Kaiamann, denne blir hard å svelge, men det er ikke mulig å høre forskjell på to fornuftige forsterkere. Skal forklare senere. Men du må stille de 100% likt mht effekt. og uansett så er fordelene med dedikerte kanaler , uten passive delefiltre og aktiv deling samt rom korreksjon verdt mye mer.

Multi-Channel Systems: With the availability of affordable, high-quality digital amplifier boards, multi-channel systems are becoming more accessible. Instead of sticking with the traditional two-speaker setup, people are exploring 5.1 or 7.1 surround sound systems for a more immersive experience. This trend is driven by the desire for enhanced home theater experiences and better spatial audio.
Active vs. Passive Crossovers: The shift towards active crossovers is indeed a significant development. Active crossovers can provide better control over the audio signals sent to each speaker, leading to improved sound quality and efficiency. This shift is partly due to the increasing affordability and compactness of digital amplifiers, which makes it practical for more users to adopt this technology.

Class AB Amplifiers:
Class AB amplifiers are designed to combine the best aspects of Class A and Class B amplifiers, aiming to improve efficiency while maintaining good sound quality.
Efficiency: Class AB amplifiers have an efficiency that typically ranges from 50% to 60%. This means that almost half of the consumed power is just generating heat.
Operation: Class AB amplifiers operate by combining the characteristics of both Class A and Class B amplifiers. They use two transistors for the positive and negative halves of the waveform, but each transistor conducts more than half of the time (slightly overlapping at the crossover point), which reduces crossover distortion found in pure Class B designs.
Sound Quality: Class AB amplifiers offer a good compromise between the linearity and low distortion of Class A and the higher efficiency of Class B. They are widely used in consumer and professional audio applications due to their balance of performance and efficiency
The bottom picture shows a complete amplifier system, with 2x150W RMS for midrange/tweeter and 2x300W RMS for midbass and subwoofer. They do not offer any kind of active filters and the combined weight is 28 kilos with a total footprint of 96 cm x 40 cm x 9 cm (about 40 liters
Modern Class D Amplifiers:
Modern Class D Amplifiers:
Efficiency: Modern Class D amplifiers achieve efficiencies of 90-92%, minimizing power loss and heat generation.
Sound Quality: High-end Class D amplifiers now offer sound quality that rivals traditional Class A and AB amplifiers, with very low levels of distortion.
Applications: Widely used in a variety of applications, from portable audio devices and home theater systems to professional audio equipment and automotive sound systems.
The top picture shows a amplifier system, with 2x50W RMS for midrange/tweeter and 2x300W RMS for midbass and subwoofer. It has built in DSP and active crossovers and weighs about 1.2 kilo with the two required switched powersupplies (middle picture). They have a total footprint of 25 cm x 9 cm x 15 cm (3 liters).

CLass D amplifiers:
One significant shift is the move towards multi-channel audio systems. The traditional two-speaker setup is now just one of many options. With the rise of affordable high-quality digital amplifier boards, it's become increasingly feasible for consumers to set up systems with multiple channels. These setups, such as 5.1 or 7.1 surround sound systems, provide a more immersive audio experience, which is particularly appealing for home theaters and gaming. The flexibility of using multiple channels allows for more sophisticated sound staging and a more enveloping listening experienc
