Stu, have you considered a fully active approach to your speakers? I realise that the active approach is anathema to many but I do see certain benefits and it is indeed the path I am currently following.

The frequency response is a must measurement for speaker builders, to augment your ears I agree with Daniel on this one. Whilst one's ears are are the final arbiter, it's helpful to know why something is sounding as it is. For example, honky vocals might point to peaks in the 800-1500hz region. A q...

Soundstage implications are interesting. I have to say that my DIY OB speakers provide an extraordinarily big 3D soundstage that's high wide and deep - distinctly better than my semi-omnis. However, they need room to breathe with a meter or more behind them. Therefore, this would mean more rather th...

Whenever I was looking at new speakers I included B&W in the audition. TBH they never impressed and came across as very 'meh'. I've never warmed to them at shows either.

Slade: Play It Loud. A much underrated album IMO. Their second studio album and an indicator of the direction they could have gone in.

Very nice melodic Prog-rock from Norway. Similar to Riverside and a bit Camel-ish.

Mmm, another one to check out! Anything like Nightwish?

One area I personally think could usefully warrant a push is DIY. There is of course diyaudio.com, but things can be hard to find there. For example, I'm exploring open baffle speakers and also Distributed Mode Loudspeakers. These 'alternative' technologies would seem to fit in well with the HFS thi...

I'm going to be a bit contrarian and say 'neither'. My open baffle experiments have worked well, to the point that I'm unlikely to go back to a box speaker of any description. I will add that I'm about to build a Distributed Mode Loudspeaker (DML) type section for the mid & top section of my OBs...

Simon how long has it taken you to gain the experience to do what you're doing ? Hard to put a precise time on it. It's really been lots of bits of reading on and off over about five years including my first exposure to class D chip amps, but about two weeks of execution once it made sense in my he...

The project continues! The latest step is to replace the Monacor FR driver that was doing tweeter duties with a pair of SEAS 27TDFC fabric dome tweeters that I already had. Needless to say, they are a distinct improvement with a sweeter top end. Efficiency @ 90db matches the bass/mid driver that is ...
