Step 1
Choose your enclosure style
Every style is CNC cut from 3/4" birch to your size. Pick one to open the 3D designer.
Or start from a ready-made build
Pick the kind of speaker you are building. It opens in the 3D designer with sensible sizes, driver holes and braces that you can change freely. Check your driver's mounting drawing before you order.
How big should my speaker holes be?
Size the front panel from your driver, not from its nominal size. The cutout is usually smaller than the driver's frame so the frame sits on the baffle. These are typical starting points only. Always confirm with the mounting drawing from the driver's maker, then enter the exact hole size in the designer. Round, oval, square and rectangular holes are all available.
This tool lays out and cuts the box. It is a build layout, not an acoustic design, so choose the volume, port size and crossover from your driver's specifications. Drivers, wiring and finishing are not included.
| Driver | Typical cutout |
|---|---|
| 1" dome tweeter | 2" |
| 3" full-range | 2.6" |
| 4" woofer / midrange | 3.5" |
| 5.25" woofer | 4.5" |
| 6.5" woofer | 5.6" |
| 8" woofer | 7.1" |
| 10" subwoofer | 9" |
| 12" subwoofer | 11" |
| 15" subwoofer | 13.9" |
Custom speaker enclosures, CNC cut to your exact size
Build the speaker cabinet you actually want. Design a custom tower speaker box in 3D, choose its exact width, depth and height up to 72 inches, add driver and port cutouts, and brace it with internal ribs. We CNC cut every part from 3/4 inch raw birch and ship across the USA and Canada. Ideal for DIY speaker builders, audiophiles, home theatre installers and custom audio shops.
Why build your speaker box with us
3D design tool
Set your own width, depth and height up to 72 inches and spin the enclosure a full 360 degrees. Drag cutouts into position.
Four cutout shapes
Round driver holes, square and rectangular ports, and triangular cutouts on any face of the cabinet.
Internal ribs and cutout ribs
Add bracing at any height in 1/2 inch or 3/4 inch material, with an optional round cutout for airflow.
Precision CNC cutting
Every panel and opening is machined to your exact dimensions from 3/4 inch raw birch for tight, repeatable joints.
Instant transparent pricing
$225 base at 12 inches tall plus $50 per extra 10 inches of height, with cutouts and ribs itemized.
Shipped across North America
Order online and receive CNC cut enclosure parts anywhere in the USA and Canada.
Speaker cabinet CNC machining capabilities
Speaker baffles, driver openings and ports need accurate dimensions and clean edges. CNC routing delivers repeatable precision that hand tools cannot match.
Speaker hole cutting
Accurate round openings for woofers, midranges, tweeters and subwoofer drivers.
Port and vent machining
Rectangular and square openings for bass reflex ports and ventilation.
Internal bracing
Plain and cutout ribs in 1/2 or 3/4 inch to stiffen tall towers and large panels.
Clean edges and tight joints
CNC accuracy means panels fit square, so assembly is faster and seams are tighter.
Birch plywood: a better speaker cabinet material
Raw 3/4 inch birch plywood is rigid, strong and has a tight, void-free core, which helps control cabinet resonance. It machines cleanly, glues well and finishes beautifully with stain, paint, oil or veneer, so it suits both hi-fi cabinets and rugged pro audio builds.

Speaker enclosure questions
What material are the custom speaker enclosures made from?
Standard enclosures are CNC cut from 3/4 inch raw birch plywood, a dense, stable, void-free panel that takes stain, paint or veneer well. You can also pick another exterior from our panel goods, such as MDF, veneered panels, melamine or HPL, right in the builder.
How do I choose the hole size for my speaker driver?
Use the cutout diameter from your driver maker's mounting drawing. As a rough guide a 6.5 inch woofer needs about a 5.6 inch hole and a 1 inch tweeter about 2 inches. Enter the exact size in the designer and the 3D view shows the fit.
Is this an acoustic design for my speaker?
No. The builder lays out and cuts the box, including driver holes, ports and braces. Internal volume, port tuning and crossover come from your driver specifications. Drivers, wiring and finishing are not included.
Can I start from a ready-made speaker design?
Yes. Choose a starting build such as a desk or Bluetooth speaker, bookshelf speaker, tower, subwoofer cube, octagon or triangle tower, then change any size, hole or brace. You can also describe your speaker to the AI designer and it will build it for you.
How tall can a tower speaker enclosure be?
Tower enclosures can be built up to 72 inches tall. You choose the exact width, depth and height in the 3D builder and the price updates instantly.
How much does a custom speaker enclosure cost?
Pricing starts at $225 for a 12 by 18 by 12 inch enclosure and adds $50 for each additional 10 inches of height. Cutouts and internal ribs are priced separately and shown before you order.
What cutout shapes are available?
You can add round, oval, square, rectangular and triangular cutouts on the front, back or either side, and position each one visually in the 3D preview or by exact measurements.
Can you cut speaker baffles, driver holes and port openings?
Yes. Round driver openings, rectangular and square port or vent cutouts and triangular openings are CNC machined to your measurements, so drivers and ports fit cleanly.
What are internal ribs and internal cutout ribs?
Internal ribs are braces that stiffen the cabinet and reduce panel resonance. Internal cutout ribs are braces with a round opening so air and wiring can pass through. Both are available in 1/2 inch or 3/4 inch material.
Do I get a finished, assembled speaker cabinet?
You receive precision CNC cut birch parts sized to your design, ready for you to glue, assemble, sand and finish with stain, paint or veneer.
Do you ship speaker enclosures to the USA and Canada?
Yes. Enclosures are CNC cut to size and shipped across the USA and Canada, or available for pickup.
Is this suitable for subwoofer boxes and studio or hi-fi speakers?
Yes. Builders use the same tool for tower speakers, bookshelf cabinets, subwoofer boxes, studio monitors and custom hi-fi projects. Tell us about larger or repeat runs through the quote form.
