I have 2x100W 2" tweeters and 2x40W 4" car loudspeakers.
The speakers almost take the entire face of the box.
Car speaker:SPL: 86 (dB/2.83 V/m)Tweeter:Sensitivity (2,83V a 1M): 108dB max. (0dB = 20µPa);
Ok, so I have here the 2-way crossover calculator.http://www.diyaudioandvideo.com/Calculator/XOver/Which value should I supply the frequency in hertz?
Another thing is that there are dozens of crossovers types... which one would be the probable best bet?
The driver attenuation circuit goes only for tweeter?
Would it be placed before or after, or in series with drivers?
Power per channel is the max power written in the driver specs? Not the amp?
Obviously it has to be in the drivers' overlap range, so somewhere between 5 and 8 kHz.
Didn't you try out the calculator? It draws the circuit.
The attenuation circuit will basically take away some of the power sent to the tweeter and dissipate it as heat through the resistors.
The only reason you have to enter the power is that the calculator will give you minimum power ratings of the resistors. Actual power ratings may (and should) be higher than that.
I read on that site that uneven orders are the recommended (so it would be either 1st or 3rd), that would avoid the polarity inversion trick.
It comes to my mind now that the box is sealed. And I just read the words heat & dissipation... It is not that I need ventilation, right?
Ok, so we have these 1W or 2W resistors which are huge... we're talking about those, right?I entered 20W per channel, based on the amplifier power... I am not sure if I have done this right. However, I see weird results like one resistor being 18W. A 20W resistor would be the huge squared porcelain resistor. Is this more or less the deal?
I am projecting a small pair of loudspeakers.The use will be with a computer. Perhaps with an amp of 20W inbetween the two.I have 2x100W 2" tweeters and 2x40W 4" car loudspeakers. Brands are good enough. The enclosure is about 220mm (height), 142mm (width) and 143,8mm (depth).It will be constructed with 9mm MDF.Big question right now:Do I go for the sealed design or do I go for the ported design?I already know the pros and cons but I heard that some are particularly better with different kind of application.Please answer ASAP, because I will be finishing the CAD models tonight and tomorrow I have to hand over the cabinetmaker.
I still don't know if I need to take the tweeter here into account
f not, you will probably have a problem with back pressure from the bass/mid affecting the tweeter membrane
Car speakers are designed for cars.
