2way Studio monitor with 10 inch woofer help

rhythmdiy · 16th December 2008, 05:59 PM

I am planning to build a pro studio monitor with the following drivers..

10 inch woofer:
http://www.tymphany.com/pl26wr09-08
Tweeter:
http://www.wavecor.com/html/tw030wa05_to_08.html
TW030WA05

I would like to know what crossover point suits best for this or do u recommend any other tweeter for this? but what about mids? can this 10 inch driver produce better mids? since its for studio monitor the user will be on near to 0 degree axis to the driver...

please give your suggestions...

Hi,

maybe i will be a bit heretical, but have you considered a BG Neo8pdr?
You can cross it lower enough (6-800Hz) and, in the "near field" you sure do not need a supertweeter. I have used it with excellent result,
a very nice planar and handle a lot of power !
That vifa 10"like low crossover point imho, no possible with a 1-1/4"
domes.
Just my 2 c.

Cheers,
Paolo

can u tell me one thing... I have a midbass driver with a heavy L-pad attenuation for about 7db but I just doubt how does it affects the overall performance and stability... I need to match the mid with the 10 inch vifa..

can u pls tell me as I couldnt find a proper guidance for this..

You say you want to make a studio monitor.
One of the main requirements is that it can produce large acoustic outputs with low distortion, this driver pair can do this with a crossover in the 1500Hz. region and a lower cut off around 40Hz. with a filter assisted alignment.
Ideally the tweeter would be waveguide loaded.

More details about your l padded driver are needed.
Part of the l pad resistance appears in series with the driver causing qt to increase, this can cause boom, which may or may not be a good thing according to the application.
rcw.

Rhytmdiy, you will have to padd the tweeter, not the woofer

You can expect a speaker with 81-82 dB /2,83v/anechoic with full baffle step compensation.
