New member Username: Tsmith48Post Number: 1 Registered: Feb-08 | I have an old set of Sansui SP-200 speakers I bought on craigslist for $30. One of the woofers rattles at moderate volume. I'm thinking I could replace the woofers with a pair of 12" car woofers I have access to for next to nothing. I'm not looking for some kind of collector speakers or audiophile level sound from them....just stop the rattling. In the old speakers the tweeters are 16 ohm, the woofer and midranges are 8 ohm. The car woofers are 3.6 ohms. The overall speaker is rated as 8 ohms. http://www.classicsansui.net/images/Literature/Speakers/SP200%202.jpg In ancient history, when I had a set of 4 ohm small Advents, the store had me install a 2 ohm resistor in line with the speakers to better match the 8 ohm amplifier. Is it possible to similarly replace the old 8 ohm woofer with a 3.6 ohm woofer with a 2 ohm resistor in series with it inside the box and have the resulting combination similar to the original? I'm hoping to get the project done this week. Thanks for any help you can give me. |

Even if you're not looking for quality sound, you'd be better off buying drivers that come closer to matching the original design. Woofers need to mate well with the enclosure and should be of similar impedance and sensitivity. Matching basic parameters of the driver will result in better sound quality than just sticking free drivers into the existing box. Call Parts Express for some help. http://www.partsexpress.com/index.cfm . |

I have a set of Sansui SP-7500 speakers and replaced the tweeters (only one out, but replaced both with same unit) with tweeters from Parts Express that came so close to matching the old speakers, I could even reuse the screw mounting holes. |
