In pursuit of higher fidelity

A browse of online forums can veer between handy and deeply disturbing, but I did glean a useful consensus on Xbimmers.com regarding the X1’s standard audio system. Forum contributors all agreed that the sub-bass drivers mounted in the floor under the front seats are too small and underpowered, and are a prime upgrade point. Broad consensus was the Harman/kardon option was well worth the spend. And not expecting miracles from digital recordings more compressed than Clive Palmer in a body stocking.
