Single way or multiway

I’m a speaker builder with extensive experience working with Tang Band 8" drivers. One of my designs is the Tribeca-001.

I'm not familiar with your specific listening standards, but to avoid harshness in the high frequencies, I found it necessary to remove the whizzer cone. The whizzer tends to exaggerate the treble, especially when paired with certain tweeters.

In this setup, I integrated a Fostex tweeter for better high-frequency performance. Using an RTA program with measurement microphone, I confirmed that the whizzer cone was introducing too much energy in the upper range, which negatively affected the tonal balance. Removing it resulted in a much smoother response.

The whole point of the Tang Band 8" is to use them as full range speakers.  They do measure with an up tilt in frequency response so probably best listened to flat against the wall instead of toed in. 

Still, we all hear differently.

@bache We're on the same page with whizzer cones! They are far more likely to have breakups of their own. I tried to find a version of the driver that didn't have one but as you know, to no avail. I don't play those speakers very loud and my crossover rolls the highs out of the Tangband (to help keep a nice impedance curve) but I've not had the guts to go after the whizzer. How do you do it? That strikes me as very easy to make a mess of it!
