If you can audition and compare them, then you can base your choice on your own judgement. I will say I used to sell Polk Monitor 7s in the mid 80s, and those appear to be replacement tweeters…Polk replacements, but not the ones originally used, which had black fabric domes with a small hole at the apex. The Celestion model is not one I’ve seen before, but looks as though it might be a lower end series sold through retail chain stores, and therefore not the best of Celestion quality. The Dyna A35 is a bona fide classic, made in Denmark by SEAS, and loved by all. I would choose those.
