Forgot the Subwoofer question. I just built a T18 tuba sub it was fun and sounds great. Bill Fitzmaurice has some great designs, I’m definitely going to build another one of his subs. If you are moderately handy, it’s worth a look. https://billfitzmaurice.info/index.html

Fwiw. I’m using an RC-62ii with RP-280Fs which are the previous model to your RP-8000Fs, so I’m going to say that will work well. I’d prefer the RC-64 but it’s really big, in size and $, plus my wife is still adjusting to the RP-280Fs, so that’s not going to happen anytime soon. I have used RB-61iis in that set up and thought they sounded good, but I had placement issues with those and switched to RP502S, still some placement issues (WAF). I’ll bet the RB-81ii would sound great with your RP8000.

Ok had a chance to play with the still unfinished T18 in the room with the LaScalas & Heresys. I had recently moved my DIY 15” sealed box subwoofer to a back corner. This alone made a significant difference in that sub. Increased volume, better and more evenly dispersed bass. I first ran the T18 solo with the LS. Super balanced sound, it compliments the LS, not overwhelming them, nor getting left behind. Just clean bass that sounds like it’s coming from the La Scalas. Perfect for music. Then tried Heresys in 5.2, I cued up the party/club scene from John Wick 2, switched on both subs, and let the magic happen. It was over the top. Both subs are staying in that system. Although, I do need to secure a couple of resonant items that are trying to ruin the good times. I’m guessing the radiator and horn subs aren’t supposed to work together? It seems like they do. I’m for sure no expert.

“ the first thing my wife said we I got home was : Wow they are ugly. The second thing: they are big!” Almost word for word what my wife said about my LaScalas, after she helped me move them in and saw them unpacked. Those look really good, I do like the “patina”. I’ve always regretted what I did do my first H1s after I got the paint off. I stained & polyeurethaned them. Which has held up well, and should last forever. However, I wish I’d just done a tung oil varnish on them. It really brought out the beauty of my La Scalas which are LS-BR. Even she doesn’t hate them, quite as much as she did that first day.

With my first H1s, one of them had a pop/cut out that turned out to be the connection at the back of the speaker terminal. I’m sure you checked this, but worth mentioning. Good luck with the issue, also with bringing back the Walnut finish. Be super careful, especially if sanding. I had to remove three coats of paint from mine. Oh, do NOT do this in your kitchen, even if your wife is out of town for the weekend. You will not get it completely finished and cleaned up before she gets back. Trust me

Nice work. Your measurements and cuts for your braces were far superior to mine. Actually all your cuts are superior to mine. I’d really like to use one, as a table. So what’s your take on T18 v Table Tuba?

You are welcome @MookieStl actually I may owe @zobsky as well. I was so pleased with the T18 I was already looking over the plans for a Table Tuba. After the review I may build another T18. Although I suppose I should finish this one first. On that front, I’ve narrowed the finish choices down to two.

Fwiw, this was 30hz test tone at 90db. Under reasonable circumstances it wouldn’t be an issue. Well then again, there is probably a reason my music room isn’t in the house. That does seem about the practical limit for this sub in that room. Two of them would likely work well with those Belle clones. I think it’s awesome that you built those. That’s some pro level cabinet making. Damned impressive.

I used the Dayton DCS 205-4. The Tang Band W8-740 is also suggested. I went with the Dayton because the specs were close, and it was quite a bit less expensive. The depth of the driver can be “no more than 5 3/8”. This is important, because there ain’t much room when attaching the driver.

Some initial testing yielded this text from my wife. Note. My music room is not even in the house. Completely detached building. She’s a tolerant woman.

I’m hoping to gain a little bit. Those RPs can go pretty low though.

I was testing it with the La Scalas it sounded pretty good and seemed able to keep up and enhanced the low end for sure. It’s not a large room, 16’X20’X7’, but probably would need two, to do it right. It certainly is a clean bass note, not boomy at all. I built a diy sub that I use with The La Scalas for music & five Heresys for gaming and occasional movies.

Thank you. I did the cuts myself. I just followed the plans and didn’t take too many liberties. There were more than a few “blade’s width” trims for sure. I did pre-cut all the pieces beforehand, due to sketchy weather.

