Subwoofer JL Audio 10W1v3-4

The W1v3 series subwoofers share many features with JL Audio's premium subwoofers, including the patented VRC™, Elevated Frame-Cooling and Floating Cone Attach Method™ technologies. As with JL Audio's flagship subwoofers, the development of these bass drivers was driven by the company's proprietary DMA modeling system to deliver excellent dynamic stability and low distortion within the intended power range. The mica-filled polypropylene cone is finished with an aluminum dustcap bearing the JL Audio logo, giving the subwoofer a refined appearance. The JL Audio 10W1v3 is an excellent choice when space is very limited and amplifier power is not among the highest. It features a shallow mounting depth and a compact motor design, allowing it to comfortably fit into many spaces where a typical 10-inch subwoofer won't. With no vent opening, the rear of the motor assembly can be placed directly against the enclosure boundary. Excellent excursion capability and linearity enable the reproduction of sub-bass with enormous range and quality. JL Audio's proprietary technologies further enhance its performance and reliability. All these features combine to deliver output, sound quality, and reliability that would be hard to find even in products costing twice as much!

Main features

10" subwoofer with 300 W RMS power and a 4 Ω voice coil.
FCAM™ technology for improved excursion control and dynamic alignment of the voice coil.
Subwoofer motor optimized using the patented DMA system.
Patented Elevated Frame Cooling design for improved power handling.
The VRC® system improves the stiffness and stability of the connection between the cone, spider and voice coil.
Rigid mica-filled polypropylene cone.
Shallow mounting depth for convenient installation even in tight spaces.
Spiders, voice coils, terminals and leads are pre-assembled using a patented process.
Optional decorative grille for subwoofer protection (not included).

About JL Audio

JL Audio is an American consumer audio manufacturer specializing in home, vehicle and marine audio. The company is a leading pioneer in car audio and is best known for its high-end subwoofers. Founded in 1975, it is one of the oldest manufacturers in this field. Originally focused on home audio, they began working in the car audio segment in the late 1970s and early 1980s as that market rapidly grew. Over its rich history, JL Audio has produced many unique and patented subwoofers that had almost no competition at the time. The same holds true today. The manufacturer's subwoofers impress with their performance and top-tier sound quality, unique patents and excellent craftsmanship. In particular, the top W6 and W7 series have long been among the most interesting products on today's market. Also noteworthy are the revolutionary flat subwoofers of the TW1 and TW3 series as well as perfectly tuned subwoofer enclosures. You can expect the same quality from their amplifiers, and their top products for integrating with factory audio systems are also worth mentioning. With JL Audio products you can't go wrong — you can always rely on their high quality and uniqueness.

