I have a pair of Lanshe 4.1 speakers with brand new plasma tweeters in the optional high gloss finish. This speaker at this price point is a steal and an absolute no-brainer at less than 1/3 the cost of a new pair. The high grade AAAAA birdseye maple finish is an absolute stunner to look at and trying to explain to your friends how the glowing ball of electricity is creating the sound they are hearing is priceless!
The new plasma core tweeters have around 50 hours on them and average life is between a low of 5000 to a high of 7000 hours. If you listen a few days a week at a couple of hours each day then you will use around 200 to 250 hours per year. That should give you 16 years before needing to change a tweeter (which will cost you around $2000).
Here are several links for reviews:
The Lansche 4.1 is a lighting fast semi-active loudspeaker (two active 10 inch sub woofers in each speaker) with 8 ohm impedance and a 99 db efficiency. Very tube friendly! The frequency response is 25Hz-150KHz and the tweeters are 8mm Corona-Ion plasma transducers for amazing high end extension, the likes of which you have to hear for yourself to believe.
These loudspeakers will be sold with the optional flight cases ($3,200 a pair) included in the price. These Aluminum flight cases are padded and very strong so your 4.1's will be well protected on their journey.
I prefer a local pick up in NYC but will ship as well. Just be aware that these weigh in at around 160 lbs each without the flight cases so shipping will be costly.
