i got started on these a while ago. i assembled the flat packs in less than an hour total with just Tightbond II and a brad nailer.









i patched them up with drywall mud and then i decided to do a 1/2" roundover on all the edges







This driver is pretty impressive for $62 delivered





WARNING!!!!!!!!!!!!


These flat packs were ordered with the cut out for the Dayton RS 12" driver. I read in the reviews that this Infinity fit perfect. Well, it fits too prefect and got stuck when i test fit it.



This resulted in having to damage the box a little bit to get it out. Then i fixed the box with some Tightbond mixed with MDF dust and sanded it smooth. I would recommend either contacting Erich and asking if he could do a custom baffle or routing the opening out another 1/4" or so at least. If your ok with them being that tight then dont put them in until you are totally done and wont need them out again






I love Duratex. It only takes about an hour under normal conditions to be ready to recoat. I get a good amount on the roller, stuff it into a freezer bag, and tie it closed between coats. i didnt even have to use a roller pan. I just rolled right out of the bucket.





Duratex is done. i set them in their planned positions for now and ran all the wires. im still waiting on the terminal cups.











As for how i have these wired. I have the iNuke on a shelf in the basement. I didnt want to deal with the noise. My AVR does not have a 12V trigger so i used something called a power bridge to run the AVR power cable downstairs.

then it plugs into whats called a Smart Strip. The iNuke and a ART Clean Box Pro is also plugged into the Smart Strip. They both turn on whenever i turn on the AVR.

Is there really any reason to take them out except to replace them?


Be sure to run some tape inside the woofer cut out or the duratex will make the opening even smaller. Maybe hit it with black spray paint to make sure there is no bare MDF to see.

i think i will use these terminal cups. this way ill be able to get something in from the back side to push the driver out should i ever need to remove it.

I bought these and love them. They have a soft foam gasket on the back. Warning, the gasket gets a little sticky when you put it so with this make sure you are ready to put it in permanently.

Looking great! Do you have something to compare them to when they are up and running? No doubt they will sound great and looking forward to your opinion. Just wondering how they sound compared to a store bought or other home build.

I don't have anything here anymore to directly compare them to, but I've had a few other DIY and ID subs. I'll do my best to give a subjective opinion based on my experience with the other subs in addition to the measurements.

Can you give a quick opinion? I need to order something soon and this was one option.

Would you care to comment on why you went this direction, considering the impressive DIY gear you've had in the last year or 2? WAF? space? If it's none of my business, that's fine too and I apologize.

We moved recently and I do not have a dedicated space for big subs.....yet



These are going in our great room that has a pretty modest setup. Pioneer Andrew Jones up front. Polk monitor 30's for surrounds.


I wanted at east two subs but I don't want to spend much in this room. And they have to be small. So that's the motivation here.


As soon as I get permission to start on the basement I'll be going big again. I promise.

So slightly north of 500$ for 2 subs inkluding amp and finish. Not bad

And don't forget DSP as well!
