SEAS Prestige ER15RLY - H1455 5.5" Reed Paper Cone Woofer

The SEAS Prestige ER15RLY - H1455-08 is a 5.5-inch reed paper cone woofer designed to deliver clean, controlled bass and midrange performance in compact speaker systems. As part of the renowned SEAS Prestige series, this driver combines traditional materials with modern engineering to produce a natural, uncoloured sound that audiophiles appreciate.

This woofer is ideally suited for use in two-way bookshelf speakers, small floor-standing designs, or as a dedicated mid-bass driver in multi-way systems. Its lightweight reed paper cone ensures fast transient response, making it particularly effective for reproducing vocals, acoustic instruments, and rhythmic bass lines with precision and clarity. The driver's moderate sensitivity of 87.5 dB and a total Q factor of 0.32 allow for flexible enclosure designs, including sealed and ported cabinets.

Technically, the ER15RLY features a 5.6 ohm DC resistance and a voice coil inductance of 0.73 mH, contributing to its controlled electrical behaviour. The mechanical Q (Qms) is 1.55, while the electromagnetic Q (Qes) is 0.41, resulting in a well-damped overall Qts of 0.32. With a maximum linear excursion of 5 mm, this woofer can handle moderate power levels while maintaining low distortion. The mounting cut-out diameter is 112 mm, with a screw circle of 136.4 mm and six fixing holes, ensuring straightforward installation into baffles up to 146 mm in overall diameter and 71.6 mm in depth.

In summary, the SEAS Prestige ER15RLY offers a refined balance of natural tonality and technical precision, making it an excellent choice for discerning builders seeking high-quality bass and midrange reproduction in compact loudspeaker projects.
