, allowing smaller, lighter motors to have the same drive energy as larger motors.
  • You can't run a SuperCharged sub at more power and the SPL doesn't increase, but you will hear cleaner output at higher levels. SuperCharged subwoofers use the power you give them more efficiently, but you still have the same heat dissipation and voice coil area. That means the power handling is the same as the standard model.
  • Info: The Supercharge subwoofers are made to order. The delivery time is 4-6 weeks in addition to the stated delivery time.
