UNDER CONSTRUCTION!

System Description

I now have 8 channel DRC working using Convolver Plugin, DRC and Rec Imp.

A detailed write up is here:

As you can see it's a constant work in process. I still need to veneer the main speakers, and build grills to keep my 2 year old daughter Kate (now 6 and still no veneer, and now she has a sister Hannah) out of the drivers...nah bugger the grills.

The system's vital statistics are as follows:

• 7.1 channel HT system with 11 speakers.
  • 3 front L/C/R channels

• Fully active 2 ways + stereo Subs
  • Focal TC-120TDX2 Tweeters
  • Focal 7NV4411 7" Midbasses x 2 (MTM arrangement)
    • Drivers from Aranmar Acoustics

• Analog Active Crossover
  • DIY 3 Channel, 3 way.
  • 24dB/Octave Linkwitz Riley Crossovers at 110hz and 2400hz.
  • Using PCBs from Rod Elliot

• Subwoofer
  • IB sub using 4 x 15" long throw woofers, also bought from Acoustic Concepts. Manifolds mounted at ceiling, venting into the roof cavity.
  • More info about IB subs here at the Cult of the Infinitely Baffled
