Its time for bigger and better things.

Receiver wise, I'm a huge fan of Rotel and Yamaha.

The dual Mid & Tweeter Setup would be good if your sub doesn't do so good in upper registers, other wise the Mid & Tweeter would be fine. Anyway, Ascendent setup is a good way to go. For the whole system, L&R center and surround....

Sounds good.

Ascendant is the way to go.

Would it be better if I used the dual mid and tweeter for the L&R and then the single mid and tweeter for everything else?

Dual mid and tweet on left and right.

30Hz ~ 300Hz to 400Hz Low-Mid

300Hz to 400Hz ~ 1.5KHz to 2.5 Khz High-Mid

Tweet everything else.

Center Channel

Since it's voice usually I would not cross over anywhere in the vocal range ie 700 to 3.5K which makes a hard choice, ppl will disagree with me on this. You will want the mid to go high or the tweeter to go low. Those Vifa XT25 Tweeters will do it, so i would XOVER low. If I remember right those tweets are clean down to 400 I think, but by no mean would I run them THAT low.... Were still experimenting before we build.

Surrounds.

30Hz~1.6 to 2K Mid

Tweeter Rest of highs...

The Jon Marsh 'Modula' designs would be on my list of budget high end loudspeakers.

[see anything with the words modula on this forum or Dayton RS]

http://www.htguide.com/forum/forumdisplay.php4?f=6

Because;

1. He's a clever analog designer that has optimized his passive crossover

{CE filter that mimicks 8th order slopes} for the new Dayton Reference drivers

to extract the best SQ possible from 'metal drivers' which are notorious for

sounding edgy without a proper crossover design.

2. The Dayton reference tweeter cost about $50 each and competes with

tweeters costing double or triple from name brand manufacturers.

3. All the engineering work done including the use of PE cabinets, IIRC.

IIRC, the original Modula design didn't use Dayton, but he converted the design

to use Dayton drivers.

This might be cheaper because;

Same type of design but only a 4th order crossover which would be considered the

minimum required to make the metal drivers sound good. But the Modula's 8th order

should rule more. Simpler crossover design = less cost.

Whats your opinion on crossing over in that vocal range on a setup that is going to be just a 2.1 home audio (some movie) setup? Is it nearly as critical since it isn't a center channel, and from my understanding of surround sound, the center carries alot of the load? I am just wondering if I'm should look into rethinking my next design a little to accomidate the cross over under 700hz.

My current plans are tripple AA 6.5's with one of the K1 tweets (http://www.madisound.com/cgi-bin/index.cgi?cart_id=4946185.10725&pid=1824) off of madisound at 2khz.

Ideas?

Thanks

I don't see a real reason why you'd change design methodology

because it's a center channel. In fact, there are some great

designs where the center channel is more complex in design than the

mains. Even these designs with 4 drivers seem to 'busy' for my taste

but they are engineered correctly.

What do you guys think about any of these kits on madisound?

Reason why I do it different in the center channel is it handles most of the vocals/spoken word, especially in movies. And by crossing over in the vocal range you get the same voice coming from 2 places and from 2 different types of transducers which can sound a little funny.

Plus, if they don't cross over just right then you can end up with a drop in the frequency response at an important vocal point.

However with L&R mains you get a lot of other concerns. I would rather run a 3 way system that is set up so everything below 300 Hz is ran on one part of the load, 300 Hz to 3 or 4 kHz are ran on the other and then a tweeter caries the rest of the load. And honestly it really really depends on your speakers, more than anything, because for the Ascendant Audio stuff, the mid-range speaker isn’t going to sound very good up at 4 kHz because it’s not designed for that. So, you have to weigh out what you want. Otherwise, 1.6 kHz or 2 kHz is usually a safe place to crossover with out putting any undue stress on your tweeter or mid-range.

Would the ascendant set be better than any of those other on madisound?

And you want to stick with the same speaker for all channels correct?

The real answer is. What sounds best to you. Since you can't audition the speakers

mentioned, you are essentially gambling that you will be satsified. If you can't

audition, you are trusting the design by analyzing it closer to make sure it's

engineered well, and/or trusting user testimonials.

And you want to stick with the same speaker for all channels correct?

It's nice to have all speakers the same, but there is nothing written in stone

that you must do it.

So in essence you are saying to get the 3 ways instead of 2 ways?

Yes the L&R would be a 3-way. Other wise if you double the mids you would have to fine 2 mids with 2x the DCR as the tweeter. Also, be aware that the overall resistance of the AA stuff is going to be around 4 ohms and most receivers can do 4 ohms but are set up for a min of 6 ohms.

Correction on the Center Channel. After playing with the stuff last night the tweeter wont extend down low enough for what I said. So for a center channel I would run the mids up to around, but a little lower than 3k, because they will extend that high and sound fine.

 

[btnhfan 5,000+ posts]

For the satellite speakers those would be fine with 2 ways right?

I think Ive decided on these MTM's, unless anyone has any objections.

And then go with aa mt's maybe.
