Re: Fane 12-250TC Retro Speaker.

To control mechanical cone breakup would need a tiny mic mounted on the cone which measures the velocity/acceleration and sends back data for controlling the amp. I have such a thing in my active Velodyne sub. Not quite. Feedback-controlled subwoofers rely on the cone acting as a piston. ie, what's...

Re: Fane 12-250TC Retro Speaker.

Steve, I like your approach here. Keeps the signal chain nice and simple, which is something I've struggled with when going with active EQ/crossovers etc. IIRC, there was something that went round diyAudio for speakers with whizzers that was meant to smooth things out quite well. It was before measu...

Re: Room Treatment (Split from Owston thread)

Fair enough. Take time to relax - I'm happy whenever.

If anything, the later the meet, the more likely it is that my speakers are finished...

I don't know enough about drive units to say, but 0.1% above 100hz, rising to 1% below seems a long way from low distortion to me.
Someone has done the work - http://zaphaudio.com/6.5test/
There's a link to click on that shows distortion levels etc.

Re: Room Treatment (Split from Owston thread)

Just wondering if we're anywhere closer to setting a date for a gathering. FWIW, I took delivery of some acoustic panels yesterday (found them on eBay - small manufacturing defects meant they were heavily discounted) and took a before/after measurement. The frequency response didn't change much, but...

Re: Nothing In Particular

Finally got the 8" speakers up and running. After a while playing with the HF level, it's sounding pretty good.

Pictures coming soon.

Re: North West Audio Show - Cranage Hall

Fair point, but if any HiFi buffs do need a PA system, it'd be nice if they called me first.
I'd like to attend, and will see how the calendar looks.

Re: ariels

What about building something to surpass them? IIRC, Ariels are an older design - perhaps something with modern drivers would be even better..? FWIW, the speakers I'm working on at the moment do well for bass precision - 8" aluminium cones in sealed boxes, crossed to a 1" compression driver at aroun...

Re: North West Audio Show - Cranage Hall

Thanks for the info, Nick. Bit rich for me - I was thinking of setting up the PA system as a HiFi with a small "for rent" sign, but that sort of money would be more risk than I'd like.

Re: North West Audio Show - Cranage Hall

Looks like an interesting day out. Will see what I'm up to that weekend.

Anyone got a ballpark price for a room, and know whether any furniture is provided? - Might be interesting to exhibit.

Re: Fane 12-250TC Retro Speaker.

It varies a bit. Bands that tour with all their own gear usually have in-ear monitors. My stages are usually full of wedges - if they're hiring me, they don't have their own gear. The stage monitors I use the most are 8" coaxials - at close range, a couple of hundred watts into one of those is plent...

Re: Nothing In Particular

Nice pile of kit to play with. I think your plan is sensible. 2 batteries in series, 3x groups in parallel would give the 24v the controller is intended to work with. However, I don't know if the 3x groups will need any special treatment to avoid them interacting. If one battery fails, it might end ...

Re: Nothing In Particular

I do like this amplifier. There's a button on the remote for each input, so there's no cycling through and trying to remember which one you're on. When you switch the input, you get a couple of little clicks as relays move around. It's all very satisfying. Starting to wonder if I really need the big...

It looks like I can't embed the pictures from Google Drive, but here's a link to the photos:

The rosewood cabinets will be heading to Phil shortly, but the FE126 drivers are still available.

Re: Nothing In Particular

A Cambridge Audio CXA80 fit the bill nicely. Found one on eBay, mint, for sensible money, and it arrived today. Chris I read a review of the CXA80 and it seems impressive. :) Well, the transformer is a tiddler compared to the ones in the Crown amp, but it seems to do the job. I've got Barclay James...
