designed by david d’imperio for OMA audio, the wooden conical horns are made from a choice of solid pennsylvania black walnut, cherry or ash.

Hello,Does anyone happen to have a copy of theFANE loudspeaker enclosure design and construction booklurking...

DS18 PRO-SDF6 6.5" Loudspeaker Horn Diffuser Horn - Black The PRO-SDF midrange diffuser innovated design was dreamed up and brought to life by the DS18 team. Its unique design allows music to be projected for miles and miles without affecting the quality of sound. This diffuser works best with our EXL line, but can also be used with any of our other midrange speakers.

Loudspeaker Design by Trial and Error: "Now I need to make my own pair of loudspeakers!" I thought, after finishing my Serious Amplifier. "And if I can make a decent amp, I can surely do this." So I jumped into the world of speaker design and building, expecting a nice clear path to a pa…

The broadcasts are in retaliation to Pyongyang’s denial of planting land mines in South Korea’s Demilitarized Zone which maimed two soldiers last week

The speaker building psychosis got the best of me again after becoming intrigued by the unique dipolar subwoofers patented by German speaker builder Axel Ridtahler. The name "RiPol" is short for "Ridtahler dipole". I will share my CAD drawings and parts lists of the version shown here (rounded edges) or a simpler version with exposed plywood edges-- just email me: [email protected] The woofers in a RiPol are in an opposing push/push configuration. A RiPol is basically a compact, folded-baffle dipole, except the radiation pattern is not the classic figure-8 dipole but cardioid shaped, with a pronounced frontal lobe. It can play very low <20Hz), and because the cardioid pattern nulls the off-axis output, it's less prone than conventional monopole subs to excite the room resonance which can give bass the dreaded “one-note boom”. Whereas a conventional sealed or ported box forces the woofer's resonance higher than it's resonance in free air, the resistance of the air masses within the Ripol's front chamber actually lowers the woofer's resonant frequency by as much as 10Hz (depending on chamber size, 7Hz is typical). The result is lower distortion and improved tonal quality because most music contains little or no energy that low, so the woofers' resonance is not excited. Ripoles pressurize the room differently than conventional subs. I would describe their sound as quality over quantity-- clean and unobtrusive, arising from nowhere and receding back to nowhere. Great for jazz-- not so much for HT sound effects. The Peerless SLS 12” woofers are ideal for RiPol use, and fairly inexpensive, but are no longer sold in the US. I recently (2022) purchased several from a company named "THLP" in France, and they arrived in about a week. I found no published modeling data for a Ripol so I based the dimensions on guidelines posted by a respected Ripol guru who goes by the user name "Rudolf" on the DIY Audio Forum, which I've paraphrased below: Area of front chamber opening should be 1/3 to 1/4 of woofers’ combined piston area (SD). For woofers having more than 10mm X-max, use 1/3 SD minimum. For woofers with 10mm or less X-max, chamber area can be 1/4 SD. Area of rear chamber opening should be 1/2 to 1 SD. Chamber depth need not be greater than necessary to fit the woofer. The front and rear chambers have rather chamber resonances which must be either avoided by setting the crossover frequency at least one octave lower below it, or by notching it out with a passive filter or parametric EQ. For the Ripol shown here; the front chamber resonance peaks at 299Hz and the rear chambers at 294Hz. I simply avoid exciting these resonances using a 70Hz crossover with a steep filter slope (24db or 48db / octave). The boxes are 3/4 red oak plywood, edge trimmed with quarter-round oak molding. The center C-section assembly glued up from solid white oak planks stained in a contrasting color for effect and indexed to the mating box halves with (4) 1/4 oak dowel pins on each side. The assembly is held together with 1/4-20 all-thread rods and cap nuts as shown in the photos. The woofer cutouts in the baffle boards are cut with a bit of extra clearance to allow the woofer magnets to center themselves in the holes in the outer panel. The holes in the outer panels allow .090" of clearance for the speaker magnets and I used foam speaker gasket tape to seal around the woofer magnets. The two 8-Ohm woofers are wired in parallel and in phase (push/push, not push/pull), for 4-Ohm load. Rabbit cut plywood cab pieces bank together to aid gluing: Below: Cab clamped while the glue sets. After glue-up, the cab edges were notched on the table saw to accept the oak edge members: Red oak edge members were inserted and held in place with painter’s tape while the glue sets.

DIY enclosure plans for the Jordan Eikona 2 - from a compact bookshelf speaker to floor-standing transmission lines, including the famous Jordan VTL.

This is my room plan – 6.1m x 3.6m (20′ x 12′) – showing the ‘compound’ Mid-Basshorn cabinets: The driver was originally a Lowther PM4. (Very costly and high ma…

Our highest-performing loudspeaker design to date is the Jordan Eikona TL Array, launched in February this year. It features four Eikonas and is capable of bass to 30 Hz. Its considerable power-handling enables it to tackle the full range of music, from orchestral and rock to string quartets and solo voice. The …

The bass reflex speaker design will give a +3 dB efficiency over the sealed subwoofer, reduced distortion, and higher power handling.

Horn loudspeakers are the best when it come to efficiency, but they are too big for woofers. The folded horn speaker design solves this.

Speakers (also called loudspeakers) push and pull surrounding air molecules in waves that the human ear interprets as sound. You could even say that hearing is movement detection. So what makes a speaker travel back and forth at just the right rate and distance, and how does that make sound?

B&W Nautilus speakers are legendary, both for their audio performance and their iconic cabinet shape. No surprise, audiophile loudspeakers like this are for rare and expensive, probably the reason IKEA Hacker, Damir Paco of Denmark, dreamt up a much more affordable DIY version using a trio of IKEA wood salad bowls and some BAREN clothes hooks…The inspiration? The Bowers & Wilkins Nautilus are fashioned after the beautiful marine creature with the logarithmic spiral shell.
