The Challenge
A few years ago, we set out to find speakers that could truly recreate the sound of a commercial theater. However, the DIY and commercial options were either too large for us or too expensive. We wanted speakers with the same punch but in a compact form that could fit typical home spaces, using horn-loaded compression drivers for the efficiency and clarity that define a cinema-like experience.
That journey led to the development of the LCR10, but from the beginning, we knew a full system would require more than just great front stage speakers. To preserve proper timbre matching and seamless panning, we needed surround speakers built on the same design principles.
The Solution
The SUR08 was created to complete the system. It brings the same design principles as the LCR10 into a more compact, but still high-performance surround speaker, perfectly voiced to match, with the output and clarity to deliver convincing effects at cinematic levels in a smaller package.
We designed the SUR08 speaker guide to be just as simple and accessible as building our LCR10s—empowering anyone, from first-time builders to seasoned DIYers, to construct high-performance surround speakers that match their front stage in both sound and intent. Our goal is to help you build a fully immersive cinema system that fits your space, your budget, and your creative vision.
We’re thrilled with how the SUR08 completes the lineup. We’ve integrated these surrounds into our own theaters and tested them extensively with the LCR10 to ensure seamless panning and consistent voicing. We hope you enjoy building and listening to these speakers as much as we enjoyed designing them!
Comprehensive SUR08 Speaker Building Guide
- 47 pages of design, prep and assembly with clear pictures to show you what to do.
- You can build a speaker even if you have never attempted to do so before.
Seamless LCR Integration
- Uses the same horn, compression driver, and woofer family as the LCR10 for flawless front-to-back cohesion.
- Create a cinematic soundstage where effects glide seamlessly across every channel—just like in commercial theaters.
LCR or Surround—You Choose
- Designed as a surround, but powerful enough to run as an LCR in smaller rooms or tight installations.
- Perfect for baffle walls, wide channels, or height layers where space is tight but performance can’t be compromised.
Big Performance. Smaller Package.
- 92dB sensitivity and 250W RMS handling
- Clean extension down to 70Hz on-wall means full-range sound and no distortion, all in a smaller design.
Fully Dimensional Drawing Package Included
- Full Dimensioned Drawings for Cutting the MDF or Plywood panels Manually
- DXF Files for CNC cutting included for both 18mm (.708″) and 19mm (.75″) material

Comprehensive Guide for building the SUR08 Speaker
- Size (WxDxH):
- 37.5cm x 22cm x 43cm (WxDxH)
- Frequency Response (+/- 3dB)
- 70Hz to 18kHz
- The B&C DE250 compression driver has an F3 of 18Khz. Since most people over the age of 20 cannot hear over this, we don’t think this is an issue. However, the B&C DE250 has an incredibly smooth and detailed sound across its whole frequency range that is not fatiguing for longer listening sessions – such as 2-3 hour movies at loud volumes – and is considered one of the best compression drivers because of this.
- Directivity: 90H X 40V
- Recommended crossover: 80Hz or lower depending on the room
- MUST BE USED WITH ROOM EQ – since we are using an off-the-shelf crossover, room EQ is a requirement.
- Cost of Build: 1 SUR08 would cost around USD 400 to build
*Graphs do not indicate sensitivity of speaker as currently we do not have a method to control 1W from our amps.
**All data collected was measured using a quasi-anechoic measurement method
What’s In the Book?
- Complete CNC and Manual Drawings for cutting the wood panels: you can either have the speakers cut out by a CNC shop or create them manually with the tools you have at home.
- Complete list of materials and tools required to create the speakers
- Step by step guide on how to cut, assemble and connect the speakers up
- Detailed discussion on design principles and performance characteristics of the speaker including power requirements and expected behavior at listening distances from 3m to 5m including the required power to hit reference levels
