Spica's TC 50 vs. Sound Dynamic RT 3's

I owned a pair of TC50's from 1990 through 1993. I bought them because I moved into a small apartment.

I enjoyed them and they served me well. They are not well extended in either direction but what is there is fine. They have a good upper bass, which can give you a feeling of what is below. I think it is generous to say you can get 60hz solidly from them but I never measured them

The midrange and sound stage is what made them enjoyable. Also, although they go south after 16,000 they have an Audax soft dome which is smooth. They won't play at head banging levels but can handle 90hz or so in the right room. They can tend to compress if driven too hard.

Finally, both drivers are hard wired with no protection. So, if you are not feeding them good clean power you can distroy the drivers. However, they were out sourced and easy to replace.

One more thing is that they do need power. They are not they most sensitive speaker. I would say at least 100 watts with current.

I am going to respectfully disagree with a couple of posters on the power dept.. They are not the most efficient speakers in the world, but also don't get the idea that they will play loud if they have plenty of juice. If its in your office, I doubt that it is much of a concern.Just treat them like you would your Quads and it will be fine. I thought they sounding great on Audio Research/Dynaco Stereo 70.

Had the 50's and blew them. Amp was turned up all the way before warming up. Then it powered up.(it wasn't me!)
Replaced them with 60's which have just a little more at the extremes. Ported and a little more punch. Just a little less Spica sounding than the 50's but definitely still Spica's.
Just like to point out these speakers are amazing in my small bedroom, about 10'x 12'. Moved them into my larger den and the sound just collapsed, not just the bass.

I use Spica TC-60's in my main system, but I also have Axiom M3Ti's in a secondary system. If you are considering the RTS-3's, then I would recommend you look at the Axioms, as they have a very refined sound for the money.

While I've not heard either, I have read what Stereophile said about the RTS-3. And, AudioAdvisor has them on sale for 199. So, I'd say get a pair, listen and if you don't like send them back and your only our some shipping costs.
