I removed the bad tweeter and measured open circuit on the multimeter (the good one measured 3 ohms). I have sent both to Rob for the soft dome rebuilt and will report back later. I will also be looking for 2 original pre-used tweeters as backup.

In the eventual realm, I am working with ScanSpeak (Vifa) on a 'new' tweeter in that motor frame. My target diaphragm has the potential of greater specific stiffness than aluminum without the ringing and without the high expense of carbon. Work in progress. For now, that soft dome (I don't know how soft) was engineered to fit that motor and alleged to be plug-in compatible. Jon, see if Rob can make a frequency sweep for you on both driver types so we can compare and contrast.

Does anyone have experience matching a subwoofer to 1.5s? They get down to 42hz but I now have them in a large room so missing some bass. I removed the grill recently and saw the 6.5 inch woofer working so hard it looked like it was going to bounce out of the cabinet so I thought crossing over above 42 would make sense to take some strain off the small woofer. I've read about the Thiel subs but they are hard to find and expensive. I've spoken to REL and they recommended the T7, a pair even. I'm concerned about timing in matching with Thiel but I've read articles that say subs can easily integrate if set up correctly and there are videos for this. All thoughts and experiences are welcome and appreciated. |
@fsgattuso, While I typically suggest going low at the cross-over point to subwoofers; with the CS 1.5’s I think you’ll need to go higher to reduce strain on the woofers. Perhaps to 65-70 Hz. BTW, I strongly suggest going with at least 2 subs rather than just 1, even if the two are both smaller than the one.… …Or, just sell the 1.5’s and move on to bigger Thiels. |
