Hi,
I think I'll start my new project around December. I've been on the planning stages for this one since February or March (I actually got some of the drivers back then), but only now I've begun to set my goals.
I've decided on the following.
1) WMTMW, at least 100 liters.
2) W -> RS225's
3) T -> RS28's
As you can see, "M" is still under consideration.
The thing is - I've madly fallen in love with my Seas CA21 / Neo8 / Neo3 speaker. This is the first time I've really liked a design of mine... and I think the reason for it is the midrange. The crossover frequencies I used were 800 Hz / 7 KHz, 4th order acoustical. The midrange is magical - unlike the speakers I own. For the lack of a better word, I'd say it's cohesive and smooth. Maybe not having a crossover near the 1KHz - 4KHz region is worthwhile; at least this is what I understand I've learned via trial and error.
So, I'd like to take what I learned with this speaker, and design something bigger, more dynamic, but with similar midrange characteristics.
So... the original "M" was supposed to be the RS125 (I already have 4 of them). But I don't see a lot of potential with this design - crossover points would have to be (in order to keep a 3 octave spread) 300 Hz / 2,400 Hz, 4th order. And I'd place the crossover right in the middle of the region I'm trying to avoid.
Second option: the RS52 (I have a pair of them). I could get away (I believe) with a 700 Hz / 7 KHz (or more) crossover - basically using the RS28 as a supertweeter. This sounds tempting enough, and dual RS52's would drop distortion figures quite a bit.
But there may be a better way...
Third option: the Tang Band W4-1337S. I've used them on an MTM speaker, and I can't say enough good things about them. I love everything about them (except, of course, their price ). I'd need to buy 4 of them. But I'd use something like a 300~400 Hz / 6~7 KHz 4th order acoustic filters - basically, the best of both worlds. Knowing already how good these drivers sound, and thinking about using the woofers and tweeters just to "fill in" the rest of the spectrum makes me believe this could be a very "coherent" design.
There's only one problem I foresee - off-axis response may not be good enough for me to use such a high crossover point. But even using a 4KHz crossover point would be good enough for my goals, I think. Maybe 5KHz...
Also, this would add at least $250 to the project....
I believe my best option would be to use the W4's, followed by the RS52s, and the RS125's. Price-wise, the RS52s may be the best idea.
But hey - if going for the W4's would give me the best sound, I'll start saving now....
What do you think?
