How it's possible? (Soffit/Flush mount specs question)

6529 couple (or a few) thoughts: for a surround room - stereo mains in the soffits and separate surrounds (which is probably 98% of rooms i design when they want both). That would be nice, but I don't think I can justify something quite that fancy. Current plan is one set of speakers, with the fron...

How it's possible? (Soffit/Flush mount specs question)

I just wrote a long post about the subject of soffit mounting, on another thread. You might find it interesting for your question too: All about flush-mounting ("soffit mounting") your speakers - Stuart - In that post, you said: 8 ) Make the front baffle of your soffit as wide and tall as...

Stuart's Rules for Soffits / Flush mounting speakers

5853 Hi Dan. There's two schools of thought here, and both work. One is that you mount it so darn rigidly that it cannot possibly move, and therefore cannot transfer vibrations into the soffit structure. To do that, you need a lot of mass and very rigid structure, especially if the speakers are lar...

Stuart's Rules for Soffits / Flush mounting speakers

Can someone help me understand this bit: Mount the speaker inside an enclosure box that is either a very tight fit, in order to keep the speaker rigidly fixed in place, or mount it on suitable rubber pads, to completely decouple it from the the box. I understand mounting the speaker securely so it d...

Re: In-Duct Air Velocity?

My most immediate concern is the "cold" air returns from the vocal booth and control room. (I'll deal with the supply ducts later. I have a bit more wiggle room on placing and sizing those) My current plan is for the vocal booth & control room air returns to each have their own inner l...

Re: In-Duct Air Velocity?

Am I correct in understanding that duct liner is really only needed in the ducts on the inside of the inner leaf? Or is it needed in all the ducts everywhere?

(This is aside from the mufflers, which would all have duct liner)

Free WYSIWYG Residential Lighting Design Software?

At some point, I'm gonna have to make my studio look nice and I'm pretty crap with regards to being able to visualize lighting in my head. So, I'm looking for some software to help. The couple of Sketchup add-ons I've found are cost-prohibitive, but do have 2-4 week demos that I can exploit. Ditto f...

Re: In-Duct Air Velocity?

At a duct speed of 675 FPM, that would require a round duct with a diameter of 3.42". Round that up to 4" and that's too big a hole to put through a 2x10. Or you could use a rectangular duct for the portion where you need to get through the joist. For penetration of structural joists, the...

Re: In-Duct Air Velocity?

Ok, cool. Thanks. I can't run the numbers until I get home, but those guidelines actually seem a lot more generous than I was expecting; and at the risk of jynxing myself, this might one aspect of the project that turns out to be a little easier than I feared. :-p

In-Duct Air Velocity?

So, I've seen plenty of guidelines regarding air velocity at the HVAC registers (<300FPM at least. Ideally lower), but I've seen far fewer suggestions about limits for the velocity of the air within a duct. I found this post from Stuart suggesting that 675 FPM is okay. But I'm hoping to confirm that...
