#Klipsch kg 4.2 review driver#
The midrange driver in the Klipsch Heresy IV does not do this.Instead, a small 45mm diameter diaphragm (made from a synthetic material called polyimide) compresses the air in a small chamber, and it’s the resulting flow of air into and out of that chamber that in turn moves the air in the room.
#Klipsch kg 4.2 review drivers#
The midrange drivers used in most hi-fi speakers are what’s called ‘direct radiators’ – a description that comes about because the back-and-forth movement of the diaphragm (which is usually a cone, but is sometimes a dome and, occasionally, a flat panel) moves the air in the room directly. Take particular note of the words ‘compression driver’ in the previous paragraph because it’s a special kind of driver that is very rarely used as a midrange driver in home hi-fi speaker systems. That new midrange driver is a polyimide-diaphragm K-702 midrange compression driver, which is loaded by a K-704 Tractrix horn and covers the audio band from 850Hz up to 4.5kHz. Its distortion has been reduced because the updates to the midrange driver meant Klipsch engineers could let that driver take over some frequencies previously handed by the tweeter, so they dropped the crossover point between the two by 500Hz (from 5kHz on the Heresy III down to 4.5kHz on the Heresy IV). Then there’s the tweeter, which has the same titanium diaphragm as the III, but is now fronted by a new phase plug that the company claims enables much wider high-frequency dispersion and in turn a more expansive ‘sweet spot’. According to Klipsch’s Australian distributor, this change alone has improved the Heresy IV’s low-frequency extension by 10Hz, with Klipsch specifying the 4dB down-point at 48Hz. What’s not so surprising is that rather than use a conventional tubular or rectangular bass reflex port, Klipsch has instead pressed into service one of its famous ‘Tractrix’ horn throats. One of the most significant of these changes is that it’s now a bass reflex design. This Klipsch Heresy IV model is not only completely different to the one introduced in 1957, it’s also substantively different from the III version that was introduced in 2006. Klipsch Heresy IV (Klipsch) at Amazon for $3,198.The best speakers available right now: budget to premium.I still think the more modern products are pretty decent, too. And, back in 1982, Klipsch's small speakers had the same build quality as K Horns. In any case I love these little speakers, they make a watt go a long way and they have a very sweet sound. Sometimes small speakers take a step in the wrong direction when their designers try to expand their capabilities on the bottom end. None of the boomy sound on acoustic or electric bass in Jazz or Rock recordings. The main thing about the original KG2's was just how tight and controlled the mid bass was. (Guess I shouldn't have had the speaker sitting on the same shelf as the turntable! It was a very small room.) Before I bi-amped them I cooked them twice with a Denon 60w integrated amp. The original versions sound especially good when bi-amped and crossed over 70-80Hz. The midrange definitly got a little thinner and the bass got a little boomier when they added the passive rad. I have the original version which I bought in 1982 or so. I just wanted to point out that KG2's were a little different before they added the passive rad. The horns are much tamer (smoother) in these "Classic" Klipsch loudspeakers, and don't have the overly boomy bass that the new ones tend to have. Now with the Heresy's it isn't an issue (Horn tweeter, horn mid, 12" accustic suspension woofer). The 2-way design lost a little in the over lap between drivers when going for bass extention. One weakness of the KG2's was a thin midrange. Well I've since added a pair of Klipsch Heresy II to my system as fronts and moved 2 of the KG2's to the rear and have a very well balanced HT. A perfect match to the ones I already had, what luck! Anyway, about 1 1/2 ago I found another one for sale (not a pair, just one) so I bought it to use as a center speaker in my HT system. I got them from Sound Goods in San Jose California, even got to meet Paul Klipsch there once. When I bought these Klipsch was still a boutique speaker. I feel that they are a much better sounding speaker than Klipsch is putting out today. I have been very impressed with these speakers and still am when I compare them to what is available now. They have survied 12 years with me including going back and forth to college. These speakers are very effecient and can be driven with just about anything.
They have a very wide and detailed sound stage. They are extreemly dynamic with excelent bass extention for a small speaker. Saved up from my summer job and got them. I was 16 years old and it seemed like an awful lot of money to me them. I was surprised to see that no one else had any experiences with this little speaker.
