No worries, bro. In fact, here are some more pictures to inspire you!

Just finished installing the port tube and the side panel with the port outlet.

Nice job there btp! Would you mind including a shot of how you did your terminal port? I see you have a square block there on the interior side.

You can see the recessed "hole" for the terminals in this picture. The hole is 2.25" in diameter. I used a square block on the inside basically because I was too lazy to cut another circle with the router. I'm using the Dayton BPA-38G HD Binding Posts from Parts Express (part # 091-1245). When the posts are screwed all the way down, they are actually flush with the rear panel of the box which I was very pleased with. Initially I wasn't sure if the 3/4" recess would be enough to make them flush.

Made a little progress this weekend. Not sure I'm doing all that much better of a job on subwoofer #2, but no major problems have cropped up so I guess it's all good.

Bondo!





Lots and lots of hand sanding, then shot it with some paint just to make it look uniform (and make myself feel better).





All four sides on... front, back, left, right.



The last of the braces... damn port tube! Totally in the way.



Other end was easier.



Looking like a bona fide "box" now.

My god..

I had to sell my RLP18 before I had a chance to listen to it.
Just too freakin' big.. Dunno what I was thinking when I ordered it.

If yours came with any vinyl decals, I made 'em.
Mike @ SoundSplinter is a /great/ guy to do business with.

So here's a Chihuahua in my RLP18 for good luck with your build.

Big chihuahua.

12" Beyond Audio X-one, 15" Orion HCCA, 18" RL-p


Pardon the threadjack, your build made me miss my rlp.
post #249 of 330
Ahh memories...that was the last sub I had (in car) until it was stolen. I had a 10" Orion HCCA a couple years back and everyone thought I had dual 12"s or a 15". Those old HCCA's had some major kick!
/threadjack

Close to having the second RL in it's new home yet? BTW I am curious...what has your GF said about all the amps lying around?

I had some HCCA stuff a while back as well (long while, like 18 years ago). It was some of the best stuff around at the time. In fact, I worked for an authorized ORION dealer. We even had our own 15,000+ watt sponsored custome mini-van, back then it was some serious stuff.

She's out of town and hasn't seen all the amps, but she already knows I'm completely out of my mind. I even went so far as to tell her it will require many, many power amps and subwoofers to comfort me in her absence.

The second sub box is awaiting polyfil and holes to be drilled for the driver and the terminals, then the top panel will go on. I am planning to do all that TONIGHT actually since I am both child and girlfriend free for the next two nights.

Did she say cut the BS or did she say "Ahh your so sweet"?

For some reason I picture you in your garage tonight humped over like Smeagle saying "My precious...My precious". That and (if your avatar is indeed a pic of you) looking like a crazed Gene Wilder with red eyes from the paint fumes half high and deranged in a white labcoat. Why the labcoat?? Who knows...it just fits.

I think a little of both... sweet and full of sh!t.

The avatar pic is not me. It's from the "Worst Job Ever" video. One of my favorites.

Sadly, I don't have enough hair left these days to qualify for the Gene Wilder/Einstein type... but in my *cough* "formative years" that was a frequently heard remark. Smeagle on the other hand... well... yeah... that's about exactly right!

Wow..I remember seeing that vid ages ago. I completely forgot about it. Funny as hell especially the f-ing f-ing f**kburger part.

BTW what was the OD of your port? I ordered a 8" sono for my port but was wondering what the OD was. I figure the sono is probably 1/8" thick? I am thinking about buying one of these bellmouths instead of routing the port flares to save some trouble and buying a 1.5" roundover.

Here's the site:
http://www.spiralfittings.net/standard%20bellmouth.htm

I am looking at the 9" which flares with a 2" roundover to 15". The ID is -1/8" = 8 7/8". Same with the 8"...ID = 7 7/8". If I do the 9" i can mold the inside of this housing to the outside of the sono maybe and bondo it to smooth the step with reinforcements on the outside. Just one possibility.
post #255 of 330
Just curious... are you going to sand that bondo or let "wind erosion" take care of the rough spots?

