Know before you buy
These speakers are quite efficient with a 92 dB sensitivity rating, meaning they can be driven easily by a wide range of amplifiers, including lower-power models. You do not need a massive, high-wattage power plant to get them to perform at their best.
Yes, the StudioMonitor 65s feature two sets of binding posts, making them fully capable of bi-wiring. This allows you to run separate cables to the high and low-frequency sections of the crossover for potentially cleaner signal delivery.
These are substantial bookshelf monitors measuring 20 inches tall and 18 inches deep. Because of their size and the top-firing passive radiator, you should ensure your stands or shelves have enough clearance to allow the bass to disperse properly.
While they are technically bookshelf speakers, their 18-inch depth and 22-pound weight make them quite large for a standard computer desk. They are better suited for dedicated speaker stands in a listening room or a larger media console.
The D’Appolito configuration, which places the tweeter between the two midrange drivers, helps create a more focused and precise soundstage. This design helps minimize floor and ceiling reflections, resulting in clearer imaging and more accurate vocal reproduction.
The integrated top-firing passive radiator provides a surprising amount of bass extension for a bookshelf speaker. While they handle low frequencies well on their own, adding a subwoofer can still provide that extra bottom-end weight if you are using them in a larger room for home theater.
