Audio Nirvana High Efficiency Subwoofer. Speakers are available in: 3" 76 mm4" mm6. Audio Nirvana is the only company that has ever made true full range speakers larger than 8 inches. 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. Almost all Lowther and Fostex models use whizzer cones.

Ferrite offers the best value. Neodymium rare earth magnets offer the highest efficiency and most detail. Alnico magnet models are the smoothest, richest, best balanced, have the most bass, and offer more detail than Ferrite magnet models. All Audio Nirvana DIY speakers use strong, beautiful, cast aluminum frames--not cheap pressed steel sheet metal as most companies use.

Audio Nirvana high efficiency DIY full range speakers have better sound than any other speaker and better build quality than any other speaker. We have been designing, building, and selling high efficiency DIY full range speakers--using full range drivers--for more than 25 years now.

Before we started Audio Nirvanawe were one of the largest sellers of Lowther and Fostex full range speakers. We continue to be dealers for both Lowther and Fostex. With Audio Nirvana we are now one of the largest manufacturers of these types of speakers anywhere in the world. There were problems with all the other full range speaker designs available and we decided we could do better. We have. And, for the first time, it's possible for you to buy directly from a manufacturer.

In this way, you get the most value for your money AND the best sound possible.It makes use of the same basic design concept of the Medallion, such as a back loaded horn for the bass and mid-bass, while remaining a direct radiator for the mid-range and highs. They feel traditional woofers require a much larger mass to perform the task and thus are not as fast. According to Jon Ver Halen of Lowther America, their initial design goal was for bass extension to reach 80 hertz, a point where most sub-woofers could cross-over.

When the units were being built and tested, they were pleasantly surprised that they could get bass extended to about 45 hertz. At this level, most people would not require a subwoofer. They also contracted with the late Terry Cain to build the cabinets. The result was a much more updated look. So I found it interesting that this speaker showed up while I was doing this survey of mini-monitors. In fact, not only does the footprint compare, but their height is about the same as most of the mini-monitors when place on their stands.

One last comparison to the speakers in the mini-monitor survey I have been doing would be price. They make an interesting comparison, I think.

In the Alerion, you get a small floor-standing speaker, that images better, has a more three-dimensional soundstage, and is more dynamic than any of the mini-monitors. Lowthers have been manufactured in Britain for nearly 70 years. When I started reviewing for Dagogo, Constantine asked me what I would like to review, and the first thing I said was a speaker that uses a Lowther driver.

Well, now I have had three different ones in less than six months, and they were all three worth waiting on. Let us admit it, Lowther speakers have not been for everyone. Over the years, almost all the successful attempts at Lowther enclosures have been horns or pipes of some design. Again, most of these have been rather large, and often not high on the list of wife-pleasing speakers. Also, it is very easy to damage them, then it is very expensive and time consuming to have them repaired.

To the lovers of really alive, dynamic sound and for the connoisseurs of SETs, the sound of Lowthers are well worth these few problems. The Alerion keeps most of what is wonderful about Lowthers; including the dynamics and does this in a nice, modern looking, small cabinet. As many of you know I am a big fan of the finer SET amps and of speakers that do not use crossovers. The Alerion is the third single-driver speaker I have had in house in the last year and the second with the smaller Lowther DX 55 driver.

Readers may remember how much I like the Teresonic Magus, a small stand mounted, monitor type speaker that uses this same driver. So, it was with great anticipation that I unpacked the nicely done cabinets and installed the drivers. By the way, the cabinets were built by Cain and Cain and the quality is obvious.

Today, there are lots of choices in low-powered amplifiers from the new inexpensive chip-based amps all the way to 1. Then, there are plenty of wonderful low-powered amps in between. While a larger variety of amplifiers have become more and more available, there are still very few speakers that really work well with these little precious jewels we call SETs.

Thus, when one comes along that is reasonably priced, of a reasonable size, and truly can be driven by amps with only single digit output, it is reason to take note; that is what brings us to the Lowther Alerion.

This may not sound all that efficient, but when the bass of such speakers drops off rapidly below 45 Hz and the amp is not strained trying to produce the lowest bass, such speakers are able to produce more apparent volume than a full-range speaker.

What they have done is re-create their classic Medallion cabinet to work with the Lowther DX 55 driver. The Alerion is just what it looks like: a simple rear-loaded, exponential horn.

As a result, a speaker with very high sensitivitythe legendary Voigt Corner Hornwas born.

Powered with the low-output tube amplifiers of the day, a horn speaker could push enough air to fill theaters with sound. Voigt soon joined up with gramophone manufacturer Peter Lowther; since then, the basic concept of a Lowther speaker has not changed much. The principles of horn loading are still the same, and the return of tubes especially single-ended designs completes the picture. Sometimes when I listen to my Lowther system, I am reminded that this design can compete with all kinds of modern, expensive stuff.

Tell me, what did we gain in all those years? Reproducing live concerts in the home isn't really possible. With the help of electronics, one can only hope to get an impression. Though the differences between the acoustical environments of the listening room and the concert will remain, once in a while, depending on the equipment used and the reliability of the recording, we get an impression that gives us the idea or the feeling of being present at that concert.

