EDIT: Sorry to hijack your thread but I figured this would be the best spot because you actually have one of the drivers and could be relevant to you as well.


Are you building enclosures for the HT1 subs that we are talking about here? Where did you get the measurements from?

Yep. Since the HT1 is based off the SSD and the HT2/3 are SP4, I looked at the dimensions on the Fi website and they're the same. So I figure I should be good to go with the 16.75" it says on their site.

That makes sense, but I won’t know for sure until this weekend. I am starting my boxes but I will do a quick test cut on some scrap wood to make sure 16.75 works. I am not going to inset mine but I did put a tape measure across the top and it was right at 18.5 inches wide

Got everything cut up. It's been a while so I hope it's all correct. I used 4 sheets of MDF instead of 3. Doing this allowed me to make about half of the cuts for both boxes at the same time by stacking the sheets on top of each other when using my skill saw. Did all the skill saw cuts first of course in order to get them to a manageable size for my small table saw. If you see any mistakes let me know.

Lol it's definitely taking longer than I thought it would. Should have them running this weekend and hopefully will get some videos up too.

One trick for guys reading this thread when I build my boxes I make the sides 1/4 inch bigger than what they need to be so this way once you lay your top piece of mdf on top you can flush trim bit what ever is left over. The reason why 1/4 is because sometimes the front and back cuts are not exactly spot on and glue might add 1/32 and throw some stuff off every once in a while. It’s happened to me so having the sides be a tad bigger helps out.

This is great advice and I should have done this on my build. Luckily I did a dry test fit of the front baffle and it is a little too high which raised the top up. I was able too fix it by trimming a little off with my skill saw but that was not easy to do. I just picked up this jig to make the cut on the other baffle a little easier.

Why didn’t someone tell me that these things weigh as much as a refrigerator when they are completed . I made a few small mistakes but nothing 60 grit sandpaper and a little time couldn’t fix. I picked up some Forearm Forklifts from Home Depot but will have to wait until next Friday so my friend can help move them.

What was the tune of these cabinets?

I dont remember if you said. I saw 17hz 10cuft somewhere but dont know if you built that or another design.

Should be 10cuft and 17hz as far as I know. I just build the minimarty cube that is on the first page of the FAQ thread. I will have to use the high pass filter of my Crown and it only goes down to 30hz, so I'm sure that will affect things until I get the miniDSP.

Is it Saturday yet??? Those are some sharp looking subs and that's what I am planning on purchasing for my brother's build this summer over the UM.

Deer Creek Audio is a good guy; got my MiniDSP from him as well. I wonder if he is on AVS?

I too will be hopefully doing some tuning with the MiniDSP and REW this Saturday. Good luck and enjoy the process. Don't rush things (like me) and screw something up (like me).

Super quick short version, upload the plug in to the MiniDSP using your computer before connecting to amp or AVR.

Don't be worried!

Hahaha, well I talked about the issues I had mounting my subs on my thread... almost lost a finger! Gravity, close tolerances, heavy weight, and a lack of much to hold on to. What hardware are you using to mount your subs?

Then REW & MiniDSP is a learning process, but well worth it. Still scratching the surface with them myself. Absolutely amazing what these tools are capable of together.

That does sound bad. I will just be using some wood screws, one box has wood blocks for reinforcement and the other does not. I'm not doing a recessed mount so I hope the 1.5 inches of MDF will work on the one without blocks.

And do the old zip-tie trick with a couple of the bolt holes when you are ready to mount. However, make sure you know the head of the zip tie isn't left on the underside of the basket after mounting, thus making a leak and sounding particularly flatulent at the 30Hz and below range. Another one of my lessons learned. But it was an easy fix.

On the MDF only just be careful to not over spin the screws. Go really slow with the drill and use a low torque setting. Pan head screws recommended. I used the kreg pan head screws because I had them on hand.

Got them up and running. They sound great to me but I think my wife thanks I’m crazy, she said it was rattling things in the kitchen. It did create one new problem for me, my screen. I was going to buy a new one soon but these things are so big that I now have to so things will work together space wise.
