5INOF

5FR delivers a good balance of low-mid frequencies. Extended frequency response opens opportunity do design compact audio systems with sizable amounts of low frequencies, yet wit great clarity in mid to high frequency region. The optimized behavior of this driver in the mid-frequency region allows the audio engineers design simplified passive crossovers or DSP without the needs for large equalizations.
The magnetic structure was designed around large high-grade ferrite magnet. All steel parts are extensively coated to cope with the most demanding environments.
The cone paper pulp and surround were fully developed by REDCATT engineers and address all major break-up modes. The speaker has improved off-axes frequency response.
The newly designed steel basket with front and rear gaskets allow this mid-woofer to be mounted from the front and rear.

The 5FRX8-465A is a 5-inch ferrite full-range driver rated at 60 W AES (120 W continuous) into a nominal 8-ohm load. Sensitivity is 89.55 dB (2.83V/1m; 88.16 dB at 1W/1m), the highest maximum SPL in the 5-inch full-range class at 105.9 dB. The Qts of 0.69 places this driver at the boundary between the sealed-preferred and free-air operating domains, making free-air and open-baffle use the primary recommendation for broadest low-frequency extension. The carbon fiber reinforced paper cone with NBR rubber surround and Nomex spider - all developed in-house by REDCATT engineers - is optimized to manage cone breakup modes and maintain clean, low-coloration response into the midrange. All steel parts are extensively coated for environmental durability, and dual front/rear gaskets allow front or rear baffle mounting.

The driver is rated for approximately 60 W AES (120 W continuous) and is intended for use with amplification typical of column speaker systems and multi-way PA designs. A high-pass filter at the enclosure tuning frequency (55-75 Hz for vented; ~100 Hz for sealed) is recommended, with a typical crossover to a high-frequency driver at 1,000-1,500 Hz. The 1.32 kHz column array coherence limit (130.5 mm OD) requires a co-located tweeter at or below 1.3 kHz in vertical column array deployments. DSP-controlled crossover and excursion limiting are recommended at high drive levels.

The 5FRX8-465A is suited for hi-fi and studio desktop loudspeakers, bookshelf monitors, column speaker systems, and multi-way installed sound designs where high sensitivity, 60 W AES power handling, dual-gasket front/rear mounting, and extensively coated construction are required. Good to use with dome tweeters such as 25TNX4-386B, 251TNX4-384, or 33TNX8-410B, or with 1-inch compression drivers such as 101NCDX8-160 in compact 2-way column and satellite PA designs.
