The speaker enclosure uses a pair of ready made curved Dayton Audio 0.38 ft^3 with a black piano gloss finish. With the TangBand 25-1372SC tweeter the highs are crystal clear, detailed but far from harsh." The cost of the Ion speakers will be about $900 US and no doubt will also require plenty of hours in the shop as this is a challenging enclosure to build.ĭIY HiVi Research Swans M1 Speakers - 16 April 2010 - Ī DIY version of the HiVi Research Swans M1 bookshelf speakers put together by Daniel. Adam reports that the Ion speaker build is his favorite so far - "The Audax HM170CO woofers produce very warm natural tones up through the upper midrange. The enclosure is made of MDF and solid oak and each tower weighs about 60 lbs. The nominal impedance of the speakers is noted at 4 ohms and the frequency range is about 60 Hz to 20 kHz. The 2-Way crossover uses a 3rd order Butterworth filter at 4 kHz with an impedance correction circuit. The Ion tower speakers are a 2-way design that uses a Tang Band 25-1372SC titanium dome tweeter and a pair of 6" Audax HM170CO mid-woofers in a TMM configuration. The latest DIY speaker project by Adam is a great looking pair of ported tower loudspeakers call Ion. Ion - DIY 2-Way TMM Tower Speaker Project - 5 September 2011 Mark reports that the speakers are an excellent mate for use with his 2.5W 6EM7 SET amp. The speakers will be used in a home theater so for a non-reflective finish the speaker enclosures are painted with a undercoating paint for a stipple like finish and flat black paint. The two chamber box design extracts good bottom end from these low displacement drivers.
BOSE SPEAKER ENCLOSURE DESIGN DRIVERS
The sensitivity of the drivers is about 96 dB / 1W / 1m, so the double bass-reflex speakers are well suited for use with flea and low power tube amps.
BOSE SPEAKER ENCLOSURE DESIGN DRIVER
The loudspeakers use a single Fostex FE206En fullrange driver and no crossover. The speaker box plans are from the datasheet that was supplied with the drivers. Mark has put together his second set of the Fostex FE206En double bass-reflex speakers. The speakers work well as nearfield monitors and combined with a subwoofer the speakers can be used for home theater duties.įostex FE206En Double Bass-Reflex Speaker Project - 17 September 2012 The loudspeakers use a single Fostex FE103En fullrange driver with no crossover circuit. The enclosure is a 6.9 L bass reflex cabinet tuned to about 95 Hz that follows the speaker box plans included with the driver datasheet.
Gio has put together a small bookshelf / monitor speaker project using a single inexpensive fullrange speaker driver. Bruce indicates that the speakers have an excellent overall sound but cautions that open baffle speakers systems are "bi-polar" and not for everyone.įostex FE103En Bass Reflex Bookshelf / Nearfield Monitor Speakers. The crossover point is 3600 Hz and the speaker system sensitivity is 93 dB / 1 W / 1 m. The project was inspired by the "Big Air" open baffle system by Jim Strasser. A pair of these open baffle speakers can be built for $150US. This open baffle speaker project is simple to build and uses low cost speaker components. Mark reports that the horn speakers can draw an extremely accurate soundstage, sound excellent and have lead to a whole new listening experience with Paris, a 2.5W 6EM7 SET amplifier.Ĭobies - Cheap Open Baffle Speakers - 11 July 2013īruce shares his Cobies - Cheap Open Baffle Speakers. The sensitivity of the FE206En driver is greater than 96 dB / 1W / 1m, so the rear-loaded horn speakers are very well suited for use with very low power tube amplifiers. Australian beeswax is used on the outside of the horn cabinet and heavy cedar oil was applied to the mouth of the horn.
The horn loudspeaker cabinets are made from 21 mm thick pine plywood and use a single FE206En fullrange driver and no crossover.
The speaker cabinet plans are from the FE206En driver datasheet. Once again Mark tries on the Fostex FE206En high sensitivity fullrange driver, but this time the end result is a large elaborate back-loaded horn loudspeaker.
