CT Sounds BIO-6-5-COX 6.5" Coaxial Speakers vs CT Sounds Meso 6.5" 3-Way Component Speakers

The Meso 3-way component set is the better speaker, and it should be. It handles far more power, uses a fiberglass cone, aluminum basket and a separate 3.5-inch midrange, and it has 247 ratings against 39. The Bio coaxial is the simpler buy: it drops into the factory hole, runs off a stock head unit and needs no crossover or tweeter mounting. Owners of the Bio like the clarity but several say low bass is thin. If you will add an amp and want a real soundstage, step up to the Meso.

• Choose the Bio 6.5 coaxial if you want a drop-in factory replacement run by your existing head unit, with no amp, crossover or separate tweeter mounting.
• Choose the Meso 6.5 3-way component if you plan to add an amplifier and want separate midrange and tweeter drivers with a proper crossover for a fuller soundstage.