Subwoofer diameterThe diameter of the subwoofer is indicated on the screw holes. The overall outer diameter of the subwoofer is usually 1-2 cm wider, depending on the size category of the subwoofer. For a 30 cm subwoofer, the outer diameter incl. protective rubber 31.8 cm and in the 25 cm subwoofer it is 26.5 cm incl. protective rubbers.	250 mm (10\")
RMS powerThe RMS power of the subwoofer is the constant power of continuous use of the subwoofer. If the power is exceeded for a longer period of time, irreversible damage may occur, or to burn out the voice coil of the subwoofer.	300 W
Sensitivity (SPL 1W/1m)Subwoofer sensitivity or efficiency. The sensitivity of the subwoofer is given in decibels (dB) and, in simple terms, means that the higher the value, the lower the demands on the power of the amplifier. This is a de facto rating of how a subwoofer converts watts to sound. Sensitivity ratings are in noise level measured at 1 meter from the subwoofer using 1 W (watt of power) or using 2.83 volts at the source at 1 meter. A higher decibel level means the subwoofer is louder with less power. For every 3 dB increase in sensitivity, the subwoofer requires half the power to reproduce the same volume. For example, if an 88 dB subwoofer needs 300 watts to produce a certain volume, then a 91 dB subwoofer needs only 150 watts to reach the same efficiency.	84.2 dB
ImpedanceImpedance - measurement of electrical resistance. When buying a subwoofer, it is very important that everyone make sure that the impedance matches the amplifier that you are connecting to it. For subwoofers with a double voice coil, we recommend following the information in the advice center! Example: A 2 Ohm subwoofer cannot be connected to an amplifier that is only stable up to 4 Ohms. A 4 Ohm subwoofer can easily be used on an amplifier that is stable up to 2 Ohms. Connecting a 4 Ohm subwoofer to an amplifier that is stable up to 4 Ohms also without problems. The most common subwoofer impedance is 4 Ohm.	4 Ω
Subwoofer diaphragm materialThe specific material from which the subwoofer membrane is made.	Mica-filled polypropylene
Subwoofer mounting depthThe mounting depth of the subwoofer is measured from the bottom edge of the magnet to the bottom edge of the subwoofer's metal or cast basket.	117 mm
Recommended enclosure volumeThe closed enclosure is characterized by a simple construction. Closed enclosures are usually smaller than bass-reflex enclosures, and a special damping fleece is used for their damping. A closed baffle has the advantage of preventing an acoustic short between the front and back radiation of the subwoofer diaphragm. The disadvantage is that the closed enclosure raises the natural resonance frequency of the used subwoofer and thereby also increases the lower limit frequency. This is because the back side of the diaphragm is forced to compress and dilute the air inside the enclosure when the subwoofer is radiating in a closed enclosure. This adds to the inherent stiffness of the subwoofer's oscillation system the stiffness of the air in the closed enclosure. This causes an increase in the stiffness of the oscillating system and thus an increase in the resonant frequency of the entire system: subwoofer -> loudspeaker. The increase in resonant frequency for a given subwoofer is greater, the smaller the volume of air in the closed enclosure. The relatively small volume of air in the closed enclosure acts on the subwoofer as an acoustic spring when radiating the back side of the membrane into the enclosed enclosure. USE: Mainly for quality bass listening in the entire band with an emphasis on detail and accurate reproduction in the lower band. Pros and cons: + pure reproduction + small closets + easier tuning - low level of efficiency in deep bass - loudness only at the cost of enormous deflection of the membrane - a significant acoustic pressure cannot be expected	15.57 l
Recommended bass reflex speaker volumeA bass reflex enclosure is designed in the same way as a closed enclosure, but it also has a so-called bass reflex mouthpiece, or "bass reflex" or slot. Needle foam is used to dampen bass reflex enclosures. USE: The ideal use is in cases where the listener wants to achieve a high volume and a good sound pressure level. It is the best compromise between sound quality and performance and is also the most commonly used Pros and cons: + good efficiency in deep bass + a small deflection of the membrane is enough for a large volume - reproduction less accurate than with closed enclosures	25.5 l
Fs - resonant frequencyFs - is the lower resonant frequency. This parameter is the de facto free air resonant frequency of the subwoofer. Simply put, it is the point at which the weight of the subwoofer's moving parts equals the force of the subwoofer's suspension while it is in motion. If you've ever seen a piece of string start to hum uncontrollably in the wind, you've seen the effect of reaching a resonant frequency. The weight of the moving parts and the stiffness of the suspension (surround and spider) are key elements that affect the resonant frequency. As a general rule, a lower Fs indicates a subwoofer that would be better at reproducing low frequencies than a subwoofer with a higher Fs. However, this is not always the case, as other important parameters of the subwoofer also enter the resulting sound.	26.15 Hz
Xmax + -Xmax - the maximum deflection of the subwoofer diaphragm in one direction – it is not a sum, or an abbreviation for the maximum linear deflection. The subwoofer output becomes non-linear as the voice coil begins to leave the magnetic gap.	11 mm
MassSubwoofer weight in kilograms. The weight is usually given net, i.e. without packaging.	4.5 Kg
