The M40 is a powerfull and elegant 2.5-way, ﬂoor-standing speaker. The speaker features a high-resolution ribbon tweeter, normally only seen in much higher priced products. In the M40, the tweeter blends seamlessly with two 4" honeycomb enforced glass-ﬁber midrange/ woofer drivers, arranged in a MTM conﬁguration. The two midrange/woofer drivers are supported in the lower frequency regions by an array of 2 dedicated bass drivers. Don't let the slim and elegant looks fool you - the M40 can really rock the house, when it's four 4" woofers are put to work.
