Speakers and Room acoustics  

The research...

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 mechanical part of your system has a ''sound''... even your cables. After choosing your turntable or a quality cd player, its 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!  (And wife acceptance of course!) It should be simple enough just to give some space to you...That's why the industry began looking for the answers not in the complexity but in the ''ancient speakers built''. Since they were 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 frequency responses and powers... But now they do! Lowther is one of the best known company that produces full-range drivers. They are indeed efficient and very detailed. But still expensive. The prices of Lowther Alnico drivers begin from 1200 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 very capable in power, image, depth and tone areas... There are many good brands such as PHY, Feastrex very good (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 very reasonably priced. 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 200 speakers, Audio Nirvana's was our final decision!

Audio Nirvana

After choosing our brand, with Audio Nirvana's owner David Dicks' help, we now have the experience of designing a simple bass reflex speaker with no cross-overs and complexity... The driver just connects to your amplifier with the best reasonable cable you can afford... and nothing else interfears... Why bass-reflex??? The reason is obvious, David Dicks says at least 90% of all speakers produced up to now is bass-reflex. It's a very simple design and easy to built. The other factor is the Audio Nirvana drivers are capable to compensate the negative sides of bass-reflex design... especially the ones with Alnico magnets.  He explains briefly why he chooses bass-reflex design in his site, commonsense audio.

After choosing our brand and design type we researched more about the acoustic design and the room. The relationship with the speakers and the room you're listening to is the major point... sometimes they can be enemies! There can be major resonances, which can be produced by your speaker and can be ''rejected'' by your room. Standing waves are a major problem... So you have to make acoustic treatments to your room... but, that can be made up to a point!  And nobody wants to spent a fortune to see massive sound treatments on the walls!!!

And now another conclusion...

You're not listening to your speakers...

You're listening to your room.

So, how expensive your high end system, how latest tech. your speakers are totally a waste! nothing but ego...

After finalizing our thoughts we simply can apply the formulas that a better sound can be achieved for less money by designing the speaker as simple as we can according to our room resonances... 

What we do...

We simply learn what you need, measure your rooms acoustic responses and choose a driver with you from Audio Nirvana, according to your budget, and design a bass-reflex cabinet for that driver, according to the listeners hight and position measurements, make adjustments according to the response of the room behavior. We apply acoustic treatments in your room and sometimes use digital eq with microphones for ultimate acoustic corrections. We eliminate the negative sides of bass-reflex design, the resonances of the room as possible as we can... , built a 18mm MDF + 18mm Plywood or (36mm Plywood if needed) cabinet  with braces and sandwich panel damping system (with rubber-roofing felt if needed) have it painted and veneered the color you want.Then put a hard rubber feet we designed (Angel's feet).

 

Finally connect and position them to the right angle and displacement from the walls according to the measurements and calibrate the system.

ENJOY your tailor made best quality suit ! For an affordable price...

Can any ready made suit be better than this???

Angel's Feet

Devil is in details... We designed a ''spike - look'' feet with a hard rubber... its upper part is 80% hardened rubber and floor touching part is ''ball shaped''... 3-5mm touching on the floor.  It handles the shock resonances  between the speaker and the floor just like an expensive spike, but unlike a spike, it prevents the  movement of the speaker, and it doesn't scratch the floor. Hight adjustable and durable.
