Well, despite reading comments on here about the benefits of in-room EQ, room measurements, etc. it has taken until now for me to shell out on the Minidsp Umik-1 digital microphone, necessary for making the required measurements. For many months, I had already been using a Minidsp 4x2HD, configured as a crossover for my 4 x EAR 509 II monoblocs, Quad ESL63/ Gradient SW63 woofer system but I wasn't doing any further equalization to correct for any in-room anomalies, as I thought my system sounded very good and that the room was probably good, too. Well, as I'd built up a little extra money in my bank account, I thought I'd take a punt and spend the £109 for the microphone. A quick install of the free REW software on the laptop, a handful of room frequency sweeps , some reading to get some understanding of what REW was doing and the processing of the correction file into my Minidsp 2x4HD and I am pretty gobsmacked. The sweeps highlighted, amongst other things, quite a lift in the 200-300hz region and dips in the sub-110hz region(from memory, anyway). With the correction applied, it's so much better to listen to. Bass is tighter, easier to follow and as a result, detail in the mids and highs is now easier to hear. I'm just simply getting more enjoyment from the music. I didn't spend a great deal of time with the sweeps etc. and fully intend to do some more but putting more time and effort into it. However, for now, I just want to sit and play my music and enjoy the new experience. Once I'm used to the new sound I will find sone time to do further work, including trying out the trial version of Dirac Live. For anyone that has a minidsp unit and hasn't yet got hold of a mic to run some room measurements/correction, I unreservedly recommend that you do so. As has been stated many times by people that have done this, the interaction between the loudspeakers and the room is key and you can obtain a big improvement for a relatively small expenditure by working in this area.
Right this is the start of what might end up to be a very long thread . Apologies in advance to thise that will lose patience but due to my inexperience in trying anything like this there are many stupid questions I will need to ask . Day One Stripping of the Monitor Audio units down to component parts . I have taken the useful hot weather as an excuse to start getting these two units stripped out of the cabinets so that I can look and photograph everything . Sorry for the poor quality of the images these are all phone pictures . I may well get my camera out for later but at the moment my pc is locked in a disc copy so everything is slow . So hopefully in sequence is a picture of the units complete . Then the bass and tweeter units . Then the crossover and then the empty cabinet . Both bass units were twinned to the earth connectors on the crossover then split to an Inductor and resistor each . Resistors were different in both cases with one a 10 Ohm the other a 3.3 Ohm . Think this means they were connected together and can be treated as a single unit but not certain . However as they are identical units I am going to treat them as one for this build. Sorry ran out of space to post more pictures so will need to have a think about what I need to do to post the others . https://bencat57.imgur.com/all/
Just picked up a pair of 104.2 Reference speakers that were close to me on eBay. Usual issues with these speakers ...donuts on the dipole bass drivers perished (but the owner had removed the debris to stop it entering the voice coils) and a tweeter that’s blown. All easy to sort and a bargain at £230 😀😀😀 pics later
