Visaton's 9023 W130S 5" woofer features a coated paper cone and durable rubber surround. A very balanced frequency response allows the W130S to be used as a woofer in small two-way speakers or a midbass/midrange in three-way speakers, with a crossover point as high as 4,000 Hz. This allows you to build a surround sound system with large speakers for front and left, while maintaining the same voicing in smaller surround satellite speakers.
Note: For best bass performance, install the W130S into one of the following cabinets:
• A 0.25 cubic foot sealed cabinet (F3 is 86 Hz with a Qtc of 0.75).
• A 0.71 cubic foot cabinet tuned to 44 Hz with a 1-1/4" diameter port that is 1-9/16" long.
• A 1.06 cubic foot cabinet tuned to 39 Hz with a 2-3/8" diameter port that is 4-3/4"" long.
