Spiral TQWT - 200cm Extreme Path [Deep Bass Edition]
Description:
This is a 3D-printable TQWT (Tapered Quarter Wave Tube) speaker enclosure featuring a unique spiral design. By winding a 200cm (approx. 6.5ft) acoustic path into a compact, organic form, it achieves a balance between space-saving design and genuine horn-loaded sound characteristics.
If you want a more compact setup, check out my 90cm Free Version (https://cults3d.com/en/3d-model/home/spiral-tqwt-enclosure-90cm-acoustic-path-edition-compact-high-efficiency) first!
Acoustic Characteristics:
Tuning Frequency: Approximately 50Hz. The enclosure resonance is precisely calibrated for a deep, rich, and powerful low-end response.
High Efficiency: Despite its extended path, this design offers impressive efficiency and high sensitivity. It delivers a clear, energetic sound even with low-power amplifiers, making it perfect for premium desktop or room setups.
Unique Geometry: The spiral structure minimizes internal standing waves while maximizing the effective path length within a minimal footprint—a feat only possible through 3D printing.
Specifications:
Total Path Length: 200cm
Enclosure Type: Spiral Tapered Quarter Wave Tube
Target Resonance: Tuned for deeper, richer bass (around 40-50Hz range depending on the driver).
Acoustic Benefit: The 2m path significantly extends the low-end performance, delivering the kind of scale and depth that only a long-folded horn can provide.
Recommended Driver: 2-inch Full Range Driver (AliExpress Link) (https://ja.aliexpress.com/item/1005007039421431.html)
Measured Performance:
I have actively measured the frequency response of this enclosure (as shown in the images).
Real-world Evidence: Unlike many untested models, this enclosure has been measured to ensure acoustic performance.
Smooth Response: It delivers a surprisingly flat and smooth response across the mid-to-high frequencies, providing clear vocals and excellent imaging.
Deep-End Extension: Thanks to the 2m TQWT spiral design, it maintains incredible energy right down into the deep bass region, punching well above what you would expect from its actual physical footprint.

Micro Double Bass Reflex Desktop Speaker - Deep Bass from 2" Driver
Premium Acoustics in a Compact Footprint
This is a highly optimized, high-fidelity Micro Double Bass Reflex Enclosure specifically designed for 2-inch full-range speaker drivers.
While typical small enclosures sacrifice low-end punch, this premium dual-chamber system achieves a balanced, deeply satisfying bass response and an incredibly smooth midrange—making it the ultimate DIY project for an audiophile desktop setup.
📐 Scientific & Meticulous Engineering
To extract the absolute maximum performance from a compact 2-inch driver, the internal structure features a precisely calculated 1:2 volume ratio between the twin acoustic chambers (Chamber 1 : Chamber 2).
This exact ratio ensures flawless acoustic coupling between the primary and secondary ports. It minimizes the notorious midrange "diops" or muddy peaks common in poorly tuned double-bass reflex designs, resulting in an exceptionally flat and predictable frequency response.
Furthermore, the elegant cylindrical exterior isn't just for aesthetics—it helps disperse internal standing waves, providing a distortion-free, natural listening experience even during near-field (close-up) desktop use.
📊 Measured Frequency Response (See Image)
Don't just take our word for it—the proof is in the data. As shown in our actual measurement graph (pink noise test):
Ultra-Flat Midrange (100Hz – 2kHz): The 1:2 chamber ratio works perfectly, delivering an incredibly linear and smooth mid-range. Vocals sound stunningly natural and lifelike.
Extended Low-End Performance: Outstanding acoustic damping allows the bass to remain flat down to 100Hz, with a resilient low-frequency energy tail extending gracefully down into the sub-bass region.
Fatigue-Free Highs: Crisp, beautifully balanced treble extension that guarantees comfortable, long-term listening sessions while working or relaxing.
🛠️ Smart "Screwless" Assembly
The enclosure features a brilliant 2-piece interlocking design. The speaker driver sits perfectly in the upper body and is clamped securely from behind using the custom-designed Driver Retaining Ring.
* No messy glue or ugly front-facing screws required.
* Easy to print, clean look, and rock-solid airtight seal.
🔋 Independent Wireless Desktop Audio
The upper enclosure body includes dedicated pre-modeled cutouts for a Type-C charging port and a hardware toggle switch, allowing you to seamlessly integrate a Bluetooth SoC module, battery pack, and amplifier IC to build a fully self-contained, high-end wireless stereo pair.
