SAP-18SFF Empty - 18" Empty Pro Audio PA/DJ Subwoofer Cabinet

Great cabinet

Very well made. No deformations or knots seen from the inside. These are braced up exceptionally well I would recommend these to anyone who wants to put their own speakers in a cabinet. The shipping was very fast and the support, when I called was exceptional. This is a very good company to deal with.

18 empty sub box

Seismic audio Rocks I like these sub boxes because there inexpensive and strong ,,I can add more as needed I like to put neodymium 18” woofers better on my back thanks again.

sound support!

I bought (two) 18" sub-cabinets, with built in cross over to support the 15" powered speakers I already had to make a very impressive "Tower of Sound", I used Peavey 18" Black Widow's in my cabinets. The design, baffle boars, and construction of the cabinets are very good!, I added caster wheels to mine so they could be moved easier. very affordable on a working musicians budget!
