ALK Crossovers - For Sale

[Deang]

You can't "measure" with your ears.

There are innumberable ways to design a filter. Parts and design change the signature of the speaker. Just because it sounds different than you are used to hearing, or doesn't appeal to you -- doesn't mean the network is "wrong".

The impedance characteristics of the new filters are relatively benign compared to the older designs. Also, the new filters incorporate a bandpass on the squawker which I consider to be an absolute must with the stock horns.

My AK-4's came with boards utilizing point-to-point wiring, later Klipsch went with PCB's. What you have is not a prototype. In the end, it is the acoustic response that determines if something is "wrong" or not, and I haven't heard anything from the new designs that would indicate they are poorly designed. The sound is not as transparent and grain free as I would like it -- but they sound very good in their own right.

My ears are happy with the AL-4, but what do I really know?

Hundreds of albums and not a single test record in my collection!

I guess it is time to get a test record (vinyl style) - I also have a new turntable coming in a few days so I might be due.

For those who know and have a preference, what is your recommendation for test LP?

I have seen a few online but never owned or used one.

I'm thinking of the ones with sweeps and tones and channel tests, frequency tests, resonance tests, tracking tests, etc.

I think you get me wrong !!

First , we both use our ears from the beginning.

So i found out there was a serious problem in the acoustic output .

Not just a matter of taste or what i like.......

The measurements which had been taken place shows a serious problem in the crossover between

squaker and tweeter. The squawker is rolling of at 3000 Hz and the tweeter comes in at 4800 Hz.

And way to loud. The impedance load in that range is 20 Ohm.

I bought mine La-Scala's in 2002. They arrived after six month in march 2003.

After a while they went back to the importer because of a problem with the "doghouse"

assembly , network failure and one driver (K-55-x) didn't match with the other .

The importer changed mine La-Scala's with his.The second set was better build.

But still "sounded" in a technical way not good.......

I went my own way and found a serious speakerdesigner .

He run some tests after i took the speakers to his place......

The AL-4 which i have is on a chipboard and point- to- point wiring .

But it could a lot better assemled and soldered.

I still believe the design isn't that good.........

You can't get a smooth output from a horn loaded speaker design.

Sure, it is always a bit rough and the frequentie responce is never nice and flat .

But i think it is acceptable the way it now is.

Have a Nice Christmas !!!

Dean,

It is Christmas, and i wish you and all the others a Nice Holliday !!!!

When i read mine answer back .

It was a bit a shock when i saw the red letters .

It looked almost in negative way and didn't mean it that way !

We have had this discussion before.

Maybe i can send the AL-4 over on mine costs ??

Let me just now .....
