just say I risk it and get three of these kits sort of but without the crossover, build my own box veneer it to my taste and go with the 2 way active crossover and probably some pro audio amps. or a 7 channel amp.

would i still need xover's?

I am also liking these allot

http://www.selahaudio.com/id14.html

would it be possible to use those as l/r/c?

Cant I use it in a 2 way design and use it for left/right/center? and get a 7 channel amp? or 3 pro audio amp?
Says online it has 3 inputs and 6 outputs.

Remember ill be powering the rears with my receiver. (dont care how those sounds lol)

I checked the online manual. Page 10.

They show {figure 4.2} that you can configure it for LH LH LH, triple biamping.

Figure 6.3 shows 3 x 2 way configuration.

I would have to verify with my DCX to make sure it does high pass and

low pass on the midranges.

If this works, you are good to go .. LCR

shine the rear surround...

re: Selah, RAW, GR-Research, etc.

Their forums are located here;

http://www.audiocircle.com/circles/index.php?PHPSESSID=q6i6h7onvarok0c89tinuek777&action=circles

Each manufacturer has their own forum section. You can go there to

do some research on those kits and ask questions.

If you used a DCX instead of the passive crossover design made for

a particular kit, you should be able to extract high performance from

the kit.. Because you can try different crossover types, Butterworth, Bessel,

Linkwitz-Riley, plus you have 6dB/octave up to 48dB/octave slopes. My favorites

are 3rd order {18dB/octave} Butterworth, and 4th and 8th order Linkwitz.

The crossover frequencies are swept in small increments of a few hundred hertz,

there is PEQ's and delays to mess with. You can do shelving filters too if you want, they look like this.

In many ways you can probably extract better performance from a kit,

minus their passive crossover, but add the DCX. The DCX allows so much

tweaking that you can easily find the sweet sound.

re: http://www.selahaudio.com/id14.html

LCR ?

This is a 3 way, so one DCX isn't enough to do LCR. You can probably

convert this center channel design to L and R speakers. Rearrange the drivers

so it looks like this one;

But you will have two midwoofers on the bottom. You'd get more bass.

Partexpress has cabinets for loudspeakers.

Exotic stuff

Mini ribbon for MTM - to keep midrange center to center spacing low.

Does Linkwitz have anything that catches the eye?

http://www.linkwitzlab.com/

Lots of people like the Orion, it's fully active with custom active crossovers ->

"The completed speakers cost around $2200, without power amplifiers."

Raw kit looks like so;

http://www.linkwitzlab.com/images/photos/Orion_Raw_Kit.jpg

Looks like an easy project.

For center channel, find a kit with the same tweeter and smaller Seas midrange.

Pluto would be neat for surrounds.

I am still liking that one the most so far.

for surrounds I dont care ill keep running what I am running now.

any other recommendations? dang thylantar your sure are very knowledgeable when it comes to diy.

I am gonna talk to my box builder soon, see if he can come up with some sleek box designs for that kit. I can build the boxes but I want them to come out flawless without a single imperfection so I rather have my friend build them //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Go to the Selah forum {audio circle} and see if you can get some user

testimonials on that speaker. Dig up some dirt before you tackle the project.

This is a complicated design. Ribbon + dome midrange + seas midwoofers.

You can simplify this. You can use a bigger ribbon, maybe the $125 or $300

Fountek, implement an active steep crossover, slope LR4 or LR8, and use

those Seas mids, but I'd still chose a pair of PHL1340 midwoofers over Seas.

The Fountek NeoPro5i is nice. Expensive, high sensitivity of 102dB. // nice //

The $125 Fountek NeoCE2.0 is good too.

http://www.madisound.com/catalog/product_info.php?products_id=1556

This is branwell's system using PHL1340 midwoofers. I don't remember the

tweeter, maybe Morel? Dual Peerless XLS subs, IIRC.

http://home.pacbell.net/lordpk/phl/6.JPG

He like the MTM with PHL over the same design using Seas midwoofers //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Even Pass Labs likes PHL mids as they are used in the Rushmore fully active

loudspeaker, check it out. IIRC, Raven ribbon, PHL mids, and rumored to

be custom PHL midbass. It's a higher sensitivity design. IMO, better dynamics

are had.

Here's another system using the ~$100 Fountek ribbon, Audax PR170M0 {identical sound to PHL1120} and dual Lambda TD15X woofers.

http://home.pacbell.net/lordpk/phl/1.JPG

This is a 3 way system though. It might look ordinary but those combinations can

yield very high SQ. I would have just centered the drivers or make a dual cabinet

maybe like so using those driver combinations.

You have to figure out if you like ribbon tweeter sound or dome tweeter sound.

If you like the ribbon tweeter sound, the Fountek brand is very nice for the money. Rick @ Selah uses it alot in his line arrays and the composite ribbon design is more robust than the designs using an aluminum element, ie Raven

or AC ribbons. There really is no need to look at those expensive ribbons.

On the other hand the Raal is very interesting, those are more unique.

For wider dispersion, the small ribbon is needed but they are crossover frequency

limited. That's why the Selah center channel you like needs a dome midrange,

because that small ribbon can't be crossed over lower and the Seas midwoofers

are just poor performers in the higher crossover frequency range. In other words,

Seas Excel is high end drivers, but they are not forgiving and don't offer as much

design flexibility as the PHL.

If you use the larger ribbons, you can lower the crossover frequency but a larger

ribbon has weaker vertical dispersion so you need to aim the tweeter towards

the listener to get the sweet spot. Catch 22.

The LCY ribbons look interesting as they have wide dispersion like a dome,

claims of 2.5khz crossover can be used, easily integrated with dual PHL mids.
