Scan Speak multi way speaker

[the_cantan]

Hello, I wanted to make the cabin in this url link. DISC-4 however, crossover values are absent. these are the speakers I have.

Tweeter

Troels' kit without drivers is not that expensive at all. You are on the wrong path.

 

[the_cantan]

Dear @Lojzek thank you.

 

[Lojzek]

The problem is that you are basically seeking a modification of the Troels' design and yet no one can do that unless one had all the parts acumulated and performed the whole design process, obviously for free.

Your tweeter and midrange are quite different from Troels design, therefore the filter will also be different. Check out his FAQ: DISC-4

No, you cannot use any other driver than those specified.

Absolutely right. I am aware. so would you suggest me a good online crossover design site?

Best regards.

Yes true. I will also switch to new cabin design and crossover design. what would be your advice?

Online crossover design rarely works. You need measurement equipment, simulation software and some time. Otherwise it would be a wast of money on those expensive drivers.

That will invalidate the Troels' crossover even more...

My advice would be, if you're new to this and don't want or can't spend the extra time to get the experience and knowledge and some extra money on the tools, to just go with an existing design and follow the instructions to the letter. If you are willing to put in some more effort, be prepared for a rollercoaster of failure, learning and success. Definitely rewarding, but not everybody's cup of tea.

yes, your first (or first several) speaker builds should be an existing design... There is so much you will learn from constructing a proven design.

I suggest you start reading this forum from beginning to the end and get a book on loudspeaker design. After a couple of years of studying you will see this matter in a completely different way, enlightened.

You have a set of drivers to make two pairs of speakers, not a coherent four-way.
Read AllenB's Making Speakers Without Measurements article, then try two separate projects, the 22s and the h26s as a conventional two-way, and the other 8" and the ten as a low-crossed two-way(called WAW or FAST).


Both can work, they have different in-room behavior, and you could learn a lot about what works in your rooms with these to compare.


These are drivers that you can use in many builds as you learn and find ideas you want to try, but they are not the easiest to work with, so be patient and it will not be money wasted.


Have fun!

For a first time build, go with something less complicated than what you propose. And definitely go with a kit. Parts Express tech forum is a good source of the kind of information you need to get started in the right direction. Speaker building is fun and challenging. Just don't try too big a bite your first time out. That can lead to frustration.

 

[the_cantan]

Thank you very much everyone.
Are thiele small parameters of existing speakers not enough for a new design?

regards.

Manufacturer's published specs could be used but only as a last resort. If you're going to sink a lot of money into Scanspeak drivers, you aren't likely to get the best results using factory specs. Instead, each drivers' T/S, impedance, and spl curves need to be measured, in the enclosure they're going to be used. Then plug them into a crossover design program like these:

[buggers]

No. You should measure the drivers yourself, which again should be pointing you towards building a proven design for your first project...

thank you so much. I think this is longer.
