Paradigm

Reference Seismic 10 Subwoofer

Here's a very solid subwoofer that sounds great - loud and deep with excellent articulation.

Here's some info on it:

The result of an intensive four-year research and development program, Seismic™ subwoofers are radical new designs that showcase groundbreaking patented and proprietary technology that dramatically redefines the concept of high-end performance in subwoofers of this size. Breathtaking, articulate deep bass with incredible detail, definition and massive output … all contained in an implausibly compact, elegant and refined design.

High-Excursion Bass Driver
Designed and manufactured by Paradigm, these highly advanced high-excursion drivers with low-mass, high-stiffness cones are precision-engineered for extremely high power and ultra-low levels of distortion. The tremendous peak-to-peak cone excursion (over two inches in our Seismic™12) produces incredibly deep bass response with equally incredible speed and power.

• High-Pressure Die-Cast Aluminum Chassis: Controls flexing and ringing, and since aluminum is non-magnetic, stray magnetic losses are eliminated.

• AVS™ Airflow Ventilation Cooling System and Huge Heatsink Fins: Provide forced air cooling during extended cone excursion and convection cooling at all other times.

• Mineral-Filled Co-Polymer Polypropylene Cones with RCR™ Resonance Control Ribs: Both sides of the cone are ribbed, providing superior stiffness with low mass and excellent internal damping for tremendous freedom from unwanted resonances and distortion.

• Dual Spiders and Dual Ultra-Long-Travel Suspensions: One progressive and one linear, promote greater cone excursion while maintaining exacting control over cone movement.

• Dual Balanced-Plane High-Velocity Passive Radiators: Provide extended bass response with very low distortion. Solid, stable enclosures, unhampered by vibrations or resonances, contribute to the clean and articulate bass performance.

• Oversize 4+4-Layer High-Temperature Aluminum-Wire Voice Coil: Wound on a high-temperature Apical™ former, with advanced high- temperature coating and twin-layer bifilar configuration for greater stability and support during extended cone excursion.

• Proprietary Voice Coil Wire Guide: Allows large-gauge wire connection directly to the voice coil for unrestricted cone movement while eliminating the possibility of “cone slapping” of lead-in wires in this high-excursion application. Unique rigid wire guide cap stiffens the cone/voice coil interface.

• Massive Computer-Optimized Magnet Structures with Focused Field Geometry: 13 kg (29 lb) magnet structure on the Seismic™ 12 and 8.5 kg (19 lb) on the Seismic™ 10 generate an enormous magnetic force field while minimizing inductance distortion.

• Massive Vented Die-Cast Aluminum Center Heatsink: Provides internal forced-air cooling to drive heat away from the high-velocity low-turbulence pole piece, thereby increasing power handling and reducing distortion.

Seismic™ Ultra-Class-D™ Amplifier

• Super-Efficient Switching Amplifier: Over 90% efficiency, provides output of 1200 watts RMS, 4500 watts Peak.

• Novel Adaptive PWM Power Processor: Minimizes distortion and optimizes efficiency. Conventional Class-D designs have very low power supply rejection. Our Ultra-Class-D™ design inherently rejects power supply variations.

• No Power Transformer: The output stage is Direct-Connected™ to the power line to provide maximum power.

• Opto-Coupled Inputs: Offer better isolation and lower noise.

• Advanced Output Stage: Increases switching speed and efficiency. Unlike conventional Class-D designs, which use the slow built-in diodes of the output MOSFETs, our Ultra-Class-D™ design steers circulating currents to ultra-fast diodes (ten times faster).

• Proprietary Voice Coil Temperature Sensor: Should the voice coil overheat, the amplifier output is reduced until the voice coil cools down.

• Amplifier Temperature Sensor: Maintains safe operating temperatures even under extreme conditions.

• Short Circuit Protection: Reacts within 10µs.

Input Facilities

• Low-Level Input – RCA:
Allows connection from the RCA (S/E) Sub/LFE-Output of your Preamplifier/Processor, A/V receiver or other suitable low-level source. If connecting to a Stereo Preamplifier a Paradigm® X-30 subwoofer control unit is required. (See your Dealer for more information.)

• Low-Level Input – Balanced XLR:
Allows connection from the Balanced XLR Sub/LFE Output of your Preamplifier/Processor or other suitable low-level source. This input provides the lowest noise and distortion possible and is particularly important for long cable runs where noise and distortion could degrade performance.

Control Facilities

• Patented Auto On/Off:
Eliminates the need for a manually operated power switch. Turns the subwoofer on whenever there is an input signal. If no signal is sensed after a period it turns off.

• Trigger On/Off:
Allows the subwoofer’s power on/off to be controlled by components that have trigger outputs (Preamp/Processor or A/V Receiver, etc.)

• Subwoofer Level Control:
Balances the subwoofer level with that of the other speakers in your system.

• Subwoofer Cut-Off:
Controls the subwoofer’s upper-frequency cut-off. This can be set to match the low-frequency roll-off characteristics of your system’s speakers.

• Phase Alignment:
Accurately synchronizes your subwoofer and front speakers through their bass frequency overlap region.

• Bass Contour:
Adjusts the contour of bass from flat (0.0 dB), the most accurate for music, or up to +6.0 dB at 60 Hz for more bass impact with movies to best suit your personal listening preferences.

New this unit sold for $1495.  This consignment unit is on sale for just $750.
