I’m going to build SL’s Phoenix, but am attracted to the all in one design of the Orion. For one thing it'll be easier in a shared room.to move around two boxes rather than four. So I’m thinking of mounting the Phoenix midrange baffle onto the Orion H frame woofer cabinets.
The W frame is wider and lower; the H frame resonance is higher (but with an XO at 120 Hz, both resonances are relatively outside the effective range of the woofers) and by the way the drivers are mounted - the W frame has the benefit of force cancellations. What do people think of the ‘hybrid’ approach? Thanks Thanks |

That's exactly what I did, so I obviously think it is a good idea.

The integrated Orion style cabinet couples the strong twin bass driver forces, directly to the mids & tweeters. By SL going this way, this did not *appear*be a problem.
Though the sound of the Orion can now be improved - Revision 0.1 http://www.linkwitzlab.com/orion-rev1.htm - by decoupling the mids from the mid range panel! So maybe something was lost in integration . . |

Beginning to think that the best all round compromise is to do a woofer ‘box’ Orion - H style, sitting underneath the midrange baffle, but just sitting off it, isolating vibrations.
This would still have the integrated look, and allow experimenting with different-better woofer locations, when "she who likes to be obeyed" is away and/ or I move to a bigger room. ![]() It does mean I'd need a pair of inverted U shaped brackets to support the midrange baffle, straddling the woofer box. Though these could be used as a base, to support midrange driver brackets a la Orion Revision 0.1. This may be a simpler path to further midrange driver isolation than the Phoenix midrange driver spline arrangement, which I hear can be fiddly to construct. ![]() I suspect that Phoenix XO would not require any change, but I still need to confirm or check this?? ![]() Thanks |

Equally of course you could do them *W frame Phoenix* style sitting just underneath the midrange baffles, with U shaped brackets to support the midrange baffles.
(Then the Phoenix XO would not require change) ![]() |

Rick,
Any kind of a hybrid.....W or H, with Orion or Phoenix style main panels is do-able. There might be some changes required to the crossover system depending upon how you implement it. Generally, a W-baffle would probably require a notch filter and an H-baffle probably wouldn't. The fore/aft position of the mid-panel relative to the bass baffle might also require some time delay. The force cancellation of the W-frame woofer is desirable if your floor construction/support is marginal. If you're on a slab or some other solid base then I don't believe the H-frame construction would be a problem. I think isolating the mid-panel from the bass is desirable in all instances. Davey. |

I have my main panel and H-frame box constructed as separate units to decouple them somewhat. The main unit normally fits over the bass, but you can see how they work here:
![]() There is a cross brace at the back of the main unit for stability. Steve

Good thinking Steve.
What do think of John K’s claims for higher output in the NaO U frame? |

I suspect he's right. I tried mine as a U-baffle and an H-baffle and I did get he impression that the U had more output.

Though was there more room interaction with the U Frame?
