CORT CM30R

Overview: This is an Impulse Response (IR) capture of the speaker section of a Cort CM30R combo amplifier, upgraded with a 10" Jensen Falcon C10/40 FA speaker. Captured at Fuego azul estudio. Fun fact: to achieve maximum acoustic isolation and a completely dry room sound, the amp was placed inside a closet filled with clothes during the capture process! Signal Chain & Capture Process: To get the purest representation of the speaker and power amp section without coloration, the test sweep was routed directly into the FX Loop Return of the Cort CM30R, completely bypassing the amplifier's preamp stage. The speaker was mic'd with an industry-standard Shure SM57 positioned off-axis at a 45-degree angle, pointing directly at the speaker cone. The capture was recorded using a PreSonus AudioBox USB 96 interface at 24-bit / 48 kHz to ensure optimal resolution and clarity. Tone Qualities: The Jensen Falcon 10" brings a warm, full-bodied character with a very sweet top end. Because it was captured bypassing the preamp and mic'd at a 45-degree angle, this IR tames harsh high frequencies while keeping the bite, chime, and midrange definition intact. It is extremely pedal-friendly and responds beautifully to treble-forward tones. Best Use Cases & Suggested Combinations: Ideal for players looking for a tight, articulate 10" speaker sound. It works incredibly well for atmospheric genres that rely on heavy modulation, reverse delays, and reverbs—like post-rock, shoegaze, and dream pop—but it also has enough punch for soft punk and hardcore rhythm guitars. Pro-Tip: This IR pairs beautifully with clean, high-headroom amplifier simulations. My personal recommendation is to run it alongside a Fender Twin Reverb amp model (this is my go-to live setup using a HeadRush Flex Prime).
