Alpair 10 and 5 Combination

[_henry_]

is this the best combination?

Deep bass, and full extension highs?

i saw this in a japanese website

nice pictures of solid wood alpairs also

some super tweeter with solid wood enclosure

try to decipher using google translate, no luck , cant even understand half of it

actually this is what's on my mind

I'd try to get the drivers closer together.

i agree, there's a tendency for diy to make the cabinets from solid wood

Do u think this is the best combination, dave?


even the curve ones, the stacked planks and cut to curve and routed curve inside , that's alots of material waste.

another one

[ that's alots of material waste.

And i don't think it uses the material in its best direction.

Although i know VANDERSTEEN REFERENCE uses this method for their midrange/woofer and tweeter

I guess better way to do it, is bend the wood or plywood and make a frame for the front and rear baffle.

what do u think dave?

 

[_henry_]

thats what they are after

any chance to make this M-Onken?

dave??

That 'two way' alpair with one of those 'super tweeters' on top should make a great sounding system IMHO.

Wonder how something like that would compare to 70 and 80 bookshelf style AR, ADS, Cizek, etc...

I want a set!

Given the Alpair 5 operates well into the lower midrange, you probably won't need to get the drivers much closer than shown in the photo. My Jordan 2"/bass combination crossed at 500Hz and was about that distance apart. Sounded fine. The Alpairs will probably crossover lower. Besides, they need to be in their own separate enclosure (I assume, if like the Jordans) so you have to leave room for that.

I'd question the need for a supertweeter with them. The Jordan JXR6, which is similar, operates up to 30kHz.

 

[_henry_]

another Super Tweeter? the alpair 5 can go to 30khz

 

[_henry_]

you're absolutely right colin.

so how do you did for the jordans?

its jx125 and jxr6?

can u share the pic and experience please?

cheers

You we'll know one of the things i will try....we may have one that is a surprise -- at least for the CHR 70.

great combo... I understood from some forum and magazines that at least a few German designers are also working on a design with the Alpair5 and Alpair10bass

I'd try to get the drivers closer together.

would look a lot poorer, this appears to be golden ratio... and like Colin said, when crossed low enough probably not needed.

 

[_henry_]

if we put 2 Transmission Line in 1 Cabinet, similar like what B&W did with the Nautilus, let say the Alpair 5 on the top and Alpair 10 slightly lower that goes to the bottom maybe exit on the back

do u think this would be a good setup?

 

[Henkjan]

you mean a well damped TL for the Alpair5 to get a clean midrange (backwave gets caught in the TL)? nice idea... some creative woodworking required, but worth a try I's say

 

[planet10]

The sketch below is for our as-built Tysen with FF85 and sealed SDX7. The 1st concept had Jordan J6T/Alpair 5 ... i'm using the sketch to illustrate a possible approah to the double TL.

The aperiodic TL on the top is a straight-forward high ratio aperiodic TL -- if needed it could be rotated so that the botton was parallel to the ground and the top was sloped down towards the back.

What is a holey brace in the sealed box could easily be a TL partition. With Alpair 10, putting the driver on the front is probably a good idea. Further, to take advantage of optimum driver offset, i'd add an additional partition so that the back part of the line can be extended to have the terminus on the front/bottom. This should rotate the line sufficiently that the A10 will be near the bottom of the A5 TL.

No one went for this (AP5+10) ?
Would have thought a 1st order Xovr would be really nice ??

This project hasn't reached the top of the queue (+ i still need to get a A6 woofer -- no pint in using a plain A10)
