I have a pair of 2122H that I've been sitting on from the Tent Sale and rather than building cabinets have decided to mount them in .7 cu. ft. enclosures rather than the JBL recommended .25. What, if any, transient response negatives might I encounter in the larger box. They will be actively crossed over at 300 hz 4th order. And what was JBL's original application for the 2122H.