Live recordings often take place with microphones in specific places to record a stereo "image" of the performance at a certain distance. This explains why symmetrical positioning of speakers is important for playback, and also why you have to sit centered in front of them to experience the acoustical environment of the recorded space correctly.

A microphone is a point source that records the whole sonic spectrum with only one diaphragm. However, conventional speakers are multiway systems with woofers, squawkers, and tweeters each producing a limited range of frequencies.

To reproduce sound correctly, they also require a crossover filter that divides the signal into the ranges needed by each driver, which introduces phase shift.Search form Search.

A microphone is a point source that records the whole sonic spectrum with only one diaphragm. However, conventional speakers are multiway systems with woofers, squawkers, and tweeters each producing a limited range of frequencies. To reproduce sound correctly, they also require a crossover filter that divides the signal into the ranges needed by each driver, which introduces phase shift.

Because a multiway speaker uses more diaphragms than a microphone, it can't reproduce the music accurately. Using a wideband loudspeaker gives the desired point source without the need of a crossover. Adding an amplifier with a simple wire diagram and just a few components, instead of the complicated high-powered designs of today, will gain even more detail, more music, more reality. Most simplified amplifiers single-ended, or SE suffer from a minor problem: their power is often limited to watts.

If you like to hear the dynamics accurately, you'll need an efficient speaker such as a Lowther horn with a very high sensitivity greater than dB. There are, however, some disadvantages. One is the lack of spherical dispersion above 12kHz. However, this is not really a problem if we are sitting between both speakersjust point them in the right direction!

If you desire to have deep low frequencies, you'll need a rather large and expensive horn design like the TP1 or the Opus One. Properly placed in the corner, they will give a nice response greater than 30Hz with only one speaker!

If you do not have the money or space for these, then you have to live with less bass nothing below 50Hz. Luckily there are several great-sounding horn-loaded designs for free-standing use. The bass will be slim, but more then enough for the most recorded music. Purists will remind you that there are not many instruments producing frequencies below 50Hz, however.

Personally, I like bass that lifts the music, giving a real foundation to the sound.

Imaging is wonderful. The Lowther EX4 gives you A 3 watt 2A3 tube is enough to drive the speakers beautifully. Due to its high sensitivity characteristic nature, you can hear lots more details that are missing from other speakers. There is a recent trend in audiophiles to go with the combination of high sensitivity speakers and low power amplifiers.

In order to produce the lowest frequencies, they need to be attached to a horn. They are much like a compression driver in this respect. A rear horn allows the driver to transform its small excursions into large volumes of moved air thereby increasing bass efficiency to match high-frequency efficiency.

Horn bass has a purity of tone that is unrivaled. There's no boom, and no such thing as 'one note' bass. The bass from a Lowther horn has an articulation unlike any other speaker.

I miss my Lowther Medallion II loudspeakers. A lot. I had them for a while in and got to hear some magical sound. Tony Glynn of the Lowther Club of America he is the Lowther Club of America is an extremely charming and well-informed gentleman with a great love of the history of audio and a single-minded devotion to this loudspeaker.

When Tony and I first began discussing the speakers, the only things I knew about them was they were British, they were a good choice for low powered amplifiers, that Jimi Hendrix used to blow up a lot of them in his listening, and that there is a cult-like devotion to them. The first thing you notice about the Medallion cabinets is the expression on the face of the delivery person as he thinks about whether his health insurance premium is paid up. There are a couple of wiring upgrade options available.

The Lowther PM5As are smallish Most of the heaviness is the magnet which is Alcomax3, a special alnico formula. These are powerful magnets. The drivers were amazingly well-made, a pair of powerful British bulldogs which I fantasized if hung from a crane, could lift a Buick. The second cone has its own single layer voice coil and handles upper midrange. The "bullet" in the center pushes out the highs. Every male seeing the Medallions said something like "Wow. What do they sound like?

When asked about this, my friend sighs and makes the face of that guy in the classic lumpy gravy commercial. All women certainly do not have issues with large loudspeakers in their homes.

They are rear-loaded horns. The bass frequencies come off the back of the Lowther driver, and the midrange and highs both come coherently from the front of the driver. It kind of looks odd, that "little" driver staring at you from that big box. To be fair, looking at them dead-on the Medallions appear like reasonably sized living room speakers. Black fabric grille cloths are "just for show" and Glynn recommends taking them off for listening and replacing them to protect the voice coils from dust.

I also think the sound of the Lowthers may have something to do with wood, shellac, and breaking in. One of the first things Tony Glynn told me about the drivers was "these PM5As have about hours on them and are broken in.

When you read any of the literature and lore of these speakers you discover that the British makers contract for special cone paper, a secret recipe of four different species of wood. They also use a special lacquer on the cones, the result of a lot of experimentation, which also needs time to break in.

This stuff is right out of the Stradivarius instruction book. Psychoacousticians and instrument makers have endless graphs, charts, scope printouts, and back room debates about secret varnish recipes, and which growth of spruce or maple makes the best sound. And flamenco guitarists all know that older guitars sound better, and if you stop playing one for a while you must break it in all over again. This suggested to me the necessity for a gradual and subtle series of adjustments in the voice coils and cones which only musical frequencies played in real-time can accomplish.

I can however say that over three or four months this pair of hour-milage drivers "opened up," "relaxed," and "got it together. Supposedly magical midrange.
