The concert hall sound you can actually achieve in your room... And now, you are on stage with the band! Many speaker producing companies try to do their best to give you this impossible dream and some do... at the price levels of a fast family car! The reason is its extremely difficult to obtain an ultimate formula to please everyone in every room...

​

Every room has different acoustics and resonances, and every ear has routines to that environment. Every part of your system has a ''sound''... even your cables. After choosing your turntable or a quality cd player, streamer, it's very difficult to choose best companions; amplifier and speakers, just like choosing best bodies. We believe honesty and simplicity are the best solutions to this. When choosing an honest speaker, it should be beyond the complex formulas to please everyone... it has to be reasonably priced and it has to please just you!  It should be simple enough just to give some alternatives to you...That's why some of the industry began looking for the answers not in the complexity but in the simplicity. As simple as it gets, they are full-range single driver speakers, without electronic parts and cross-overs...

​

In recent years there are many developments in point source full range single drivers. The major problem was they didn't have enough wide frequency responses and high efficiency in the past... But now they do! They have enough db to work with the tiniest low-watt tube amplifiers. You don't need that extra gain of your active pre-amplifier. The 8" Alnico driver can give 40hz to 20khz  (-/+3db) with 96db efficiency in our smallest speaker cabinet. (Most music in the markets have roll-offs starting between 40hz and 50hz.) If you want to search more deep down than 40hz in our monitors, we recommend subwoofers... Actually bigger the volume of cabinet gets, the deeper the bass.  The 10"Alnico with our "Big Boy" cabinet, we perfectly have down to 30hz with 97db efficiency.

​

Full-range, single speakers have many undeniable advantages. They are highly efficient, extremely detailed, 3d (like you're there sound) and dynamic. No cross-over or an electronic circuit is on the path, the sound is the purest, organic and most fluid... and never boring!

​

They have only 1 disadvantage. They are not the best in balanced sound character. They don't have flat response. Even the most expensive ones usually  have high peaks around 5khz to 8 khz and rarely between 8 khz  to 11 khz...  Usually the bigger the driver gets, the more un-balanced  they become. (But bigger the driver gets, more full-body sound character they have as well) This problem can not be fully eliminated in the driver design or production process. But choosing the size and magnet is important in this manner. That's why we mostly work with 6.5"Alnico, 8" Alnico or 10"Alnico drivers, the ones without whizzer cones has to be preferred if wide dispersion of treble is not wanted (but we still prefer the ones with the whizzer cones) and there are things to tame that peaks in the speaker cabinet design, stuffing, placement or digital room correction.  For us being cross-overless is way better even with digital room correction or eq. And most conventional speakers which are supposed to be more balanced also need digital room corrections (according to our measurements) as well... 

​

Lowther is one of the best known company that produces full-range drivers. They are indeed highly efficient and very detailed. But still expensive. The prices of Lowther Alnico drivers start from 1500 USD...  And many Lowther speaker designs are massive horn designs which need massive areas... Fostex is another well known company that produces good full range speakers... some say their 8" Alnico drivers are the most balanced (not like Lowthers) but still, not in the level of best in high efficiency and detail areas. Mark Audio Alpairs are recommended but don't have drivers bigger than 8" (so no full-body sound of a 10"driver) and they need horns for bass as well. There are better brands such as PHY, Feastrex, Voxativ (even better than Lowthers in most areas) indeed, but a lot more pricey than Lowthers. (some models more than 3000 - 4000 euros...)

After our research we discovered Audio Nirvana speakers. It's in the range between Lowther and Fostex in capability and most reasonably priced according to their sonic capabilities. They have every size drivers. They are sold by Commonsense Audio... The firm sells Lowther and Fostex drivers also, and produce their own products in the same factory, which makes the prices reasonable... Up to now, with all our research, and with all our experience in listening to more than 250 speakers, Audio Nirvana's was our final decision!
