I wish I would have known a forum like this existed when I built these. I used an online program to help me with the box size and port length. A tech at Polk was kind enough to give me the details of the speaker I needed. IIRC, I turned the port to 40Hz.
After what I've read here, I'd likely have done a number of things differently. They do sound pretty good though.
cool looking drivers!

Finished the NAO II RS kits a few weeks ago. They sound awesome, but now I've got to upgrade my subwoofer setup, as my old Titanic ported build isn't quite cutting it anymore.

I'm going to try and build a dual sub box to house 2 12s possibly ported
post #1024 of 1121
WOW!

What a great Thread, i finally reached the latest page. Big Compliments to you all, great work!

This is my System:


I listen primarily to Music (Stereo), but i use an AVR, so I can also watch films and have a little "Surround" (4.0, two little speakers in the Back, the DIY Kit "Needle", two Tang Band Speakers)

My Speakers are called "Triptychon 2.0" and are a new Version of a DIY Kit from "Blue Planet Acoustic" (http://www.oaudio.de)

The mid-high speaker - sections are connected via a conventional but simple passive crossover network to the AV receiver.
The pre-outs on the AVR run in the DBC12. Here the DSP adjusted the sound to the room and runs via Y - cable into each of the XTZ amplifiers. As a result, for each of the 4 bass units, a single channel is available.

The speaker enclosures are made from 28mm HQ-MDF with many bracings. The feet and the terminals are hand made from solid stainless steel from a fellow professional mechanic.
The paint is applied by a fellow professional varnisher.

The crossover is due to the optimal interaction of the midrange speakers with the ribbon tweeter a 12 db Network and mostly built with Mundorf-Parts.

I'm afraid my English is a bit rusty, but if there are any Questions feel free to ask smile.gif
I'm also happy about tips or any advices.

Excellent system Hendrik_B!

That's a fabulous tweeter. Wish there were more builds with the neopro5i, but how many folks want to use $300 tweeters?

@ mjaudio: Thanks! smile.gif

@ looneybomber: After using soft domes and metal dome tweeters, i finally got addicted to the clarity and detail of ribbon tweeters. Fountek has built some very interessing products, even the "small" Neo CD3.0 is a very good one (~ 100$). But for my project i wanted the NeoPro5i. I simply love this speaker. wink.gif

That figures... The video was approaching commercial quality.

My current front stage consists of 8 Stereo Integrity 18's powered by a LG FP14K Clone. Still working on completing the boxes for the 8 subs that will be going behind my seats. Here is a preview:



My build thread is in my sig if anyone wants to check out additional pics and progress updates. biggrin.gif
post #1034 of 1121
It's funny looking back 7 years ago at some of the builds! I remember when a few of us were using the 2kw buttkicker amps for our subs because there really wasn't much else available for the $$$$, and those were overkill.

I also remember the first murmurs about the ep2000, and how we would all finally have all the output we could possibly need!!!

Fast forward to today....14wk amps.... 30 cubic foot horns..... High sensitivity waveguide kits in-a-box..... Drivers capable of moving GALLONS of air.... Computer aided room equalization.... And whispers of 11.1 master audio tracks and dedicated transducer channels...... Will it ever stop?

How can you ever overcome and addiction if the drug keeps getting better?!

Just finished a set of speakers...Bi-amp, push pull, OB. Finished in ebony. Mostly Polk drivers (MW5530, Eosone 10 inch woofer), and a CSS Tweeter.

My current setup...



The subs, pedestals for the towers, and boxes for the surrounds are DIY...

I have a question, Is it ok if I add another port hole on my cabnet? will it effect it in any way such as sound quality or bass? I want to put the other port on the right side just to even things up.

Assuming it was properly engineered to begin with it will ruin your speaker.

Agreed.

If the appearance of a second port were desired, it might be OK to add one and block it firmly on the back side with a black-painted piece of MDF.

Hi all. Figured I'd share some pics of my first DIY sub project. I don't have a build thread like some of you, so I'll try to be as brief as I can be.

