Re: Purifi-based monitor - options
The bottomless notch, in that implementation, is a network which will give a near-dead-short at a particular frequency. That gives maximum electrical damping at that frequency, and (via the woofer inductor forming a potential divider) puts a deep notch in the frequency response. Without the bottomle...

Re: Purifi-based monitor - options
Further thought: the dips in the lower-mid/upper-bass area might be floor and/or ceiling reflections. I ended up adding another driver near the floor to fill in the dips - https://www.audio-talk.co.uk/phpBB3/viewtopic.php?t=8257 Which worked well. The speakers gained a solid upper-bass "slam&qu...

Re: Purifi-based monitor - options
Some measurements here - from approx 1m away : First the full combo, then the Purifi MidBass only. Not quite what I expected actually, although the 3 to 10kHz area is a bit raised. What I'm not seeing is an obvious lump around the 3 to 4kHz area where the Purifi ought to be sticking up in the mix. ...

Re: My Swansong speaker build
I'd written up a reply, and then got logged out before I managed to send it. Here's V2.0. A quick note on the amp at Owston, Nick's OBs, etc: - The amp was a Crown MA5002VZ, and has been well looked after. In its day, it was a very good amplifier. I wasn't particularly surprised, then, that it held ...

Re: PERSPEX QUASAR ver 2.0 prototype build
First order, Mark, and fairly high up IIRC - knocking off a couple of dB at 5kHz-ish. Difficult to define "aggressive", but there are a few things that might be happening. Some of them psychoacoustic, some of them inherent in the drivers. I'm glad they appear to have been well-received. Ch...

Re: Fun at a theatre - 3x Faital 18XL1800
Thanks, gents. I used two of these subs for a village festival over the weekend and they did well with the following settings: - EQ to be flat to 20Hz (requiring lots of EQ and power) - Set a highpass filter to pick the -3dB point, balancing output vs extension. -3dB@33Hz came out about right for th...

Having spent some time with these speakers myself (not in perspex, granted), I'd be interested to read your impressions, Mark.

Re: another cunning plan
Ed, As far as I can tell, "depth" can be attributed to two things while we're listening: Ratios of direct-to-reverb sounds in the recording. Jennifer Warnes's cover of Bird on a Wire is a really good example here. Skip to 2.57. Lead vocal is front and centre, but the echoed lines are to th...

Fun at a theatre - 3x Faital 18XL1800
I posted this on diyAudio, but some of you here might be interested - https://www.diyaudio.com/community/threads/fun-in-a-theatre-3x-faital-18xl1800.386725/ It's nice to be getting back to live events. I've had a few weddings and things like that, but this one really reminded me of why I do it. Chris

Re: What should I hear?
I've tried to present useful information that might allow you to explore new facets to this hobby, and I've been met with "anathema" and "I'm not reading that". Why should I bother?
I'm done. Best of luck to you.

Re: What should I hear?
And your assuming a transparent relationship between what you measure and what you hear. When in reality the relationship is so opaque you may as well ignore measurements and go straight to listening . An unfortunately common misconception. Floyd Toole is someone who actually did the studies on thi...

Re: Much modified Wharfedale Denton
Yep, Faital Pro get a thumbs-up from me. I have the following:
- 10FH520 x2/side in the big main PA speakers
- 10HX230 in the small main speakers
- 18XL1800 - new subwoofers
Even when pushed towards (what should be) the ragged edge, they hold up well.

Re: Monitor Audio - new concept
I was talking specifically about the upper-bass response dips that come from floor/ceiling reflections. Vertically distributed LF sources seem to help.
DSP can't help here, since late(r) arrivals are the source of the cancellations.
