SPH-170

Monacor SPH-170 Bass / Mid speaker

The Monacor SPH-170 is a 7.25 inch (185mm) midwoofer featuring a carbon damped polypropylene cone, an inverse soft butyl rubber surround, a powerful 100mm ferrite magnet system and a rigid diecast aluminium basket.

Drive units that feature a smaller diameter voice coil, a plastic cone & an inverse surround (such as the original Spendor BC1 bass unit) often offer a linear bandwidth with a very sweet midrange performance and that is indeed the case with the SPH-170. A good choice for BBC inspired 2 way stand mount designs.

  • Carbonised polypropylene cone
