Teh DSP8024 and the DEQ2496 are autoEQ devices, but they are based on 1/3oct autoEQ for the graphical EQ.
Not very useful in the LFE region because 1/3 oct is too coarse for any useful EQing for bass. PEQ is a better EQ for bass fequencies because certain bass peaks can be much much narrower than 1/3oct.
The Behringer products are also not very accurate in the deepest bass, when using Auto EQ ... They ARE very good for fine tuning, IF you can figure out how to set one up.
Most guys cannot, so I stopped recommending the Behringer... not because I did not like it, but because the guys who DO understand it don't need my help... ... They are already quite adept at getting good sound.
I think you are talking about add-on devices, however, Velodyne is apparently going to release a software upgrade for its DD series that will add automatic equalization to the prodigious electronics package in the DD line. The DD is a premium product with a premium price. The DD 18 is one of the greatest subwoofers of all time and is arguably the sub of choice at a street price of around $3,600. Nothing else combines the performance, the convenience, the looks, the ease of use, the feature set.
