The brain has no option but to interpret that there are real living people playing real musical instruments, playing in the very room in which, a millisecond ago, contained nothing more than your stereo system. The sensation of hearing "natural" sound is overwhelming. The exact size of all the instruments and vocals, their perfect position within the sound stage, and the clarity of air between the instrument's positions are all instantly recognizable? Enough said.

The 9" Raal Lazy Ribbon is a super detailed and super efficient ribbon tweeter.  The high efficiency makes this a perfect choice as a tweeter or super tweeter for horn systems or other high efficiency systems.  Ribbon tweeters are a dead short to the amplifier, so you need to use a passive crossover on the tweeter.  HighlightsAluminum ribbon supertweeter with an amorphous C-core transfoRibbon surface of 20cm2Impedance of 3.5 - 5 - 7 - 10 - 14 ohms selectablePower handling (RMS) of 200 WFrequency response between 3000 - 50000 HzSensitivity between 105 - 106.5 - 108 - 109.5 - 111 dB selectable Product details RAAL 210-10 Flatfoil Ribbon Tweeter The RAAL 210-10 Flatfoil Ribbon Tweeter is a high-end tweeter that is known for its excellent sound quality and high efficiency. It features an aluminum ribbon supertweeter with an amorphous C-core transfo and a ribbon surface of 20cm2. The tweeter has an impedance of 3.5 - 5 - 7 - 10 - 14 ohms selectable and a power handling (RMS) of 200 W. The frequency response is between 3000 - 50000 Hz and the sensitivity is between 105 - 106.5 - 108 - 109.5 - 111 dB selectable. If you intend to use an electronic crossover, you still need to use a large capacitor in series with the tweeter, in this case perhaps a 30mfd. The tweeter has different soldering points in order to adjust the tweeter output level.Show more Show less

True ribbon drivers are well known by their ability of exceptionally fine rendering of the details in music material. They work in a different way than conventional dome or ring HF driver, relieved of all the excess baggage, so to speak, and they do their job better than anything else, regardless of the price tag. HighlightsSpecial FLATFOIL pure Aluminium ribbonSpecial SYMMLEAD low inductance signal pathSpecial EQUAFIELD NdFeB magnetic structureSpecial ''non-wave-guide'' INOX front plateSuper-fast settling timeFlat frequency responseLow nonlinear distortionHigh signal power handlingHighest reliability Product details RAAL 70-10 Flatfoil True Ribbon Tweeter Tremendous acceleration of air is available with RAAL 70-10, more than 13000 G, and in less than 200 microseconds after, that air is stopped. That brutal controlling force combined with the smoothest response available and bandwidth of 100 kHz, can ensure you that the weak link in any system equipped with it, will not be the HF driver. It will show the differences between the electronics or cables without any effort by the listener. The better the electronics chain before it, the better the sound will be. The sound? Well, some people still can't believe what they can hear with it, for the fist time ever, in their well known music material. That comes as standard with, pretty much, all true ribbons, but the effortless recreation of real dynamics, and amazingly high SPL levels for a ribbon of that size, was not known before RAAL 70-10. It doesn't get intimidated by the big amplifiers. If you have clean power, feed it to the little fellow, and you will be stunned by all the music you have, presented in another dimension of reality. If you don't have power, and/or you don't like it, then discover the abundance of detail and true colour of any instrument played in a brand new, engaging manner. No domes, rings, suspensions, coil formers, glues, damping material, not even the lacquer insulation on the wire of the coil. No heavy plastic carrier foils, like in cheap quasi-ribbons. Only 0.004 mm (0.00016 in.) thick aluminium foil, immersed in strong magnetic field. And yes, the best quality of HF region, and real, breathing, micro and macro dynamics gives a totally new sense of what the musician(s) wanted to say. It will make you forget that the system is in front of you. The music will come to life.Show more Show less

World's smallest form factor for a true ribbon of just 1.8 kHz cutoff frequency, reliable, able to handle a lot of power, sounding like it doesn't exist... All that by using only one series capacitor as a complete L-R 4th order crossover at 1.8k, combining acoustical and electrical slopes, with minimum of added passive crossover components. Featuring three transformer taps for resistorless sensitivity adjustment, ribbon replacement kits, custom front plates, copper soldering posts. All of it, makes it perfect for reaching new limits in high-end home stereo or multichannel and near-to-mid field studio monitoring applications. It was developed according to the wishes of the most demanding manufacturers, that were looking for a quantum leap in true ribbon design. Highlightsigh fr.
