Blue: = <\/strong>SB29RDC<\/p>\n

Green: = <\/strong>TW29R-B<\/p>\n

Both tweeters have the same DC resistance and they have very similar impedance curve in the cross-over region (1.5-3kHz).<\/p>\n

Blue: = <\/strong>SB29RDC<\/p>\n

Red: = <\/strong>TW29R-B<\/p>\n

Both tweeters have very similar frequency response. The TW29R-B tweeter has a more linear and extended frequency response above 15kHz. This is probably due to the slightly different shape of the face-plate.<\/p>\n

95dB @ 1m<\/strong>
\nLeft:<\/strong> = SB29RDC
\nRight:<\/strong> = TW29R-B<\/p>\n

Both these tweeters have a low distortion profile, but the TW29R-B is a couple of notches better than the SB29RDC<\/p>\n

Conclusion:<\/span><\/h3>\n

 <\/p>\n

Similarities:<\/strong><\/p>\n

    \n
  • The have identical fabric ring domes.<\/li>\n
  • They have the same voice-coil and effective cone area.<\/li>\n
  • They have the similar resonance frequency and the same DC resistance.<\/li>\n
  • They have the same frequency response up to 15kHz.<\/li>\n
  • They have the same sensitivity (92dB @ 2.83v\/1m).<\/li>\n
  • They have similar impedance in the cross-over region (1.5-3kHz).<\/li>\n
  • They have a dual balanced compression chamber.<\/li>\n<\/ul>\n

     <\/p>\n

    Differences:<\/strong><\/p>\n

      \n
    • The TW29R-B tweeter costs roughly 2 \u00bd times more than the SB29RDC tweeter.<\/li>\n
    • The TW29R-B frequency response above 15kHz are more linear and extended than the SB29RDC<\/li>\n
    • The TW29R-B has lower distortion compared to the SB29RDC tweeter.<\/li>\n
    • The TW29R-B has a two part aluminium face-plate with integrated mechanical decoupling, while the SB29RDC face-plate is made of plastic.<\/li>\n
    • The face-plate of the TW29R-B is 2mm thicker and the diameter is 0.2mm smaller than the SB29RDC.<\/li>\n
    • The TW29R-B has dual copper caps compared to single cap in the SB29RDC resulting in a lower distortion profile.<\/li>\n<\/ul>\n

      \u00a0<\/strong><\/p>\n

      The question is:<\/strong><\/p>\n

        \n
      1. Are they interchangeable with each other in the same loudspeaker design?<\/li>\n
      2. Which one has the best overall performance?<\/li>\n
      3. Which one has the best price\/performance ratio?<\/li>\n
      4. Do they sound the same and which one sounds the best?<\/li>\n<\/ol>\n

         <\/p>\n

        The answer is:<\/strong><\/p>\n

          \n
        1. Probably YES<\/strong>, but minor adjustments might be required for perfection.<\/li>\n
        2. The TW29R-B tweeter has a slightly better distortion profile than the SB29RDC, otherwise they are both top performers.<\/li>\n
        3. My personal opinion is that the SB29RDC has a better price\/performance ratio, due to a significant lower cost.<\/li>\n
        4. Sorry, I don’t know! I haven’t yet tested these tweeters in a loudspeaker design. I suspect they have similar sound characteristics.<\/li>\n<\/ol>\n

           <\/p>\n

          Both these tweeters are world-class performers. If you want the \u201ctop of the line\u201d or something with a premium looks and isn\u2019t cost-sensitive, go for the TW29R-B. If you have a limited budget, go for the SB29RDC.<\/p>\n","protected":false},"excerpt":{"rendered":"
