TThis listing is for (1) new 15 inch PA woofer. I would recommend it for 2-3 way PA type setups requiring less than 500 watts rms, or a bass cabinet. It is very efficient in its sound at 98db (m/w), and does not require a huge amplifier to get great sound out of it. Customers have had good results using these as replacements with little to no modifications in Electro-Voice Eliminator folded horn, Behringer, Yamaha, Legion, Klipsch, Peavey Black Widow, Kuston, Legion, JBL TR225, Standel Studio 100, Bass Guitar Cabinets, and more. Please note this listing is for (1) woofer. This is a standard size 15" so it should work for many applications, please double check your measurements before ordering. For more info on this woofer, please see below. This woofer is brand new in box.
