Two ongoing audio builds, one portable Bluetooth speaker salvaged from old TV drivers, one home theater soundbar designed around enclosure theory and DSP. Both are works in progress.
Speaker & Soundbar Builds
Electronics & Audio Engineering
Build 01
Upcycled Bluetooth Speaker
Portable build · Recycled drivers · Portable battery system
Repurposing full-range drivers salvaged from a broken flatscreen television into a portable, high-fidelity Bluetooth speaker powered by an off-the-shelf battery pack. The drivers were pre-epoxied into the enclosures and kept as such to avoid damaging them. The frequency sweep below shows the raw response before any tuning.
Objectives
- Salvage and characterize full-range drivers from a broken television found on the side of the road.
- Integrate a Bluetooth receiver module and battery pack power supply.
- Design a sleek and stylish enclosure while maintaining control access and charging ports.
Frequency Response — Raw Drivers
Raw driver frequency sweep · Peak at 41 Hz · 44 dB-A overall
Build 02
Custom Home Theater Soundbar
Home theater build · Acoustic theory · DSP integration
High-fidelity soundbar designed from scratch and mounted above a projector setup. The enclosure was shaped around acoustic theory, with an eye toward DSP-based room correction to flatten the response. The spectrum capture below shows the current in-room measurement with a pronounced peak in the low-mids — EQ tuning is ongoing.
Objectives
- Achieve a flat frequency response from 80 Hz to 20 kHz.
- Integrate DSP for room correction.
- Fabricate an enclosure that fits custom mounting requirements.
