Introduction

In Episode 485 of Home Theater Geeks, host Scott Wilkinson delves into the intricacies of creating a compact yet fully functional home theater, aptly named the "Hobbit Theater." This episode showcases a remarkable project by David Chu, who transformed a modest 10ft by 10ft room in his Vancouver duplex into a sophisticated home theater setup. Scott provides a comprehensive overview of the design decisions, technical specifications, and challenges encountered during the transformation.

Floor Plan and Room Dimensions

Scott begins by illustrating the unique floor plan of David's home theater. Despite the room's square dimensions, its diagonal entryway introduces an unconventional layout:

"It's a very oddly shaped area. I mean, it's mostly square, but it's got that diagonal sort of entryway open to the office area." (05:15)

David initially considered placing the screen on the shorter wall opposite the angled entry but opted to rotate the orientation by 90 degrees, a decision Scott endorses:

"David decided it just felt right to flip the orientation by 90 degrees and I have to agree with him." (09:22)

Screen and Projector Setup

Maximizing the screen size within the limited throw distance of 9ft 8 inches was paramount. David chose the Elite Lunette Cinewide, a 106-inch wide, 2.35:1 slightly curved screen. The curvature aids in minimizing pin cushioning, a common distortion at the screen's edges:

"The slight curvature in the screen helps reduce what's called pin cushioning." (12:40)

David also incorporated an anamorphic lens from Panamorph, the Cine Vista, priced around $1,000. This lens allows the projector to maintain a constant image height (CIH) across various aspect ratios, ensuring a consistent viewing experience:

"With the Panamorph lens, the projector can do constant image height, which changes the width of the image without altering the height." (18:05)

Acoustic Treatment

Given the room's proximity to the back wall, acoustic treatment was crucial to manage bass buildup. David employed multiple strategies:

• Super Chunk Wool Bass Traps: Positioned in surround pilasters to absorb low-frequency sounds.
• Fiberglass Base Traps: Installed in the rear soffit and beneath the screen to tackle significant bass energy.
• Roxul Comfort Board: Applied to walls for additional sound absorption, comparable to materials used in professional recording studios.

Scott highlights David’s commitment to acoustic isolation to prevent sound leakage into the duplex:

"David installed another layer of 5/8 inch sheetrock with green glue to isolate the sound and prevent it from transmitting to the other half of the duplex." (25:30)

Speaker Placement

Optimizing speaker placement within the confined space was challenging. David mounted the main front, center, left, and right speakers above the screen using Paradigm Mini Monitor LCRs, directing them downward toward the seating area:

"The speakers are mounted above the screen, pointing down towards the seating position. It's not ideal, but given the constraints, it's the best solution." (30:12)

Due to limited space behind the screen, rear surrounds weren't feasible. Instead, Paradigm Atom Monitors were utilized for the left and right surrounds, maintaining a 5.1 system setup.

Equipment Rack and Hidden Features

One of David's standout features is the hidden equipment rack within a closet adjacent to the subwoofer niche. Accessories include:

• SVS SB12 Subwoofer: Custom-fit into a niche for optimal bass performance.
• Fabric-Covered Equipment Door: Maintains the room’s aesthetic by concealing technical components.

Scott commends the ingenuity behind the hidden rack:

"I spent an inordinate amount of time figuring out how to make the equipment rack door completely hidden. But he worked. It works. Beautiful job there." (35:45)

DIY Aspects and Costs

David undertook the project himself, significantly reducing costs. The overall expenditure was approximately $12,000, evenly split between equipment and building materials. Reusing furniture and existing equipment from a previous theater further economized the budget:

"The active planning phase took about three months and construction took another four months at a total cost of only $12,000." (40:10)

Scott encourages DIY enthusiasts, noting the personal satisfaction and cost savings of self-installation:

"If you want to save money and you're handy, doing it yourself can really save a lot of money and be very satisfying at the same time." (42:30)

Technological Upgrades Since 2013

Reflecting on the original setup from 2013, Scott speculates on potential upgrades David might have implemented over the past decade:

• Audio Enhancements: Upgrading to Dolby Atmos and adding overhead speakers.
• Visual Improvements: Transitioning to a 4K projector for higher resolution and better image quality.
• Modern Sources: Incorporating current gaming consoles, streaming devices, and advanced media players.

Despite technological advancements, the core design and acoustic treatments established by David remain effective and adaptable:

"The fundamentals of the room didn't change, and I think he treated those extremely well. So now hopefully he has atmos, he's got some speakers overhead, he's got a 4K projector. But the room is the room and the room is great." (48:50)

Conclusion

Scott Wilkinson wraps up the episode by applauding David Chu’s exceptional work in transforming a small space into a high-quality home theater. The blend of thoughtful design, effective acoustic treatment, and strategic equipment placement serves as an inspiring blueprint for enthusiasts with limited space.
