Klipsch ProMedia 2.1 Computer Speaker System Teardown

07 November 2008

Overview / Main Features

The Klipsch ProMedia 2.1 is a 3-piece (2.1) , powered satellite speaker system for use with PCs, but could also be used with PMPs, and gaming consoles.

Target Market

Mainstream consumers - PC users such as gamers or those using PC as home entertainment system looking for better quality audio, as well as those using their MP3 players / iPods as the core of their sound system. Klipsch has historically always courted the higher-end of the field in terms of consumers - though in this case they seem to be lending their name to a very mainstream product with no particular.

Released

No press release found from Klipsch, however, according to CNET's review, ProMedia 2.1 speakers have been on the market since 2002.

Pricing and Availability

Pricing - This system retails for $149.99 at the time of writing, however, the system was found for prices as low as the $134 USD (Nov 2008).

Availability - assumed to be worldwide, or at least in regions where the Klipsch brand name recognition is high (North America).

Volume Estimations

For the purposes of this teardown analysis, we have assumed an 'order of magnitude' lifetime production volume assumption of 1M units over a period of 3 to 4 years.

As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed, volumes increment by an order of magnitude. Minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis.

What Is Not Included in our Cost Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

Manufacturing Notes

OEM/ODM/EMS Relationships / Manufacturing

In the world of speaker cabinets and speaker systems such as this, there are many specialized manufacturers and ODM-type companies that also build their own designs for private labelers, primarily based in China. We do not know if this system was designed by the OEM (Klipsch) and simply outsourced as a completed design to such a manufacturer, however we are, for the purposes of this analysis, assuming that the system is completely outsourced to a 3rd party manufacturing the systems for the OEM.

Country of Origin / Volume Assumptions

This system was made in China (per product markings), as one would expect most such systems (which are primarily hand-assembled and feature primarily low tech components and assembly methods as well as disproportionate plastics content) to be made in China that compete with this system.

Country of origin assumptions related directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies (such as WLAN modules or Bluetooth modules), we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. "Auto inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pin-count of the device. This calculation is affected by country or region of origin as well.

Design for Manufacturing / Device Complexity

This system has a total of 559 components, of which 130 are mechanical components. The electronic components used in this system are primarily thru-hole technology (with a handful of SMT components on the underside of the main PCB - all passive components, though). Such PCBs are very similar to power supply assemblies. This system is very comparable in terms of quantifiable complexity, to the competing Logitech Z-2300 2.1 speaker system - both systems have roughly the same component counts and neither stands out as exceptional in terms of over or underdesign.

Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design. The cost of manufacturing is also, to some extent, decreased in this case because of assumed labor rate applied for China.

Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.

Design Notes

Here is a summary of the major components used in the Logitech Z-2300 Speaker System design (bearing in mind that the main cost drivers are in fact the speakers ad cabinets, and not, as is the case with other electronic devices, the integrated circuits and 'components' such as these that drive costs and the design).

Electronic Components

Amplifier

  • ST Microelectronics - TL074CN - Op Amp, Quad, Low Noise, JFET Inputs
  • There are 3 of these amplifiers located in 3 different sub-assemblies (Subwoofer Power Amplifier PCB, Interface/Distribution PCB, I/O & Control PCB). There is, in fact, no other integrated circuit content.
