  • Aerial Acoustics System 1 speaker package

    Aerial Acoustics System 1 speaker package

    Aerial Acoustics System 1 speaker package including two subwoofer amplifiers AERIAL SYSTEM 1 Modern problems often require innovative solutions. For example, how does one recreate remarkable movie and music experiences at home without giving up precious living space to room-dominating loudspeakers? Let us introduce you to the Aerial SYSTEM 1. SYSTEM 1 is an exceptionally capable multi-channel speaker system that surrounds large format video screens to form an integrated unit only twelve inches deep and barely wider than the screen itself. An impressive assemblage of audio technologies, SYSTEM 1 employs twenty-five custom-designed drivers within its high-performance left, center, and right channel loudspeakers and twin high-output subwoofers. Legendary Aerial performance is discreetly integrated within a slender, unobtrusive unit. Its modular design allows SYSTEM 1 to accommodate video screens of different sizes, types and aspect ratios. Whether your screen has an HDTV 16×9 or CinemaScope 2.35:1 aspect ratio, is flat or curved, or incorporates variable masking, each SYSTEM 1 includes everything required to create an assembly seemingly tailor-made to your specifications. What’s more, unlike completely customized built-in systems, the adaptable SYSTEM 1 can be moved to a different space or re-sized for a different screen. A neutral aesthetic design allows the SYSTEM 1 to blend with any décor. Equally important, it does not compete for the eye’s attention to images on the screen. For all its practicality, the SYSTEM 1 provides a decidedly emotional experience. Its personality is lifelike and dynamically expressive, with a clear and natural midrange voice, airy extended upper frequencies, and powerful extended bass. Both music and film soundtracks are rendered in an inviting, engaging, and thoroughly enjoyable way. The Aerial SYSTEM 1. It’s that simple. All sort of options available including Stewart screen, Aerial rears and control system separately. Learn More

    Sunfire True Subwoofer MK II just serviced

    Sunfire True Subwoofer MKII just recapped Sunfire Background Bob Carver, the man behind the success of Phase Linear and Carver Corporation is the mastermind behind this subwoofer-that-could. The son of an engineer and concert pianist, Bob Carver was predestined to become one of the major pioneers of the high end audio industry. He introduced the legendary solid-state Phase Linear 700 amplifier in the mid-seventies, one of the first truly high powered consumer amplifiers. Sunfire Corporation was founded in 1994, Carver's third company, and once again he is breaking new ground. The first product off the blocks was the Sunfire amplifier, which followed in the Carver tradition of big power. The distinctive technical aspect of the Sunfire amplifier is its tracking down converter, or tracking power supply, which monitors the signal, and supplies the necessary power to the output devices as demanded by the signal. According to Carver this design allows the amplifier to deliver more power and current, efficiently. Incorporating the tracking down converter, the Sunfire True Subwoofer has the distinction of being the smallest, most powerful subwoofer in the market today. Sunfire True Subwoofer Design The Sunfire True Subwoofer is housed in an 11" cube, powered by a built-in 2,700 watt amplifier with two 8" drivers on either side of the enclosure. It is rated flat down to 18 Hz, reproducing ultra low bass frequencies at 110 dB SPL. To have deep bass and lot's of it, you must move a tremendous amount of air. Air movement is measured in cubic inches. The more cubic inches of air that is displaced the more bass you can produce. For wall rattling and floor shaking bass you need to displace at least 135 inches of air. Sunfire's push-pull design allows the Sunfire True Subwoofer to displace 251 cubic inches of air! For comparison, your average fifteen inch woofer only displaces 66 cubic inches of air. The dual driver design also cancels the internal forces of such a powerful amp, preventing it from hopping around the room. If you want all the details on how the Sunfire True Subwoofer achieves what seems to be the impossible at first glance, take a look at their white paper which can be found at http://www.sunfire.com. The Sunfire crossover is variable from 40 Hz to 120 Hz with a slope of 36 dB per octave. There is an input level control with continuously adjustable phase and a passive 70 Hz, 6 dB per octave hi-pass line level output for satellite loudspeakers. The input coupling is optical and accepts standard and high level inputs. Learn More

