Project Description:
Speakers were built from foamcore with a 58″ Fibonacci spiral transmission line in a 12x9x7.5″ curved box covered in Mozambique veneer based on a design found on diyAudio by xrk971 They are progressively stuffed with polyfill.

Design Goals:
I was intrigued by the unique design and use of the unusual building material, as well as the quality sounds derived from inexpensive speakers. I was not prepared for the sound these speakers produced. They have a strong bass response to 45 Hz, and test down to 20 Hz. Total cost, minus shipping, was $16.00, plus the $2.85 for the foamcore and $16 for the veneer.

Driver Selection:
269-609 6.5″ poly cone woofer 4 ohm
292-438 mylar tweeter 4 ohm

Enclosure Design:
Nautaloss I design 58″ Fibonacci spiral infinite baffle transmission line copied from diyAudio from a design by xrk971. https://www.diyaudio.com/forums/full-range/247598-nautaloss-ref-monitor.html

Enclosure Assembly:
12x9x7.5″ 3/16″ foamcore covered with 1/42″ Mozambique wood veneer

Crossover Design:
3.3 uf cap (027-328) and 1/2 amp polyswitch speaker protector (071-251) in series with the tweeter; .2mh inductor in series with the woofer on a modified speaker plate (269-011).

Tips & Tricks:
Go to diyAudio and the foamcore thread for plans. xrk971 is the guru for this, and for all foamcore enclosures. He recommends a combination of white glue and hot glue for assembly, and that works very well. Scoring the interior of the curve through the paper with a sharp razor knife aids making the spiral immeasurably, too, without creasing the outside, ruining its look. I didn’t see that step before I started, so I used spackling to build up the body to cover the bumps of the creases I made , which worked well, but made for an splotchy finish, hence the veneer. The original speaker called for is a 3.5″ full-range driver, the Tymphany TC9FD (264-1062 for 8 ohm, back order, or 264-1358 for 4 ohm), and the original width is 5.5″.

Conclusion:
The speakers were easy but a bit time-consuming to build, as they were my first such project, and I was modifying the original plans to compensate for a larger size speaker and adding a tweeter, because the original plans called for a full-range speaker and I had already bought the ones I used. The veneer added a lot to the looks, but doubled the cost of the project. I was very pleasantly surprised by the quality of sound from these speakers. The bass is outstanding, and the mids and highs are very natural. I can listen a long time with no fatigue.

About the Designer:
I am not the original designer. He is xrk971, on diyAudio, out of metro DC. He is a genius with foamcore, and has made several other foamcore designs, another of which I have also copied, with great success. I am a 75 year-old former F-15 mechanic who now hears jet-engine-sound tinnitus instead of the upper frequencies from my stereo, who loves to tinker and so made these as my second ever speakers.

Project Description:
Project began as a simple replacement of a blown bass speaker in a commercial bluetooth speaker (Doss Soundbox).

But then I decided to also replace the other drivers while I was at it. Figured I couldn’t get anything to match the case perfectly, so I decided to make a new case, a BT speaker has been something I’ve wanted to make a long time.

But then I also decided I didn’t care for the controls of the amp, and I wanted to add wifi capability, so I replaced the amp, preamp, controls, and power system as well.

In the end, the only parts remaining from the original speaker are the screws the hold the 2″ drivers to the soundboard.

I was in the middle of another project in the shop, but no music was an emergency that had to be fixed asap.

Design Goals:
I use a small portable speaker a lot; when working from home, when in my shop, when working out, and for dance parties with the kids.

Of course the goal of any speaker project is to look and sound as good as possible within the confines of the budget.

The speaker I was replacing took care of the conceptual design (the piecemeal on the fly design approach ensured it). 2.1 system with 2x 2″ 4 ohm speakers and a 1x 3.5″ 4 ohm speaker and 2x passive radiators.

I really wanted it to have wifi in addition to bluetooth so that there was no single controlling device that had to be nearby and dedicate its audio to it (mainly so I can watch ads while gaming or videos on social media without interrupting the music).

I have a retromodern design aesthetic.

