help to calculate box please

[ricardo munoz]

Hi, I'm Ricardo from Chile and I need to ask for help, I want to make a 2-way system with my speakers (they are car), and I tried winisd but I don't understand the program much, I need to know what would be the optimal measurement for the speaker,I will leave your specifications. the other question is if I can use the crossovers that come in the kit or do I need to make exclusive ones for these boxes?, I hope you can help me, greetings.

Your attachment doesn't work.
Perhaps you could tell us the Brand and model of your speakers?
(& if possible, a link to the data sheet)

leave a link of the model,thank

The Elate SW 6 is a car mid/bass driver which would suit a sealed enclosure.

I would experiment with strong cardboard boxes of 30 to 40 litres in volume to see how the driver performs in them before committing yourself to actual woodwork.

It's not a subwoofer really, having a highish free air resonance of 50 Hz, and I wouldn't try to tune it in a ported enclosure.

P.S. I would use the supplied crossovers.

thanks Galu for your help

P.P.S. PeteMcK may disagree with me and come up with a ported design! 🙂

With qts 0.44 you can do enything, sealed and ported even tl, I would go sealed in 20/25l. Nice midwoofer.

P.S. I would use the supplied crossovers.

being optimized for car use I suspect the baffle step may not be considered ...
but of course it can be a starting point

 

[Galu]

I was trying to keep it simple, stv.

Would a wide baffle provide compensation?

I would go sealed in 20/25l. Nice midwoofer.

The specifications you attached are not the same as the ones supplied by the OP for the 6" woofer, but there is room for experimentation regarding the volume of the sealed enclosure.

@ ricardo munoz, will you use this by itself or will you have other speakers?

 

[ricardo munoz]

I just got this, and a supreme morel piccolo treble set

I can confirm that the above are the correct parameters.

 

[aperiodic]

Crossover 1800 hz which is little low for the tweeter, but I would keep it as it seems to be 12 db/oct and well made, air core inductors etc.. In car you are in near field situation. Just do not push it all night long.

 

[Galu]

being optimized for car use I suspect the baffle step may not be considered ... but of course it can be a starting point

Just a thought - the crossover has an alignment system which should prove useful.

The tweeter level can be adjusted.

The tweeter and woofer crossover slopes can be adjusted.

[aperiodic]

I may be wrong. The owner probably have more reliable information about driver parameters. Anyway if qts 0.33 -sealed.

@ ricardo munoz, will you use a subwoofer?
