Which chip is the best, in terms of sound quality, if I want to use it up to 15+15W? Thank you!

Have you looked into chip amp/gain clone style circuits like the Audio Sector ones?

Solid State Amplification  - 
 
Some years ago, I designed a protection circuit for the speaker output using a PIC microcontroller. The basic idea is that this circuit switches an output relay between the amplifier output and the loudspeaker. More info on:

http://www.djuke.nl/en/projects/1-power-amplifiers/22-pic-based-speaker-protection

To make it more compact, I made a redesign with SMD components, also providing some additional functionality. Features:
- Supports 2 channels
- Protection against DC, HF and overtemperature
- Delayed switch on and immediate switch off, based on AC from transformer secondary winding
- 2 feedback leds (power, protect)
- Accepts large supply voltage (12-60V)
- Relay voltage from positive rail supply (e.g. for 48V relay) can be used or internally generated 12V

I hope you like it, please let me know your comments and/or suggestions.

isn't it too complicated - to use MCU for speaker protection?

Look! This headphone amlifier (Solid State, Class A) is assembled of Kit manufactured in Russia.

Report about the shipping, assembling and testing is by the link below.

Kit for assembling is available to buy (developers - phsound.ru) and it's really cheap now because high currency course in Russia.

The amplifying board with room for 2 x 22 uF/400 V polyprop decoupling caps. The amplifying stage is going to be hardwired as circuit simplicity makes this easy. Tube teflon sockets have been bought as these are now available from Hong Kong at reasonable price. The quality of these teflon ...

Next to my vdh Colibri cartridge and vdh phono stage, this 6N6P w.o.t. line stage is the best thing that has entered my hifi system ever. Trying out the TRAM with my Audio Mirror monoblocks and later GlowMaster KT88 amplifiers has been a true revelation. I'm afraid to say it even beats my 300B ...

Hello!
I have two Pioneer 15W drivers, and wanted to build a big portable speaker with them... However, the THD and quality of TDA7297 left me disappointed... Which amplifier board would you suggest if I'd like to have a decent sound at low price (max. 7-8 USD)? Thanks

I found as alternative to the 7297 some PAM8610 (?) amplifier boards on Aliexpress, but for 2$ they seemed me a little TOO cheap...

Thanks!

Make no mistake 10 Watts is a lot of power. Most speakers will push about 92-105 db of sound pressure (dependent on loudspeaker efficiency) at just 1 Watt. But sound pressure is a logarithmic scale. So to get louder you need to supply a corresponding exponentially higher power level too. How much power you actually need is determined by a variety of factors. But for many normal situations 10 Watts is sufficient. The higher Watt rating on many systems is just headroom, to avoid the distorted upper range. The whole one o'clock volume setting rule with integrated amplifiers. Go past 1 o'clock and you enter the distortion zone of many units. That may only be 10 Watts on a 100 Watt system too. Because being audio level controls volume knobs are logarithmic themselves.

Hello! I'm not very expert here, and I have a question...
Would a higher number of drivers, covering the whole sound spectrum, instead of just 2 or 3 drivers (tweeters, woofers, midranges) make the sound better and more natural? Of course, every driver would just play the frequencies it is optimized for, using Fourier, and the drivers would partially overlap each other...

For instance (just theorical example) in this kind of setup:

1x 50-600Hz
1x 400-800Hz
1x 600-1000Hz
1x 800-1200Hz
1x 1000Hz- 5Khz
1x 1.5Khz - 10KHz
1x 5KHz - 20KHz
1x 10KHz - 20KHz

Thanks!

It's great theoretical stuff to think over, but there's a pretty good reason recording studios and mastering rooms don't use eight-drivers-a-side monitoring, and it's not just the cost. That said, it's neat brain gym to think thru the technicalities and ramifications of out-there speaker systems.

On the brink of the new year lets showcase my modular Preamplifier project:
- CS4398 stereo DAC with 2x optical and 2x coaxial inputs
- 6x analog stereo inputs
- 2x analog 5.1 inputs
- 5.1 channel volumecontrol pcb based on CS3318 with integrated headphone amplifier
- Outputbuffers with NE5532
- PreampController pcb is the heart of the preamp and connects rotary encoder, buttons, display, input selection, volume control, etc

And as a bonus, it has a Raspberry Pi with Volumio acting as a media player. With some nice interconnection features:
- Switch on the preamp and select the right input when a song is played on the media player
- Show the song title in the Preamp display

More detailed information:
http://www.djuke.nl/en/projects/10-pre-amplifiers/34-preamplifierv2

Complete measurements will come later, but to give you some idea, the monitor outputs are below 0.001% THD @ 1kHz, front outputs below 0.0015% THD @ 1kHz

My DIY
Do you want this for your studio?

Made by myself active speaker system - one way speaker with built in solid state amplifier.

Consists of:
- Box - theatral speaker, made in USSR at 60th, Russian Klangfilm
- Speaker - famous Russian speaker 4A-28. Very loved by audio geeks. Russian klangfilm. Made at 70th.
- Amplifier - ultralinear, solid state. Designed by myself, assembled at Nordic Sea (really, it was done when I worked at sea voyage as radio officer).

Has a nice vintage sound and VERY low noise. No any adjusting of sound - volume knob only.

So, does anybody want this for his home studio?  May be used, for example, for recording guitar with pedal effect. For sale.