Driver Selection:
1x Peerless SLS-85S25CP04-04 (# 264-1600)
2x Dayton Audio DMA58-4 (# 295-582)
2x Dayton Audio DMA80-PR (# 295-595)

Enclosure Design:
The basic scale is the same as the Soundbox I was replacing with the exception of depth. I moved the passive radiators to the sides and used speaker type passives instead of an oval rubber pad, which doubled the depth needed. Being wood and not plastic, its a good bit thicker.

I used stack laminated baltic birch (strips from some 3/4″ reclaimed pieces I have) and 3/8″ baltic birch sheet. The front and back are from a knarly old cherry board I found at an estate sale, cut quartersawn its figure is fantastic, and the color is so much richer than typical cherry.

The controls area is made from quartersawn figured maple “veneer” (about 1/4″ thick resawn) with a slim cherry border. The back was done similar, though a bit thicker, 5/16″ or so. Quartersawn wood moves much less than other cuts, important for the back to prevent bowing. I applied it bookmatched.

Shaping was done with my carving weapon of choice; angle grider with a flap disk.

Enclosure Assembly:
Lots and lots of Titebond 3. Lots. Huge amounts. Soundboard is screwed down.

Crossover Design:
Channel levels on the 2.1 amp for balancing; it has a built in low pass on the 0.1, not sure exactly what frequency.

Tips & Tricks:
Stack laminated baltic birch is almost as hard as an end grain maple cutting board and power carves excellent (its so hard its quite forgiving). I’ve used it on several projects now (I got a bunch reclaimed from Jaguar car crates years ago.

Ground loop isolator is VERY important to eliminate noise. I had massive hum problems until I added it, noise is minimal now.

Conclusion:
This thing sounds amazing. I added a bit more weight to the radiators, it can really hit low notes for a speaker this size.

Great project. Such a joy to work on and now use.

Design Goals:
I wanted something that sounded good and didn’t take up a lot of space. I somewhat used the “Hit maker” specs for a guide.

Driver Selection:
I could only use a 5″ due to space limitations.

Enclosure Design:
Solid black walnut, with top grain leather on the front and Alcantara type material on the back. 22″ hairpin legs. Approximately 44″w x 12″d x 8″h.

Tips & Tricks:
Take the wood to a cabinet shop for drum sanding in order to true it up. I had do deal with some warpage that complicated things, hence the custom tinted verathane.
Also, thin your verathane. It works much better on flat surfaces

Enclosure Assembly:
I made the enclosure in phenolic chipboard with double wall to leave the thickness of 3 cm with acoustic foam inside, with a reflex port on the front side. The finishes were given with Oak veneer and catalyzed semi-matt lacquer and black ink for the front.

Crossover Design:
I used a vintage crossover from late 70’s speakers with very good quality components. Use a Dayton L-pad to tune the midrange more precisely.

Enclosure Assembly:
I used a block plane to smooth the joints. After sanding, I did two coats of spray poly to seal the box, then used Rust-oleum 2x Ultra Cover Utlra Matte Black spray paint. Sand in between poly layers with an orbital sander, and use steel wool between dried layers of the spray paint to ensure the finish is smooth with no swirls or imperfections.

Tips & Tricks:
If you have a 3d printer, you can print the speaker grill components in PLA+ or most other tougher materials. I have uploaded them to Thingiverse and they are free to download. Will post links soon, but they can be found by searching “Blast Box”.

Conclusion:
This was a very fun project. It was partially inspired from some other builds on here, but I added some of my own twists. I designed the speaker grills for the 3-inch drivers, the subwoofer, and passive radiator. I searched forever to find the best options, but nothing seemed to fit as well as I’d like, so I designed my own speaker grills that can be 3d printed.

Project Description:
Self-powered line-source array.

Design Goals:
Concept was to create a simple but nice sounding speaker using budget drivers that I spotted in P-E’s “factory buyout” section.

Driver Selection:
YDT0420-4BP full-range 16-ohm (described as flat-screen television drivers).

Enclosure Design:
Open-baffle

Enclosure Assembly:
Stained poplar with tilt-angle adjustable wood/metal stands. Each speaker is 6 ft tall, 8” wide.

Crossover Design:
None; drivers operating in unison as full-range. As such, here’s the wiring scheme: Each speaker has two “groups” of four 16-ohm drivers, each group wired in parallel, resulting in a 4-ohm load per group. The stereo amplifier connection is one channel per group, and each speaker’s amplifier is driven in mono (via left and right channels respectively from the source). Clean & simple.

