Parts/types of speakers: the specific parts of speakers and the number of individual parts are important factors in determining the cost. For example, electrostatic technology is usually more expensive than standard electric (moving coil) designs. It is also worth noting that paired speakers (of similar quality) are often more expensive than a single loudspeaker.
Part material: material cost is also a factor in speaker price. The price difference between ideal materials and unsatisfactory "good enough" materials will vary from part to part.
Labor/process: many well-known speaker brands produce speakers in small batches, even one at a time. This enables their speakers to pay full attention to details and professional technology, to produce high-quality and consistent products. These manufacturing technologies cost much more time (and money) than cheap assembly line manufacturing.
Product testing: another part of the labor may be the intensive testing of high-end speakers of reputable companies before reaching customers. Of course, this requires time and energy, and more funds. Through thorough testing, it can be ensured that the loudspeaker can reach its full potential before being used outside the manufacturer for the first time.
R D: there is no doubt that high-end speaker companies are often industry leaders in the field of innovation. Buying from high-end manufacturers will help them continue to develop awesome high-quality speakers.
Advertising: whether you like it or not, advertising is usually an essential part of the business. Few speaker manufacturing companies do not spend money on advertising. And advertising must highlight its biggest features. For example, if it is not excellent in volume, it can be labeled as the loudest speaker.
Brand name/identification: there are thousands of different speaker models on the market today, from cheap consumer Bluetooth speakers to professional wire arrays, from accurate studio monitors to enthusiast floor speakers. They are also sold as single drives, complete units with enclosures, or even in pairs or larger kits.
