Smile Need recomendations for 3-5" midrange driver?

I am looking for a midrange driver to comlete a cabinet project. I'm looking for a driver that aproximates the following specs as close as possible. 3" to 5" driver @ 8 Ohms, SPL as close to 89.3 as possible with as flat a frequincy response range between 2500HZ through 4000HZ as possible and with as flat a resistance range between 2500HZ through 4000HZ as possible.

Not asking for much am I?

For that kind of range might a dome midrange be better? Something like the Morel MDM-55 fits your required spec quite well, may need some attenuation. The Monacor (TangBand clone) DM-75TB could work if it must be 3" minimum, but needs more padding.

If you prefer a cone, the Seas MCA15RCY might work. It's quite large to cross this high though.

Do you mean 250 Hz -- 4k? (Fostex FE103 would be good)

2.5-4k would be a tweeter.

I mean 2500HZ-4000HZ. I'm trying to match it to an Adire Audio AV-8 in a 4 way speaker project. The AV-8 gets crazy above 2500HZ and my soft dome tweeter wont reproduce that low. If I were not this far in I would go in a different direction. I'm over budget as it is. I guess what I am saying is I'm stuck, please help!

That's less than an octave working range. Finding a driver is not too difficult. But to get decent integration with the other drivers over such a narrow band is going to be really difficult in my experience.

You will have to be really careful to get each overlap working, it will all interact in an area where your ear is incredibly sensitive to phase issues.

You can't make it a three way? It would just be really hard then

Hey Bill,

You might want to check out the Vifa D75MX-41-08.

You'd be better to get a tweeter that will go lower, or if you insist on a 4-way, the AV8 is probably best XOed below 1kHz. I'd XO them below 400 Hz.