Conclusion:
Surprisingly full sound with an open & spacious sound stage, nice detail with an overall smooth presentation. Lower-end response is also respectable on their own given the driver specs, though the addition of a powered sub rounds thing out nicely.

About the Designer:
Retired engineer who’s been into fine audio equipment for many decades, like having fun with class-A amplifier builds and unconventional speaker designs.

Project Description:
This is a passive subwoofer made using the GRS 8SW-4 80W, 8″ subwoofer driver.

The finish is piano black.

Design Goals:
The goal of this project was to create a basic subwoofer with a piano black finish.

Driver Selection:
The driver is GRS 8SW-4 80W, 8″ driver,
Parts Express #292-480

Enclosure Design:
This is a sealed enclosure, 26″W x 16 1/2″H x 9 1/2″D

Enclosure Assembly:
The enclosure is made from 5/8″ particle board.

The finish is accomplished by first sanding the surface and using wood filler to fill any joints or rough spots.

Prime it with at least two coats, and sand the prime.

Spray at least 2-3 coats of gloss black. Sand and polish.

Spray at least 2-3 coats of clear gloss. After spraying the second or third coat, sand with 1000, 2000, 2500 grit sandpaper. Polish with liquid scratch and swirl remover. Do this for every additional coat of clear gloss.

Finally, go over the whole surface with wax and buff with a lint-free cotton cloth.

Tips & Tricks:
Always get the surface as perfect as possible before priming. Use wood filler on all joints between boards, and the ends of the particle boards.

Be very careful when spraying the first layer of clear gloss on the paint. Too much can cause the paint to crack and peel.

Always spray on horizontal surfaces.

Conclusion:
This was the biggest project of its kind I have yet attempted. I made a few mistakes with the finish, but the final product is still very satisfying, and sounds great. It plays classical, sacred, and country music exceptionally well. It’s also great for movies and video games.

The 80W driver is plenty powerful for any large to medium room. Right now, I’m powering it with a small Class D 2.1 amp, SKU: 320-608, but I will probably get a much more powerful one in the future.

This is fairly simple and inexpensive project for anyone who wants to try their hand at building their own hifi system.

Project Description:
After building the C-Note and Classix II kits, both of which are great speakers and phenomenal value, I wanted to explore a more HiFi kit. I spent quite some time considering various kits from GR Research, DIY Soundgroup and CSS Audio, among others. The Amigas rose to the top with the best overall value especially with cabinets included. Additional consideration was that they were compact towers that wouldn’t require stands. The lower sensitivity was a concern, however my Yamaha R-N303 would be strong enough to drive them in my average size master bedroom.

Design Goals:
Great HiFi sound on a budget

Kit:
Peerless by Tymphany DX25TG59-04 1″ Fabric Dome Tweeter

Enclosure Design:
Vented kit

Enclosure Assembly:
The kit arrived quickly and well packed. The quality MDF is significantly better than what you can get at your local hardware store. It went together beautifully, gluing everything except the baffle together at the same time. You will need a lot of 12”+ clamps if you do it this way. I highly recommend leaving the baffle off to line with dampening, secure wire leads and crossover. Anxious to hear these, I went with a simple furniture paint for finish – Valspar Chimney Smoke. Definitely worth the extra $ to buy the complete kits.

Crossover Design:
Thanks Paul! I used the PC boards for the crossover to which I highly recommend (eBay).

Tips & Tricks:
I highly recommend leaving the baffle off to line with dampening, secure wire leads and crossover. Predrill all your holes first to keep you cabinets debris free. I followed the designers recommendation to put some poly in the bottom 1/4 of cabinet. Cover your openings for sanding and painting to keep it clean inside. MDF can require a lot paint coats so you may want to use Kiltz primer first. I did this with my last project and it was night and day difference on how the paint laid.

Conclusion:
No regrets. These are an amazing value and I would absolutely do it again. The positive bass comments are true, big and tight, and you can feel it! These speakers are articulate but not fatiguing. Well placed in a medium size room they will wow you with soundstage and detail. They will not play real loud (max out under 100db) but do they sound great.
