new living voice prototype horns

Bass boom will almost always be down to room modes. No one designs a speaker that booms.

 

what is the purpose of having a vertically placed horn? i've seen it on some recent JBLs aimed to home theatre systems.

 

One would hope not! Is the enclosure on the Aspara sealed ,It says 'horn type' on their website.

 

Hi,

I too thought these sounded promising when I heard them last year. I didn't get to hear them at this years show. I understand that Murray (on this forum) has heard them recently and came away very impressed.

They are £6000 in the UK & $25,000 in the US it seems. At £6000, they are worth a look.

No it's an exponential that vents out of the base. - but of course only down to a certain frequency much like yours.

 

And yours.

 

Mine aren't horn loaded at all Keith - simple bass reflex.

 

ATC use a sturdy 'soil pipe' from their local B&Q.

 

Its my understanding that it's used in order to keep the profile of the speaker itself slim.

This is what I've read, I can't remember where - so take my answer as 70%

Obviously the dispersion characteristics change by moving it.

 

Probably does the job - no need for anything fancier really.

I questioned the designer of the JBL Array about the philosophy of the vertical horn. He said that the diffraction slot used in the throat of CD horns works better when aligned vertically. Personally, it looks more trouble than it's worth to me given that I would expect pronounced reflections off of the floor and ceiling. However, I'm no expert and Greg Timbers is.

 

plus it would be expected to make a sweetspot even smaller.

 

Another Horn...

This one looks nice, just cannot find the supertweeter...

Sorry Antonio, I've never accepted the compromises involved in FR speakers. I am aware of the distinct advantages in some areas but to me, as soon as you start asking drive units to cover much more than three octaves you start running into problems, particularly if they are horn loaded.

Just my personal perspective, and the closest I think I could come to a single driver would be a Tannoy DC. Obviously all speakers are a compromise and we each have to choose those that we can happily live with. I can live with a little phase error in the interests of linear cone behavior and proper impedence matching across the audible spectrum.

The only rule I have learnt to be an ultimate truth if you like is that a good big one will always better a good little one. In life as in audio.

 

I understand that people have different tastes, after all, we ear different, so it could not be otherwise...

For me the biggest problem is crossovers, after everything else is reasonable, of course...

Still I need subwoofers and supertweeters, as I like extended response, who said it was easy...

 

You need more than subwoofers and supertweeters if you are going to accurately reproduce a full range signal. And they do far more damage than a well designed crossover in a quality loudspeaker - they have no direction in their crossover design - adopting a "one size fits all" approach which is hopelessly compromised IMHO. Full range One Way's throw the baby out with the bath water IME.

 

Both subwoofer and supertweeters can be adjusted, unlike yours well designed crossover in a quality loudspeaker

I screw extreme bass and treble, you screw the midrange, guess whos better off...

Again, you choose your lesser devil, I choose mine...

 

I've only heard them at shows and under those conditions thought the were decent enough but wouldn't have me coughing up any cash. The older Impulse models are a tough act to follow if you want a good taste of what horns can do in a manageable and domestically acceptable form, though it's funny how familiarity with large boxes makes them shrink as everyone else who sees them thinks they are bloody enormous.
I've just replaced the Focal TC90k tweeters in mine for new TC120 TiOxid versions which drop in - freshens them up nicely.

 

Sorry Antonio, I have far more adjustment than you could dream about But for most people adjustment is a bad thing. Crossovers take a great deal of work to get right - work you cannoy do without the correct measuring tools, time and patience.

From the graphs I've seen of most FR drive units, they screw up the midrange b y themselves without the help of any crossover electronics

 

Graphs, always graphs, dont you have ears, thats what people use to listen to music, not graphs... :newbie:
