Subwoofer Specifications

Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
10"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
1000 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
300 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Single
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
30 - 1000 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
90 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
6.9 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Polypropylene
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
5-5/8"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
9-1/16"

I bought the KFC-W2511 about 6 months ago. It is a really good stereo. I hooked it up with Sirius satellite equipment and it works great. Friends of mine think I paid at least $400 for it. Great deck with more features than I can use for under $200.

I have this single 10" kenwood in my s10 and it hits pretty hard. If you have a small truck that you want to hook up I recommend this with a 850watt amp. For the wiring on it I have the DHD NTX- Gold wiring kit. Overall a great value for high performance.

February 13, 2009

Got these boys hooked up to my Hifonics amp pushing 350rms power. These bad boys have never gave me any problems whatsoever. I would recommend if you want good base and sound quality get these subs and also a ported box because when you are driving around the neighborhood you will notice heads turning with these boys and the ported box together in harmony.

Awesome woofer upgrade

January 6, 2009

I installed this speaker in place of the stock Bose woofer in my 350z roadster. This sub is tough...I dropped my 3/8" air ratchet on the cone twice as I was tightening the 12 bolts to the metal plate that holds the woofer in place and it didn't even leave a ding! Yes, the entire ratchet with the air hose attached! Good thing that the cone is stainless steel coated. The sub is not even installed in a box! I just sealed the area behind the sub with a roll of a/c vent insulation and sealed the joints with silicone. This gives the sub about 1.2 cub/ft of sealed volume. I hooked it up to a 250W rms amp and the difference is AMAZING. I'm a metalhead and the drums and bass solos sound clearer and tighter at 80mph than my Polk DSW Pro500 at home. And best of all, Sonic has a great deal on these. WHAT A BARGAIN! Thanks Sonic!

July 12, 2007

I just bought this sub a few weeks ago and finally had a chance to install it. I am running a 1200W Sony Explod Amp to this single subwoofer with a rockford fosgate amp kit and this sub hits the bass real hard. It is enclosed in a bandpass ported box. I recommend this sub, and with an excellent price.
