Room Acoustic Treatment

Recently, a few customers asked me about those audio systems' photos that I posted in Facebook. Then, the subject of acoustic treatment brought into discussion.

I was quite surprised that many still use acoustic panels especially those absorption panels without knowing the usage as well as putting it in the wrong place. Some have the whole front wall with only absorption panels. Bad idea.

There should be a degree of 'check and balance' when it comes to room acoustic. Over treat the room, it sounds dead in it. High frequency and mid frequency suffer. Your ears 'tell' you that there is a uneasiness in it. The sound no longer sounds lively.

Before going for acoustic treatment, one must know what is the issue that he is facing. Without knowing the problem, you cannot troubleshoot it. For a start, the basic fundamentals of acoustic treatment normally will be done such as corner traps and first reflection point treatment. 

We have touched on the topics of acoustic treatments in this blogspot. You may refer to it as a guideline.

I am glad that these customers heeded my advice by taking off some of the panels that were put in wrong places. They hear improvements in their stereo system as well as HT. Sometime more does not necessary means better.

Have a nice weekend.

SVS Ultra Speaker System review by Home Theater Magazine

"I have the deepest respect for what SVS has done with the Ultra line, and for this listener, where respect treads, pleasure and relaxation are rarely far behind. These speakers do everything well, and the more time I spent with them, the more I appreciated the way they could get the best out of any content in my library—free of gross flaws, too-obvious subjectivity, or little niggling quirks that grow tiresome in the long term." ~  Mark Fleischmann, HomeTheater.com

SVS Ultra Center channel speaker: Outstanding Vocal Reproduction, Room-Filling Presence and Outstanding Dialogue Intelligibility

“Dynamics of a custom theater system, neutrality and ambience of an audiophile system…Certified and Recommended.”

Brent Butterworth, Sound&Vision

SVS Ultra Center - The Foundation For High-End Home Theaters
The Ultra Center anchors the front stage and immerses the listener in the cinema experience, effortlessly handling the most complex and dialogue-intensive scenes with stunning realism, room-filling presence and outstanding vocal reproduction and dialogue intelligibility. Available in premium-grade piano gloss black and real black oak veneer finishes and handsomely styled with a swept back profile and striking edge treatments, the Ultra Center will complement any high-end home theater.

Dramatic Styling Yields Sonic Benefits
The Ultra Center cabinet design yields numerous sonic benefits. The non-parallel cabinet panels reduce standing waves within the cabinet, effectively eliminating frequency response coloration. The wedge-shaped front baffle and flush-mounted drivers reduce edge diffraction and improved on-axis high frequency response. Even the grille designn is FEA-optimizedd to maximize acoustic transparency.


SVS Drivers - Extreme Performance and Uncompromised Fidelity
The proprietary SVS drivers utilize the finest materials and design features to ensure the highest sound quality and performance. The Ultra Center driver array features a 1" aluminum dome tweeter, a 4" midrange driver, and dual 6.5" woofers. The vertically aligned tweeter and midrange improves horizontal axis polar response, with reduced lobing and comb filtering for a smooth frequency response and excellent dialogue intelligibility at all listening positions.

The 1" aluminum dome tweeter utilizes an FEA-optimized diffuser which delivers a very open 'airy' presentation and extremely unveiled highs.

The 4" midrange delivers amazing dialogue clarity and detail with powerful and room-filling presence and projection:

• A composite glass-fiber cone with excellent stiffness/mass ratio which improves sensitivity and maintains pistonic behavior well beyond the pass-band of the driver.
• A vented voice coil former to minimize air compression artifacts at high drive levels.
• An aluminum shorting ring to reduce gap inductance, lower distortion, and improve high frequency response.
• A cast aluminum basket to ensure precise alignment of critical components and enhance heat-sinking capacity.
  

The 6.5" woofer delivers excellent lower midrange clarity, along with remarkably powerful and deep bass response:

• A composite glass-fiber cone with excellent stiffness/mass ratio which improves sensitivity and maintains pistonic behavior well beyond the pass-band of the driver.
• A vented voice coil former to minimize air compression artifacts at high drive levels.
• An aluminum shorting ring to reduce gap inductance, lower distortion, and improve high frequency response.
• A cast aluminum basket to ensure precise alignment of critical components and enhance heat-sinking capacity.
  

SoundMatch Crossover Network - Intelligently Designed for Your Listening Room
The SoundMatch 3-way crossover features premium-grade capacitors, air-core inductors and heavy-trace printed circuit boards to ensure pure signal transmission. Careful selection of the crossover frequency and slopes results in a smooth off-axis polar response, outstanding phase coherency and a stable sound stage. 

 Frequency Response and Electro-Acoustic Data:

• Rated bandwidth: 45 Hz-32 kHz (+/-3 dB).
• Nominal impedance: 8 ohms.
• Sensitivity: 87 dB (2.83V @ 1 meter full-space, 300-3kHz).
• Recommended amplifier power: 20-225 watts.
