Description
The 218 R is the big brother to our 215 R subwoofer. The band pass/ direct radiator combination of the front baffle results in a tight punchy sound with more extended low frequency than the 215 R. This box is designed to shine where there is a high output need with a minimum baffle area. The use of two high-power 18″ woofers with 4.5″ voice coils results in low power compression and excellent efficiency. The 18″ subwoofers are housed in an enclosure of truck pack dimensions.
There are two additional versions available in addition to the tour version shown here. There is an Ultra-High Power version of this tour version that boasts 6400 Watts Program power. The 218R is also available in a “stage version” and designed with a stage’s limited floor space in mind. The 218 R Stage has the same price and identical performance of the 2-18-R.