Thank ya. I know what you mean, the B Birch never seems to look as good stained as it should. Fortunately it doesn’t have to match the La Scalas, which are LS-BR with the patina of age & tung oil varnish. I’m hoping to get it in the Family Room, where it will be used with RP280Fs, which I veneered in oak to match the rest of the furniture in the room (WAF). I might get away without it matching, as it will be hidden in a corner behind a chair. Obviously, the smart choice is veneer & stain to match the RPs.

Cabinet assembly is complete and it is functional, with no obvious air leaks. I’m still Deciding on finishing options. I’m not going black, I’d never get that nice shiny lacquer that @CECAA850 had on the one he built. Straight Tung Oil, or Danish oil over the Baltic Birch mostly works and is easy; veneer has a high WAF and my hope is to get this in the family room, so that makes the most sense, except I’d like to keep the cost down. Anyway here is a pic of its current state.

Of that, there is no doubt. It was foolish pride that kept me from asking for her help in the first place.

It took my wife less than three minutes to find it. I looked for it for two hours, and I knew what I was looking for. She was only going on my description of the box, and less than three minutes.

Final assembly stage is coming to a close. Just passed air leak tests with no apparent issues. Spent two hours looking for my gasket tape. It’s officially missing. If anyone has any idea what I’ve done with it, let me know. I’m sure some sort of weatherstripping would suffice? Then again PE, ships quickly. Or, maybe I’ll remember where the hell I put it. I’ll add some pictures, once it’s buttoned up.

They are still up, the keyhole mount is working perfectly. Absolutely no issues. As long as you properly affix the mollybolts this seems a secure mounting method.

That’s some nice work! If mine sounds good and even remotely looks that nice I’ll consider it a win. I need a break in the weather.

I got caught up in a thread started by @EpicKlipschFan which lead me down this path. I bought the plans and started gathering parts a few weeks back. The wood was the most cumbersome as I wanted to use Baltic Birch instead of MDF (Ugghhh, MDF dust and the weight). The nearest source is 3 1/2 hours away, and we just traded our only vehicle with a hitch. I had to buy some cut pieces from Rockler. I decided on the T18 due to size & possible WAF I read, & re-read the plans, bought the 8” Dayton Audio driver from PE. I’m using a Yung 300 plate amp that was insufficient for my previous sub build, but should be great for this. I started to lay out & build a couple of weeks back. My unheated garage and weeks of incessant rain have slowed progress a little bit. Any rate at the risk of finding out I’m doing everything wrong. I’ll post a couple of pics. Thanks to everyone who turned me on to this. I hope it’s as good as advertised.

I’ve got mine positioned that way for the same reason. Along the wall about midway between speakers and listening position. It sounds fine. Tbh it probably sounds better in the front pointing toward seating area. But it’s not aesthetically pleasing and it’s inconvenient.

I’ve got the Yamaha RX-A1070, which is the previous model to RX-A1080. It’s a great AVR. It has the phono input for your turntable, it works fine for me. I’m using it for Surround and two channel. It does it all from Apple TV, PS4, Bluetooth to Vinyl. I’ve never had a single issue with it. (I do run a separate amp for the LF/RF). It powers La Scalas for Stereo duty or five Heresys for surround, it should be good with the RP600s. I’m sure there are other great choices on your list too, but really like mine. Oh, btw this is in my separate “music room”. No way is my lovely wife EVER going to allow a pair of LaScalas and five Herseys in a common area. Zero WAF for sure. Good idea to start small with the RP600s and build from there. Over the last twenty years in the family room, I’ve managed to gradually go from small KSB1s to RP280Fs. However, if you are smooth enough talk her into it, Heresys are great speakers.

Just measured my RP280Fs to be sure. But 16 5/8” deep (not counting base, but with grill in place) 9 1/2” Wide (not including base)

I’ve seen some posts lately of folks finding great deals ($200 or less) on the older RC62ii. I’d consider one of those if you can find one, and if it will fit. I used mine with RB61ii fronts, and I’m currently using it with RP280Fs and it’s more than up to the task.
