MTX RTP212 Review:   This is a brand new, never been opened, MTX dual 12 inch loaded sub box with a matching MTX 600 watt mono block amp which sells for $599.99. Two MTX 12 inch subs come loaded and pre-wired at 2 ohms in a heavy duty MTX trapezoid enclosure saving you $80 by not having to build your own box. These MTX subs feature a high temperature 1.5" 4 ohm voice coil so they will handle 1200 watts of power for the pair or 600 watts each and it also allows for maximum excursion. They have an ALDS Asymmetrical Linear Drive System with a flat progressive spider and extended pole piece for smooth, linear, piston like drive. Spider plateau venting makes sure the voice coils stay cool protecting your subwoofers. Included is a MTX 600 watt mono block amp which is perfectly matched to this sub box and features both high and low level inputs with a built in crossover and bass boost.

Polk Audio AA2120-A Review:   Put your car audio system on steroids. Two db124 12-inch subwoofers in a perfectly optimized enclosure.

   Ultra-stiff Metalized Polypropylene Dynamic Balance Cone for massive bass. Dish Cone design is supported by a Vented Cone Coupler, increasing axial rigidity "like Viagra for your subwoofer!"
   Marine Certified Polk/MOMO speakers are built tough to withstand the toughest environments so they are perfect for use in boats of all types
   Optimized for high performance in small sealed enclosures but versatile enough to pound hard even in bandpass and vented enclosures¾ Flat, deep bass with great extension as only Polk/MOMO can do it.
   Frequency response 23Hz to 200Hz
   Durable, airtight Rubber Surround for a long life of extended linear motion, optimized to achieve the longest throw possible for the cone: "Big cone, big throw!"


Polk Audio AA2124-B Review:   Polk/MOMO Subwoofers are like compact thunder machines. They have an ultra-stiff Dynamic Balance Cone. The "Dish Cone" design is mechanically supported by a unique Vented Cone Coupler. This Coupler looks like the outspread fingers of a hand holding up a basketball.This incredible Vented Cone Coupler is constructed of rigid injection-molded ABS. Its support increases the sub's axial rigidity, literally propping up the dish cone, distributing the motive force of the Voice Coil over a larger surface area of the cone. It's the same principle as if the Voice Coil were wearing snowshoes and the bottom of the cone was tundra. It's the same principle as if the dish cone was gobbling handfuls of Viagra just minutes before a hot date. The result of all this propping and rigidity and tundra is a vast reduction in distortion-producing cone break-up and resonance, for quick, clean, deep bass; Polk/MOMO-style bass!Polk/MOMO Championship Performance car audio speakers are engineered by Polk Audio with ultra high-tech materials for competition-level performance and durability. They're styled exclusively by MOMO, the world's preeminent designer of racing accessories, to look as good as they sound. And for motor sports enthusiasts the world over, a MOMO product is a charismatic symbol of the finest quality.When you consider your car an extension of your personality, Polk Audio/MOMO High Performance Car Audio is the perfect synthesis of technology and design.

JBL GTO1220 Review:   Kevlar-impregnated paper woofer cone has been chosen for its high strength-to-weight ratio, and is formed using a proprietary manufacturing process. Besides improving transient response, this cone material adds stiffness to relieve stress concentrations that may accumulate at the base of the cone under high-power and high-pressure applications. This is the same cone used in the flagship GTi series subwoofers.Nitrile-butylene-rubber one-piece surround and gasket provides an optimum blend of elasticity and internal damping, resistance to ultraviolet radiation, and durability despite extreme temperature and humidity variations. The large size of the roll was optimized to offer good long-throw linearity with the proper amount of control and stability at excursion limits.The frame on the GTO Series uses thick wall construction which offers maximum rigidity to support the motor structure, and its fully vented architecture provides maximum movement of air behind the cone and spider for maximum cooling. Maximum rear-window area is provided to minimize acoustic compression of the cone's motion at high excursion.

Panasonic CJ-SW3003U Review:   Wide Rubber Edge for Powerful, Accurate Bass, 4-Layer Voice Coil for High Power Handling, Large Dual Damper Suspension System, Screw Type Terminals. Wide Rubber Edge for Powerful, Accurate BassNow 1.5 times the size of the edge on our previous models, this wide rubber edge performs the essential task of linking the cone to the frame. Supple yet providing damping control, this wide edge is able to follow cone movement during large excursions, ensuring heart-pounding bass thats both powerful and accurate for even the most demanding bass tones.4-Layer Voice Coil for High Power HandlingLong-throw voice coils support linear movement of the diaphragm during reproduction of large amplitude signals. Heat-resistant wire is used in a 4-layer coil winding to assure high power handling. Aluminum bobbin construction provides excellent heat dispersion characteristics so that even at the maximum rated input of 1400W, there is still a margin of reliability. Large Dual Damper Suspension SystemSince extremely large input signals may may be more than a single damper can handle, every Panasonic subwoofer is equipped with large dual dampers. Regardless of installation conditions, this robust design maintains linear cone movement during large excursions, while applying suitable damping for a controlled yet powerful bass sound. Screw Type TerminalsDesigned to permit a secure connection of heavy-duty high-performance cables, these large terminals assure high signal transmission efficiency while resisting corrosion.Specifications Size: 12" Peak Input Power: 1400W Frequency Range: 18Hz - 3kHz (-10dB) Sensitivity (S.P.L., dB/W/m): 89 Nominal Impedance: 4 ohms Magnet Weight: 45 oz Mounting Depth: 5.492" Mounting Location: trunk Wide Rubber Edge Cone Material: High rigidity mica/polypropylene composite oven cone and center cap 4-layer Voice Coil Large Dual Dampers Diaphragm with Large Center Cap Screw-type Terminals (gold-plated) High Power Handling with minimum dist
