RTI Tweeters

Posts: 124
As a fun project, I am replacing blown tweeters (RD0690-1) in my spare RTI4's (in addition to replacing a blown crossover resistor and blown driver). Based on specs and faceplate fit, I've narrowed it down to 3 choices;
-Peerless OC25SC65-04
-Eminence SD28
-Dayton ND25FN-4
All will require minimum faceplate alteration (slight enlargement of dome opening). All have similar sensitivity, Ohmage and power handling. The Eminence is about 30% more expensive. The Dayton looks to have better heat control but has a listed low end of only 2500Hz, compared to 1300Hz and 1500Hz for the other two (although Dayton's graph seems to show them handling 1400Hz). They all top out at 20Khz. The RTI4's crossover at 1900Hz.
Does anybody have experience with either of those 3 tweeters, or perhaps additional options not listed? Value wise, I can't justify repairing these speakers, so I'm doing it just for kicks. All in, it will cost around $100 Cdn. Any thoughts?

True. That's why I'm going the aftermarket route, which may or may not be an upgrade, although I read Polk was using Vifa tweeters at some point, which I believe has some association with Peerless. The RTI's were rated up to 26,000Hz, and neither of these replacements is rated at more than 20Khz, but I don't see that as a factor. Polk keeps their driver specs pretty close to their vests, so the only knowns are the Ohm rating and physical size.Polk RTIA3 Fronts

It's a crap shoot only if my goal is to maintain the authenticity of my RTI's. It's a crap shoot buying Chinese aftermarket components. Dayton and Eminence have a good reputation, and Peerless is not an unknown source either. While replacing with aftermarket components will definitely change the RTI's performance, it might be for the better. As I stated at the beginning, this is just a hobby rebuild of speakers I don't even need. As an added bonus, I'm learning a lot about speaker components as I go.

Actually I did get the RTI4 woofer he had, but when I ordered it, he only had one of the two tweeters left. So rather than chasing down another one, I decided that, for the same price, I would just order new. But as you had previously mentioned, his packaging is amazingly secure.

Well I went with the Dayton's (ND25FN-4) and although I thought I would need to slightly modify the faceplate opening for dome clearance, the faceplates actually have a stepped opening which allows for proper clearance of the dome's outer rolled ring. The outer diameter of the Dayton is exactly the same as the Polk original (41mm), and they insert snuggly without having to be forced in. The Dayton, like the original, has a multi-point star heat sink on the magnet which is exactly the same (diameter, number of points, thickness) as the Polk. The thickness of the locking nubs are the exact same, allowing for push and turn mounting with the faceplate's clasps. It's basically an exact clone of the Polk, although Dayton makes no mention of Polk applications in their spec sheets. The rated wattage and frequency range should pair nicely with the Polk crossover, and the 90 db sensitivity should also match well with the Polk woofer. I'm still in the process of repairing the crossover (needs 2.5 ohm 5 watt radial resistor, or equivalent), and then I'll report back with a sound test. It's fairly easy to remove the Polk tweeter from it's faceplate by cutting the thin (RTV like) glue, and twisting it to release the nubs from the clasps.Polk RTIA3 Fronts

Correction: The faceplate opening does require very modest enlarging of just less than 1/8" in total.Polk RTIA3 Fronts

Not sure if the RTI and RTIA's have identical faceplates and tweeter cup size but I will document and take some pics. I will say it is almost impossible to remove the old tweeters without damaging them, but if they're toast already, the process is simply a matter of tracing around the outside edge of the old tweeter with an xacto knife, being careful to stop at each of the 4 plastic clasps holding the 4 tweeter nubs. If your old tweeter has a star-shaped cooling heat sink on its back, you can then use it to rotate the tweeter about 1/8 of a turn to disengage the nubs from under the clasps. I used channel lock pliers to twist mine. The tweeters aren't really "glued in". The sealant is really just to prevent the tweeter from rotating. The plastic clasps are what holds the tweeter in place. The sealant is much like a thin layer of "RTV" like material, and cuts fairly easily. I intend to use hot glue when reinstalling the Daytons. It's not like a tweeter jumps around much while running.Polk RTIA3 Fronts

*RTi & RTi A series speakers use the same tweeter
ok so here was the basic procedure. I cut the old sealant around the perimeter of the back of the old tweeter, and twisted it out from the perimeter clasps. Because the Dayton had a thicker flange than the Polk, you need to cut off the plastic retaining clasps as well. The Polk faceplate mounting hole has a slight bevel around its opening. As the Daytons require a 34MM dome opening, and the Polk faceplate has a 31MM opening, you need to enlarge the faceplate hole by about 3MM, or about the size of the bevel on the original faceplate opening. I used the edge of a utility knife and shaved it. The tweeter cup size of the Dayton is 41MM so its a perfect fit O.D. wise. For added measure, I re-bevelled the faceplate dome opening to ensure that the rolled surround on the tweeter had extra clearance. I then installed the tweeter on the faceplate, and used hot glue to make it air tight. The Dayton tweeter paired well with the OE woofer, and to my untrained ears, reproduces midranges slightly better.

Actually, at first I thought the black tweeter would look funny as a replacement, But it actually blends well and is balanced by the look of the front port. I haven't really cranked it, but so far, I'm pleased. It may be a db or two more sensitive than the original (or it could be the Mills resistor upgrade) but it has a more crisp sound, while still being warm.Polk RTIA3 Fronts

This is probably one of the best aftermarket mods I've seen purely because of how perfectly it fits with so little modification to the enclosure.
Looks awesome. -
The trickiest part was finding a reputable tweeter that would fit. I was originally going to go with the Eminence SD 28 but Solen was out of stock, and recommended the Dayton instead (which was already on my list of options). The Dayton has the same heat sink as Polk on its back, although I believe they can be transferred over to the Eminence as it appears they have a threaded hole on their rears for that very purpose. It was a fun little project though in the grand scheme, not very cost-effective. They do sound as good or better than new.Polk RTIA3 Fronts
