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 Nirvana, we were one of the largest sellers of Lowther and Fostex full range speakers.  We continue to be dealers for Lowther.  With Audio Nirvana we are now one of the largest manufacturers of these types of speakers anywhere in the world.

20 years ago, after many years of using other company's products, we decided to build our own range of high efficiency DIY full range speakers--Audio Nirvana.  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.

A lot of work goes into making a true high efficiency full range speaker, one that approaches 20,000 hz in the treble. And it's expensive. It is necessary to fit powerful magnets to obtain these high frequencies. Our Audio Nirvana full range speakers use magnets as strong--or stronger--than any other full range speaker.

Getting the midrange 'right' is especially difficult.  It takes extensive testing to optimize the many design elements.  In the end, Audio Nirvanas are the most detailed speakers that money can buy.

Getting the bass 'right' is also a difficult proposition. What should the cone excursion be? What type of material should be used for the cone, the surround, and the spider? What size of voice coil should be used? What type of wire? We have optimized all of these variables to bring you smooth, full, and very quick and precise bass response.

We have a policy, at CommonSense Audio, that we won't sell a more expensive speaker, unless it sounds better.  If you pay more, you will get better sound.  So, our 15 inch has better sound (the best sounding speaker of all time......or your money back), but our 15 will not fit in our smaller bookshelf cabiuets or smaller floor standing tower cabinet.

Generally speaking, a well designed larger cabinet is always better than a well designed smaller one.  Similarly, a well designed larger full range driver is always better than a well designed smaller one.  Why?  We can't say for sure, but our guess is that the larger cone can more accurately reproduce vocals and most musical instruments.  They are closer in size to the instruments (and human diaphragm) they are trying to reproduce.  There is a fullness and richness to larger full range speakers that most smaller ones just can't achieve.

In the past, the main reason to use a smaller full range speaker was because a larger one wouldn't go high enough in the treble.  However, our 15 inch full range has extension beyond the limits of human hearing .  So, unless your cabinet choice requires a smaller speaker, we recommend purchasing our 15.

All Audio Nirvana speakers use the highest quality cast aluminum frames, not cheap pressed steel sheet metal, as many companies use.

We'll be happy to discuss your particular needs. Just call or email us.

Audio Nirvana DIY Speaker Kits

Some of our cabinet designs for the Audio Nirvana full range DIY speakers.
Left to Right: 2.8 MkII, 2.8 Series 1, 1.3, Minimonitor, and Micromonitor

99.99% of all speaker cabinets ever made are 'bass reflex' designs.   We feel that PROPERLY DESIGNED bass reflex speaker cabinets give the best possible sound.  But full range speakers are not woofers.  The cone has very limited excursion (movement), known as Xmax.  Because of this,  full range speakers require different sized tuned ports to achieve the best bass.  No other company we know can properly tune bass reflex cabinets for full range speakers.

However, Audio Nirvana full range speakers can work well in bass horn, transmission line, open baffle, and infinite baffle cabinet designs.   These require 'short excursion' drivers (speakers) and that's what all Audio Nirvana full range speakers are.

We offer more than 15 different bass reflex and open baffle DIY speaker cabinet designs for Audio Nirvana full range speakers.  You will receive a free cabinet plan, parts list, setup tips, and pictures showing proper damping material installation--with any purchase.

Please note that Audio Nirvana DIY full range speakers are only half of your project.  The DIY speaker cabinet is the other half.  If the cabinet is not right, the overall sound will not be right.  Because most Audio Nirvanas are built as kits, some may not have been built correctly.  It is very important to us that EVERY Audio Nirvana customer get the best possible sound.  If you build our cabinets EXACTLY as designed, you will get great sound.  If you bought DIY speaker cabinets, for our full range speakers, or purchased Audio Nirvanas already built by someone else, please check with us that the build was done correctly.

For those requiring a smaller system, we have three different 'bookshelf' size bass reflex DIY speaker cabinet designs available:

The Micromonitor (.41 cubic feet or 12 liters) was designed primarily as a surround DIY speaker for home theater.  It still makes a nice 'extension' speaker for small rooms.  It is also an excellent computer speaker.  You can supplement it with a subwoofer for more bass output.  Many people also choose it as a center channel speaker.

The Minimonitor (.87 cubic feet or 25 liters) is really our smallest stand alone system.  It has full bass and dynamics and a satisfying overall balance.  It also makes a wonderful center channel or surround speaker.

The Monitor (1.5 cubic feet or 43 liters) is our largest bookshelf system.  It gives the bass output of many floor standing systems in a smaller package.  As with all the bookshelf systems, they can be placed upright or on their side.  This DIY speaker cabinet will accept every speaker size up to, and including, 12 inches.  There is also a Monitor MkII version which has a thin front baffle, but is deeper.  The difference is mainly in the styling.  Both of these can be used on the floor, as the dispersion of all Audio Nirvana high efficiency DIY full range speakers is wide enough that stands are not required.

For those who want a floor standing system, we have the following bass reflex systems available:

The 1.3 (1.3 cubic feet or 37 liters) is our smallest floor standing system. It makes satisfactory bass for those who have space limitations.

The 2.8 tower cabinet (2.8 cubic feet or 80 liters) comes in two versions. The Series I has a wide front baffle, but is shallow in depth. The MkII has a thin front baffle, but is deeper. The difference is mainly in the styling. Both versions are available with two different porting arrangements. The "Big Port" version offers more mid bass at the expense of some low bass output. The "Twin Port" version has 1/3 octave more bass extension, at the expense of some mid bass output.

We also offer two different dual driver designs: the 2.8 Dynamic and the 2.8 Ambience. The Dynamic gives a big, powerful sound while maintaining the same overall tonal balance as the normal 2.8. The Ambience puts a lot more 'weight' in the bass and adds a sense of 'air' to the music. It's our favorite version of the 2.8 if you use 8 inch speakers.

The 2.8-15 is specially designed for our 15 inch speakers.  It gives all the sensational sound of our 15's in the smallest possible cabinet.

The 5.6 or 5.6 MkII (5.6 cubic feet or 160 liters) offer more bass and dynamics, in a DIY speaker cabinet that is not too large for most rooms.   The 5.6 MkII is narrower and deeper, but will not accept the 15 inch speaker.

The 8.0 (8.0 cubic feet or 227 liters) is for those of you for whom WAF (wife acceptance factor) is important.  It looks like the smaller 5.6 from the front, but is 5.75 inches deeper (146 mm).  It has more bass and dynamics than the 5.6, but doesn't really look that large.

The 13.6 (13.6 cubic feet or 385 liters) is a huge cabinet that maximizes performance of our 15 inch speaker.  It can even hold two 15 inch full range speakers.  It's the ultimate!

And for those of you looking for something 'different', we offer an open baffle speaker type of cabinet:

The Open Baffle speaker is basically just a piece of wood supported by two 'wings' to hold it upright. Open baffle speakers don't generate a lot of bass and usually roll off below 63 hz. However, the sound from the back of the open baffle speaker is free to reflect off rear walls and join the sound from the front of the speaker. Open baffle speakers give a 'fat' sound that is very nice for classical music or for people favoring this type of sound. Supplemented with a quality subwoofer, open baffle speakers give an unusual presentation.  Open baffle speakers work best with the largest high efficiency full range speakers which can generate more bass without the help of a cabinet.  Open baffle speakers are also a way to enjoy our best 15 inch speakers, without requiring a large cabinet.  We are experts on open baffle speaker designs and have many years experience.   If you go to www.openbaffle.com you will come to this site.