The tubing I have is roughly 8 5/8" OD and a little over 8 3/8 ID. The wall is a little less than 1/8 thick. Genuine Sonotube brand will be thicker and have a smaller OD and ID, based on what I examined at the local Whitecap store. There's no real easy answer to doing to the port flares. Either way you have to join the straight tube part to the actual flare in some kind of seamless fashion. If your flare is made of MDF, you can just cut the flare circle to the appropriate size to match the tubing, then use some bondo to smooth over the edge where the two pieces join. If you use bell mouths, you also have to join/integrate them with the outer panel and the inner brace piece (if you flare both ends). I guess the real trick is getting tubing that matches the size of the bell mouth flare and figuring out how to join them together.

You'll need a router to cut your circles anyway, so maybe one of those 1.5" radius corner rounding bits for $60 from MLCS would be a good option. You have to go slow with it and do multiple passes, increasing the bit depth each time, but it comes out pretty nice in the end.

I sanded the bondo down before shooting it with the black spray paint. Not PERFECT but pretty smooth now.

Made some more progress tonight. Lined the box with polyfil, drilled holes for driver and terminals, and finally got the top panel on. Port outlet is looking good after shooting it with some of the bed liner spray.

You have any bass traps in your room btp? You will soon be in the realm of getting the bends like a diver!
post #260 of 330
Brad, the box looks stuffed. You sure it's not too much. You don't have to have any if the response looks good...at least on Unibox.
post #261 of 330
Thread Starter 
It's really not as stuffed as it looks. Honest. I set out to just line the walls but there is some polyfil on the big tube in the middle, so that contributes to the "stuffed" look. I used much less fill this time than on the first one (which has already been "de-stuffed"). If I had to guess, I'd say there's about 3 pounds of polyfil in there right now which is around 3 ounces per cubic foot.

No bass traps in the room... yet.

So tired now. I was up until 2 AM working on the dang thing.

Edit: What I'm really curious about is the tune on this second box. Will it be exactly the same as the first one? Higher? Lower? I already have a feeling I will wind up swapping the drivers between the two cabinets (out of paranoia) just to see if that makes any difference in the tune of either. How's THAT for neurotic?

I was about to ask that because from what I remember he removed most of it from the last box.


BTW why so many alternators???
post #263 of 330
Thread Starter 
Because they were there? Just grabbed whatever I could find that was heavy to throw on the top for good measure, to press the panel onto the underlying network of bracing. I knew at least a few people would get a good laugh out it... 3 dead VW alternators and one dead OEM Audi battery.

Well, thanks to several days of pouring rain here in the Pacific Northwest, my garage is taking on a bunch of water. The GOOD NEWS is that the second subwoofer is resting on a pallet located on somewhat of a high spot where the water hasn't really accumulated. Some of my scrap MDF and other things in the garage have gotten wet, but no major losses. I just need to finish up some caulking and polyfil inside the box now that the top panel is on. Then sand all the seams down and router the external edges. Then it will be ready for paint and/or the driver to be installed. But with this water problem I'm really itching to move it into the house, so the paint might have to wait a bit longer. *sigh*

Quick update: the second box is just about ready for paint now. All the glue seams are sanded smooth and edges have been rounded. But I may not paint it right away. Need to give that some more thought as I wanted to paint both subs at the same time and moving them... well... it's just a serious P.I.T.A.! I think I better invest in a good furniture dolly (AKA "hand truck").

I'll post some more pictures tomorrow.
post #269 of 330
I really like the layout of your subs. They really look great. Good build. I really like the braces and that is how I wanted to lay them out. I think I am going to go that way.

2 of them ought to give you some serious output. Hopefully you finish soon. Good luck.

Thanks, Robert. It was a LOT of work but I'm pleased with the results. You really don't know what you're missing until you get some serious "subwoofage" in place!

Without further adieu, here are some pictures of the TERRIBLE TWINS. OK, so they're not quite as "terrible" or enormous as Scott's, but they definitely rock the house with incredible authority.

And before anyone asks... I plan to paint them both at the same time at a date yet to be determined. I will probably paint them (with the bedliner stuff using a roller) right where they sit as the subs are rather difficult to move. I'll just use plastic to cover the projection screen and floor and anything else nearby.
