Our take on the Kicker 40CWD84

by John Pollard
Kicker

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Legendary bass, awesome price

If you're looking to add some boom to your car's sound system, Kicker's CompD line will get your car shaking without draining your wallet. These subs are the latest in the legendary Kicker Comp line that started in 1986, with a proven pedigree when it comes to delivering powerful bass.

The heavy steel basket cuts down on unwanted vibrations.

Kicker technology at work

Kicker's 40CWD84 8" subwoofer features a flex-resistant polypropylene cone for hard-hitting lows without distortion, while the ribbed foam surround promotes long excursion and helps to keep the cone on target. The sub's steel basket provides a reliable foundation for big bass, and its extensive venting ensures long-lasting performance that won't break down when the bass gets heavy.

Easy to add to nearly any setup

This sub handles up to 200 watts RMS to bring out the depth your music's been missing, and its dual 4-ohm voice coils make it easy to connect to a mono amplifier. This versatile sub works well in sealed or ported enclosures, and it's even suitable for free-air applications.

Highlights:

  • 8" subwoofer with dual 4-ohm voice coils
  • injection-molded polypropylene cone
  • ribbed foam surround
  • suitable for free-air use
  • power handling: 50-200 watts RMS (100 watts per coil)
  • peak power handling: 400 watts
  • frequency response: 30-500 Hz

Subwoofer Features
Enclosure Compatibility

Subwoofer Features

Dual Voice Coils: For increased system flexibility, the woofer has two 4Ω voice coils. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When wired in series, the woofer presents an 8Ω load.

Ribbed Surround: The optimized ribbed polyurethane helps eliminate flex and distortion.

Spiralead Tinsel Leads: The durable Spiralead tinsel leads are woven into the woofer's spider, for added strength and reliability.

Steel Basket with Vented Pole Piece: The steel basket's vented pole piece and Kicker's Quad Venting slots contribute to the woofers' efficient cooling and durability.

Speaker Terminals: Each speaker terminal has two 0.25" push-on terminals (crimp-on quick slides included).

Enclosure Compatibility

Enclosure Versatility: The Kicker Comp subwoofer is versatile, performing well in vented or sealed enclosures, and in free-air applications.

Sealed Enclosures: A sealed enclosure design offers the smoothest response, with increased energy at the lowest frequencies (between 20 to 30 Hz).

  • Minimum enclosure volume: 0.5 ft³
  • Maximum enclosure volume: 1.2 ft³

Ported Enclosures: A ported (vented) enclosure design is typically more efficient than a sealed enclosure.

  • Minimum enclosure volume: 0.66 ft³ with a 1.5" x 8" slot port opening that is 18" deep
  • Maximum enclosure volume: 1.2 ft³ with a 1.5" x 8" slot port opening that is 12.25" deep

Infinite Baffle Mounting: The Kicker Comp subwoofers are also designed to be used as free-air drivers. The infinite baffle mounting method effectively utilizes the trunk of a sedan as the enclosure.

Kicker a good replacement for Lexus Mark Levinson sub

Written By DownieD, La Grange, NC on Tuesday, April 08, 2014
Crutchfield Customer Review (What's this?)
 
Very good replacement for the 04 Lexus 430 Mark Levinson rear deck free air subwoofer. Simply wire the dual voice coil in series to get a closer impedance match. Not quite as loud as Levinson subwoofer, but can't beat the value. Lexus wants some $400+ for the stock replacement which is crazy when you can install this product for less than 1/4 the cost. It's a no brainer.
Pros:
Great value, great sound.
Cons:
Have to modify slightly to get it to fit the existing Lexus installation bracket. Not too difficult, just takes a little planning.

Nice Subtle Subs

Written By QD, Downingtown, Pa on Friday, June 14, 2013
 
These are nice subs if you want some bass without taking up a lot of space. I custome fit these subs in the rear deck of my Volvo S60T. They are hooked up to a 2 channel Boston Acustics amp (80 watts per channel / low pass filter). These subs rock. Suprising bass for small subs. No box either. Just a pair of oversized baffels to help with rattle since I had to cut the opening to make it wide enough to fit the 8's. Very nice. I'm now a fan of Kicker and will outfit the rest of my car with their gear.
Pros:
Nice bass for the size. Came with install gear
Cons:
None that I've noticed.
