By the way, if you want to try again, I might have a sample box sitting around somewhere. I can't promise that I do, but there might be one around.

Hey Erich, what do you mean by sample box? I would definitely like to try again, if possible.

There is a company making a filler product gaining popularity amongst automobile customizers, who prefer it's fillers to Bondo's. The company is Evercoat, and it is sold by Ace Hardware. It's like Bondo in that it is a two part putty with a hardener you mix in, but unlike Bondo it is not an epoxy, so it sands much easier. It was developed for the repair of fiberglass boat hulls, and works great with all woods. Evercoat Formula 27 is for use with wood and metal, and is what the car customizers are using. But the one they recommended to me for speaker cabinets is Evercoat Homefix Universal Repair Filler. It comes in two strengths (the stronger contains fiberglass to form edges and span cracks and seams), and in half-pint, pint, and quart sizes. The super-strength filler in the quart size (model no.100773) is $17.99 at Ace, who have it in stock at their warehouse. Your Ace store will special order a can for you---no shipping charge.

I had some rigid fiberglass left over and used that. Should be another good option but a bit more expensive because of the shipping if you don't already have it
post #485 of 934
Ok. I put some PL Premium on the inside. We shall see what happens. Gonna wait a few days till it completely dries.

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


If there's still interest in a dual-opposed 15" box, I think it would make a really great addition. I don't know what it takes to put together dimensions that fit the MDF, or what considerations you have to take, and this is just a crude 5min job to see what happens with these dimensions but I did give room for a 1/2" bit.

17.5W x 23H x 24.75D:



I know you've still got bracing to think about, I think this only gives a piece for the middle like the dual 10" box. But I think whatever fits best would be fine, even identical dimensions to the current 4cf 18" box which is 20 x 23 x 20.75.

Start there and leave the 23" height, reduce the 20" width (since it's a 15" driver) while extending the 20.75" depth as much as you can- wherever that happy medium leaves us should work fine.

These 5.5-6cf gross boxes should be fine for dual 15s, provided you bring enough power and EQ to the table which is ideal for a sealed setup anyway.

Thoughts?

I do have the design for the dual opposed, they just haven't been cut yet.
post #488 of 934
What happened with the 18" or 15" ported designs?

Are they still planned or was it logistically prohibitive?

Hey Guys, which screws do you guys usually use to connect the sub? My sub is the Ultimax 15.

Also, when putting the Acousta Stuf polyfill, do you just stuff it in evenly or do you guys actually glue it to the inside walls?

Thanks!
post #491 of 934
Just stuff it in
post #492 of 934
Ok cool. Thanks. Any help on the type of screws?

I just finished my SI18 build sans paint. Amazed at how much easier it was to EQ with BFD than my SVS PB-10.
I tried gluing some foam to walls with spray adhesive. But when I test with REW, up around 105db 1m from sub, there's a lot of flapping sound.

I will remove the foam pieces and leave the polyfil.

If you want to go with bolts and threaded inserts instead of screws, and your driver can accommodate 10/32 bolts, I have 16 black oxide socket cap bolts (10/32 X 1.5") and inserts with flanges (10/32 inner threads X about 3/4" length) you can have for free (they're slightly too thick for my driver's mounting holes). Just send me five bucks for shipping. PM me for more details , address, etc.

Any plans on moving forward with the 15" or 18" ported designs?

Yes, they are coming, I have prototypes for all of those designs. It's pretty expensive to get them all cut in decent quantities, especially while I'm working on the SEOS-15. But it's getting pretty close to the cutting time.

There was some left over JBL stuff from the group buy I helped with a year or so ago. Someone just ordered most of it, so I can take that money and put it towards the larger boxes.

I appreciate how much work this is for so little payoff so I don't mean to sound ungrateful... Do you have any idea how long it might be until they are available?

I'm deciding is 2 12s would work or an 18...

Or if I should sell my jtr captivator and get some sealed 18s

Any chance there will be more Overnight Sensation birch flat packs?

What about the 0.75 cu.ft. sub?

Parts Express has a lot of those OS boxes, but their kits are out of stock because they're sold out of some of the parts needed for those speakers.

I've got plenty here as well, but didn't list them because of the same reason.

I've got the .75cuft sub box, just not listed. I didn't think many on the AVS forum would want a box that small. I did take some up to PE, but I can put them up on the other site if needed.
post #501 of 934
Will we ever see a 2.5 ft^3 flat pack for the Cheap Thrills or should I move on and make my own boxes??

I'm sending some flat slot ports to Matt Grant to see if they will work for his Fusion-15 speaker. That speaker uses a 2.5 cuft box as well. If I can get a design that can be used for multiple speakers, then I'll get them done.

Right now, I'm not sure how many people need the 2.5 cuft box for the 15" woofers now that PE is sold out of that buy out woofer. If I had a better idea of that, then I could talk with the CNC company about a smaller run. But I would hate to cut 30-40 and then they can't be used.

Hi Eric,

PE won't sell the boxes separate from the kit, at least that's what I was told. I built the kit, and parts work fine...So no need for new kits, just need some cabs since I botched the first pair.

As for the 0.75 cuft. box... I know PE has them, but all of their boxes are a fair bit more expensive than what you have listed on your site... which is why I wondered if you were listing them as well.

Is the 0.75 box (well with additional cutouts) the one used for Jeff Bagby's dual passive radiator design with the Dayton Classic woofer? I saw a kit for it - the Baby Boomer - at Meniscus recently?

Thanks Erich, I appreciate your candor and agree with your assessment. That was the sort of response I needed to determine my next move.

Home Depot, here I come!!

To stuff or not to stuff??

 

 

From what I understand the general consensus is to stuff a cabinet with approx. 1 pound of poly fill per ft^3. That said, in case of flat packs I had also read somewhere that this would not be needed. I am looking for some guidance, specifically with a 4 ft^3 flat pack and 18" SI driver.

 

Thanks!

Erich, don't mean to bug you about this again...

But are you also no longer selling just the Overnight Sensations TM flat packs by themselves?

Figured I should check in again...

Any idea on a timeline for the ported 18?

Want to start saving my pennies

A 4cu ft box for 15" woofers is done. Basically the same box for the 18", just cut for a 15" woofer. They'll fit the Ultimax and Reference Series, or most models that don't have that big gasket on the outside frame.


I'm still waiting for the 18" ported/18" dual opposed, but I'd really like to get them done. One issue is cost to get 40 of them done.

Alphaiii, I'll have to see how many of the Overnight Sensations I have that aren't wrapped up. I did take some up to PE last week, so I'm not sure how many I still have.

The 4cu ft box for 15" is single woofer, correct? But you also have something similar but dual-opposed 15" cutouts?
