[THX-504-L Enclosure Volume]

Curious about what the OP went with.?

Did you attempt an enclosure or did you just cut rectangles out of your sheetrock and tighten the screws?

Im looking at the same project with the same speakers.

(3) Klipsch THX 504l

I'm yet to install them but have designed sealed boxes out of 3/4" MDF with a capacity of 1.29 cu ft.  I don't have drywall, I'm building my own framed drywall against a solid wall at the end of my room so the boxes will fit between my drywall and the solid wall.

 

So I have no idea yet how well this setup will sound I'm afraid.

As for your questions, they appear to have been answered.

Correct?

 

I guess, infinite baffle.  Thanks all.

I'm just after the best way to install them as there is no guidance on that from Klipsch that I can find.

 

By best way I mean open baffle or sealed box really.  I know how to physically install them with either option.

 

@001 says sealed box, @Scrappydue says open baffle and Klipsch themselves say ask a professional installer. 😭

Are you just wanting to enclose them to try and contain some sound?  

 

I'm just after the best way to install them as there is no guidance on that from Klipsch that I can find.  They just suggested "reaching out to a professional installer" but I'm not in that market.

That's right. I forget the select line doesn't but the ultra line does. Is there any way to utilize the 8000-L instead? Could the 504's be returned?

 

I bought them (lightly) used so no, and I'm happy enough to DIY some sealed  boxes.  I just needed some advice on optimal volume.

if the speakers already have enclosures, why are you wanting to swap them? 

 

They don't have enclosures. See my original post:

I have three THX-504-L speakers that I plan to use as LCR in a home theatre setup.  I'll be building a media wall/baffle wall at the end of my room into which the speakers will be mounted.  I am assuming that a sealed enclosure behind each speaker will give me the best results but I'm unclear what volume the enclosure should be.

 the internal volume enclosure must remain within klipsch specs , I would not go lower to 1 or 1.2 cubic feet as the  RP -504-C II  still requires a port  at the rear of the cabinet.

Okay, so aim for around 1.29 cubic feet.  Does that make sense?  My boxes will be sealed.

as an example   , here are dimensions of a klipsch external cabinet with four 5.25 inch woofers and a HF driver and identical  specs ,

this should give you an idea  for  the THX-504-L  enclosure's  ideal depth and height   , you can figure out the exact width  by adding 3/4 inch MDF  all around  .

  

 

 HEIGHT INCHES (MM) 6.87" (17.4 cm)
WIDTH INCHES (MM) 32.06" (81.4 cm)
DEPTH INCHES (MM) 15.08" (38.3 cm)

Thanks.  So that's the RP-504C II I guess.

 

Assuming a wall thickness of 3/4 inch (18mm) that would make the internal volume around 1.29 cubic feet.  Does that sound reasonable?

 

I've seen posts elsewhere suggesting 1.0-1.2 cubic feet.

I did email Klipsch support but they just said:

We provide specifications for speakers, but anything having to do with installing architectural speakers, we would suggest reaching out to a professional installer.

 

I can't afford to use a professional installer so can anyone here provide any information please?  I'm just after the optimal volume for the enclosure.

 

Thanks in advance.
