That is a good point to bring up. I need to explain that.
In LV12R, the power amplifier module is from Hypex. They don't have a warranty for us (as a customer). So if their module goes out, we need to replace another module out of our own pocket. But all of us face the same challenge -- with today's "globalization", the supply chain is becoming more and more difficult. A lot of times, the flawed component is from the up-up stream component maker that only cost $0.10 (such as a resistor, or other things). So the supplier will say, well you find one defective component, I will give this batch of resistors free. But that is not even enough to cover 0.1% of the final product cost. The most serious problem these days is the remarking of semiconductors (that is, lower grade non-brand name semiconductor transistors/ICs are remarked to higher grade brand name to sell at higher prices). Small guys like us need to watch constantly about quality control of components. There was an SSD manufacturer sent an SSD to review and it turns out the chips in that unit are all fake/re-marked. Fortunately my supplier and I understand each other and we use the same supplier in the past 10 years and we do pay a bit higher component price. But that is definitely worth it. But we cannot look my supplier's book to assess the risk they take from their supplier. We trust the buy components directly from Toshiba or other manufacturers (not just they say they do).
My point is there is a lot of behind the scene work that we take care. Trust me, any warranty work cost us money. As you know from this forum, some companies get into trouble because warranty burden (plus they price their product to low in order to get business). When a company price the product so low, you can almost be sure the price is based on low warranty overhead. If the company ties their warranty to their supplier, the supplier can simply walk away and it will leave the company holding the bag.
Several pages back, a question was asked about RTROSE's warranty work. The voice coils of all HP drivers and other 15" drivers are from Precision Econowind in Florida. Everytime we have failure; we collect statistics and work with suppliers. But even with that, we still expose to suppliers own problem if there is one. As we learn more, we put in more QA checks. We do our best.
Sorry I really cannot stop writing on this subject. I hate my florescent light bulb goes out far earlier than what the manufacturer states (I wonder why there is no law suit for that), I started looking at LED light. On ebay, there is an individual selling Philips LED lights at 70% of retail prices. I bought a few of them and they are genuine. But deep down I wonder where the source is from. Some 20 years ago, I bought a hard drive from a company and they told me they don't have inventory at that time because they just got robbed a couple of days ago. It is sad story. Those HD go into other sourced sold at cheaper price and whoever bought them are happy. But one day, they can start selling fake ones together with genuine ones for higher profit. For me this is becoming a serious problem. I know my head is still clear and I won't take the same kind of risk of LED light on my work -- amplifier and subs. But I certainly hope all of my suppliers keep the same standard even in today's competitive society.
