I know the Ultimax is currently backordered and I've been asked several times about an alternative. The HO also models quite well in the hammer enclosure.

The plate Amp the hammer can be cut for. Other amps can be used including amps like the Behringer NX3000 with one Hammer per channel.

Video quality is much better.
Something to note.. when you have more lighting (like toward the end of the video) it looks much better.
Looks like the camera is struggling in the lower light at the first bit of the video.. looks like it's sacrificing frame rate & introducing some smoothing, to maintain a brighter image.
Great stuff! Looking forward to seeing tests, and more of your room when you get to it. :)
I had ordered two soft boxes and they came in during the mid point of the video. That's why the 2nd half has better lighting.. 😁
I have frame rate locked but did have the iso jacked up in the first half.
Nice to see you back pal.
Thanks, Still waiting to get started on the house build so I may as well make myself useful.
Home Theater Gurus Ya don’t blame ya at all.
As always, your videos are very good on explaining.
Thanks!
Nice detail as usual! Thanks for putting this info out there for folks like me.
You're welcome!
awesome video...i didnt know that about crimping the wires learn somthing new every day...
Thanks John!
Great video covered every thing in detail.
Nice one, looking forward to the next 2 videos 👍
Does the shape of the subwoofer cabinet matter? I understand we need a specific internal volume... Most subwoofers are short but deep. Can we get the same results with a cabinet that in shallow but tall as long as we keep the internal volume the same. These will be SEALED sub woofers.
Yes better video quality 😁
Awesome! My old one didn't even have auto focus in video mode.
Finally at this stage and I noticed you used a 1" screw when the plywood is 3/4". Not sure of the driver hole bracket is 1/4" but is there an issue if the screws go thought the wood?
TIA
No issue at all. The sub is still air tight.
@@hometheatergurus nice, I will use 1" screws as well. Thx again.
How about polyfill for the cabinet damping treatment?
Great job again! I’m now addicted to your videos!
This driver is BO...😢
Can you suggest another or this one is the best and I should wait until March!?
Thanks! Yeah I 've heard its out of stock. The Dayton HO also modeled well. Not as good but close. www.amazon.com/gp/product/B003XFJ3FM/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=hometheate06f-20&creative=9325&linkCode=as2&creativeASIN=B003XFJ3FM&linkId=43381f7d9472c3ab4fbe1477874f5c11
@@hometheatergurus Thanks!
How’s the new theater coming along? When will you have any build videos coming? Cool!
We're breaking ground as soon as these hurricanes move out. Hopefully next week. I'll probably do weekly updates once that happens.
Cool! Looking forward to it.
Hey man great build, I built this same setup but my sub sounds real flat or quiet at 40 to 60 h. My insulation is a little thicker than what you put in, does that affect the sub? I used mineral wool 3 1/2 inches thick. I used REW and the mini dsp hd and it has a big dip at 40 to 60. Any suggestions as to how to fix this? Thanks
Was it a hammer or just a similar sub? If it's a hammer or another well deigned sub you're just sitting in a null or the subs are out of phase.
See ep 9, 11 and then maybe 7 if you wanna get real serious.
@@hometheatergurus yes it is the hammer. I only have 1 sub at the moment. Do I still need to phase if it's only 1 sub? I've watched those episodes but I'll have to watch them again
If it's just one sub you're sitting in a null. Ep 11.
Instead of the string method, just flip the woofer upside down (magnet out), Then predrill them holes. Great video, quality with new cam is great! Looking forward to the next 2 videos
Thanks and great I think it's better too. My old camera was definitely struggling.
Is the binding post bridged so you can connect the mono cable from the DSP to either terminal? Thanks!
It's a positive and negative. Those are never bridged as you'd ground the positive. You'd need 4 posts to bridge posts but we have one driver who's coils are wired in the video with two wires each connected to a post.
Looks awesome man. I want to know what you think of the sound quality.
It's probably one of the best 12s I've heard. Hits very hard and is very clean.
The 12" driver is out of stock everywhere. Any thoughts about putting the 15" in a similar box for more output and more low end? Or would the box have to be much bigger?
The um15 needs a much larger box. If you model it you'll see it requires such a large box you may as well do the 18. If you stuck it in this box you'd lose performance.
What's the difference between a car subwoofer driver and a home theatre subwoofer driver? All I see is that the car subwoofers use 2 voice coils?
Where have you been? Looking forward to your next video.
Been busy but I'm still here. Have a few videos about to drop and soon we'll start the theater build updates.
@@hometheatergurus awesome can't wait
What are your thoughts on running a um15 in this box??? I’d be very curious what you have to say!! Thanks for the awesome content!
It won't perform well at all. The UM15 has the same motor as the um12 but requires a box almost as large as the UM18. It's kind of an odd duck as you'd think the enclosure size would model in between the needs of the um12 and um18.
Lol, threads. Screw threads, not ridges. The words you were looking for matching the screw to use is major diameter. Technically, you'd want to use a pilot drill closer to the minor diameter (thread root) to ensure the threads engage into the material.
Thank you for the correction Mr. Screw term police 😁
Moving into my new house next month, and building a sub is going to be my first project for my home theater!
Awesome. You'll never go back!
Just ordered 2 crown Xls power amps after our conversation for my front LCR
I have one sitting waiting for the new living room in the new house!
Which Crown XLS? I'll be using two Hammers. Sorry if this is a dumb question I'm new to the diy
Is exohide a darker black than Duratex?
When are the new Theater build videos starting?
The concrete foundation is poured so it won't be long before I start doing go-pro style updates.
Looking forward to this, will be great to see all the build stages, sub floor, riser, stage, walls soundproofing, fabric panel walls etc etc
FANCY strippers! Woohoo!
How DARE YOU assume their gender!!!!!!
Guilty! 😁
