Description
Product Overview
The Acme Speaker Port Tube is a precision‑engineered component designed to improve the bass response of vented speaker enclosures. Constructed from high‑impact ABS plastic, the tube offers durability and resistance to heat and moisture. Each tube measures 100 mm (4 in) in total length with a 39 mm (1.5 in) opening diameter and a maximum outer diameter of 61 mm (2.4 in), providing a versatile fit for a wide range of speaker cabinets. The sleek black finish not only looks professional but also helps conceal the port within most enclosure designs. Packaged in sets of eight, these tubes are ready for immediate installation.
Usage
Designed for both hobbyist and professional audio builders, the Acme port tube excels in home theater systems, car audio upgrades, and custom bookshelf speakers. Its low‑turbulence design minimizes unwanted noise, making it ideal for high‑fidelity listening environments, gaming rigs, and studio monitoring setups. The standard mount holes simplify installation, allowing users to secure the tube quickly without additional drilling or modifications. Whether you are retrofitting an existing cabinet or constructing a new vented box, this tube delivers consistent performance across a variety of acoustic applications.

FAQ
What size speaker enclosure is this port tube compatible with?
The tube is designed for enclosures that use a 1.5 in (39 mm) port opening. It works well with cabinets ranging from small bookshelf speakers to larger floor‑standing models, provided the internal volume is tuned for a 4 in port.
Can I adjust the length of the port for different tuning frequencies?
The tube comes in a fixed 100 mm length, which is ideal for many standard designs. For custom tuning, you can combine multiple tubes or use extension pieces, but ensure the total length matches the desired resonant frequency.
Is the ABS material safe for high‑power speakers?
Yes, ABS plastic tolerates the heat generated by high‑power drivers and maintains its shape without warping, ensuring consistent acoustic performance over time.
Do I need additional hardware to install the tube?
No additional hardware is required. The tube includes pre‑drilled mounting holes that align with standard speaker cabinet mounting patterns, allowing you to secure it with screws or bolts you already have.
How does this tube reduce turbulence compared to regular ports?
The internal geometry of the Acme tube features smooth, rounded edges at both the entrance and exit, which streamlines airflow and minimizes vortex formation. This design reduces chuffing noises and preserves the purity of the low‑frequency output.
