Hi all. I have a question regarding dipole drivers. Situation is I have a set of 2-way speakers with a low 1.5khz crossover. Tweeters are toast and no replacements are available. Having looked around I have found a ribbon tweeter that is a near perfect replacement. The only issue is it is a dipole design while the speakers are a sealed box. My question is what effect will the sealed box have on the tweeter response? I know there are a ton of variables so I don't expect a specific answer but more of a generalized one.... will it change low end response of the tweeter or it's power handling or efficiency? Since I want to use it in a sealed box anyway would it work better to seal the back of the driver? Thanks for any insight.
May we have make and model of the ribbon tweeter please?
Are you asking if you should seal the back of the dipole tweeter with a rear cup when using it in sealed enclosure containing a mid/woofer?
If so, the answer is yes, but enclosing the rear of a dipole tweeter in this way will impair its low frequency response.

Beston RT1002A Dipolar Ribbon Tweeter. Raising the low end response was my concern. The speaker in question is a Yamaha NS-30T. It is a 2-way with a 8" woofer and 1.5khz crossover in a sealed cabinet. Sounds like I am going to have to change the crossover to raise the frequency. As I recall, the average 8" woofer starts to break up around 3khz so I can raise the crossover point to 2.5khz and have more choices.
That's what I was thinking, but it would be nice to receive confirmation.
