[Cornscala III from Italy & Oppo BD 83 SE Modifications]

Hi guys...how are you???

Cornscalas sounds very good after some years....

I just bypassed the autotrasformer on the CT125 in my absorbent room and I continue to listen with grilles on.

Just perfect for me!!!!

Thank you again!!! ;-)

[Horn in angle from Italy: triangular section ???]

Thanks for sharing those very very interesting documents !!!!!

I'm going to read all !!!!

I'm a novice and I'm surprised that La Scala bass horn is "exponential". I supposed to be conical because the walls of the horn are planar (!!!!?????!!!!)

See you after my vacations (without internet and computers...) in 10 days... ;-)

I've to study a lot :-(

[Horn in angle from Italy: triangular section ???]

@WMcD: Ok WMcD, I'll wait you infos!!!

@djk: before start with software I'd like to understand the theory.... ;-)

[Horn in angle from Italy: triangular section ???]

Thank you WMcD !!!!

Here my spreadsheet.

I can't understand the formula for the lenght of a conical horn on the link above. (T=infinity , ecc....)

Could anyone post this formula???

I'll put it on my spreadsheet.

Thank you again!!!!

[Horn in angle from Italy: triangular section ???]

Let's speak just about CONICAL horn.

What is the formula to calculate the lenght of the horn???

In the link above I see just the sections (throat and mouth) but not the overall lenght of a conical horn (in the case of T=00).

I've already calculate:

1)Sections

2)Back chamber

3)Compression chamber

I need to calculate the lenght.

Thank you guys!!!!

I'm a novice so I'm trying to divide the problem in several little problems...to be solved separately.

[Horn in angle from Italy: triangular section ???]

Hi guys,

some years ago I've built a pair of Cornscalas, here the tread:

Now I'm looking for a simple and big basshorn.

The following design it's OK ??? (Conical horn with triangular section)

To calculate the dimensions the following theory is OK???

Thank you in advance for your answers and sorry for my written english!!!!!

[Klipsch R3650 vs Klipsch SCW3]

Many thanks guys!!!!

I'm going to install the R3650 in a very thick wall (near 20") made by rock.

So I would ask: what's the correct volume that I've to use for the best sound????

I've to use some damping stuff in it????

[Klipsch R3650 vs Klipsch SCW3]

I'd use a center that best matched the sound of your main L/R speakers. R3650 is Reference series compatible.

@colterphoto1: according to the compatibility with the Reference series do you think the R3650 is better than SCW3 ???

Even with a smaller woofer???

[Klipsch R3650 vs Klipsch SCW3]

Given my room constraints i have to use in wall speakers (front, center, surround).

I have the opportunity to buy R3650 (new 6,5") or SCW3 (old 8") at the same price for front.

What is better as front channels?????

What I have to buy as front channels??????

Thank you !!!!

[Klipsch R3650 vs Klipsch SCW3]

new 6,5" vs old 8" : what is better as front channel?????

[Cornscala Build... A, B, C, or D?]

I've already built my Cornscalas (with the old Bob Crites stuff: PH800 horns, CT125 tweeter, etc...).

Here my building 3d:

http://forums.klipsch.com/forums/p/125302/1267426.aspx#1267426

Now a friend would build another couple.

So, if I well understud, the best (regardeless to cost) is the Eliptrac 400 + Circletrac HF combo.

The best value for money combo is the Bob Crites Type C.

I well understud???

Sorry, but I can't speak american. ;-)

[Cornscala Build... A, B, C, or D?]

Good morning (in Italy...),

do you think the combo Eliptrac 400 mid horn + Circletrac HF (that you built also...) is better than Cornscala Type C or not???

Thanks in advance for your answer and for any other contribution !!!!!!

Roberto.

[Looking for Klipschorn ...]

Those I saw, was walnut color.

Could be painted by some owner...I suppose.

Any other suggestions?

Thank you!!!!

[Looking for Klipschorn ...]

Hi guys,

sorry for my bad american, I'm writing from Italy.

I've already built a pair of Cornscalas (see :

http://forums.klipsch.com/forums/t/125302.aspx

if interested..).

Now I'm looking for a pair of Klipschorn for another house.

I've watched a pair having the following datas:

Type KCFR

Serial Number right 4K462

Serial Number left 4K318

I searched the following informations:

KC = no collar (What is means??? It's a good specification???)

FR = fir raw (It's correct??? It's a good specification???)

K = year production 1972, not sequencial numbers. (It's correct???)

The seller say that the woofers were upgrated to alnico klipsch woofer (he said "the best for klipschorn").

To better match those woofers to the rest of the speaker the old italian distributor replaced the old crossover with a crossover AK-3.

Could you tell me if those modifications are good or bad????

I've to buy or wait a better opportunity???

Thank you a lot !!!

[Cornscala III from Italy & Oppo BD 83 SE Modifications]

Ciao Herb!!!

Io sto bene e tu???

I'm enjoing a lot my cornscalas now !!!!

I'm working on the listening room. I put some diffuser panels on the wall behind the speakers. It's nice!!!

If interested I'll post some pics!!!

Another test I'd like to do is to not attenuate the CT125 (bypassing the autotrasformer).

Last but not least I'd like to test a OTL tube amplifier on my setup.

Thank you Schu !!!!!!!

[Klipsch One: Headphones for Ipod]

Good evening from Italy!!!!

I have some questions about the Klipsch One that in Italy are sold by Apple stores.

1)Klipsch define it "on-ear": this means "circum-aural" or "over-aural" ???

2)The cable (with the commands) is it detachable???

3)Are OK with the Ipod shuffle old version (the one without commands on it) ???

Thank you in advance for your support !!!!

Roberto.

[External Crossovers ???]

I don't know if ther'are audible differencies but I used external crossovers on my cornascalas.

They're decoupled from the cabinet by silent blocks.

With music the vibrations are present on the cabinet but not in the crossovers.

I think that's good.

;-)

[Round Tractrix]

Happy to see your development!!!

Thank you from Italy!!!!!

New power supply and new zero feedback, class A, discrete output stages (for stereo and front channels). By Aurion.

[Cornscala III from Italy & Oppo BD 83 SE Modifications]

New transformer for the Oppo output stages (By Aurion Audio)

[Cornscala III from Italy & Oppo BD 83 SE Modifications]

Hi folks!!! Are many months that I don't post here: how are you?

I tried many times to post some pics of the new Oppo cabinet but I can't. When I click on the "save" button my pc stop charge the page.

Is there any problems????

[Cornscala III from Italy & Oppo BD 83 SE Modifications]

Good evening guys!!!!

How are you?

I'm pleased to inform that my Oppo BD 83 - SE was upgraded on output stages.

Aurion Audio (the same that upgraded my Musical Fidelity A1) made some pure class A, no op-amp, zero feedback discrete output stages.

An additional transformer and an additional mosfet power supply feed current on those stages.

My Cornscalas sounds better of ever!!!!

PS Now I'm drawing a new cabinet for my Oppo.

It will be built with cherry wood on the sides (as my Cornscalas) and mdf on top and will be drilled on top to improve the cooling of the very hot pure class A output stages!!!!!!
