dear coustomer: some product housing are the same, but the design and inside material are totally different.
the 12v 30w siren built magnet inside, and taking about magnet, there are three types: 8, 10, 12 type, the magnet determinate the siren's sound frequency and consumption greatly. Our sr-a76-30 adopt 12 type magnet, it takes advantages not only high db sound output, but also the sound can be boomed very far place ( the sound can transmit to long distance).by comparision, some company adopt circuit instead of magnet to lower cost, you are professional customer, please take the samples or the inside structurer to compare to make your decision.
