AN drivers are known to be shouty on the first 100-200hrs, after 300 hrs, bass will show its true color, mids will be tamed and the highs will be detailed but not harsh, I experienced the same with my AN drivers during the time when they were still new.

Very True indeed.

While still waiting for the emblems, I have plenty of time to listen to this pair and probably do some tweaks, if needed still. If you're near Pampanga, those interested may come for a listening session.

Nice craftsmanship. If this is down firing, the clearance from the floor must be 1.5" minimum - 2.5".... It has effect when the clearance from the floor is adjusted.

The height of the footers can be adjusted so no problem here.

Sir Larry,

I have seen personally your speakers in the so many hifi shows I have attended. I have personally listened to them paired with Erik's amps...and all I can say is WOW! Genuine Talent! Excellent Craftsmanship! Hope you can post videos soon here...CONGRATULATIONS!

Bro nung una, medyo prominent ang hi-mids. Medyo kulang sa bass (I experimented with placing the port at the bottom as requested by owner). Gagawa na sana ko ng bsc at zobel pero sabi ko try ko muna tweak ang port before doing anything electrically. Where before butas lang ang port, I decided to extend the port. In conjunction, binawasan ko ang stuffing like the thing I mentioned in the previous post. May bass na. Tuneful bass. I'm using a 2A3 SET amp, btw, with an aikido preamp playing spotify.

PERO, medyo may slight shout pa. Again, naisip ko kaya pa rin masolve ito mechanically. And mukang tama nga ako. Tried something with the dustcap, temporarily. I will measure later to see where the peak is coming from pag tapos na tapos na ang box.

Very transparent at efficient ang AN. Effortless sa SE 2A3 amp. Actually I am surprised na kahit walang whizzer cone, extended ang highs ng Classic.

The tweaks/suggestions of TNT Audio might help..

Jun eto na video. I have done no further changes to the cabinet except inserting a passive equalizer made by Tony in the chain. Problem 'shout' was gone. If the drivers are fully burn-in, then maybe the passive equalizer is no longer needed. I used Wendel's vintage fisher tube amp currently with me as the test amp with the tone controls set at "0".

nice to know Larry, i had my doubts when we were testing that passive network....
did you use an RTA to make adjustments?

I only used the audiotool app in my android phone and I don't see any abhorable spikes in the response. It's entirely different than when I last listened to these speakers with a friend.

con su permiso, camoteque....link to baffle step correction....by Paul Joppa
http://www.t-linespeakers.org/tech/bafflestep/passive-BSC.html

you can ask your friendly cable maker to make one for you, it is very easy to make
and has been proven to reduce "shouting" in the audio nirvana FR speakers....

should you have further questions, feel free to ask....

since most pre-amps/buffers/sources will have source resistance in the
neighborhood of 1k and power amps' input impedance more than 50k in most cases...
just two resistors and 2 capacitors are all you need to implement this...

this are recommended values:

Quote

Rsource < 2k ohm
R1 = 10k
C1 = 1500pF
R2 = 12k
C2 = 0.033uF
Rload > 50k
Cload = 200pF

Hi Tony,

How can this used for an existing AN speaker system? Is this still necessary with my present system:

DIGITAL SOURCE -> DAC -> Tube Pre-Amp / Phono Stage -> SE 2A3 Amp -> AN 12" CF Speakers (with Larry's Cabinet)
ANALOG SOURCE -> Tube Pre-Amp / Phono Stage -> SE 2A3 Amp -> AN 12" CF Speakers (with Larry's Cabinet)

Thanks,

Teta

if you are experiencing "shouts" in your mids/vocals as they call it, this will help,
otherwise kung okey naman ang mids mo, then no need na...so case by case basis,
you may or may not need this...

I noticed a definite improvement when I switched back to my Sovtek 2A3s from my Psvane 2A3Bs. I think the Psvanes over-emphasized the mids - hence, the "shouts". Aside from the lessened shouts, I noticed that the sound seems fuller and rounder with the Sovteks compared to the Psvanes. Also, the subtle pops / crackles from the Psvanes disappeared with the Sovteks. Then again, that's just me and I could've been just imagining things.

Atty. Teta, I may be wrong but could it be "break in"?
