Why We Developed LPT91219SD | From Market Demand to Product Evolution The LPT91219SD was not built from scratch—it was born from real user needs and deep market insight. As an upgraded version of our high-performance LPT91219, this model reflects Samesay's flexible OEM design approach and our ability to listen, adapt, and innovate.
1. Direct Client Feedback on Bass Performance Although the original LPT91219 (75W*2) already stood out as one of the market's most powerful portable Bluetooth speakers, some of our professional customers—particularly those focused on DJ setups and event audio—wanted even deeper, stronger bass performance. Their message was clear:"More power, same footprint."
2. Enhanced Digital Audio Demands Today's audio users—especially in the home theater, karaoke, and high-end event spaces—are demanding cleaner, more accurate sound. To meet this, we added Optical and Coaxial input support, allowing the speaker to be connected directly to TVs or digital sources with minimal signal loss.
3. Pro-Level Applications Need Pro-Level Sound By upgrading to 100W*2 output, the LPT91219SD delivers the performance needed for larger venues, public events, and serious audio professionals. It fills a niche where a big Bluetooth speaker is not enough—what's needed is a big, loud, high-fidelity system with custom features.
4. Customization as a Core Design Principle Unlike off-the-shelf models, the LPT91219SD was designed with OEM/ODM flexibility from the ground up. The client who commissioned it also wanted potential expansion modules like laser lighting, smoke effects, and visual enhancements—all of which we made technically feasible.
OEM/ODM Custom Options – Unlock Full Customization Beyond standard configuration, LPT91219SD supports deeper customization options for clients who need more:
Retail Packaging, Accessory Set, Plug Type by Market
Certifications (CE, FCC, RoHS, etc.)
OEM/ODM Customization Workflow for LPT91219SD At Samesay, we offer a full-cycle, flexible customization process tailored to premium, high-performance speakers like the LPT91219SD. This speaker is designed for serious sound applications—and our workflow ensures it's matched perfectly to your brand and market vision.
Understand Your Requirements We start by learning your brand goals, usage scenarios, and product expectations—whether you're upgrading from the base LPT91219 or targeting a new market with louder, bass-heavier sound and advanced features like Optical/Coaxial input or smoke effects.
Propose Tailored Configuration Based on your needs, we provide a detailed proposal including technical upgrades (100W x2 power, speaker tuning), external design options, branding layout, packaging style, and optional features such as laser lights, remote control, and multilingual prompts.
Build & Evaluate Prototype A fully functional sample is created, featuring the requested customizations. We run audio output tests, lighting/smoke demo (if included), and wireless mic integration. This stage ensures the final unit meets your expectations in both design and performance.
Optimize Based on Feedback You test the sample and share your thoughts. We fine-tune audio (EQ modes, DSP), lighting effects, housing finish, and user interface elements like LED display logic and startup sounds. Final specs are confirmed for mass production.
Prepare for Production Once approved, we confirm tooling, source upgraded components, and prepare the production schedule. Any unique parts (e.g. smoke module, optical decoder) are sourced in parallel to ensure timely delivery.
Begin Mass Production All units go through strict quality control: output power verification, bass performance checks, connectivity tests (Bluetooth/Optical/Coaxial), and full-feature validation including LED/smoke/light interaction. Optional 3rd-party inspection available.
Handle Logistics & Shipping We manage packaging, labeling, barcoding, and shipping—whether you choose FOB, CIF, or DDP terms. Accessories (mic, remote, plug type) are bundled as per your request, and shipping documents are prepared accordingly.
Offer Ongoing Support Our job doesn't end at delivery. We provide fast reordering, firmware support, spare parts, and roadmap consultation for future upgrades (e.g. LPT91219 Pro). Your long-term success is our top priority.
