The Logitech X-240 is a discontinued 2.1-channel PC multimedia speaker system launched in 2007. It consists of two slim satellite speakers, a powered down-firing subwoofer, and a wired control pod with an integrated stow-away cradle for portable music players such as iPods, Zunes, phones, and PDAs. Logitech announced it with a U.S. MSRP of $49.99, positioning it as a budget desktop speaker upgrade. (news.logitech.com)
The most reliable specifications are:
| Parameter | Logitech X-240 specification |
|---|---|
| System type | 2.1 PC speaker system |
| Total RMS power | 25 W RMS |
| Satellite power | 5 W RMS × 2 |
| Subwoofer power | 15 W RMS |
| Frequency response | 40 Hz – 20 kHz |
| Signal-to-noise ratio | >96 dB |
| Satellite drivers | 2-inch high-excursion driver per satellite |
| Subwoofer driver | 4-inch long-throw woofer |
| Subwoofer type | Ported, down-firing |
| Inputs | 3.5 mm stereo input; additional 3.5 mm input on control pod |
| Headphone output | Yes, on control pod |
| Controls | Power and master volume on wired pod |
| Special feature | Stow-away device cradle for portable music players |
| Original warranty | 2 years, typical retail listing |
The correct power figure is 25 W RMS, not 18 W RMS. Some secondary listings may mention 50 W, but that should be interpreted as a peak/marketing figure rather than continuous RMS output. Retail and review specifications consistently list 25 W RMS: 15 W subwoofer + 5 W per satellite. (newegg.com)
The X-240 was designed primarily for near-field desktop listening, not for high-fidelity room audio. Its target user was someone replacing weak built-in PC or monitor speakers with an inexpensive 2.1 system for:
Its distinctive feature is the wired control center. Logitech described it as both an audio control pod and a cradle for an iPod, MP3 player, PDA, or phone. The cradle stores flush when not in use, and the system included trays for devices such as iPod and Microsoft Zune. (news.logitech.com)
A technical clarification is important: the cradle is not a modern digital dock. It does not provide USB audio, Bluetooth, Lightning, USB-C, or digital control. It is essentially a mechanical holder plus analog 3.5 mm audio connection, with charging/syncing possible only through the user’s own cable routed through the cradle. (newegg.com)
The X-240 uses a conventional low-cost active 2.1 architecture:
The published frequency response is 40 Hz – 20 kHz, but this should be read as a broad consumer audio specification rather than a strict hi-fi tolerance band. Techgage noted that the 40 Hz low-frequency claim appeared optimistic in listening tests, although the subwoofer did produce useful output down to roughly the mid-40 Hz region before rolling off sharply. (techgage.com)
The system’s 15 W subwoofer and 4-inch driver are adequate for desktop bass enhancement, but the design cannot reproduce true deep sub-bass with authority. In practice, the strongest bass region is approximately 60–100 Hz, which gives punch and warmth but not accurate low-frequency extension. (techgage.com)
| Section | Driver configuration | Engineering implication |
|---|---|---|
| Satellites | One 2-inch full-range driver per side | Compact and inexpensive, but limited high-frequency refinement and midrange detail |
| Subwoofer | One 4-inch long-throw woofer | Good desktop bass for the price, but limited deep bass and output headroom |
The use of single-driver satellites means there is no separate tweeter. This simplifies the system and reduces cost, but it also limits treble detail, dispersion, and clean reproduction at higher levels. Techgage found the satellites acceptable for the price but criticized their plastic enclosures for adding coloration to the midrange. (techgage.com)
Reviewers generally found the X-240 to be a good value for its original price category.
Strengths:
Wired described it as a reasonably good desktop-listening system for about $50 and highlighted the cradle, headphone jack, small footprint, and value for non-critical listeners. (wired.com)
Techgage awarded the system a 7/10, calling it affordable and decent for the price, while noting that it represented its price category well rather than competing with higher-end systems. (techgage.com)
The most common criticisms are exactly what an engineer would expect from a low-cost compact 2.1 system:
Wired’s review was mixed: it found vocals and acoustic material surprisingly good, but described rock as congested in the midrange, treble as sometimes tinny, and bass as not very clean or precise. (wired.com)
Techgage’s listening tests were more technical. It found useful subwoofer output to about 45 Hz, strongest clean output around 60–100 Hz, and a somewhat “thudding” bass character. It also noted that at very high levels the limiter/equalization behavior could become audible, although this was less of a problem during normal music playback. (techgage.com)
The X-240 is now a legacy/discontinued product. Logitech still has a support page for the X-240 2.1 Speaker System, listing model variants such as S-0285A, S-0285B, S-0285D, and S-0285E, but the support page indicates no current downloads, documents, spare parts, or FAQs for the product. (support.logi.com)
In current terms, the X-240 is best viewed as a used budget PC speaker system. Modern alternatives generally add features the X-240 lacks, such as:
If buying today, the X-240 only makes sense if it is inexpensive, tested working, and you specifically want a simple analog 2.1 system.
A 4-inch woofer in a small ported enclosure can produce convincing mid-bass, especially near a desk or wall where boundary reinforcement helps. However, real low bass requires moving substantially more air. Air displacement is roughly related to cone area and excursion:
\[ V_d = Sd \times X{max} \]
where:
A small 4-inch woofer simply cannot move the same air volume as a larger 6.5-inch, 8-inch, or 10-inch subwoofer. Therefore, the X-240 can sound punchy around 60–100 Hz but will not reproduce the lowest octave of music or movie effects with authority.
The satellites use small full-range drivers. This is economical and compact, but one driver must cover a large frequency span. That leads to compromises:
This is why the X-240 can sound good for casual listening but not as detailed as a proper two-way active speaker or bookshelf speaker system.
To get the best performance:
Check the following before purchase:
| Check | Why it matters |
|---|---|
| Both satellites play equally | Cable or amplifier channel faults are common with age |
| Subwoofer works without buzz/hum | Power supply capacitors may be aged |
| Volume pot is smooth | Oxidized potentiometers cause crackling/dropouts |
| Control pod works | Many functions depend on the pod and hardwired cabling |
| No severe rattling from subwoofer | Possible loose port, damaged driver, or cabinet issue |
| All cables intact | Hardwired cables are less convenient to replace |
Because the system is nearly two decades old, capacitor aging, cable fatigue, and noisy controls are realistic failure modes.
The Logitech X-240 is a 25 W RMS 2.1 desktop speaker system with 5 W per satellite, 15 W subwoofer, 40 Hz–20 kHz frequency response, >96 dB SNR, a 4-inch down-firing subwoofer, and 2-inch satellite drivers. Its standout feature is the wired control pod with stow-away portable-device cradle, auxiliary input, volume control, power button, and headphone jack. (newegg.com)
Reviews generally describe it as good value for casual desktop use, with decent volume and useful bass for the price, but also with limited bass precision, modest treble detail, lightweight construction, and non-hi-fi sound quality. It is worth considering only as a cheap used system in good condition; for serious music listening, a modern powered 2.0 bookshelf system or a higher-quality 2.1 setup would be a better choice.
