This modular hybrid active system consists of two units coupled together to perform seamlessly as one. On top is our acclaimed second-gen passive Pi monitor that can be ordered with drivers of your choice. On the bottom is the mighty Pi-Bass. A woofer extension system that combines the Ripol® speaker design philosophy with our proprietary Acoustic Stealth Technology®. The result is a fully open system that moves close to zero air volume allowing for free placement within a room. The lower Pi-Bass module is equipped with 2 x 96dB neodymium woofers each (=99dB). These woofers are extremely fast and are driven by a 250W class A/B plate amp tuned by our electronics team. Given this unique combination, this system runs semi-active in that the Pi monitors on top need no crossover and are fed directly from the high-level speaker cable taps from a complimentary amplifier like our Voxativ T-211 Integrated (the perfect pairing). The bottom Pi-Bass woofer module has it's own amplifier and can be driven up to an onboard crossover setting of 120 Hz (recommended) with a full range of EQ to blend into any room. We suggest a line-level RCA connection from your preamp to the Pi-Bass for highest fidelity (although a high-level speaker cable connection is also possible.) The result is the most powerful full-range system the industry has ever experienced linear down to 20Hz in low-frequency slam. >> TECHNICAL DATA Frequency Response 20 - 20.000 Hz Driver VOXATIV AC-PiFe or others Efficiency max. 110 dB / 1W / 1 m Capacity 50 W sinus Dimensions (W x H x D) 16 x 47 x 16" (40x120x40cm) Color Piano Finish, white or black Weight 150 lbs (67kg) But it's not a single driver system !! 2

It's a single driver speaker in a shiny black box sitting on top of a sub woofer. "OOPS" i mean "a woofer extension system with Ripol speaker design philosophy and proprietary Acoustic Stealth Technology" Which they then claim moves almost zero air??? Huh, and the clincher "extremely fast woofers" (Acoustic engineers joke for whats a fast woofer= a tweeter!) Who writes this stuff? 1 1

TomAus Posted February 12, 2020 Posted February 12, 2020 A spectacular speaker deserves a spectacular listening chair. This is from Dutch speaker manufacturer Kharma. 1 2

I'm not aware of any recommendations as I imagine this would depend on several different factors. However, they do provide some information about it's functionality on their website. From their website: "The Kharma Listening chair is specially sculpted to enjoy a musical performance in every way. The chair in its upright listening position brings an active posture to unravel a musical masterpiece, while it can also be transformed to a laidback lounge chair to forget the world around us and enjoy our favourite music. By just a touch of a finger, you control the built-in motor to settle into your desired position."
Steever Posted March 18, 2020 Posted March 18, 2020 Mission's Pilastro. 52 pairs made. Does anyone know if a pair made their way down to Australia?

Tony M Posted March 21, 2020 Posted March 21, 2020 (edited) So, this is a thread about spectacular speakers. Well, the pic I have attached comes from the Victorian Real Estate pages and the standard pair of Duntech Crown Princes, as worthy as thay are, hardly meet the definition of "spectacular". But, it seemed as good a place as any to show a gorgeous picture of a pair of speakers looking totally at home in the perfect context of a piece of superb 70's architecture. To me the overall effect is spectacular as it looks like a place I'd love to spend time in and a home I'd really enjoy living in. Perhaps a function of my age demographic, but good 70's architecture does it for me and the CP's just add the perfect finishing touch. PS Anyone care to identify the electronic components?

Well spotted and your analysis is borne out by some of the earlier responses in this thread. As you say, it is clever marketing – which of course is designed to attract our attention in the first instance. I use a field coil version of this Voxativ 9.87 speaker system and am very happy with their performance – in spite of it obviously not being a single driver system. That said it must be acknowledged that most of its output across 8 octaves IS generated from a rear horn loaded single driver.

You could also say something like “anyone who thinks you can’t get perfect stereo imaging from a single speaker has simply never experienced our award winning 2-speaker system” 2

I may may be interpreting 'Spectacular Speakers' incorrectly, but in my mind, they must be visually arresting/pleasing etc. and I would hope they sound as good as they look! Make up your own mind, do they fit in this thread? (The pair above = my favs!) Kind regards, Michael I agree, the aesthetics are a huge part of the pleasure of loudspeakers, and of course the audio quality needs to match and visa versa. I'm collaborating to build a set that meet this dual criteria and I would LOVE to get some Mukassar (ebony) type veneer with that great contrast. Any idea how to source that in Australia given your woodworking knowledge? Thanks
Guest DrSK Posted July 25, 2020 Posted July 25, 2020 (edited) I'm suspicious whether some of these flares even work. Sometimes doesn't take much before the horn is effectively terminated before the physical end of the horn due to extreme changes in flare and abrupt angle changes. There were some massive home built horns on stereo.net shown at an art exhibition that seemed to have this issue in their response. I had to design and build a horn once to test automotive component insertion losses where I had to eliminate end reflections as they interfered with the measurement (so you need to efficiently radiate all the noise away, like in a horn speaker). Found issues in the ISO Standard I'd been asked to use, which was also an issue in some ANSI test procedures. Ended up doing first principles design. Even just transferring abruptly from round to square is enough to cause issues. Ended up turning square bar in a lathe to create a tapered round to square transition plug shape, which I then waxed and wrapped fibre glass around. When set, popped the plug out and added the fibreglass transition into the build. Edited July 25, 2020 by DrSK
