Had some time to get some more work done. Started gluing panels together. Used brad nails as well.






And then of course....









Thankfully since it's on the edge, I could trim it off. And then the hardwood trim will cover the hole. Starting to paint the port and port rails next.

How long are your brad nails? 1-1/4 is plenty and reduces the chance of breaking out.

I think I'm either using 1.5" or 2" brads. Probably overkill. But, I already had a box of them though.





Got some work done on painting the ports and assembling. Pictures next....

Your enclosures/end tables are looking good. I really like the grain in that plywood.. What kind of wood is that?

You might consider putting fake drawers on the front of your "end tables". It really forces the mind to think of them as furniture rather than big boxes.

You are gonna love this new set up when you finish. You've got some VERY knowledgeable guys giving you advice!

Ps: +1 on Accessories4less. I bought a refurb Denon 3313CI from them that has been flawless!

Thank you, I'm looking forward to seeing how they look when they are done, in addition to obviously hearing them. I am planning to do faux-doors on them, even with handles to complete the end-table look. The plywood is 3/4" with birch veneer.



I'm very excited to hear this setup when it's done. The B52s should be great with the HTM12s. Considering I'll be going from the internal speakers on my television to this new setup, it's going to be on a whole new level of audio for me. I'm already starting to make a mental list of the movies I want to watch and re-watch to experience them with a proper audio setup.



Thanks for the feedback on the Denon unit. I noticed that they were refurbs on the A4L site and wasn't sure if that was the best idea. But most guys seem to vouch for them.

Started working on some window braces from leftover MDF from previous cabinet builds.

They look great. I love the professional look of a bunch of braces that are all exactly the same.

Thank you - that means a lot coming from you.


And yes, I agree. It's kind of pet peeve to me when I see a lot of random width/size braces, arbitrarily placed inside a cabinet for bracing. Doesn't look as clean to me. And not that I'm a perfectionist, and in reality, once you install the driver, you'll likely never see the braces again, but still, I like to keep things symmetrical and clean.

I know I said I was set on doing a pair of HTM-12s and turning them into towers, but now I'm visiting the idea of doing a pair of Cinema-10s since the dual-woofer appeals to me more than the single, and the Cinema-10 lends itself more towards being a tower anyway.



Thoughts on Cinema-10s instead of HTM-12s?

My only thought is you’ll love them. They were my 1st diy speaker. (Non sub)
I thought they were fabulous. Very similar to the 1099, just a 2 way. And they are a nice price. But no flat pack option. But your looking like that’s not a problem!

Thanks for the feedback. The lack-of flat pack isn't an issue. I plan to build my own towers for them.



I'm just really drawn to the dual-woofer design. Granted the wave guide is smaller, but, my room is relatively small too.

Nice, is that Menards 13 ply BB? That's 82 lbs a sheet.
Yea - less dust definitely a plus.

Wow, thanks for sharing - that was great motivation. Feel free to share in my threads anytime.



I'm sold on the Cinema-10s. Now I'll have to change the thread title to Cinema-10s!

It's from my local Lowes. It's actually only 11 plys, 1/16" each, and then the birch veneer on both sides at less than 1/32" thick per side. I think the final thickness was listed at .704"



The funny thing about the dust though, I'm pretty sure plywood makes just as much actual dust as MDF, but the plywood/hardwood dust is heavier, so it settles and drops out of the air more quickly. As where the MDF is very light weight and tends to hang in the air.

Very nice! When you have a moment can you post or PM to me the cut list for those beauties? Debating whether to go floor standing or as is with those, thinking as is. In my room they should get some cabin gain to get them somewhat flat down to 40. Trying not to have to send any content to LFE from these as surrounds.

I’d need to do some digging. I think those pics are 4 years old. I’ll look.

I went with the SP-1804s. They actually have a higher sensitivity than the PA460s and model just as well. And they are cheaper.

I'm planning to build mine into towers to get the wave guide a little closer to horizontal with where I'll be listening to. Similar to what Jk did when he stacked them on his subwoofer cabinet.

I got a few things accomplished today:


- Pre-drilled the driver mounting screw holes
- Painted the baffle faces black
- Cut all of the pieces I'll use for corner trim and the legs of the cabinets













And if everything goes to plan, I'm ordering a pair of Cinema-10s tomorrow!

Just ordered 13 of those B52 drivers. Stay tuned for a few build projects! Those are truly a great deal. Lets see how many show up undamaged.

Sweet man! I’m so happy for you. I forgot who was asking, but I didn’t find my original cutlist I used. I’ll look a little better today knowing you ordered. Or are you building a custom tower?

Wow, 13?!?! Yeah, it's tough to say no to 18" pro drivers that have over 100db sensitivity for $75 each. I originally was just going to buy one and experiment with a tapped horn design for it, but after realizing that I could buy a second one and use the $10 off a $100 order from PE, I just got another. So two pro drivers for $140 shipped to my door. I look forward to seeing your build.

Thanks. And without sounding all mushy, you really did play a big part in me taking the step into the home theater world with subwoofer cabinets and DIYSG mains.



As for the Cinema-10s, I plan to build them into towers, but I'll build a block-off piece into the tower so the Cinemas still have the original airspace that DIYSG intended.

I’m just paying it forward. Lots of guys helped me along!

I can’t wait for the 1st time you fire up those cinema 10’s. In stereo, I had to keep getting up and touching the center channel drivers to make sure they weren’t on. I had never heard sound imaging like that before.

I spent some time over the weekend cutting the pieces of maple that will serve as the legs and the corner/edge trim on all four corners of the cabinets. The legs are 3" longer than the height of the cabinet, giving me the height to get the baffle off of the floor.
