3 Way Eliptrac Horn Klipsch La Scalas

[henry218]

looks like a great experience

[Full Range]

I remember that I promised earlier and I quote

I have had an offer from a fellow SNAer - thanks @green-wagon to build the crossovers for me for a small cost and the promise of getting that " weak in the knees feeling when he has a listen on the system when it's all connected up

I was happy to oblige with coffee & music @greenwagon and you are very welcome

Surprisingly when you arrived you said woo an Irish Terrier & would be the only person that got it right - they are certainly a great dog. The IT breed has been part of our family for about 30 years

Compliments to you as the crossover build was to my requirements and worth every penny spent on them

As you noted - the fine tweak stage has started and when finished, I would die happy knowing that I have lived with a system that when turned on Audio Nirvana fills all my senses

See you back soon

Inductors may interact with each other in this orientation.

[Green Wagon]

Its good to see someone that actually pays attention and cares about such things.

 

But any interaction should be minimal.

the closest ones are ~12cm apart, and thats between the small mid and tweeter ones.

These are going to be 'upgraded' to ones that should have less interaction than the current ones.

 

what you can't really see from the pics is just how BIG these are.

The plate is ~50 centimeters long, from terminals to the large inductor end.

That black duelund resistor is 13cm long

 

The large inductors are (from memory) 18cm apart.

 

But if you really want to worry, those red caps have a aluminum 'shell' that if placed in the wrong spot also create issues.

And then theres the attenuator transformers to consider with there iron cores.

 

it was all carefully considered i assure you.

 

yes there will probably be a little interaction, but i suspect it'll be so small as to be of no real consequence.

 

After hearing and seeing the 'professionally' made original units, i can vouch for the news ones superiority...

 

Maybe FR will put up pics of the ones he was using before these.

[Full Range]

The original crossovers that came with the speakers were

ALK universal

These we're going to be stripped to salvage parts to make the new crossovers

In the interim I used the

ALK Gentle Slope Crossovers ( a two piece system )

The ALK universal crossover parts extra parts purchased and coils were combined to make the new crossovers

The inductor coils are over 1.5 kg each

FR,

if you want to sell those jantzen super caps let me know

and the litz inductor too if its the right values

cheers

I was going to make a list and place them for sale

However I can PM you the list Henry to see if the items match the values you need

thanks mate

Full Range: magnificant build. Good work. Any idea of the effeciency? I have a few 2.5W and 6W SETs that would love to meet your speakers.

If the circuit has been designed with the inductance of the components in their actual location.... then there is no problem.

Mark it's a minimum of - 104db

[Full Range]

I have been testing the crossovers - giving them plenty of burn in time, and have found them so agreeable that it takes my wife a crowbar to get me to get up to eat

Sound is beautiful at this crossover point @ 500htz for this setup combination

Myself and @greenwagon - the builder of the crossovers, have given a score of 9 out of 10 on both tone and music tracks

Over the next month I will tweak the crossover minimally to get the very best out of the crossovers and the speakers

We will be replacing or changing over some resistors and coils to enhance the sonic signatures of the individual drivers

I feel and hope that these tweak additions to the crossovers will take the La Scalas to another level and then I will sit and enjoy the music forever more ( famous last words )

Changes planed are

1) Pathaudio earthed Resistors to the tweeter section

2) Mills Resistors to the tweeter PCB

3) Duelund standard Resistor

4) Jentzen flat wax Inductor Coils to service the mid and tweeter sections

Just taken a short video ( hope it does the system justice )

Frames on the crossover boards have not been completed yet

I'm not sure how much more can be squeezed out of your system.

Its at a level that is above mortal realms.

 

Therein lies the problem.

After having just finished new larger cabinets for dads jbl's, 

I'm now at the point of looking at capacitor, inductor, resistor upgrades for his xovers.

Unless I do a whole new xover to start with.

 

I blame FR for this. *shakes fist angrily*

I know your father really liked the La Scalas when you visited with him for a coffee and a listen

So I did you a favour - as now you know the sound signature he likes

[Green Wagon]

He really does like your speakers.

 

In many ways they are almost brothers.

both have 15", horn mid, loaded tweeter, high sensitivity.

 

i think with the jbls new home, there fairly close to yours.

swapping out caps, coils, resistors, i think will make the difference closer still.

 

Will be interesting to see what your thoughts on them are.

Here's an interesting weston electric horn on top of a la scala bass cab...,pretty cool.

On that note- Why do we have a love affaire with horns

Here is a BBC story and video on the Denman Horn - http://www.bbc.com/news/uk-27483035

Now that's a horn that is big in size and still produces superb sound

[Green Wagon]

Um, dont all men have a love affair with their porn horn ?

Update

While Im waiting for the new resistors to arrive I have kept myself busy by making new hookup wire looms to connect the three speakers to the crossover

Wire used is Kimber 8TC ( 16 strand - 8 strands each for positive and negative )

Tinned ends with Silver / Gold solder

Heat shrink black / red for visual ID

Then added pure copper gold plated rings and soldered again. These rings have made a very secure connection on the speaker & crossover terminals, with no likelihood of any looseness causing bad connection if the future

Name labels for identification

Very satisfied with my handy work so far

Some photos

i guess the next upgrade is CMC copper binding post

i guess the next upgrade is CMC copper binding post

Next is the box frame on the crossovers and the resistors

And that will be it - I will be finished

The La Scalas are sounding so nice now that it's hard to leave the sound room for fear of missing out

I get music fix withdrawal symptoms

[Malcolm]

i guess the next upgrade is CMC copper binding post

Get rid of the connectors and hard wire  .

 

Cheers

[henry218]

Get rid of the connectors and hard wire .

thats my MO

I would have hardwired if the crossovers were internal

Furthermore all the internal connections are hardwired from driver to connector

But what I have devised is next best thing for a secure and solid connection to the external crossover

You know by that pic your cm away from hardwiring
