Hi All, I'm about to do a basement conversion and have quite a few questions if people wouldn't mind helping. I'll also be posting designs etc. and may as well start a build thread as a thank you for anyone reading After making quite a few calls round to different companies that i believe were potentially equal price performance for M and K inwall 150 series speakers, i had quite a lacklustre amount of feedback and support from most companies when my budget probably wasn't up to their usual clientele or my noob questions kept piling in. Not however from Rob Sinden at Gecko Home Cinema, so a big thank you to Rob! who has been very patient with me and was very hospitable with his time hosting me for a demo day and answering all my design questions. So i'm glad to say i will be heading for the below spec: 7.2.2 Atmos: Marantz Receiver Lyngdorf TDAi2170 as intelligent slave amp 3 x MK IW150Mk2 LCR 6 x MK IW950 side speakers 2x x10 subs 65inch LG OLED (prob c8 once release) I have been learning how to use Google Sketchup to help support the design stages and hopefully you guys can help answer any queries or point out any errors i am making in advance.
