    I found these resources for designing sub enclosures. They've got good detail without getting too technical, definitely worth reading if you're thinking of building your own box.

    Anyone able to calibrate a Behringer ECM8000 Measurement Microphone?

    Hi everyone, Is there anyone out there that's able to calibrate a cheapie Behringer ECM8000 microphone and create a calibration file for it? I don't really want to fork out R3k plus for a microphone that comes with a calibration file as it will be used very seldomly. I'm keen to learn how to do...

    A comparison, Polk Audio RTi10 vs Bentley Acoustics FS-150

    Good evening everyone, This is a long read, so; TLDR; go to the end of the post to see the differences in point form. Otherwise, sit back, grab a cup of coffee, put on your favourite tunes and (hopefully) enjoy the read. I won?t really call this a review, I don?t have Agaton Sax 's ability...

    Heath Robinson "12V Trigger"

    Hmm, to be honest, I'm actually posting this in reverse. My sourcing of pre-outs project should've been first, because if it wasn't for getting that right, I wouldn't have done this little project. The pre-out project was a proof of concept that actually worked very well. I'll post it once I've...

    Stephen Mantz: South African born audio legend (Part 1)

    Sorry, I have to split this in two. After the huge improvement my Rotel RB-985 displayed when Nilam serviced it, I decided that the same should be done to my Harman Kardon Citation 7.1 amp. The HK is about the same age as the Rotel, from the mid to late nineties. I downloaded the service...

    If you have an older amp, I recommend getting it serviced.

    I recently bought a set of Bentley FS-150s and a Rotel RB-985 five channel power amp to drive them as well as the centre and surround speakers. It's a brilliant combo, but having gotten over the initial euphoria, I was able to sit down and listen more critically to the system. There was...

    So I bought a pair of Bentley FS-150's

    Polk RTi A7 vs Bentley FS-150

    Yes, yes, I know, I know, yet ANOTHER speaker A vs speaker B question, ?Go listen to the #$%^!@ speakers and make up your own mind!? I fully agree with that statement, but please hear me out.  I want to upgrade the Mission MV-8e fronts that I currently have with something bigger and bolder, they...

    Birthday sub build

    Hi Everyone, Yet another sub build, with a nice twist at the end! Some time ago I gave my nephew ( El Sid 's son ) a 5.1 set of TLS ?Reference? (yup, note the quotes) speakers as they weren?t being used any more. It came with a 10? sub in a small enclosure that made some noise, but certainly...

    Targa Viper 15" drivers appear to be back in stock

    Was online window shopping and came across this on the Autostyle website. I haven't phoned them to confirm as it was too late, the drivers haven't been available for about 2 years now. Really good price too. https://www.autostyle.co.za/product/targa-15-7000w-dvc-subwoofer/

    Undercoat that's easy to sand smooth

    I'm currently building a 12" sub for my nephew (I'll post it once I've finished it) and I'm looking for an undercoat that sands easily to a nice smooth finish. On my previous builds I didn't really worry too much about the final finish as they were mine, but this one I'd like to finish it off...

    12V trigger operation - Advice please

    Hi All, Unfortunately my Onkyo NR575E doesn't have a 12V trigger port, but it does have a USB port. Murray has offered to help design and build an adapter for the HP DPS-1200FB power supply so that the AVR can trigger it when the AVR is switched on and off. I want to build an adapter similar to...

    Polk DSW Pro 600 subwoofer- scavenge for sealed build or flog?

    Mods, apologies if this is in the wrong section, please move if it is. I have a Polk DSW Pro 600 subwoofer given to me by a client that no longer works. The plate amp is trashed, I gave it to Nilam to have a look at it and he confirmed that it wasn't worthwhile trying to fix it. The driver and...

    Mission Mv-8E speaker upgrade

    Hi Everyone, I did this project about a year ago, unfortunately work kept me busy in the evenings and didn?t get round to posting it. I discovered the photos whilst deleting tons of crap off my phone that people have been sending during lockdown. It seems some of the photos are missing so I?ll...

    A couple of questions for the experts, AV cabinet build

    Hi everyone, So, we have decided to move the home theatre and create an entertainment area upstairs. The wall space is quite a bit smaller upstairs and so a custom AV cabinet will have to be made. In order to accommodate reasonable sized speakers and subs, the speakers will have to be built in...

    MAME Arcade Game cabinet audio upgrade

    Hi Everyone, This is a bit different from the usual audio DIY stuff, I don?t think many people have done this before. I bought a couple of arcade machines a few years ago from someone who had closed their gaming business. This was before the current ?Retro? craze hit the scene, where vintage...
