What do you guys think... Fusion-8 Alchemy or Alpha-8 Minion for side surrounds?

Do you think that these will integrate OK with my B&W fronts? I will eventually replace the B&W's with Sentinel's.

The first of two 18" 4cu ft flat packs is built. WOW... I love this thing. Awesome work, Erich. Thank you so much!

I also love my air compressor and brad nailer. I built this box in about 30 minutes. Glue and brad nails. No clamps needed.

Am I stupid for wanting to setup the driver and use the sub before sanding and DuraTex?

Do people use any wood fillers or anything for the corners or outside seems? Is any needed or does it fit pretty much perfect?

they fit pretty close to perfect, you can use filler to fix any assembly issues. just sand before you use filler if the seams are not 100% even

I sanded all the edges and primed. I will use drywall plaster to fill a couple brad nail holes and one edge. I'll then sand and re-prime.

Guys, are there any other subwoofer boxes we should look into? Or any other woofers for the 4 cuft boxes?

do we have a dual opposed 15 yet?
make it more square vs rectangle like the current dual opp designs on the site

It wouldn't work very well having a square box that big. Figure a sheet of mdf is 49" wide, then subtract of a 1/2" bit that goes around each piece. That leaves a 47" width to get 2 pieces from. You can't get two 24" wide pieces cut next to each other. So a 23.5 cube is only 6 cuft gross.

Erich do you only build sub woofer enclosures, or do you also do speaker enclosures?

I need to get off my butt this weekend and start building my flat packs for the 18 SI that i've had on preorder...
Anybody heard anything about when they would ship or even if they gotten them yet?

Speaking of building these flatpacks....any recommendations now that a bunch of people have built them now?
How are you doing your cable plugs/feets and such?

I have the Titebond glue and 6x 42" clamps
Wasn't sure what type of screws/nails to use yet so haven't bought any yet.
Also was reading something about Polyurethane construction Adhesive (Glue and seal your box in one step) ... anybody with experience with this stuff?

anything i forgot?

I would just use Titebond wood glue. I have some photos showing the steps to follow for assembling those larger 4cuft boxes on the product page. I think they go together easier that way, but some might do it differently.

I should have directions for all the boxes done in the next week.

titebond is so much easier to work with vs PL Premium (the construction adhesive)
there are a bajillion pics in my build thread in my sig. im not sure you even need to seal the seams with the rabbit joints. i did with PL because i like overkill.

Just take your time and try not to glue too much at once

i did it like this and it was pretty simple

Rib Braces into back
Top and Bot
1 side
inner baffle
other side
outer baffle

I used Elmer's Wood Glue. I sure hope that was OK. I just realized that I forgot to buy feet.

How air tight are the sealed boxes supposed to be? Should I run a bead of glue in all the inside seams?

As long as all the joints have glue it should be air tight. You can fill the inside seams with glue but overkill really...

Have you ever considered a 3 way? OSWG or cd horn, 8" midrange and a 15" or 18" woofer in one package? You could get 20-20k, low distortion, great sound and work on a watt or two.

Elmers is fine. If you believe you may not have a good seal, use silicone or calk. But, if you use silicone, let it cure for a couple of days before installing your driver(s).

Hot glue to fix leaks, dries quick no fumes.

Dual opposed 18". I would've happily spent more for such instead of the 4' single 18" box in retrospect (not that the box isn't awesome).

Man, that will be one huge box. Shipping might be prohibitive.

I don’t like building multiple subs. A single is fun but anything over two becomes work instead of play. That’s just me.. just sayin.

does not have to be perfectly square just not coffin like

something like 18"W x 23"H x 25"D would be a good shape and about 6 cuft which should work for many 15" drivers


however im not sure it would work based on MDF sheet dimensions

Besides applying Duratex, my two 18" subs are complete. I tested them today with Thor and Transformers. The only calibration I did was with Audessey. I'm blown away. My old sub was a 100w MTX 12". It was very boomy and just made a lot of noise.

I'm not sure how loud it actually was, but my Denon 4311 volume was set to 0db. While watching a scene in Thor, a piece of plaster from the ceiling fell onto my shoulder. LOL

When my wife came home, I was watching Transformers. She came in and said she could feel the bass while sitting in the car in the driveway. No way, I said. I still don't believe her.

I need to figure out how to properly calibrate these subs. Audessey wants to turn the subs way down. What has me worried is I was seeing the red clipping lights come on on the NU6000 DSP.

^^^Parts Express shows they are sold out of the 4 cu ft flatpack for the Dayton, looks like a lot of people are going the flatpack/dayton route! Great to have such easy way for people with the time or tools to still do DIY (ie AIY as I have seen it described here). This is a great thing....(not the sold out part, rather the creation of the flashbacks).

They're sold out because the woofer was sold out even before I took them the boxes. I didn't take them very many to start things off.

Stereo Integrity should start shipment of the HT 18 D2 and D4's today if everything goes as planned (read on another forum), really looking forward to receiving two of them myself! smile.gif

Very cool to see the flat packs on Parts Express.

I measured the clearance I have last night to try to build myself a MTM alchemy center.... just under 10". Sucks.
