StrangeFlavors HT Build Featuring HT8 + Mini Marty + Volt-6

Welcome to my build thread / Journey into DIY. A year ago I knew nothing about DIY speakers and now I find myself frequenting this site multiple times a day, the hobby has taken over. It all started when I was researching what sub I should buy and realizing how expensive they were (for something as small as a 12" at that) and I stumbled across the DIY section of this site. I suffer from analysis paralysis and I had a hard time deciding which DIY sub to go with between the VBSS and the Marty / Johnny but in the end I went with the Mini Marty. Factoring in future additions to the HT and the WAF it seemed like the best option. So my journey begins with the Marty.

My Background
Growing up I was the go to guy for car stereo installations for my friends. I feel like I have a pretty good ear for sound quality but i'm no expert. This is my first dive into something other than car audio and boy do I feel lost sometimes, but half the fun is learning so I don't mind. I'm pretty mechanically inclined and if there is a tool that I don't have, my dad does have it. So I knew that I had the means and the will to complete a project of this size. These factors and my cost consciousness ultimately lead me to the world of DIY speakers. I wouldn't say that I know a whole lot about the science behind all of this yet but I look forward to learning it.

Mini Marty

The Decision - While trying to decide which Marty to build I was going back and forth between the Johnny, Mini, and Full Marty enclosures. I settled on the Mini because to me the Marty's value is the the ability to dig down and get into the Mid Teens Hz wise, and the Mini was the best compromise between size and tune. In hindsight, it's so big already, I'm not sure if I shouldn't have went ahead building the Full, and in the future the next one I build will probably be a Full, unless another design catches my eye. At first I was going to go with some Birch but after pricing it out at a few local lumber supply places I couldn't pass up the savings by going with MDF. So I went to the store, picked up the wood and headed to my dad's house.

Seemed to have lost some pictures around this part of the process so I'll jump right in to the assembly.

I Purchased a circle jig for my router to get the wholes right for the driver. It worked really well.


Used a finishing nail gun and Titebond II for the assembly.


Prior to adding the inner bottom piece I painted the port area black with some left over spray paint.


Everything I cut was pretty square so it was fitting together well.


Used all of the extra MDF to create some bracing.


Mocked up the baffle to see how it all fit together, obligatory curious cat.


Stopped by Walmart to pick up a king sized mattress topper for some sound insulation.


Landed on the NX3000DSP to power it after some back and forth between it and the 6000. Given my addiction I probably should have gone with the 6000. Hooked it all up to give it a test and all I can say is WOW, I'm blown away by this thing.


I used Durhams's water putty to cover up all of my nail gun holes and prepped for paint. I used an orbital sander with some 80 Grit to sand all of the edges smooth.


After it was prepped I pulled out the router again and beveled the edges with a 0.5" bit. Messed up on a section so I used some putty to fix it. I used a smaller bit on the ports.


The theme will be white and black, which brings me to my current state. Here it is routed and primed. You can see a Volt-6 lurking in the background.

I knew I wanted to paint the speakers all white so I went with MDF for everything. Here is how I braced the HT8's.


Made the Crossover board out of some left over cabinet backing.


Stuffed the Volt's with Poly-fill and glued some cheap acoustic panel for the HT8's.



Primed with two coats and then painted with two coats. Tried brush first, then paint gun, settled on a roller in the end.

Next step is to finish my entertainment stand.After that I think I will try to build some V.B.S.S.'s and hide them somewhere. I can tell I'm missing mid ranged bass when listening to music and I think this will solve the issue. This is quite addicting.

Through this process I've learned a few things:
1. At first I thought I wished I had bought the NX6000 instead of the NX3000. Now I think I will just buy the NX6000 and find a use for both. I blame this site for that.
2. I probably should have just went full Marty instead of the Mini. Where it ended up in the room wouldn't have really mattered if it was bigger, and I don't think there would have been any (more) complaints about the size.
3. Practice with the router before going to town. On a second note my water-putty skills have improved tremendously.
4. I made the paint process a lot harder than it needed to be. Roller from the beginning would have probably been alright. The paint gun was much more trouble than it was worth and probably wasted more paint than I used.

I've watched quite a few movies so far and it sounds great. I need to buy the mic and do the final calibration once I'm done with my entertainment stand. So far my only complaint is bass for music. This is an awesome site and I'm glad I found out about all this before missing out on my new favorite hobby.

Compared with the stealth look of the typical all-black HT builds the white cabinets contrasting with the black woofer, waveguide and ports certainly creates a unique, eye-catching appearance. They will definitely draw a lot more attention and I expect some will love the look and some will hate it.

Did you take any extra steps to seal the mdf edges?

All I did was water putty the seams. I used two heavy coats of primer and paint with some sanding in between and it seems to have hid the edges. I went back and forth for a while on this, but I started with painting the Volt and absolutely no edge was apparent so I didn't worry about it. The only seam you can faintly see is on the Marty for some reason, but the edges don't show. This is probably due to me routing around the whole front.

Quick update, couldn't find an entertainment stand to fit my needs so I built one. Now that this is done I'm on to the next phase. I have decided on 4 sets of Volt 6's for Atmos. I really like some of the builds on here of them flush in the ceiling with custom screen covers so that's what I'll be doing.

Thanks! I love them so far, very happy with how they sound just being powered by the AVR.

Thanks! But as far as the close up I don't think you want to see mine up close either. I tried to paint them with an automotive paint gun at first and one didn't fair so well.

@JONA a hilarious. @StrangeFlavor looks good man, good job on the ent center too.



Those HT8 are my next project to replace my c-note and modified jbl center. I used mdf, kilz and then rustoleum oil based paint. I brushed it using a fine oil brush, took about 6 really light coats to finally get the brush marks out and then 2 coats of clear. They still look good 18 months later and no issues with edges, but I do now have a small bump where a nail is possibly trying to back out.



Thanks again for the pics!

I'll have to try this approach on my next project, looks great.

It seems the working from home thing leads to me buying a lot more. 4 Volt 6's have arrived for ATMOS duty. Started making the custom baffles today to flush mount them in the ceiling. More pictures to come. Also picked up some C-Notes and a Tang Band 5" sub for another project.

Finished cutting everything I needed for the Atmos boxes. Picked up a Jasper Jig and it is worlds better than the circle guide kit I got from Home Depot. Starting to glue some things up slowly as some of my clamps are currently being used to build cabinets. The boxes will be the same volume as my surrounds. I have the round portion coming out 1/2" to sit flush with the ceiling. The only thing left is to cut is the covers when the screen cloth comes in. This is my variation on what @trevordj did with his Atmos speakers. His came out awesome.

StrangeFlavors HT Build Featuring HT8 + Mini Marty + Volt-6

Right on! The way you are doing it is definitely much more efficient than how I did it. The way you are doing it will make it so much easier to mount them too. Nice job with everything the white boxes look great.
