Default Chassis for Sachiko

Hello,

I want to build an Sachiko. But which would be the best chassis for this cabinet (I don't like the fostex fe206e because of it's frame-style ).

So have searched for this alternatives:
Audio Nirvana Super 8 (maybe the cast frame)
Fostex FE206ES-R
Hemp FR810HQ
Lyeco LY802F
Supravox HP215RFT64

So, are these alternatives equal for the Sachiko or are there some "no goes"?

Thanks
Armin

You are obviopusly a man of taste and decency.

OK, the Lyeco & Supravox are out -Q is too high for this cabinet. The Hemp is borderline, though again Q is a little high, and it wouldn't be my first choice.

The FE206ES-R works very well: there's already a pair of Sachiko's using them to good effect. And the Audio Nirvana Super8 cast-frame should work fine too. For myself, I never found the FE206E as unattractive as all that though...

Hope this helps
Scott

... it helps (but I don't like the result). So I must build a blind/faceplate for the chassis.

Is only the Qts is relevant for the cabinet (<0,4)?

Thanks
Armin

I thought you liked the ANS8 cast frame & 206ES-R? As I say, those will work fine. The FE208ESigma (you'd need to add a tweeter to that -the FT17 is a nice unit, and not particularly expensive) should do a decent job too.

Q is not the only factor, but it's one of the most significant ones. Vas and Re are also important. As a rule, the higher the Vas, the larger the cabinet you'll need. Re also affects the shape of the response.

Best

DOH!

Today I was in a wood store.... i asked for finnish birch plywood and they want 450 euros....

Definitely to much for my money. Sad, but true.

Anybody can say me wich kind of wood could I use for a good sonic performance at a more human cost?

(ps: I find mdf not so actrattive.... veneered, more cheap alternatives?)

Could I alternate birch with other wood in the same cabinet?

Thank anybody for answers

You could try a mixture of birch ply & ordinary, cheap chipboard (particleboard), with the ply for the side panels, and, if there's sufficient, the rear panel, and the chipboard for the rest. That should cut cost somewhat & work pretty well.

That's could be an idea.... but the side/rear panels are big and I could save only a few money.

What's the result using mdf for side-rear panels (obviously less fashionable, but I must wait the day that I become rich! )
and russian birch ply for baffle / horn panels?

BUT

I've read that mdf can sound harder and harsher.... (but particleboard is to horrible outside the cabinet!!)
Isn't true?

Ps:Thanks Scott