  • Velodyne HGS 12 confirm availability before purchasing

    Velodyne HGS 12 confirm availability before purchasing

    Although we recently published a review of the Velodyne HGS-10 subwoofer, the innovative technology that is inherent to this new class of subwoofer warrants a review of their latest edition, the HGS-12. We understand that subwoofer aficionados in our readership want to know about the 12" version, and it will be some time before reviews appear in the printed trade. So here goes. The HGS-12 (HGS stands for High Gain Servo) has a 12" driver with a 19.3 pound magnet structure and 3" tandem push-pull voice coil. Front of Driver (3750 bytes)This is the same driver as in the FSR-18, without the bucking magnet. It is also the same driver as in the HGS-10. HGS AmplifierVelodyne is quite pleased with the new driver design and is using it in all of their high performance servo-feedback subwoofers, with the cone sized accordingly. I really enjoy our F-1500s and FSR-18s, but they are BIG. The HGS-10 and HGS-12 will fit nicely behind the couch if necessary. Is the size of the box that important as far as being furniture-friendly? Apparently so to a lot of people. But the problem has been in getting high performance from a small enclosure. Enter the HGS-10 and HGS-12. In the HGS-12, the piston size is 11", and the actual edges of the mounting rim extend the total driver size to 12". A large dust cap makes the driver shallow. An enormous rubber surround allows for large excursion. The sub is powered by their new digital switching (Class D) amplifier (140 kHz switching frequency at the output stage), rated at 1,250 watts rms (that's a LOT of power!) into the driver which dips to 3.2 Ohms. Servo-feedback technology is utilized (solid state motion detector mounted near the voice coil), as is on all Velodyne high performance models. Panel (3396 bytes)There are 78.6 joules of energy storage capacity in the power amplifier. On the back are an ungrounded AC socket, RCA line-level inputs and high-pass (80 Hz, 6 dB/octave) outputs, Volume control, Low-Pass crossover control (40 Hz - 120 Hz, 12 dB/octave initially, 48 dB/octave ultimately), Crossover in/out switch, Phase toggle (00 or 1800), Subsonic selection (20 Hz or 35 Hz cutoff), and a remote sensor socket. The enclosure is nicely finished in gloss black polymer veneer. For testing (listening and measurements), we placed the HGS-12 on the floor, 2 feet out from a wall. The 20' x 20' testing lab has wall to wall carpet, and no windows. The HGS-12 complimented our McCormack CD system, McCormack ALD-1 Preamplifier, LLano Monoblocks, and Threshold ES-500 Electrostatic Speakers. Cables were Nordost SPM Reference and Nordost Red Dawn. For room response measurements, the low pass was set to 120 Hz, the crossover switch was set to "In", and the subsonic cutoff was set at 20 Hz. The volume control was at mid-level. Room Response - Velodyne HGS-12 Subwoofer -- Grille off -- Set to 90 dB at 20 Hz -- (This is not maximum output, but rather just the response in an "average" room with the volume set to 90 dB at 20 Hz.) 1 meter 13 feet 10 Hz 72.7 dB 10 Hz 82.4 dB 12.5 Hz 69.0 dB 12.5 Hz 86.4 dB 16 Hz 80.6 dB 16 Hz 92.1 dB 20 Hz 90.4 dB 20 Hz 90.7 dB 25 Hz 93.8 dB 25 Hz 98.7 dB 31.5 Hz 97.3 dB 31.5 Hz 103.6 dB 40 Hz 88.1 dB 40 Hz 104.4 dB 50 Hz 95.8 dB 50 Hz 101.2 dB 63 Hz 92.3 dB 63 Hz 107.0 dB 80 Hz 93.3 dB 80 Hz 94.0 dB 100 Hz 93.2 dB 100 Hz 98.4 dB 125 Hz 85.9 dB 125 Hz 97.9 dB 160 Hz 81.7 dB 160 Hz 87.4 dB The HGS-12 has usable output down to 16 Hz (farfield). Even in the deep regions at high output, we could hear no harmonics, and our Spectrum Analyzer showed no harmonic peaks within about 20 dB of the fundamental (the sinewave test frequency). We could get 112 dB SPL nearfield at 31.5 Hz, which is similar to an F-1500, before limiters set in. I never heard the HGS-12 amplifier clip. That isn't to say that it can't be done, but the limiters keep this from happening under normal circumstances. This new digital switching amplifier stuff is really amazing! The built-in amplifier remained stone cold even after extensive use at full output. Notwithstanding problems they might have with full spectrum sound, they sure make dynamite amplifiers for subwoofers! Our ES-500 Electrostatic Speakers are full range units, and even though they respond to quite low frequencies, it is hard work. I used our Mirage LFX-3 active crossover to attenuate frequencies below 50 Hz in the electrostatics, and the HGS-12 made a huge difference in the overall sound presentation. The electrostatic panels were alleviated from having to handle the lows, making them perform better in the mids and highs, while the HGS-12 moved all the air necessary to make the wall studs shudder. Of course, the HGS-12 was great with home theater material, but putting this sub with the $11,000 ES-500s was illuminating as to its high performance capability in the realm of classical music. Powerful, deep, and clean. Nothing else needs to be said. In summary, the HGS-12 is the big brother to the HGS-10, and both are new additions to Velodyne's line of servo-feedback subwoofers. Although neither of these products will stomp on the Velodyne FSR-18, the HGS-12 sure will make you scratch your chin when deciding between it and conventional 15" subs. Learn More
