The World's Largest Online Seller of Hi-End Audio ...


$125,000 NEW - BUY FOR $49,900 OFF AND SAVE 60% OFF!!!
Buy From A Safe Seller - We've Been On eBAY Since 1998 !!!


HigherFi is the largest seller of ultra high end audio in the world
and we are excited to be able to offer this ultimate audiophile pair of speakers from Siltech.

We offer for sale a truly special pair of SILTECH statement speakers, one of only 39 anniversary edition pairs in the world, and the first pair sold, serial number 00A and 00B. Offered in exceptional condition with all original factory boxes they speakers can be shipped worldwide - shipped from our overseas office in Europe by AIR only to a buyer anywhere in the world so please allow a little extra time for packing and shipping.

The Siltech Pantheon is the flagship speaker for Siltech. Weighing 310 lbs and standing 63" tall, the speaker combines a pair of isobarik-arranged 16" Audio Technology woofers in a large, reflex-loaded bass bin with a 7" AT midrange unit in a separate enclosure, and a curved, 19" x 5" electrostatic tweeter. Internal wiring is, of course, all Siltech G7 silver-gold alloy, and the fourth-order crossover features 5.5 lb air-core inductors and high-quality capacitors.

The woofer tuning is unusual, in that the design goal for the system Q was very low, 0.5 with the port open, 0.38 with it closed. This overdamped alignment, optimized with extensive computer modeling of the speaker's interaction with the room acoustics, is essential, Edwin van der Kley feels, due it its tuning not being adversely affected by room resonant modes. Even with this low Q, the Pantheon's bass extension is said to be a low 18Hz, –3dB. The speaker's overall directivity is said to be carefully controlled. All the design work was performed using a set of $45,000 analytic programs from Comsol in Sweden designed for NASA.

The very low-mass, high-sensitivity tweeter has a diaphragm just 0.03mm in thickness and is specified as having useful HF extension to 39kHz..

YES ... we can ship worldwide (by AIR only) and arrange delivery to your door so no matter where you are, these speakers can be in your home no matter where you live.

Here is what some of our past customers had to say about us:

Having been an audiophile and a reviewer for over ten years, I have dealt with many people in the industry. My experience with Chris Moon of HigherFi was one of the smoothest, hassle free experiences I have had. I'm sure we will work together again soon. Thanks,
Greg Petan, Managing Editor/

"HigherFi is an honest, forthright seller of used high-end audio equipment. I have known Chris for over ten years and he has always been above board, knowledgeable, and a very good communicator. I would surely recommend him to anyone looking to sell very high-end audio components on a world-wide stage. I'm not sure there is anyone in the business today that's sold more gear in the uber-end of the market. What else can I say? Highly recommended!"
Jeff Fritz , Reviewer with UltraAudio
"I had the pleasure of setting up a Genesis 1.1 Loudspeaker system with my buddy that was purchased through HigherFi. The buyer was very happy and we had a blast dialing that system in! Chris seems to have all the great toys and the knowledge to get them pumping out fantastic music."
Michael Mercer, HPSoundings and Positive Feedback
My experience with HigherFi was fantastic [they sold my Halcro DM-88's amplifiers]. Their response was quick and detailed. Although we are located in different countries there was no problem throughout the entire transaction. I would definitely recomend working with them.
Ken Chee (Hong Kong)
Chris, many thanks for facilitating my purchase of the Wilson X-1 Series 3's. The speakers were just like new, as you said they would be, and your post-purchase advice about setting them up in my room has been extremely valuable. You made a deal happen that neither the seller nor I would have been able to make happen by ourselves ... but you made it happen. Thanks.
Professor L. Schwarz - Purdue University (USA)
Second experience with Higherfi ... no problems at all. I paid in advance, and everything arrived in time and in great conditions. Now, I take more than ever pleasure to listen to music with these fantastic FM Acoustics amps and like Chris said to me, "FM Acoustics makes my ears smile" I highly recommend HigherFi
Cédric Jouan (France)
I just purchased the Wilson Wamm speakers (retail $220,000) from you at HigherFi and could not be happier. After wiring the funds in advance, you made everything happen smoothly and professionally. I would not hesitate to buy from you again or recommend you. Thanks for a smooth deal!
R. Lapporte (USA)
Buying a pair of PMC MB2i XBd speakers from HigherFi  was a smooth and hassle free process. Chris Moon was prompt in communication and facilitated each stage of the transaction. The speakers arrived in perfect condition and needless to say, I am thrilled with them! Highly recommended!
