Re-finishing these enclosures is taking longer then I had anticipated...
Stupid roundover edges are difficult to curve the veneer over, I should have gone larger then 3/4"

Well, this is fun...


I get to travel for work - again! Too bad its not exactly a tourist "hot spot"...
...in fact I doubt anyone would want to go there - even the people that live there are trying to leave...
(of course, that's why they are sending us)

This is gonna be a "fun" couple of months....

Living with Monsters...

After a little while with these beautiful drivers, I figure I should do a bit of a review...


24" subwoofers are unlike anything out there... You need some planning in advance, as moving one isn't an easy task. Make sure you get things right the first time, because trust me when I say pulling the drivers is a PITA!
That having been said, they are simply wonderful entities...


The way the drivers simply loaf along while destroying anything around them is way too much fun for words...


Some things I have learned
1. Sealed subwoofers are special. I have spent time with a few different alignments over the years in a multitude of different applications - and much like horns, sealed subwoofers seem to have a presence and impact to them unlike other styles.
2. These subs really would like more power then I am feeding them in their current habitats...
3. Listening to inferior setups really sucks now....


I have to say, its hard to watch movies, cause I don't want to turn off the lights! Watching these things jump in and out/back and fourth is mesmerizing....


Im going to miss these while Im away....

Good luck on your travel. I just got back from some work travel. It got me 5 days in the hospital, and another week recovering at home. Definitely not work the hazard pay. I haven't been able to work on my theater for a few weeks now, it's driving me nuts.

The sound that comes off the front of the speaker cone is exactly 180 degrees out of phase with what comes off the back. So the signals cancel each other out. The purpose of a box is to keep those sound waves from reaching each other.

Sorry dumb it down even more. Are you saying that boxes attenuate some of the frequency that goes out the back?
thanks man

Sealed subs attenuate all of it. Vented subs use that back wave and with a proper port length and design, shoot it back out into the room to boost the bottom end of the system, but if you look at a phase graph of the response, you will see a shift right at the port tuning.

Yes. In addition to what Beast said, that's why they have to be built like brick *****-houses.

Actually, Nick and I discussed the regular vs. BHS versions, and agreed that the HS-24mk2 versions were the correct drivers for my application... and if I needed more (Nick just laughed at the thought ) it made more sense to add additional drivers...

Well, its been a few months now....


I still love these subs... I get a big freaking smile every time I walk into the room (I honestly thought that feeling would have gone away by now.... but there is something about a pair of 24" drivers is just wicked fun)


Im getting the itch to build something again though.... maybe time for a nearfield setup?
What are the current best "budget" 18's avail? Still the Dayton Reference or Ultimax? or has Nick got the new HT18's out yet?
I have been away for a while.... with no internet access (well, very VERY limited)

Did you get the quilted bubinga veneers on? I am going to be a building a DIY sub somewhere between a Marty cube and mini Marty, and I also bought a quilted bubinga veneer for the cabinet. I'm curious how yours looks since I would also be doing mine satin with no stain.

Sadly no, not yet... Had to head outta town for a few months for work.... Might re-visit the veneers in the spring, I'm looking for a quick and dirty build of sorts right now...

Anyone else see that coming? The "my dual 24's just aren't quite ENOUGH" club is getting another member.

It should be noted that I have issues.... and most sane people would be more then satisfied with a single 24

Ok, so it looks like the only "budget" 18's available are the Daytons....


Is it worth taking up an extra 8ft^3 to go with the Ultimax Drivers instead of the Reference? (4ft^3 vs 6ft^3 per driver?)

I'd center the drivers, unless you have a good reason not to. Also, if you have some way to EQ out, you could go smaller with the ultimax, around 4-5cuft should suffice with a small LT on the bottom to drag up the response a little. Would lose a shade of efficiency, but not much from 6 cuft.

I can center the drivers for sure, only reason I had them along the bottom was to avoid the enclosure rocking - but I could always bolt it to the wall if it ends up actually being an issue...
EQ is no prob...

Don't think youll have an issue with that much weight, assuming it is well braced.

I DO however like the thought process going on here:

"I love my 24's but I want some nearfield action"

No let's not just do an 18 or two.

"Im going for 4 more 18's and rupture my spleen in the process"

Yes, I like the thought process completely. It is beastaudio approved

Seeing as I started right of the hop with a pair of 24's.... this just seemed like the most logical progression...

agree, no issues with the enclosure rocking if it was around 24" high.
Have you a dual opposed design? takes rocking completely out.
Also, I believe you should go with UM-18s or a greater driver.
I wouldnt wait for the new HT18s if you're only adding 4 subs.
