Both are for sale. These were installed in a demo and we just removed them. Prestine conditionl, no high level speaker input clips though, and manuals in paper form. Do have manuals in PDF. files which we can provide. Would like to sell as a pair and the price is excellent for them. 6XS has the Subwoofer knob and cable but no bracket. 6XS has a tiny tiny blemish on the edge which is barely noticeable in the pic and has 12 or so chips, 50hz, 60hz(2x), 80hz(2x), 90hz(one 90 hz chip is in the front low pass at 18db slope)(3x), 150hz(2x), 250hz, 350hz(3x), and 3.5khz. All chips other than the 90hz noted are 24db slope chips. EQS has SSF 33hz @18db slope. 350$ shipped in 48states for the pair. Pics are available.
