Page 1 of Forum Tools.Single driver speakers are very popular and have many advantages, primarily simplicity, ease of drive, and excellent performance.

However, most single driver models require horn loading. There is nothing wrong with horn loading but the cabinets are difficult for the hobbyist to build. Bass reflex cabinets are much simpler to construct and consequently were selected for this project. The driver used is the Tang Band W It has an efficiency of 95 dB for one watt. All Transcendent Sound amps can easily drive this speaker.

Single driver speakers suffer from a response anomaly in the upper registers. They all have a steadily rising output with frequency and this speaker is no exception. Not taming the rising output will cause the top end to be very hot and peaky.

An adjustable attenuation network has been developed to correct for the rising output. Notice in the graph below, the output slopes up above Hz. The attenuator must level out the response to equalize the output. Calculations show that a microhenry 0. Using a ohm, 50 watt L-pad set at mid-rotation provides 8 ohms and yet still allows for considerable range of adjustment. The inductor was glued to the back with 5-minute epoxy. At center rotation, the network gives the following measured electrical response:.

This very closely matches the desired characteristic.

At maximum attenuation, the following electrical response was measured. The difference is primarily in the top octave. Setting the L-pad at minimum resistance effectively takes the network completely out. Use the left and center terminals of the L-pad as viewed from the rear. Do not follow the instructions that come with it. The inductor is an air core unit with 18 AWG wire.

The cabinet volume is 3 cubic feet. External cabinet dimensions are The vent is 4 inches in diameter and 4 inches long and is shown mounted in a plate because it was reduced in size.

The initial size was 6 inches in diameter and 2 inches long. This was too under damped and caused excessive boomy bass. The selected size over damps the speaker, which extends the bass to well below 50 Hz and removes the thumping.

It also has the beneficial effect of cleaning up the midrange because of the reduced cone motion. Damping was provided with 1.

Line the top, bottom, sides and top half of the back. No damping on the front panel. Damping is a personal taste issue so use what sounds best to you. Same goes for the setting of the L-pad.Home Audio Nirvana. Are you tired of all the hype from advertising driven websites, magazines, and dealers just out for your money? Tired of '4D' speakers?

We don't build larger full-range speakers for more bass, but for astonishing midrange and treble. A special proprietary design makes this possible. Any whizzer cone model is not truly a full-range speaker, but a two-way speaker where the tweeter cone is glued to the woofer cone.

But whizzer cone full-range speakers are still much better than multi-driver speakers with a crossover. Ferrite offers the best value.

I'm a little confused about adding a super tweeter to my full range speakers. I am driving my full range 4 ohm speakers with my LM GainClone amp and want to add tweeters for those extra highs. Some of the commercial 'super tweeters' I have seen have built in crossovers and attenuators, but connect in parallel to the main driver.

Surely if you don't have a crossover on the full range speaker, at certain frequencies the amp would 'see' a very low impedance as you have the full range driver and tweeter both being driven by the amp. My LM amp runs my 4 ohm speakers fine, but if I added an 8 ohm tweeter, at certain frequencies when the crossover allows the signal to the tweeter, the amp would see both speakers in parallel. I know the impedance of the speakers change at different frequencies, but is it safe to just add a tweeter crossed at say 6K Hz, or should I build a crossover for both?

I have to answer "it depends" First, remember the full range impedance raises quickly at higher frequencies. All that copper in the voice coil you know. I am sure the OEM can provide you a plot that shows this. You did not describe your full ranges or if they have a Zobel or other compensation networks, as that can change everything.

In other words, safety wise, I agree with sofa, you should be fine. But, you are not adding an 8 Ohm tweeter, but a variable impedance that does not dip too far below 8 with some crossover that may or may not raise the impedance. You are actually asking a very complicated question for us to be exact in our answer. Say, the tweeter has an L-pad on it.

Now you ARE putting an 8 ohm load across the entire frequency range, unless the pad is inside the crossover. It depends. Just adding a tweeter without a complete two way crossover only gives half the advantage the tweeter could provide and may be very difficult to integrate. All drivers have breakup modes. A full range may actually "use" the breakup to give the impression of extended highs so you only need a little "air" on top. But, if you added a complete crossover, you can reduce that distortion and get the highs too while making the integration easier.

