An old retail truth holds that great audio makes a TV look better - and today's immersive sound technology proves those veteran salesmen right. Dolby Atmos, DTS-X, and AURO 3D move far beyond 5.1 surround, adding height channels and object-based placement to wrap listeners in a genuine three-dimensional sound field. Entry-level Atmos systems start under $500, Blu-ray titles are already shipping, and the upgrade path is simpler than you might expect.
High-resolution audio has arrived in your pocket, and it sounds nothing like what you expect from a smartphone. Devices like the HTC One (M8) with Harman/Kardon audio and the LG G2 now pack DAC circuitry capable of decoding 192kHz/24-bit FLAC files, delivering studio-quality sound through a humble 3.5mm jack. Industry engineers, mastering legends, and record label pioneers gathered in New York to prove consumers can finally hear exactly what professionals hear in the studio.
KEF Speakers representative Jack Sharkey walks through a six-part series on transforming an acoustically problematic room into a functional product showcase space. The series covers practical acoustic treatment techniques including bass traps, absorption versus diffusion panels, subwoofer placement, rear channel configuration, and floor and ceiling treatment. Listeners dealing with difficult room acoustics will find actionable guidance on the specific challenges that affect low-frequency response and overall sound quality.
This roundup covers wireless headphone options for home theater use, spanning RF models operating on 900 MHz and 926 MHz bands to digital systems using 2.4-2.8 GHz KLEER lossless transmission and the Sony MDR-DS7500's 2 GHz spectrum with Dolby TrueHD and 7.1Ch decoding via HDMI inputs. Frequency range, battery life, and transmission distance vary significantly across the five featured models, from the budget JVC HAW600RF at $54 with a 164-foot range to the Sony MDR-DS7500 at $429 with a 5 Hz to 25 kHz dynamic reproduction range. Readers balancing audio quality against household disruption will find practical guidance on matching price points and wireless protocols to real-world home theater constraints.
A 2013 AV receiver buying guide covers six models across three price tiers, from the Sony STR-DH740 at $275 with 4K pass-through and four HDMI inputs to the Sony STR-DA5800ES at $2100 featuring nine HDMI inputs, a four-port Ethernet switch, and Control4 automation support. Mid-tier standouts include the Yamaha RX-A2020 with YPAO Reflected Sound Control and the Denon AVR-X3000 with Audyssey Gold calibration and seven HDMI inputs. Readers can use the tiered breakdown to match receiver capability to budget and speaker investment, avoiding overspending on processing that outpaces their speaker system.
Subwoofer selection, placement, and calibration fundamentals are covered in this home theater primer, with room-size guidelines ranging from a 10-inch driver for spaces under 1,200 cubic feet up to a 16-inch driver for rooms exceeding 5,000 cubic feet. Key setup parameters include crossover frequency (80Hz typical for floor-standing speakers, up to 120Hz for small speakers), phase adjustment, and Variable Tuning Frequency port configuration for balancing bass extension against headroom. Practical guidance on the subwoofer crawl technique and auto-calibration best practices helps readers achieve optimal low-frequency performance without expensive cables or complex acoustic theory.
Speaker sensitivity, measured in decibels at 1 meter with a standard test signal, is a key efficiency metric where scores above 90 dB are considered excellent and indicate less strain on your receiver or amplifier. Impedance, typically rated at 8 ohms, determines how much load a speaker places on an amplifier, and connecting two speakers in parallel halves that impedance to 4 ohms, which can damage underpowered receivers. Understanding these specs alongside frequency response and power handling helps buyers make more informed decisions without relying solely on listening tests.
The Cerwin Vega VE series bookshelf (VE 5M) and center channel (VE 5C) speakers offer a budget-friendly 5.1 bedroom surround setup, with both models rated down to 60 Hz and sensitivity figures of 89 dB and 91 dB respectively, making them easy to drive with a modest receiver. At $129 per pair for bookshelves and $99 for the center channel, the speakers delivered crisp highs and surprisingly full bass for their compact cabinet size, though a subwoofer is recommended for bass-heavy content. For anyone repurposing spare AV equipment or building a first 5.1 system in a smaller room, these separates offer a practical advantage over bundled home theater in a box alternatives.
