The Swiss company PSI Audio released the\u00a0A125-M<\/a>\u00a0and\u00a0A225-M<\/a>\u00a0subwoofers\u00a0, in which they especially noted musicality and fidelity.\u00a0Both models have the same sound character to make it easier to scale the system.<\/p>\n

<\/figure>\n

New items are built on the basis of 8-inch drivers.\u00a0The A125-M has one such speaker, while the A225-M has two.\u00a0Accordingly, the dimensions of the cases differ, which can have a red, black or white coating.\u00a0Both cases are complemented by slotted bass reflexes, and the speakers are protected by convex metal grills.<\/p>\n

Both subwoofers were equipped with class G amplifiers. The 125 model has a capacity of 150, and the 225 has 200 watts.\u00a0Accordingly, PSI Audio Sub A225-M delivers 111 dB SPL with a lower frequency limit of 24 Hz.\u00a0For the single-driver A125-M, these figures were 106 dB and 28 Hz, respectively.<\/p>\n

<\/figure>\n

Both new items accept the input signal on a pair of balanced XLR connectors, the same switching is left for the output signal – this will allow using several synchronously operating subwoofers.\u00a0Signal delays in this case are minimal – PSI Audio products are 100% analog.<\/p>\n

In the UK, PSI Audio A125-M and A225-M subwoofers cost \u00a3 1,800 and \u00a3 2,550 respectively.<\/p>\n
