Q: Should a brand develop an upgraded trolley speaker or add a new size after a model achieves stable sales?

A: From a product‑life‑cycle perspective, once a trolley speaker hits stable mature‑stage sales, adding new sizes only targets a narrow segment of consumers rather than opening up broad‑based market demand. In most cases, the extra return will not grow proportionally with your additional investment. Even though you can reuse part of the existing mould and electronic solution, new sizes still bring extra costs including partial mould modification, new certification, updated packaging, extra pallet‑occupied CBM volume, expanded inventory pressure and longer sample‑testing cycles. If the expected incremental orders only come from a small group of buyers, your added investment may generate limited revenue, lower gross‑margin performance and a longer pay‑back period. By contrast, launching a functional upgrade on your proven mature model usually delivers more proportional returns: it serves your whole existing customer base instead of only a tiny niche group, refreshes overall competitiveness and delays product decline. Brands should weigh the targeted‑group size, forecasted incremental sales volume and all hidden extra costs before deciding whether to add new sizes or release an upgraded version.
