Nipped into into my local store before as i've popped one of the front speakers in the Slaguna and i'd noticed they had a sale on (and i was passing anyway!). Looked at some co-axial Kenwoods and thought they sounded a bit tinny, tried a component set of Infinity's and was really into them, thought they sounded nice with good bass...until i realised they weren't the only speakers going.
Switch back to the cheap Kenwoods and yup, its just them on. Back to the Infinitys again and for sure there was another pair of speakers going...did it with one of the other pairs i tried as well. A ploy to get you to hand over your hard earned for more expensive stuff, surely not?.
