Avantgarde & Audio Research


Recommended Posts

A completely new direction for me, so I'm starting a new thread.  Adding this to the old thread did not make sense. 

 

Said I'd stay away from valve pwr amps; and had reservations about horns, but stuff comes up and I made a change to what I never envisaged.  It sounds good, but still more changes to come.  

 

From Magneplanar 20.7 to Trio XD.  From AVM MA 8.2 to AR Ref 160M.  From Koetsu Onyx to Ortofon MC Anna.  The Onyx had a low output resulting in the phonostage running out of gain on the MG20.7.  The MC Anna has even lower output, but luckily the change to Trio XD gives me plenty of gain to easily cover the low output of the MC Anna. 

 

For over two decades I have not been happy with my analog set up.  It has under performed.   I think I needed to use a step up transformer for the Onyx and have the Onyx retipped by Koetsu.  With the MC Anna I love my analog sound. 

 

The Trio is not flat to 100hz.  The REL does not go much above 120hz.  We have a problem Houston.  No midbass in the current setup.  I've been moving the subs around, but there is no cure for component limitations. (See Later, I changed Trio setup).

 

These pictures are ugly, but I'm an audiophile not a bloomin' home decorator. 

 

The setup is Ortofon MC Anna on Graham 1.5t on Aura tt.  AR ph8 phonostage. AR Ref 6 preamp. AR Ref 160M pwr amp. Trio XD maiin speakers. REL 212se subs.  Cables are Audioquest and Synergistic Research.  Two dedicated 20A circuits and 2 dedicated 15A circuits.  Custom fuses on any component that needs them.  They do reduce noise floor.

The subwoofer will be capable of much higher frequencies than 120Hz.... if the electronics will allow it.

 

 

I thought there might be a chance that your subwoofer bypassed it's crossover (low pass filter, which can only be moved up to 120Hz) if you used its LFE/.1 intput

 

.... so I looked in the manual.      To say "the manual is unclear about this" seems a comical understatement.

 

Give it a go and see what happens (if you haven't already).

Looks great @GroovyGuru.

I like the Avantgardes.

Was always curious to hear the high end Ortofons.

 

I'm surprised about the Trio's only going down to 200 hz, I would have thought they'd go a lot lower.

How do Avantgarde go about running these speakers?

Do they run separate woofers?

Avantgarde subs don't go very low, but they do go into the midbass.

It looks like you can use the bass section from the Uno and Duo's too. Maybe they cover it all? Surely Avantgarde wouldn't leave out a section of the spectrum?

Yes, the Trio needs to be paired with Avantgarde subs.  I was hoping the REL would cope.  It doesn't do a bad job.

I have MC Anna on a Helix 2 with Schroder CB arm.  It is some kind of magic...

I think trio goes down to 150 and up to  20k hz. I am told the three horns blend together better than the duos which I have.

rel goes up to 150 I think. I’ve tested with the model below the 212se.

tuning is gonna be a *****.

ag subs will recommend a selectable range from 60 to 150 hz for matching the trio.

I’d recommend you get some herbies giant gliders for the subs and the speakers. Will give you more clarity and make it easy to move those heavy things around. Which is probably the most difficult thing to do while tuning given the weights. 
At the same time get some herbies tube dampers for your ref6. They will increase clarity as well. 
Immediate upgrade and no burn in time required for both.

I downloaded and read the through the 212SE subwoofer manual as well and the only thing it says is that the crossover can be set anywhere from 30 to 120Hz. It says nothing more, nor if there's a way to bypass the crossover entirely. 12" woofers should easily do up to much more than that so it is purely an electronic limit unfortunately. Perhaps they know the quality of frequencies those woofers reproduce above that range isn't ideal. My 16" subwoofer goes up to 230Hz with the crossover disabled, but the sound quality from that woofer above 80Hz is pretty bad.

Yes, the upper limit on subwoofer crossovers as determined by the quality of bass above that frequency.  You want quality not just quantity from subwoofers, otherwise they are a rubbish product.  In fact REL don't even like the 212se at 120hz.   

 

For some reason, people seem to think I'm getting bad sound and I need to rearrange setup.  For the record, I'm getting good sound and don't need to do anything but pair up with a higher reaching sub.   I set up the Trio first, to get maximum bass from it.  Then I set up the sub, which is the way to set up a system.
