Audio Nirvana coax 15
 
Hi There,

I was looking to buy a Audio Nirvana 15" Co-ax that come with a compression drive or to use a normal Audio Nirvana 15" with an external ribbon tweeter. I know many people tell me the AN 15" does not need an extra tweeter, but I am not convinced with a paper based cone.

Ideally the compression driver would be a better match than the ribbon tweeter, since it is built into the speaker driver. However I am clueless about how the sound characteristics of a compression driver?

Would love to hear some feedback if you have heard or used the AN 15" coax.

Thanking ahead.

Oon,
Melon said that you willl not want to add tweet and i fyou did, he would not take anything less than Beyma TPL or RAAL.

Errr
Tell Melon that the tweeters he is talking about costs more than a pair of 15" AN.... sorry don't really have that much money, even if I sell both my kidneys... don't need kidneys to listen to music...:(

I have a pair of Mark and Daniels AMT. Or I might buy this one...

Bohlender Graebener Neo8-PDR Planar Transducer 264-713

Incidentally I will pm you to get his contact will probably want to ask more info from him.

I think the question from me is whether I shoudl get the coax or should I just get the supercast 15 and add in additional tweeter....

Or maybe get supercast 15 and then decide if I want to add in additional tweeter...

second from bottom Fountek (with horn) , from 75E in Europe for pair

or APT80

both crossed anywhere between 15-20K 6db/oct

they will work flawless as supertweet

series R will suffice if att is needed

edit - this one - http://www.fountek.net/products.asp?id=43

I own the AN cast 12 , no need for a tweeter unless you have incredible hearing

Zen Mod 11th October 2012 02:16 PM

agree , but almost ;)

even if my hearing is ooked above 14-14,5K ( too many hours in front of stage on concerts ? :rofl: ) , I'm finding supertweet welcomed with coaxes and FR spks ; none of them is anywhere mentioned as lacking in upper region

whatever , I had same impression as you , but only after trying supertweet I change that opinion

usual disclaimer - YMMAMV ;)

oon_the_kid 12th October 2012 11:24 AM

I agree with Zen over there. Sometimes when you add a supertweeter to a system, there is a big improvement in sound. The sound can feel more airy. I heard the improvement even when you stick it in a 2 way unit. And definitely with my seas fa22 full range. It is not something you can hear per se, like this wasn't here earlier, now it is. Just a general feeling of clarity and when you take it off, it feels like something is missing.

I have a aurum cantus on another system but i might canibalise that and put it here...

and , as I said - you don't need left leg and right kidney value here - Eminence APT** is completely enough and dirt cheap

** - APT50 is code for naked driver , without plastic horn ; with horn it goes from 80 upwards , higher numbers having bigger horns and different coverage angles

taking ferofluid out clears things further

boyz from Zu are using it , same as guy in States ..... for improvement over basic Klipsch tweet , same as guys in Eu , making some expensive boxies with coax Eminences

not my cap of brew as tweet , but as helper tweet - more than good enough for sparkling some air

I thought I'd hate compression tweeters but since trying and enjoying the Eminence 1001 (I think it's cheaper than the apt 80) I'm completely sold on them. I think pairing them with appropriately efficient drivers (like the Eminence 12lta... and certainly others) produces very lively results for a home speaker.

Why not go the route of the 15" Cast AN and get a good quality tweeter crossed over like a typical 2-way? Plenty of good ones that would work well.
