I'm selling my CS2.3s. I'm moving into SETs. These have been great speakers throughout my ownership. These are the originals that I bought from Clayton Shaw. The creator and original owner of EP. Each speaker has (2) 15's and a concentric driver which consists of a compression horn driver in a 12" bass/midrange woofer. These are Black Oak in color they come with the DSP2.4 MiniDSP crossover modules. Look for the reviews on these beauties. You will be surprised what's said. There are a few different options available on how to operate these, and the modules can be programmed for any way you choose to operate them. Fully active with stereo subs... Or, perhaps one amp for the coax and one for the 15's... This creates an excellent way to upgrade. I do have the original boxes. The speakers are VERY fun to listen to! Very engaging. PayPal fees and S/H/I negotiable.
