Rocky Mountain Audio Festival (RMAF) 2011
|Audeze will be attending the Rocky Mountain Audio Festival (RMAF) from Oct 14 -16th in Denver, CO. Come visit us at CanJam@RMAF and at the Atrium 4th Floor, Room 477. At this year's event, Audeze will once again be showcasing our latest audio products.|
We recently moved to a new vendor for our LCD2 cables. Because of this change, the LCD2 cables will look visually a little bit different compared to our existing cables. Internally, these new cables use the same material and the wiring diagram remains the same. This change in vendors has now afforded us the ability to offer a balanced cable as an accessory.
Additional Driver Information
Several customers have emailed us asking for more details regarding changes in our driver manufacturing. We want to be open and transparent with our customers on the changes we are implementing so below is some additional information outlining our manufacturing and thought processes.
Recent Purchase Upgrade
We have received a fair amount of inquiries about the LCD2 Rev 2 driver. Since some of you may have missed the new revision by a few days of purchase we thought it would be the right thing to offer those of who purchased the LCD2 in the month of June the opportunity to ship your headphones back to Audeze for a complimentary upgrade. At the time of the upgrade we will additionally offer those within the specified period of purchase the opportunity to upgrade to a leather headband for $50.
Driver Update and Leather Headband
Audeze LCD2 headphones were introduced in October of 2009. Even among planar magnetic headphones currently on the market (and those of the past), our drivers were quite different with our unique structure and design. The LCD2 has gone through several minor cosmetic changes, but the driver has remained unchanged thus far.
- LCD2 with the current headband - $945 (No price change -- comes with the new Rev2 driver)
- LCD2 with leather headband - $995 (leather headband, Rev2 driver standard)
- Separate leather headband accessory - $100 (comes with headband and blocks)
- Separate headband assembly (with yoke, pins etc) - $140
We have received a few emails about driver failures. We continue to stand behind our driver and will offer full warranty, repair or replacement for any headphone issue including this one. There is no co-relation between serial numbers on headphones and driver. The Driver assembly is done separately and the headband is done in a different facility ahead of time. These failures seem to occur after the final testing phase, a little while later. We have received some of the defective units back and we have done failure analysis on them. The defective units seem to be connected to a small batch of raw material. This issue is limited to a roll of the material lamination and we have added additional tests, QC processes etc to completely eliminate this issue.
Our manufacturing process includes several stages of testing and inspection of raw materials, components, subassemblies and final product. We have changed and revamped our production process and quality processes to do extended tests and quality control in order to catch potential problems like these that are not apparent initially.
Critical component of each transducer is diaphragm. We are now doing an additional 100% visual test on each diaphragm under microscope for uniformity of traces and have very high criteria for approval. Electrical tests are performed for circuit continuity and impedance matching. We have also added an extended very high power test to eliminate potentially bad circuits.
Normally assembled transducers are being tested for frequency response and distortion. Measurements are performed in IEC Baffle. At this stage we match transducer pairs for sensitivity and frequency response within +/-0.5dB.
For final testing we have added high power tests with sine tones with average SPL over 120dB.
Assembled headphones are being measured with Neumann KU 100 Artificial Head for Frequency Response and Distortion. Before Shipping we have now added a long burn in test on every headphone with Pink Noise at average level of 95 dB. We continue to stand behind our driver and will offer full warranty, repair and replacement for any headphone issue. We are quite confident these additional tests will ensure that these issues do not occur again. We have worked with our suppliers to completely eliminate this issue in future.
AVGuide on LCD-2
AVguide: “The sound: full-bodied, very revealing, and yet almost shockingly smooth. A true sonic “chameleon,” the LCD-2 instantly and effortlessly reveals even small differences between associated electronics”
