Hello All,
Following on from Phase 1 - http://www.avforums.co.za/index.php/topic,17108.0/topicseen.html
Time does truly fly as I initially posted that back in June 2012.
I have been slowing buying the various components. It has been a journey with a doubt.
I got the iNuke last year some time while on a trip to the UK.
I got the wood cut and it's been lying there.
I eventually got business trips to the US in Feb and March of this year.
This is where things got side tracked a little. I initially wanted the 15" Dayton Titanic MK3. I then wondered about the TC Sounds LMS-R.
As luck would have it both were sold out and would not be available for a while off Parts Express. Luckily I came across the data-bass site and read a favourable review
of the Dayton 18''. I had already invested in the plywood and could not avoid not using it. I modelled the dual 18'' and with significant stuffing I could get a reasonable result, so I took the plunge and ordered two.
FYI: If travelling to USA - fly Virgin Atlantic as even in economy and although you go via UK - you are allowed 2x 23kg bags plus you can pay for an additional 10x 23kg bags.
Both sub boxes where opened by US customs and inspected but they arrived here without any issues - plugged them up last week in free air and they bounce (literally).
The subs are double boxed but I opened them and added additional padding - the check-in weight was around 21kg each.
The first step was doing a fan mod on the iNuke6000. The fans were far to noisy for in room use. I really wanted to avoid 80/90mm fans as there is just too much air turbulence for complete silence while having decent airflow / static pressure. I decided to use 140mm and 120mm and even bought some alu heat-sinks (which I did not end up using).
The fans headers are glued down and so I decided to leave them and unsolder the cabling from the fan itself. I then soldered new fan headers and connected up some
fans I had to test noise and air flow. I then build a prototype cover using Masonite to work out ideal fan positioning. I then build a second Masonite unit with more accurate
holes. I build a clear perspex model of that and it's looks and works great. I initially tried the AeroCool/Scythe combo and although the airflow was fantastic I could still hear
a very fine hiss from 3meters in a totally silent room. You would never hear it during all but the most silent passages. Still once I tried the Noctua combo there was only one option.
The airflow is less but I can't not hear it at all from about 1.5meters. I tested both combinations with rubber fan holders, with and without dust filters. In case anyone is wondering here are the tech specs for the fans.

Haven't decided on a name for the project, but need something that will fit... - Titan, Kratos, Kraken, Big Bertha
