So, as you may have guessed I am pretty fussy about speakers. The B&W 602 S2 are very nice but still not what I am looking for as a match for my DIY F6 (Thanks Nelson!). So I started to wonder why the Infinity RS-2001s I was given for free sounded so bad. Went back and took a closer look and discovered two things:
1.) The woofer had been replaced with an after market version that was entirely a wrong match for the xover and box, and
2.) Both tweeters were blown.
So I had a choice, dump them or bring them back to spec. I chose the latter even though I would be putting more into them than they are worth. I am retired with time on my hands and needed a project. So I decided if I was going to fix them I would do it right. I bought a pair of original re-foamed woofers off of that auction site and then skipped right over dome tweeter replacements and grabbed a pair of Infinity EMIT tweeters.
The trick with EMIT tweeters is that the xover expects to see 6 ohms for the tweeter and the EMITs are 3.4 ohms. So at the risk of knocking down the tweeter output a bit I put a two ohm resistor in series with the EMIT to get the impedance closer to what the xover wants to see. I also doubled the amount of damping inside the enclosure as it was a bit boomy sounding. The result is awesome! I am also going to add some internal bracing to further settle the enclosure down.
