Has anyone been silly enough to make an 18” combo? I ask because a have a spare driver kicking about and I’m tempted to give such foolishness a go. The driver is the inexpensive qtx unit: https://www.simplysoundandlighting.co.uk/qtx-18-low-frequency-driver/ For an amp circuit, thinking something single ended under 20W (yep, I know it’s a 350W driver). Will need to push the treble a bit, so can implement a presence type control in the feedback. To do or not to do?
