About the RM25XL

The Joseph Audio RM25XL is a high‑fidelity 2‑1/2‑way floorstanding loudspeaker using three drivers in a D’Appolito-style array and a bass‑reflex cabinet with a downward‑firing port. It employs two 7-inch aluminum cone woofers and a 1-inch fabric dome tweeter, sourced from SEAS in Norway and built to Joseph Audio’s specifications for wide bandwidth and low distortion. The crossover uses Joseph Audio’s parallel asymmetrical Infinite Slope topology, providing very steep filter slopes, in‑phase driver integration, low distortion, and wide dynamic range. Nominal impedance is 8 ohms with a minimum around 6 ohms, making the RM25XL an easy amplifier load that pairs well with a broad range of solid‑state and tube amplifiers. Typical sensitivity is in the high‑80s dB range (approximately 88 dB at 2.83 V/1 m), and in-room bass extension reaches into the low‑30 Hz region (approximately 32 Hz, –2 dB), yielding near full‑range performance from a relatively compact cabinet. Reviewers consistently praise the RM25XL for excellent imaging, broad and even dispersion, neutrality, and balanced tonality over a wide listening window, along with bass performance that is notably deep for its footprint.
