I purchased the VA Mahler several months ago and found it to be an outstanding speaker for anykind of music. I listen to rock, jazz, classical etc. and have found them to perform well with all. I feel the midrange and treble reproduction is as good as you could possibly want. Vocals sound as real as possible with the soundstage being very wide and deep. There is much air around instruments giving each sound within the stage a much better image. The lower octaves perform very well. I would think that you would need a subwoofer or at least much larger speaker to outperform the lower octaves. The quality of the lower octaves will be dependent upon the room and placement. As mentioned in one of the previous postings you need a mid to large size room for these to perform their best. I have my front woofers 40" from the rear wall and the speakers are about 4' from the side walls. With this positioning the bass in my system is very deep and tight. As you can tell I am a satisfied owner of these speakers. I am sure that there are better speakers but I have yet to hear them.