Just adding the tweeter may give you ugly peaks where the full range is breaking up the worst causing difficulty in overall balance.Is there any advantage using a single full range driver rather than a two way speaker box?

It appears even the Bose box demensions and port size is compatiable with the Fostex full range. Single driver speakers are most suitable for the more intimate genre and at moderate volume levels. This includes solo voice, small group jazz and 18th century classical and chamber music. For these genre, single driver speakers are superb. You will hear nothing better. They also do classic rock pretty well as long as the volume is kept to reasonable levels.

Now, if you are into heavy metal or want Mahler symphonies at concert volume, I suggest that you look elsewhere. You will be disappointed and I have to eat shipping costs and try to unload a custom pair of speakers at as little loss as possible. Single driver speakers have a unique sound. That sound comes from a lack of a conventional crossover. In a two-way speaker, the acoustic phase of each driver rotates in opposite directions around the crossover point.

While the combined phase may be correct at the crossover point, away from that point, the phase will be constantly changing. Why is this important? We are very sensitive to phase in the Hz range.

Outside on this range, sound location becomes increasingly difficult, but within this range, if the phasing is messed up, the sound stage lacks precision and depth. A normal two-way speaker has the crossover point in the middle of Hz range, which is smack in the middle of the frequency band where humans are most sensitive to phase changes. By not having a crossover and the attendant phase problems, a single driver speaker sounds much more natural.

A good single driver speaker is more articulate and detailed in the bass and midrange that a multi-way speaker.

Because the driver in a singe driver speaker must work up to 10kHz and beyond, the cone is much lighter than the cone of a comparably sized driver in a multi-way speaker that is crossed out by 2kHz. Less cone mass means faster response to the electrical signal and better transient response. The lighter cones also promote higher efficiency.Near the bottom of this page are the older speaker projects that use drivers which are dnow iscontinued.

Last update: 1 September The speaker projects are listed chronologically. For more DIY projects, use the navigation menu on the left side of the page. Last update 1 September Once again Mark tries on the Fostex FEEn high sensitivity fullrange driver, but this time the end result is a large elaborate back-loaded horn loudspeaker.

The speaker cabinet plans are from the FEEn driver datasheet. The horn loudspeaker cabinets are made from 21 mm thick pine plywood and use a single FEEn fullrange driver and no crossover. Australian beeswax is used on the outside of the horn cabinet and heavy cedar oil was applied to the mouth of the horn. 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. This open baffle speaker project is simple to build and uses low cost speaker components.

The project was inspired by the "Big Air" open baffle system by Jim Strasser.

Bruce indicates that the speakers have an excellent overall sound but cautions that open baffle speakers systems are "bi-polar" and not for everyone. The enclosure is a 6. The loudspeakers use a single Fostex FEEn fullrange driver with no crossover circuit. The speakers work well as nearfield monitors and combined with a subwoofer the speakers can be used for home theater duties. The speaker box plans are from the datasheet that was supplied with the drivers.

The loudspeakers use a single Fostex FEEn fullrange driver and no crossover. The two chamber box design extracts good bottom end from these low displacement drivers. 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.

Mark reports that the speakers are an excellent mate for use with his 2.The resurgence of interest in full range speakers has led to a renewed exploration of the rear-loaded horn. This coupled with a whole new generation of more advanced computer-based modeling tools have given designers more power to generate better designs. F rugal-Horn. FH3 been shown to work with a wide variety of drivers.

More are being encouraged. With Fostex doing a complete revision of their popular full-ranges, most of the Spawn of Frugel-Horn became obsolete. Horns are typically more complex to build, and are not without other problems, but a well-executed BLH can be a real aid to enjoying the music -- and in the end that is what it is all about.

All of these will be supported by well developed plans some still a work in progress and links to community discussions on these specific designs. These horns are free to build for non-commercial use and licencing requirements for commercial ventures are not onerous. We hope that the builders add their own creativity and personality to their speakers. Frugel-Horn Mk3. Frugel-Horn XL. Frugel-Horn Lite. The original.