The box was originally modeled with WinISD at 9 cubic feet. It wound up being 7.827 cubic feet with bracing and is tuned to 18 hz. The driver is a 15" Dayton RSS390HF. The amp is a 300 watt Bash digital plate amp. The port is a flared 4" dimpled Precision Port.

Below are some pics of the process. During the build, I did as much as I could do, alone and without any prior knowledge. These forums have been extremely helpful, so for anyone considering a similar project, the AVS forum is a great resource.



Basic box construction using coarse thread drywall screws and Elmer's carpenters glue.



If I were to do it again, I would have started with the legs! I got this idea for bracing from my neighbor. The legs are standard white pine posts that I bought from Home Depot. I know it isn't standard bracing (mid-box), but they work amazingly well and eliminated the need for feet and additional bracing.




Front and rear cutouts.



Stuffed with mattress foam, painted "cannonball" black with a textured roller, driver and amp installed. Legs and trim stained red mahogany to match room decor. It currently doubles as an oversized end table and my wife ACTUALLY likes it.

Comments and questions welcome.

Been a year in the works, and as you all know, never quite complete. Saving for some new speakers and receiver to upgrade from the current 5.1 to 7.2, cant wait! Pics below show bits and pieces throughout the year:

 

This was the first attempt at a painted screen, rush job but it sufficed for the better part of the year.

the lighting is terrible, i felt like i had never left work so these tube lights didnt last long, as youll see...

added a homemade bar, to help with the lack to seating, old barstools the previous owner

had left behind, those were quickly changed out.

At this point i got bored and started ripping things apart and making some improvements, first step, ceiling and lighting.

bought a cheap paint sprayer and blacked out the drop ceiling and added some led recessed lights on dimmers.

This step alone made the basement feel more like a theater, plus cut down on all the glare on screen. 

with the ceiling done, took some time to finish up the bar with some drop lighting, and worked on the decor. 

the pennant lights are actually track lights, but with the included ceiling covers you cant tell, 

worked out pretty well. Found these at HD on clearance.

although it is hard to see, i found some movie quote stickers online,

really helped to fill the gaps on the collage wall.

for some reason, I didnt take pictures during the rebuild of the screen, sorry.

I realigned the screen so its centered in the wall, and made a double frame to allow for the led lighting to fit behind it. 

The original frame was just 1X2 with felt stapled over it.

The one pictured below is a 1X2 frame followed by some base board, painted flat black.

The leds  behind it run off a remote so any color can be picked. Found the strips on amazon

for $30, really accents the new screen in my opinion

the blue doesn't look as good in pics as in person, but its my current favorite, esp against the dark blue walls.

installed some led walkway lighting leading into the theater so the amateurs don't turn the lights on and ruin my movie

another amazon purchase, motion activated and only stay on for 30 seconds so they don't become a distraction.

(the amp on the right side of the entertainment stand runs the 2 bass shakers in the couch. really helps to immerse you in an action movie.

explosions are on a whole new level!! highly recommend!)

what started as a shelf for the few blurays i owned has quickly become an addiction,

a few more and Indiana has to find a new home!

although im not convinced on the benefits of power conditioning i got one of these things

just becuase i plan on having an in-wall rack eventually, and this is easily stack-able. 

Also ran cat5 to the basement with a 8 port router so everything is hardwired and have room for expansion.

 

 

Will continue to update as the new toys come in:

 

 - in wall rear and surrounds for the 7.2 setup

 - receiver

 - thinking about BIC speakers for the center and mains. 

 - still undecided about the subs, but open to recommendations. (I prefer to buy over build when it comes to audio)

nice setup. However this is a thread for DIY speaker and sub builds, not theater room builds. You may want to move your post if you want feedback on items for your room. Especially if you prefer to buy over build. This isn't the place for buying. smile.gif

Great job on the finish and the aluminum trim around the grill looks sweet!

Nice looking shop too biggrin.gif
post #1049 of 1121
Agreed. The metal trim gives it a retro feel, but it also feels very new and trendy. Great build!
post #1050 of 1121
+1 very nice - do you have a thread on it? (couldn't find anything) I'd be interested to know a bit more about the drivers etc
