Priced Per Midbass Driver (Individually Priced)

Speaker Specifications

This is the manufacturer product line of speakers.
ZR (JL Audio)
Priced Per
Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair". If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.
Each Speaker
Speaker Size
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
Component Woofer
Tweeter Design
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.
Tweeter Size
Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.
Tweeter Composition
Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

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.
Mineral-Filled 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.
Santoprene Rubber
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.
225 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.
125 watts
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".
87 dB
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).
50 - 500 Hz
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
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

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.
Cutout Dimensions
Refers to the dimensions of the hole, measured in inches, required to contain the speaker.
Speaker Grilles
A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.
Number of Speakers
This is the number of speaker that is included in the package. Each purchase will result in receiving the number of speakers indicated here. Please note that some items will have multiple woofers in the same enclosure. For sets of component speakers, this number will refer to the number of sets of speakers (For example, 2 would indicate the purchase includes 2 woofers and 2 tweeters).

Please refer to the product image and description for further details about the speaker.

works great

August 19, 2013

I was looking to simply replace my stock sub in my '02 Tahoe. The shallow Pioneer would not fit so I had to send that speaker back. The new sub rocks. No extra amp. I did not know the stock sub came from the factory already built into a box. The JL dropped in with zero modification. Truly sounds 5 times better than the original. I was worried about the oHms not matching and RMS ratings. Worry not. If I turn it up I can shake a window if I want.

These drivers made a GREAT difference in my setup depending on what you listen to, they really bring out the missing midrange BASS that the 6.5" midrange drivers simply can't pick up. An absolute MUST for a (complete) front stage...

JL Audio ZR800-CW

August 16, 2012

I replaced the 6.5” stock woofers in my 2008 Mustang GT with these to match with the JL 5X7s in the upper door and in the back also a JL 10” sub. These speakers really filled a whole in my sound. I'm driving them with a Sound Ordinance 2X75W amp which does a great job. They perform as advertised and I highly recommend them for any system if you have room in the doors. The only issues they posed is they don't drop in with no modification as advertised, we had to file away some of the plastic framing to get them to fit. My System sounds PDG, it' clean, full of detail, nicely staged and full of nuance. I got a great deal on the price and delivery compare to what I would have had to pay everywhere else I priced the speakers.

Thanks again Sonic.

great speaker

May 3, 2012

I hooked these two bad boys up to a JL 300/4 bridge to 2 channel, and they sound pretty damn good. I would definitely recommend them.

Excellent Midbass driver. I'm running a 4 way active system, and use these for 80hz - 250hz.. They fill that range superbly. I wouldn't recommend this driver for anyone UNLESS they're running 4 way active, because these speakers are only happy within this small frequency range.

Las Vegas, NV

Strong transition driver.

June 12, 2009

I bought this midbass as a bridge between dual 12" subs and a 6.5" mid/hi set of components. These high pass as low as 50Hz while taking 175-watts RMS and will very like take more wattage with a high pass of 60Hz or 70Hz. This is not a midrange speaker. This is a very application specific driver that should be used in 4-way active systems to transition from a very strong bass section to clean midrange section. My results so far have been beyond my expectations. The only weakness this driver has (if you can call it that) is that it isn't much good above 500Hz, so make sure you set your lowpass at 500Hz or less.

I have rated this driver according to fair criteria.

Overall = 4 (This is still the best driver in it's class for what it is used for.)

Value = 3 (It should cost less for what it does, it's not a full range driver, nor would it be considered a top subwoofer.)

Look/design = 5 (This midbass has a nice grill and look to it, and should blend in most installs aesthectically.)

Durability = 5 (This midbass can take a beating, is made of water resistant and wear resistant materials and will likely outlast 2 or 3 cars easily in it's lifetime.)

Features = 3 (I will use this for "versatility". This is a very specific and limited application driver to be used as a midbass. It's not good for much else.)

Ease of use = 2 (This driver will require professional installation or modification to most doors in order to fit properly. This midbass should be only purchase for a very specific project where it's intended use is well understood.)
