Yea cardboard shipping tubes, we get them by the ton at my company, .15" wall thickness and perfectly round, they glue solidly to any wood baffle (unlike PVC), I use them in all my builds. Thanks for following!

Thanks! It's a fun theme as the attention to detail doesn't have to be as good as my usual build, and it follows the older horn concept.

Interesting, I bet it glues better because its porous but my experience with glueing PVC was never bad. It is just difficult to get in place.

It looks like you cut out a groove for the tube with a rabbit bit and a massive bearing lol.

I'll have to try this on my next build!

Good work as usual.

Yea it's made from wood so the bond is permanent, and it's free and very easy to work with, thanks for the kind words!

How difficult was the mid horn build? It would seem that the angles would be tough to figure out on your own. Did you have a set of plans to go by? If so, how could I go about obtaining a set of these plans? How much do the plans cost?

Yes it's tough, much more complicated than the average Speaker Build, but doable. You can get "plans" from inlow sound.com but they're just dimensioned drawings and cost $25. I came up with my own way to build them from what John suggests as it allowed me to make all my cuts in a sliding chop saw, now that I know how it's quite easy but there was a few weeks of head scratching as I wrapped my brain around it.

Let me know if I can help,

Out of the clamps this morning, 2nd one in the clamps and 2 more to go. I'm letting the Loctite cure for 12 hours as the pallet baffles aren't perfectly flat and do load up a little when clamped.

You should upload some music with singing in it.

Singing is much more revealing.

Unless you are a violinist or trombonist or something, you'll never notice anything off with such music.
The timbre and/or harmonics could literally be off by 10db or whatnot, and we'd never know it.

Unless you are a hardcore Bach listener who just happens to visit this specific DIY site and open this particular thread, or happens to stumble on it randomly on youtube; THEN you might be able to form an opinion on what is heard.

The only time I've typically listened to classical is when my grade 3 teacher used to force us to do it during reading hour.
I'm not sure what most of the students were thinking at the time, but I'd bet half of them were like... (FML!) on the inside... hehe

Preaching to the choir, check out my YouTube channel, mostly music with vocals on all my speaker videos,and I voice every crossover I do with female vocal music.

Once I have this system back together I'll upload some nice Jennifer Warnes for you =)

Thanks!

Work continues! These showed up, and a damn nice driver for $90!







Tested out my port tuning, spot on!





One port blocked 24hz



Both ports open 32hz



Model for both, 12db XO at 110hz included, 250watts



Port velocities more than acceptable for both configs, both w/in xmax or so

1/2" Round over on ports and 1/4" roundover on baffle driver opening





And I had a special helper =)





Thanks!

That is now hers and will be known as castle baby kingdom.

But seriously it looks awesome.

Won't the round over mess with your tuning? Why not test after the round over?

Haha, yea she's hooked now! The roundover on the port? They are rounded over now, and it's only 1/2" so figure it's like a 1/4" change in port tube length, negligible but tuning is right where I want it even with the round over.

Flushed up the baffle





And 45 degree bevel on all edges



And where all 4 stand





Next step is some sanding and filling, some more detail work and finally a few coats of Danish Oil.

Since these subwoofers will be configurable in dual opposed or stacked, I made some brackets to connect them together in different configurations.

Here are the pieces cut and beveled



Holes drilled for fastening knobs



Fixture for transferring mounting holes and spacing brackets the same



Threaded inserts used on the inside of the enclosure, these are M8x1.5mm



Test fit, dual opposed







And stacked, dual bolt patters allow both configurations





Binding posts installed

Looking great! Just say YES to chamfered edges, people!

Hmmmm, kind of reminds me of something... only prettier in your version.

Well, different purposes I guess.

I wish all of my corners had lined up as nicely as yours did. I like the locking method, I've been considering a system like that for my workbench.

You know in Goonies at the end when the pirate ship sails out and the cop says "holy Mary...Mother of God!"...?

Well that's sort of how firing these things up for the first time was like!

First some finishing details.

Rat Rod passive XO, low pass around 125hz







Mounting the drivers







Dual opposed configuration



XO installed and split to top section





Aaaand, wala





Did some quick XO tweaking and ended up with this, bass is about 3-5db down and I'm going to try Biamping to even that out before resorting to active.



Initial impressions...WOW, this is the type of speaker that gives you a physiological response to music, I find my heart rate and pulse raising listening to my reference music. Bass is prodigious, like shake your hair and other body parts powerful, SPL is effortless, I hit 50% volume on my Adcom preamp and it sounded like the house was rattling from the inside out, volumes easily 115db+ at 1-meter, and that's on less than 300 watts or so per channel (Adcom GFA-555).

Fun stuff! Will keep playing with them!

Thanks,
Javad

Probably room modes... The optimal location for subwoofers is rarely where the fronts need to be.
