Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Optidrive (Lanzar)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
6000 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.
3000 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.
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.
1.2 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
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 - 300 Hz
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
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.
15.5 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
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
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.
Laminated Pulp Cone
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.
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Triple Stacked
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.
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.

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
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.5 cubic feet
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.8 cubic feet
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 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.
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.


Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
52 Hz
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 10.
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
0.65 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 10.

It's a pretty sick sub, I'm under powering it a lot but it's crazy how clear and loud it is. I'm afraid of it's true potential!!!

Very happy with these subs. as durable as they come and sound quality has improved with being broken in. the 2000w hifonics amp I bought overheats trying to keep two of these going and shuts down on hot days after 20-30min. nothing against the subs or the amp. Needed to set up a dual battery system and upgrade my alternator to a 250 amp setup. have two 900 cca optima yellow tops one right next to the amp all 0 guage now. still not enough amp. buying the lanzar opti 4000 after I finish my hotrods engine. can only afford one toy at a time.

economy bass

May 30, 2014

I am 33. A master automotive Technician on every level. A genius when it comes to math. And I know electrical theory very well. So heres my story. blew up my subs after 8 years. my system averaged 145db and cost me 1300$ to build. I am an audiophile. My system was super clean and you could hear every sound and instrument like it was next to you at any volume that made the system breathe. And I make my own custom boxes. I built my own amp btw used an old Infinity reference series 1357W RMS 2 channel amp as the chassis for my work. it pushed 800w+ RMS at 2 ohms when it was done per channel. I bought alpine type R 12" subs and blew em up 8 months later, then bought Orions not the HCCA (which do blow cones after prolonged use btw 70-80$ repair I think there over rated) but they were rated higher than my type R's. 3 months later in the graveyard. bought used rockford 12's blew em up in 3 weeks, bought 12" memphis subs again not competition and rated higher than my Type R's and they lasted less than 2 weeks. All my friends dubbed me the "Sub Murderer" So I said to myself "I'll show you you stinkin amp!" bought 2 of these wired em in. Blew my amp up in 3 hours of usage just breaking them in.
Overall: BEST BANG FOR YOUR BUCK!!!! not audiophile quality, dont get as low as others, but I can live with that. At 48hz I can lean back in my seat and look at my instrument cluster and cant read it when the bass hits. me and my buddy sat in my driveway for 30 minutes listening to little john, ying yang twins, YG, and drake. just to get a back massage...... it was nice :)_. I took a shot during turn it down for what (we were celebrating the new subs) and I vomited on myself because the bass made it go down the wrong tube! Do I really need to go on. Gave it 4 stars for 1 reason, 1.3 ohms of resistance sucks to wire properly and if you dont know what your doing it's a waste of money
Value: comparable to 600$ competition subs for 200$ need I say more
Look/Design: I dont care about looks but they do look impressive. Designed like a rock!!!!
Durability: huuuge magnet, thick cast case, heavy duty wires hard wired to cone, cone is bullet proof. Every part of this sub is built for power.
Features: subs don't have features. they perform or they dont. Theese Perform!
Ease of use: not user friendly. know your math, electrical theory, and how to wire subs or kiss your amp goodbye!
So 128db out of box not broken in babying them. 7 days in a row about 2 hours each use. I push subs early as to not create ridges in the cones. 10 hours to mate the cones then bump em to smooth em out. turned it up 141db before warm. 3 hour road test at near max volume amp died. Was so hot I had to give it 30 minutes before I could touch it with bare hands. got louder by at least 8db as they warmed up. (I have never heard subs make such a change in sound after being warmed up, takes a solid 10 minutes). still limited on funds I purchased a 30F PC and a hifonics 2000W class D monoblock to power them. wired it at 1.3 ohms and is still getting the amp too hot for my taste. I will be returning the amp for something over 3000 or buying a 2nd PC and amp and running 2kw to each sub.
180A alt wired for up to 200A 1000 CCA deep cell batt 1/0 guage all the way. lights still dim voltage still drops. brought friend to supermarket today on a test run. 100 feet from front door and in the middle of a crowded supermarket he could hear me clearly. I make disturbing the peace fun :)
Play Loud! Peace!

One Big Sub

January 12, 2013

I recently bought this sub, and its awesome except for the fact that its not rated at 3000rms, i have it hooked up to a Planet Audio Anarchy Series AC5000.1D and that amp at 1Ohm is 3500 rms. i had this sub wired to .6 ohms and the gain on the amp turned half way up and bass boost off. the sub was clipping bad and got extreamly hot too close for comfort. so i wired it in series to a 2.4 ohm load and that on my amp is about 2500 rms. It does a lot better but i still cant use the bass boost and my gain is now 3/4 of the way so i figure about 2000 rms is safe for this sub, other than that it is one heavy ass sub, 52lbs i have it in a box that i built for a 2004 ford taurus and is tuned to 32hz it hits extreamly hard and well worth the money for this beast just beware of the limitations. other nice features are a 10 gauge direct wiring, strong basket and great surround and overall build. also sonic did take a while to ship this too me it took about 2 weeks to get it
