I´m choosing between a bagend s15d and an Ashdown ABM 410. They are both rated at 103 dB @ 1W/ 1m. I know the bagend has less conearea and therefore move less air and they don´t have the same frequencyresponse. But how much volume will I loose compared to the 410? Will it be a big difference? My main reason for wanting the bag end is the weight and it´s great reviews. I can always add another s15d when I can afford it but it would be great to have a 44 pound speakercab in one hand, my Ashdownhead in the other and my bass in my gigbag on my back.
