They both have more smooth, gentle sound compared to their dome brothers. For unlimited budget project I would go 7000 with WG148R, but I can image to be happy with TW29RN. Tw29RN is good allrounder, no listening fatique. 7000 is more sophisticated, it has top end spark or airyness, but is also almost 3x more expensive, its sound is often compared to AMT or ribbon tweeters. A lot of hifi visitors had opportunity to listen to TW29RN a they all called it very clean, easy to listen.
