Peerless NE123W-08, 4" Wide Band Woofer

Peerless NE123W-08, 4" Woofer/Full Range in 8 ohm

This 4 inch 8 ohm member of the NE family has leading-edge transducer technology packaged in a cutting edge, stylistic design. The woofers in this family feature an innovative cast aluminium basket design which minimizes acoustic reflections inside the driver, through large basket windows and sculpted basket spokes. The basket also is designed to act as a highly coupled heat sink to the Neodymium-Iron-Boron magnet (NdFeB) motor, so as to improve power handling capacity. The cone and dust cap are constructed of natural wood fiber material with proprietary coating formulas and processes, so as to yield high clarity products. The cone designs also utilize pentacone technology for improved frequency response. The voice coil bobbin is titanium, for improved performance. The FEA-designed motor features copper caps to minimize inductance and extend performance to high frequencies. Rounding out the design is a 4-way terminal block connector, for ease of electrical connection.

Suggested Boxes:

0.1 cubic foot sealed for a 3dB down of 145Hz

0.15 cubic foot ported with 1" diameter port by 3" long for 3dB down of 73Hz

0.2 cubic foot ported with 1.5" diameter port by 5" long for 3dB down of 61Hz

Note: The larger ported box goes deeper, but will have less power handling.

Just for fun, you might try this speaker as a full range.  With that extended rising response it might sound pretty good at higher frequencies.
