Hi all, I've been clearing out the garage a bit, and have realised I have way more amplifiers than I actually need. Here are the ones I'd like to move along: Behringer iNukes: - 2x NU6000DSP - £300 - 1x NU6000 - £250 - 1x NU4-6000 - £300 - 1x Cloud VTX1200 - £150 - 1x Cloud CV1000. Rough condition, ...

A final point on the Owston front, if I may: You're unlikely to hear these speakers at their best there. When I took the 18" subs to Owston last time, I got the subs + speakers measuring flat with the mic near-ish the cones. Mostly just checking the integration betwee the two. When I pulled the...

Had another day at Colin's last weekend, and we set about tweaking these speakers further, to see what could be done about the notch in the response at 100Hz. After trying a few measurement positioned, we realised that the problem was in the vertical plane: moving the mic a few feet upwards filled i...

BMS has been doing similar for a while: https://www.bmsspeakers.com/index.php-1 ... ms_15cn890
But not with an 18" cone!

Neat way of getting full-range out of one box, and I can imagine an 18" stage monitor being popular with drummers.

Just a quick note that FIR-based DSP can manipulate frequency and phase responses independently of each other.

ie, you could dial in a boost/cut without any phase shift, or dial in phase shift without changing the frequency response.

Steve,

If you're thinking about 2.5" drivers, the SB65 is worth a go. Nice little driver with a copper sleeve on the polepiece for demodulation.

If we get together to play with those new horns, I can bring a BMS along to try if you like.


I must admit that I haven't got around to doing much with them just yet. There's thought towards a Synergy horn build for PA use, but it's very much in the contemplative stage at the mo.

IIRC, the EQ ended up as follows: 2nd order lowpass 38Hz notch 100Hz boost With varying filters required to achieve the right shape in each place. The 38Hz notch, IMO, was very very necessary. If you play Hey Now by London Grammar, the bass notes should be even in volume, with the very bottom note (...

Just to add to that. When we went to the original mk1 filter with -3db at 265Hz, when increasing the bass level to the point it sounded right, it was stamping on the clarity of the mid range. So that's when we noticed it was 265Hz not 200Hz, dialing it back to 200Hz allowed the bass level to be inc...

Thanks for your thoughts Chris. i was wondering, reading between the lines on the other thread, if your problem with 'realistic sound' was loudness. My concept of 'realistic sound' does not require it to be loud, certainly not as loud as modern gigs. Also, all lot of what I listen to was never play...

Nick, I'm not even sure that an orchestra can be recorded with accuracy. Mic positions are typically 10+ feet in the air, often positioned just behind the conductor - that doesn't seem like a realistic listening position, but it does seem to be the place where microphones deliver the most pleasing r...

A bit of a philosophical discussion, I suppose, on the subject of "HiFi", realism in audio, etc. I gave up on the concept of HiFi a while ago, for a few reasons: - The first is technical. It's my opinion that there are simply too many filters between us and the musicians to get a truly acc...

It's about recreating real life <snip> Apologies to anyone else that i just rubbed up the wrong way, but I just feel really frustrated. Mark, I think it's here that our ideologies are fundamentally different. Here's the crux: I gave up chasing "HiFi" a while ago. In my opinion, it simply ...

Yep. Nick's OBs certainly let more light through.

How would you measure/define transparency in audio?

Chris

Simon, When you say "8x average", do you mean you told REW to do multiple sweeps in the "Measurement" pop-up, or did you run the same sweep eight times (ie, clicked "measure" eight times, did 8x single sweeps) and average those? Assuming the same mic position, I find th...
