This is a cool cab. I believe that Peavey does not currently make 2x15s for bass. They original speakers were not included when I bought this so I replaced the Fisher (yep, that's right!) crap with some Pyramid 600w 15s. These are brand new 4 ohm, 600w RMS/1200w peak (according to my manual) wired in series to give the cab a total impedance of 8 ohms. The SPL is rated at 89. I have played them with my R600 head and a old 100w PA head and they sound very "true" to the original, unamplified sound to me. The cab is light for a 2x15 and includes casters for easy moving. If you live anywhere in Southern Cali you are certainly invited to check it out!! Just send me a PM.
