This IKEA BLANDA MATT Bowl Speaker Hack Is Genius (Full DIY Breakdown)

David Kan is not any stranger to IKEA Hackers. This audiophile has delivered some amazingly intelligent concepts, like these speakers out of monitor stands and how you can create a sleek speaker support.
Today, we’re exhibiting off one other one in all his lovely designs, which, like a lot of his concepts, started with a query.
He considered how attractive the acoustics are in domed cathedrals, which made him query why the horn of a horn speaker all the time must be flared and curved outward. Couldn’t or not it’s dome-shaped to realize the identical heavenly sound?
These questions began whirring round his head as he checked out IKEA’s BLANDA bowls.
“I do know, I do know,” he laughed, “Most individuals would consider spherical audio system after they see the BLANDA bowls. I truly drafted a design for that.” (Of course, you probably did, David.) “But,” he continued, “I’ve already made two pairs of spherical audio system, one with plastic bowls and the opposite with chrome steel, so I didn’t need to repeat myself.”
Therefore, David mixed his bowl horn concept with one other challenge that’s been hanging out on his drafting board for some time, deciding to make the BLANDA bowl the star of the present.
Pull up David’s playlist to hear his Cremona Alfa speakers in motion; it’s the proper inspiration for making your individual.

How To Make Horn Speakers Using BLANDA Bowls
1. Draft Your Design

All nice hacks begin with a plan. David drafted his design utilizing Photoshop. This helps make changes and make sure dimensions.

2. Make the Panels

Map out the assorted panels on the suitable thicknesses of plywood utilizing the exact measurements out of your drafted design. Cut every panel out with a round noticed.
3. Create the Holes

Cut out the f-hole on the within panels utilizing the jigsaw. Polish the sides with sandpaper. Create the spherical holes on the entrance panels, making two for the 4” coaxial drivers and one for the three” bass driver.


Make the spherical gap on the rear panel for the three” bass driver, and minimize out yet another spherical gap on the decrease half for the speaker binding posts. Cut holes on the underside plinths for mounting the bass reflex tubes.
4. Prep the Coasters

Drill holes on the GROGGY (or related) coasters, and set up the speaker binding posts. Each coaster ought to have two pairs of posts for bi-wire or bi-amp.
Make certain to incorporate good insulation between the binding posts’ brass shafts and the chrome steel coaster. Drill 4 mounting holes into every coaster, one in every nook.

5. Make the Enclosure

Assemble the speaker enclosure by gluing the entire panels. Nail down the aspect panels, and clamp to dry.

Polish the enclosure with an influence sander and paint the cupboard with wooden stain. David suggests Winmax PolyShades satin honey pine, and he used three coats.

Drill holes into the BLANDA bowls and place the bowls on the motive force mounting holes to mark the mounting place. Connect the speaker cables to the drivers, permitting sufficient size for every pair of cables to string by means of the binding publish gap on the rear panel.

Secure the entire drivers with mounting screws. Connect the speaker cables to the bi-wire/bi-amp mounting posts, inserting one 4” coaxial 2-way driver parallel with one 3” subwoofer.

Interesting Tips and Insights from the Hacker

David used very low cost automobile speaker drivers for this challenge. However, in earlier designs and tasks, he’s used very high-quality German-made drivers. What he discovered was one thing that proved his long-held idea — “That the enclosure design is the only most crucial component in DIY audio system, extra essential than the drivers themselves.”

Therefore, that is undoubtedly one thing to bear in mind if you happen to determine to imitate this hack and need to maintain your finances in examine.
David notes how inserting the audio system side-by-side makes them seem like an oblong double bass.

The bowl horns actually enhanced the sound, making a wealthy, heat tone that you just wouldn’t usually get from a pair of tiny 4-inch drivers.
It’s “extra like listening to reside musical devices than hi-fi audio system,” David shares, persevering with, “These audio system should be honored with the title Cremona, the cradle of legendary string instrument makers like Stradivari and Amati.”
