## Abstract

Systems and methods for selecting crossover frequencies for 2.1 speaker systems integrated into electronic displays are described. In an embodiment, an electronic display may include: a left speaker coupled to a left side of an enclosure, a right speaker coupled to a right side of the enclosure, and a subwoofer coupled to the left or right side of the enclosure. In another embodiment, a method may include: determining a position of an asymmetric subwoofer integrated into a display, and selecting a crossover frequency between the asymmetric subwoofer and a set of stereo speakers integrated into the display based, at least in part, upon the position.

## Claims

### Claim 1

An electronic display coupled to an IHS (Information Handling System), comprising:
a left speaker coupled to a left side of an enclosure;
a right speaker coupled to a right side of the enclosure; and
a subwoofer coupled to the left or right side of the enclosure;
wherein the left and right speakers are configured to reproduce components of an audio signal having frequencies above a crossover frequency, and wherein the subwoofer is configured to reproduce components of the audio signal having frequencies below the crossover frequency; and
wherein the crossover frequency is selected by the IHS based, at least in part, upon a position of the subwoofer relative to at least a portion of the enclosure.

### Claim 2 (depends on 1)

The electronic display of claim 1, wherein the portion of the enclosure is a horizontal center axis of the enclosure.

### Claim 3 (depends on 2)

The electronic display of claim 2, wherein the crossover frequency is 200 Hz.

### Claim 4 (depends on 2)

The electronic display of claim 2, wherein the crossover frequency is increased in response to the subwoofer being positioned farther from the horizontal center axis and decreased in response to the subwoofer being positioned closer to the horizontal center axis.

### Claim 5 (depends on 2)

The electronic display of claim 2, wherein the crossover frequency is selected, at least in part, to produce a balanced stereo output to a user.

### Claim 6 (depends on 5)

The electronic display of claim 5, wherein the crossover frequency is selected by the user.

### Claim 7 (depends on 2)

The electronic display of claim 2, wherein the crossover frequency is selected, at least in part, to produce an omni-directional output from the subwoofer as perceivable by a human user.

### Claim 8 (depends on 1)

The electronic display of claim 1, wherein the crossover frequency is selected, at least in part, based upon an application executed by the IHS coupled to the electronic display.

### Claim 9 (depends on 1)

The electronic display of claim 1, wherein the crossover frequency is selected, at least in part, based upon context information collected by the IHS coupled to the electronic display.

### Claim 10 (depends on 9)

The electronic display of claim 9, wherein the context information comprises a presence or absence of a user.

### Claim 11 (depends on 9)

The electronic display of claim 9, wherein the context information comprises a proximity of a user with respect to at least one of the IHS or the electronic display.

### Claim 12 (depends on 11)

The electronic display of claim 11, wherein the crossover frequency is increased in response to the user being farther from the at least one of the IHS or the electronic display and decreased in response to the user being closer to the at least one of the IHS or the electronic display.

### Claim 13

An Information Handling System (IHS), comprising:
an enclosure;
a left speaker coupled to a left side of the enclosure, a right speaker coupled to a right side of the enclosure, and a subwoofer coupled to the left or right side of the enclosure, wherein the left and right speakers are configured to receive audio components consisting of frequencies above a crossover frequency and the subwoofer is configured to receive audio components consisting of frequencies below the crossover frequency;
a processor coupled to the enclosure; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to select the crossover frequency based, at least in part, upon a position of the subwoofer relative to at least a portion of the enclosure.

### Claim 14 (depends on 13)

The memory storage device of claim 13, wherein the program instructions, upon execution, further cause the IHS to select the crossover frequency further based, at least in part, upon an application executed by the IHS.

### Claim 15 (depends on 13)

The memory storage device of claim 13, wherein the program instructions, upon execution, further cause the IHS to select the crossover frequency further based, at least in part, upon context information.

### Claim 16 (depends on 15)

The memory storage device of claim 15, wherein the context information comprises at least one of: a presence of a user, or a proximity of a user.

### Claim 17

A method, comprising:
determining a position of an asymmetric subwoofer integrated into a display relative to at least a portion of the display, wherein the display is integrated in or coupled to an IHS (Information Handling System); and
selecting, by the IHS, a crossover frequency between the asymmetric subwoofer and a set of stereo speakers integrated into the display based, at least in part, upon the position of the asymmetric subwoofer.

### Claim 18 (depends on 17)

The method of claim 17, wherein the selected crossover frequency produces an omni-directional output from the asymmetric subwoofer with respect to a human user.

### Claim 19 (depends on 17)

The method of claim 17, wherein the portion of the display is a center of the display, and wherein the selected crossover frequency has a first value in response to the asymmetric subwoofer being positioned at a first distance from the center of the display, and a second value in response to the asymmetric subwoofer being positioned at a second distance from the center of the display.
