Hey, dear DIY Speaker enthusiasts--

I used to own a pair of Revel Ultima Studio speakers. At one point, I heard persistent scratchiness on vocals, and Revel sent me a set of spare tweeters (two front, two rear). The problem turned out to be something else. I suppose I could return them to Revel, but are they of any value to anyone else?

the problem with tweeters built or designed for a specific speaker is that unless one completely revamps the crossover then they're pretty much useless except for that one speaker design. If some intrepid speaker designer has a desire to use the TS specs of that particular driver and built a speaker around it then maybe, but right now I'd say that they're best used as spares in case you blow any tweeters for your Ultimas

Original Studio or Studio2?

Michael, understood. Though many of the DIYers I know are using things like miniDSP, which perhaps can take care of such things?

Original Studio. They were sold about 5 years ago when I moved to a new room.

sorry for the late reply Mike... I got distracted with film reviews this week...

a mini-dsp will do very little when you're trying to implement a tweeter into a speaker design. It's takes a lot of guess/test/revise and technical fun to implement a speaker with a designated woofer and then of course designing what cabinet it will go in. You basically have to build your own crossover from scratch to make them work together, and not every tweeter will like every woofer. It's a balancing game of trying to find the woofer that meshes well with your tweeter, and then playing around with capacitors and resistors on a crossover till you get the sound you like. It's why companies spend MILLIONS on R&D for their speakers as you can't just slap a tweeter and a woofer in a box then play with some EQ settings and call it a day.
