You can use any cap you have that is in the same value and similar tolerances (5% or below).

What room size do these speakers need to live a little? 

Currently I have a dedicated home theater room of about 4.5m * 4.5m * 2m (14.5 ft * 14.5 ft * 6,5 ft)

That should be fine.  That is similar to what I have them in now.

  • Finally got these painted up and built custom stands to get the g.a.f. to pull off building a home theater in the living room. These were my first ever speaker build and pleased with the outcome. Listening to them for a few weeks they sound great! Very detailed and dynamic. Way more efficient than the jbl's i was previously running. Highly recommend! Thanks toid

Those look great! I'm loving those stands. I actually really need to build some stands for mine. Believe it or not, right now I'm using some old kitchen chairs that were weren't using LOL. It is on my list of things to make though. 

Thank you for taking the time ton show pictures and letting me know your thoughts about them. They look perfect for your space.

Finally getting around to playing with shrinking this into a more compact center channel to fit in my cabinet and leave some room for the reciever and consoles.

I purchased the same drivers but two waveguides to play with

Celestion H1SC-8050 1" Horn Exponential Horn 80 x 50 1-3/8"-18 TPI

https://www.parts-express.com/celestion-h1sc-8050-1-horn-exponential-horn-80-x-50-1-3-8-18-tpi--294-2946

 

And this

Selenium HM17-25 1" Bi-Radial Horn 60x40 1-3/8"-18 TPI

https://www.parts-express.com/selenium-hm17-25-1-bi-radial-horn-60x40-1-3-8-18-tpi--264-308

 

Playing around with the layout a bit I like the idea of having the horn centered while keeping the center to center of each driver pretty close.  I plan on keeping the horn pattern vertical as Toid and JBL did, to help with imaging and prevent them muddying each other.

 

Once I land on a front layout I'll extrapolate that to the same volume that the left and right have, figure out a port or two, and make some sawdust.

 

LMK if anyone more experienced see's any flaws with the plan, or with those waveguide selections!

I really want to build these. I want to start with just a center channel for now. I was wondering if there are any plug and play crossovers that would work for this setup because I'm not completely confident in my electronics skill at this point in time. If not, is there any advice/pictures anyone would have of the completed crossover. 

 

Thanks!

There are not.  They crossovers are designed custom for this setup.  However, we can help you if you need it.

Hey Toid and everyone!

I saw the design on reddit/youtube a few weeks back and loved it. I got all the speaker components (drivers, tweeter and horn) for my father and I to make for his birthday. We are both audio nerds, but have not built a speaker yet (nothing like diving in the deep end right?!)

A few questions:

  • We saw that the holes for the drivers and horn were sunken ever so slightly. Is this just for aesthetics to have the front be flush, or will this need to be done to get them to fit?
  • I know you made the cabinets from MDF. Is there any benefit to potentially making them out of birch ply instead? (seen lots of debate on this topic and just interested to hear your thoughts too)
  • Parts express recently updates their site and all of the links now no longer work 🙁
    • We still need to do the crossover. I see you have it at 1,700 hz. Would this pre-built one for 1,600 hz be usable ( removed link )? Or one at 2,000 hz. I am guessing it needs to be 1,700 but with out inexperience and no longer knowing the exact components, assembling the crossover sounds tough
  • Would also be interested to know power recommendations. We have an 80w per channel receiver which I think should power these just fine, but still interested to hear your thoughts there too

This post lists all of the crossover components. I would recommend sourcing these via searching on PE as the crossover was designed for these specific drivers/enclosure. using an off the shelf one wouldn't be recommended. for instance the off the shelf unit won't have adjusted the volume levels for one driver or the other so it could end up with too much treble or bass (oversimplifying here).

 

The speaker recess is both functional and cosmetic, having a big fat lip around the speaker causes issues with the waves coming off the woofer, recessing it helps smooth out that issue. I use a router to cut the circles, and then use a 1/2" Rabbeting bit (making sure the original hole is the right size +1/2 to work with the mounting screws and have the woofer rim fit).  If the recess needs to be thicker than 1/2 across, I will first cut the recess at the right depth/dimensions, and then use the same center hole to cut the hole all the way through.

 

MDF is a good material for speakers as its inexpensive and uniformly dense. Baltic birch is also uniformly dense but not inexpensive.  MDF produces large amounts of awful dust, Baltic Birch doesn't. I would think both fine for this project as long as the right thickness.

@escoffee I don't see any issues with any of those arrangements.  If this is for sorely center channel use.  You could try switching the orientation of the horn as well.  You may end up liking the wider dispersion for a center. 

@pinto

You really can't just use an off the shelf crossover.  I am in the process of updating all my links.  It will probably take all day and maybe even go into tomorrow.  Eventually they will be updated.

You are the man, thanks for the input and updating all of these links. I am sure that will take time (not a huge rush for me!) but we all appreciate it.

 

@escoffee thanks for your notes as well! Looking forward to seeing your build when it is done too

Since I have been asked this a few times, the answer is yes.  Now reading, what I wrote, maybe it would be better to start with the question.  Can I turn these on the side if I prefer wider dispersion.  The answer is yes.  These can be orientated either way. When the horn is on the top, it will have a wider dispersion.  When on the side, it will have a narrower dispersion.  If you are not sure what you like, just try it both ways.  Some rooms will do better more narrow, while some will be better wider. Another great thing about this build, it offers a lot of flexibility.
