Tutorial: Product Nomenclature

Letters, numbers, hyphens, slashes...the keys to JL Audio's naming convention

Raw Woofer Drivers

The best way to understand JL Audio's nomenclature is to take an example and dissect it:

EXAMPLE: 10W6v3-D4

 10 

Driver size in inches 

For fractional diameters, the fraction is dropped, so a 13 1/2" driver would start with a "13" followed by the driver type designation.

Driver type

W : Woofer
IB
: Infinite Baffle

6v3

Driver Class

Larger numbers typically mean higher performance levels and more power handling. Current classes are Xv2, 0v3, 1v2, 3v3, 6v3 and 7AE for subwoofers. When a "v" is present in the model number, the number following the "v" is the "version number" of the driver line. Example: the W6v2 is the second version of the W6 driver line. "AE" denotes Anniversary Edition.

-D4 

Driver impedance

If this last number is preceded by a "D" (as in 10W6v3-D4), the driver has dual voice coils, each with the impedance of the number given.

All IB4 (infinite-baffle) subwoofers were of the 8 ohm variety (essentially IB4-8), and all original W6's are of the dual-6 ohm variety (W6-D6), but the -8 for the IB4's and the -D6 for the W6's were a redundancy and thus were dropped.


Evolution® Coaxial and Component Systems and Raw Drivers

As with our raw drivers, understanding the naming convention for our Evolution® lines can be best understood by dissecting an example.

EXAMPLE: XR650-CSi

 XR 

Series

The first two letters of the model number indicate the series of the system and/or raw driver:

ZR : Reference
XR
: Premium
VR
: Better
TR
: Good

650

Diameter of Largest Driver

Designates the size of the largest driver in the system or the size of the raw driver:

050 : 0.5 inch
075 : 0.75 inch
100
: 1 inch
350 : 3.5 inch
400
: 4 inch
525
: 5.25 inch
570
: 5 x 7 inch
600
: 6 inch
650
: 6.5 inch
690
: 6 x 9 inch

NOTE: In the XR653-CS, the largest driver is 6.5" in diameter and the system uses 3 drivers. Denoting the number of drivers in the system is unique to XR653's model number.

CS 

Type of System or Component

CS : Component System
CX
: Coaxial System
TX
: 3-Way Coaxial
CW
: Component Woofer
CT
: Component Tweeter
CM
: Component Mid-Range
pxo
: Crossover
cthp
: High-Pass Filter

i

Series Independent Information

TR (coaxials and component sets):  The "i" designates that these systems have been engineered to provide enhanced "presence" in the mid-range section of their frequency response curve as well as an increase in broadband efficiency.

VR Coaxials:  The "i" designates that these systems have been engineered to provide enhanced "presence" in the mid-range section of their frequency response curve as well as an increase in broadband efficiency.

VR Component Sets:  The "i" designates that these systems have been engineered to provide enhanced "presence" in the mid-range section of their frequency response curve as well as an increase in broadband efficiency. Also, the crossover network of these component sets allows the user to adjust the level of the tweeter.

XR  (Coaxials and Component sets):   The "i" designates that these systems use JL Audio's "intelligent" crossover design.  This crossover design allows the user to adjust mid-range presence level, tweeter level and (on the component sets only) gives the system bi-amp/bi-wire capability.

ZR  Component Sets:   The "i" designates that these systems use JL Audio's "intelligent" crossover design.  This crossover design allows the user to adjust mid-range presence level, tweeter level and gives the system bi-amp/bi-wire capability.

 

C-Series Evolution® Coaxial and Component Systems and Raw Drivers

The addition of various C-Series Speakers to the Evolution® line brought about a change to the naming convention listed above.

EXAMPLE: C5-650x

C

Driver type 

C : Component

Series

The first number indicates the series of the system and/or raw driver:

5 : Premium
3 : Better (Convertible)
2 : Good

650

Diameter of Largest Driver

Designates the size of the largest driver in the system or the size of the raw driver:

075 : 0.75 inch
100
: 1 inch
350
: 3.5 inch

NOTE: In the C5-653, the largest driver is 6.5" in diameter, and the system uses 3 drivers. Denoting the number of drivers in the system is unique to C5-653's model number.

Type of System or Component

x : Coaxial System
cw

ct
: Component Tweeter
pxo

cthp
: High-Pass Filter

NOTE: In the C5-650, the lack of any designation beyond the Diameter of the Largest Driver identifies this model as a Component System.
