Nothing fancy. I built these about 6 years ago for my wife's Beomaster 1900. It is a set of Polk DB6750's (a component setup with 6 3/4" woofer and 92dB sensitivity). 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.

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.

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

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

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?!

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.