Five AV receivers under $600 are ranked by feature-to-price ratio, with the Denon AVR-2313CI taking the top spot for its FLAC HD audio support, AirPlay integration, and 4K upscaling capability. The Onkyo TX-NR626 stands out for its Audyssey MultEQ room correction and Qdeo video processing, while the Sony STR-DN1040 leads on raw power at 165W per channel. Buyers prioritizing network audio, multi-room control via iOS/Android apps, and 4K-ready video processing will find strong options across all five picks without exceeding a modest budget.
The Denon AVR-2313CI 7.2 receiver delivers seven discrete 105-watt channels with Audyssey MultEQ XT room calibration, AirPlay, and full IP/RS-232 control for home automation integration, while the HSU Research VTF-3 MK4 subwoofer - a 74-pound cabinet capable of reproducing tones down to 16Hz - rounds out a compelling home theater pairing under $1,300 combined. The MK4's dual removable foam port plugs and EQ mode switching allow tuning for room size and output preference, making it adaptable for real-world setups. Both products offer strong performance-to-price ratios that home theater enthusiasts at the mid-tier budget level will find worth investigating.
The Pioneer VSX-70 is a 7.2-channel AV receiver priced at $750 MSRP, delivering 90 watts per channel (20Hz-20kHz, THD 0.08% at 8 ohms) across 7 discrete amplifiers with 8 HDMI inputs including MHL 2.0 support. Audio performance impressed across 256Kbps AAC, Blu-ray, and lossless formats, though the auto-calibration required manual subwoofer gain adjustment via the iControlAV2013 app. Buyers who want AirPlay, DLNA, Pandora integration, 4K scaling, and 3-zone output in a single mid-range unit will find the VSX-70 a capable and expandable choice.
Digital Room Correction (DRC), powered by Digital Signal Processing (DSP), addresses acoustic problems caused by room modes (standing waves) that amplify or cancel specific frequencies at your listening position, regardless of equipment quality. Systems like Audyssey use a calibration microphone to play test tones through each speaker, measure frequency response, and apply a custom EQ profile in a process taking five to twenty-five minutes. For home theater owners whose expensive gear underperforms, running DRC before investing further in equipment or acoustic treatments is a practical and low-cost first step.
Magic Mike arrives on Blu-ray with a Warner 1080p/AVC-encoded transfer shot on Red Epic cameras, faithfully reproducing Steven Soderbergh's deliberately skewed, near-monochromatic color palette with well-resolved textures and crisp edges. The DTS-HD Master Audio 5.1 surround track is the disc's standout, delivering pulsing low-end, aggressive rear-channel support, and eerily realistic directionality during the club sequences. Viewers seeking a technically capable Blu-ray with strong audio performance will find this release rewarding, even if the intentionally muted video presentation limits outright demo-disc appeal.
The Campaign arrives on Blu-ray with a 1080p/AVC-encoded transfer delivering clean edge definition, deep black levels, and fine detail resolution down to individual facial textures. The DTS-HD Master Audio 5.1 surround track handles the front-heavy mix competently, with solid LFE output and clear dialogue, though immersive rear-channel activity is limited to crowd-heavy scenes. Buyers seeking a raucous R-rated comedy with reliable A/V performance will find this disc a worthwhile pickup, even if the film itself ranks as mid-tier in the genre.
A 7.1 surround sound system adds two rear surround speakers positioned 135 to 150 degrees behind the listener, building on the 5.1 configuration that traces its roots to Dolby AC3 and DTS discrete formats from the early 1990s. Lossless 7.1 formats including Dolby TrueHD and DTS Master Audio were developed for home use in 2005 and 2006 respectively, yet theatrical 7.1 content remains limited. Upgrading makes practical sense only if your room allows proper rear speaker placement and you regularly watch 7.1 Blu-ray titles; otherwise, investing in a better 5.1 system delivers more value.
