Hey, I know that Bob Crites showed the frequency response curves of its A-55G and the Atlas both tested on a K-401 horn,
And I also know that they ran a distortion test and is shown a 4db improvement in THD beetwen the A-55G and a two piece phase plug K-55V.
However I'd like to read some opinions from someone who has heard or tried both. Thanks.

Not sure what a Fostex H400 goes for, but the H200 is CDN $5200 a pop!

TAD is a brand of HIFI equipment ----
I didn't know.. Anyway why do to think that Fostex horn can match well only with a TAD driver?

Sorry , but I do not see the A-55G to be in the same league as a Fostex H400 - this is really meant for a TAD driver
Sorry what is a TAD driver?

I'd like to cross the A55-G at 6-700 Hz, so I'm thinking to use a horn which have a Fc of 450Hz, is a Fostex H400.

What do you think? Thanks

I do not know the Fc of the K61 horn but it is lower than a K600/601 due to it's larger mouth size and length. Don't forget many horns are used to below their cut off, consider the K700/701 has been used by Klipsch with a 650 Hz crossover and it is a much smaller horn. Remember also that for best performance the rule of thumb is to cross over an octave above Fc.
Thank you, I suspected that I have to cross around 200Hz above horn Fc to get best performance, I suppose because to avoid getting outside a nasal sound from the horn (?).

Me no, but Dave A yes, he compared B&C and Faital, a priori he prefers B&C DE10 for Chorus II
Okay..does he prefer B&C DE10 for Chorus II because there is no need of l-pad attenuation on its crossover?

@Dave A replied above, B&C DE10 best tweeter on Chorus II, let's trust his expertise.
I see that. Anyway have you ever tried Faital pro HF?

The mid horn used in the Chorus 2 is a much more modern horn design compared to a K600/601 (metal and resin) horn(s) it is a hybrid conical throat then a Tractrix flare and it is a larger horn which means it can hold it's polar response down to a lower frequency resulting in improved image, it is the horn which Klipsch designed to replace the K601 after they dropped the Cornwall and replaced it with the Chorus (Chorus used the K601 I think) and the Chorus 2 upgraded to the newer improved horn. Remember the K600/601 is a very old horn design.The mid horn from the KLF20/30 is and even better horn in that it is capable of much wider response it can be used up to 20KHz and it is also much shorter which means you can better align with your woofer and that's a big deal. I hope this helps.
I get it, what is the cutoff frequency of the K-61 horn?

Hi all,
I wonder if anybody has modeled or tried the Faital Pro 15PR400 in a LaScala / Belle / FH1 type bass horn, and how it compares to K33 and to Eminence Kappa 15C?
Have you tried the 15PR400 at last?

For what purpose? The K-61 midrange horn on the Chorus II is already a step or two above the K600 horn in performance.
I'd like to try the A55-G with a K600 horn... croossed at 600Hz to 6000Hz.
Can I know why do you consider the K-61 horn one or two step above the K600?

Non so come siano stati utilizzati i miei altoparlanti prima, ma come dici tu, ci sono possibilità di altoparlanti per bassi usurati. Non cerco l'approvazione della comunità, ma cerco persone che abbiano esperienza con le modifiche ai loro altoparlanti. Pertanto, è bello se qualcuno vuole o ha apportato modifiche.
Have you tried any Faital pro woofer at last?

@JeffLebowski Fezz Audio makes the best sounding tube amplifiers under 5-6000$ imho..
Anyway Unison research makes some good tube/mosfet amps, but Audio Exclusiv is even better for this kind of hybrid amplification.
No interest in saying this... trust me, just tests made at my own expense.

Fezz is so interesting to me. Polish made. Kind of like a big family with commitment to a good product.
Also, priced reasonably.
I think this is something to look at OP.
Cheers
I think that Fezz Audio is one of the last few solid tube amp manufacturers left in Europe.
Little show, lots of substance.
Greetings from italy.

If you're looking for that "bigger" sound of the larger Heritage speakers you need a bigger horn. The Tractrix horn also has a more "open" sound than the smaller exponential horns. The stock Chorus II style horn is larger than the G700 (600hz vs 700hz) and Tractrix so the G700 horn would be a step down in my opinion.
I get it. Rather, what do you think about using the A55-G driver with Crites C600 midrange horn always mounted on a Chrous 2?
Thanks

I need tube amp recommendations for my new Forte iii’s, at least 20 wats per channel, new or used.
budget is $2000 or less.
I’m using a BAT tube Vk-3ix preamp (with six pack upgrade) with a Parasound A21 amp now.
Look at this dude, amazing value for money imho.

with the CF3/4 horn the option to go two way is available provided you use a wide band driver and a two way network. one could modify a CF3/4 network.
further if you wanted to upgrade this as a three way then the K79 tweeter horn could be replaced with a KLF20/30 mid horn (it is also a wide band horn) that way your mid and tweeter diaphragms would be in a much better alignment with each other.
3 hours ago, jjptkd said:This set up right here is easily the best sounding pair of speakers I've ever owned especially now that I have upgraded the tweeters with the de-120's.
Honestly the step up from the stock style threaded horn to the CF-4 horn wasn't as big of an improvement as swapping the drivers were or as big of a difference as between the Chorus 1 horn and the CF-4 horn. It was a slight improvement but not sure worth the effort and destruction of the cabinet in that way to recommend anyone else take that plunge.
My advice would be to get a set of stock k-61 style horns with the threaded inserts and attach the A55-g-- that is a simple bolt on swap that is easily reversible and a very nice upgrade.
What do you think about using the A55-G with the Crites G700 midrange horn mounted on a Chrous 2? Any thoughts?

Two reasons why this won’t be a good choice.1) It’s Chi-Fi and that should give anyone pause. I know there are some good Chinese companies out there and this may be one, but proceed with caution.
2) This is an integrated amp with no direct input. The OP already has a preamp and didn’t mention looking for integrateds.
Shakey
Fezz Audio is Polish and there is Titania Power with direct input. Check out before talking.

Questi sono completi e suonano molto, molto belli! Avendo ancora alcuni problemi con la copertura della griglia, dovrai lavorarci sopra per farli sedere bene.
Of all the horns you've tried on your Chorus II with your A-55G drivers, which one do you like best? What are the differences you've found between this horn, forte III horn, and chorus II stock horn?

Hello Deang, did you replace the diaphrams in his solder terminal dual phase plug K-55V's and compared them to the John Allen's A-55G's?
