Tang band W8-2145 need to attenuate mid to high

[supernut]

hi

Can any one suggest crossover for Tang band W8-2145 to attenuate mid to high about 3-5 db? from 1,000 hz - 20,000 hz

I like BBC dip and attenuate high. Can anyone help me design crossover for this full range driver?

Thank you.

I have same speakers.
Have you built these?
How deep is it playing?

Sounds like all you need is a baffle step filter. Without an RTA plot it's a guess, but you might try 1.5mH||4-8Ω.

Yep, try an inductor in parallel with a variable resistor as an experiment. There are some online calculators that can give you a starting point as far as component values and attenuation levels: Loudspeaker Diffraction Loss and Baffle Step Compensation Circuits

Here is an example of what Bob is referring to with an inductor in parallel with a variable resistor, though it is for a different driver: Full Range

You'll need a mic and some measuring software (REW works well for this purpose, as does an old analog Radio Shack SPL meter, and a tripod). Pick up a few values of coils and then experiment with the coils and the resistor. This will allow you to tune your speaker to taste. It'll take some time, but you'll learn from the process.
