Desktop Miniature Nautilus HiFi Speaker with Bass Reflex Design (3-inch Elegant Full-Range Driver + Bowers & Wilkins Titanium Dome Tweeter Compensation)

First, I would like to pay tribute to Laurence Dickie, the primary designer of the Nautilus speaker. This is something I’ve been researching since 2019, and I’ve always wanted to make a miniature version of the Nautilus speaker to sit on my desk. However, because the first printer I used did not produce satisfactory results, the design was put on hold. Now, with the Bambu printer, I’ve optimized and printed it. All materials are made of PETG Eco. In the video, besides painting the place where the speaker connects to the base black and removing supports, no sanding was done. The actual speaker should be sanded to look better.
The speaker size is designed based on the travel of the P1S printer. The first version of the blueprint is best suited for 3-4 inch speakers with an outer diameter of 117mm or less. In terms of appearance alone, the most similar to the original should be the 4-inch ceramic aluminum basin from Guan Yin, but based on the volume requirements, a 3-inch speaker is more suitable. Therefore, I ultimately chose a 3-inch speaker, the renowned elegant 3-inch white basin speaker that ranks among the best in terms of low-frequency performance. The actual appearance is also quite good, and the sound quality exceeds expectations. The tweeter uses a B&W small titanium diaphragm that was disassembled from a high-end Philips TV (both small tweeters in the document can be used).
Here is a simple production and audition video, 1p vertical production video. 2p horizontal simple audition, recorded with a mobile phone, connected to a 3D printed small amplifier made in 2021. The printed parts have only been removed from the support and not sanded, nor sealed, nor connected to a crossover. The tweeter is only connected in series with a 4.7uf capacitor, and the woofer is directly connected.
