Totem Arro Clone
 
Hello guys, a friend of me wants a pair of Totem Arro Clone. I am not sure about all the details but maybe you can help me.

The things that I know are:
-Modified Peerless tweeter (aluminium faceplate ).
-Custom-made Peerless woofer
-2.4Khz Linkwitz-Reiley crossover
-They put veneer outside and...inside!
-You can check: http://www.totemacoustic.com/NewFile...l#Anchor-44867

I am thinking about using the Peerless tweeter #812687 and the Peerless woofer #850488. I am not sure about the crossover parts. For sure they use bypass oil capacitor.

Do you think the drivers are correct? Are they superior or inferior of the one used in the real thing?

Any comments are welcome.

I always liked the cosmetics and idea of the Arro. I have given some thot to doing something in the same vien, but adding another midbass (probably hidden on the back). The pair of Arros i heard weren't all that special on limited listening.

The Peerless mid-bass they use is as you say custom, so the DIY version might be similar -- it might not. And as soon as you change the drivers, the XO follows.

I totally agree. After a quick look to the frequency response of the two drivers, it seems that I can begin with the same 2.4Khz value and fine tune with some listening.

as long as you are going this route why not start from the begining.

in teh 14cm range I like the SS 8530 - 9900 combo. Yes the 9900 is about 6db more sens. than a 8530. factor in difraction and you have a bigger difference. however I think Daves suggestion of a woofer in the back might make sense besides it might help compensate some difraction loss too giving you 3-6db more sensitivity.

the Peerless CSX 14cm woofer would be my second choice.

Any idea of what kind of damping material they have put inside (like white paint)?

Also, Totem may use lock-miter joint. This is a picture of one of their box:

Might be one of those borosilicate stiffening compounds. Anything you can apply to the box material that creates a layer of material with an indistinct edge that stiffens the outer layer can have a significant effect of the material stiffness. Epoxy, fiberglass resin, varathane.

I am wondering if I can find a similar stuff at my local hardware store.

I will also try to search for a router bit similar to the lock-miter design.
