DIY Bluetooth Speaker on DSP ADAU1701

The project turned out to have high sound quality due to the DSP processor.
Case dimensions 180x175x255
Weight 4.2 kg
Components:
1 20mm beech tree covered with Varathane oil dark walnut
2 Bluetooth module AIYIMA Qualcomm QCC5125
3 RDC2-0027v3 ADAU1701 + PCM5102A DAC
4 DC-DC for Amplifier from 12V to 30V
5 DC-DC for ADAU1701 from 12V to 5V
5 DC-DC B1212S-2W for Bluetooth module
6 Potentiometer 10kOm - 3pcs (Volume, bass, terble)
7 Speakers AIYIMA 3 inch 8om (87gHz, nominal power 25W, max 60W)
8 Speakers GHXAMP 1 inch 8om (20W)
9 Amplifier AIYIMA TPA3250
10 Type-C Micro USB 3S charger
11 Battery 18650 3000mAh - 9pcs (12V) + BMS Balanced 3S 60A
In the latest version of the improvements, I changed the voltage converter to a more powerful one and added another 3 pcs of 18650 batteries (Battery now 3S 12.6V 9000mAh)
Many sound improvements were applied:
1. Power-on delay
2. Adjust the volume, bass and treble frequencies.
3. Correction of the frequency response curve (Auto equalizer based on frequency response measurements with a microphone)
4. Tone compensation (by volume control level)
5. Separation filter for low-frequency and high-frequency speakers)

De cuantos watts es la bocina, excelente trabajo

[@DIYAcoustic]

Rated power: 35W
Maximum power: 60 W
Nominal impedance: 8 ohms
Frequency response range: 85Hz-5kHz
Resonant frequency: 85 Hz, new measurements I got a result of 87.5, the speakers are really very good and with good parameters.
