Re: Something stirs in the Undergrowth

True, you need to use ground-plane or similar measurements for the LF & merge into the gated for the rest of the range; on the other hand, I thought (I admit I've only skimmed the thread so obviously I am in error) that the current issue was more with the transition from the midrange to the HF, for ...

Re: Something stirs in the Undergrowth

Or just gate the damn thing to remove the reflections. Job done. Is it as good as an anechoic chamber? No. Is it fine for system design purposes? Yes.

That's a heck of a transformation from that dodgy bit of bent aluminium. Looks great now, but I know how much work you've had to put into making them that way...

Re: Edingdale GT, the ultimate Edingdale? Probably

Lovely build Colin, if my Sr's are anything to go by I imagine they sound really good! Find myself wondering how the new tweeters into my SRs with any needed XO mods would sound? Probably a step back from what you currently have. Thing is, a multiway loudspeaker is about more than achieving a given...

Re: Edingdale GT, the ultimate Edingdale? Probably

...internal XOs usually my favourite option from the convenience side. Granted, not necessarily for the poor soul building them. ;) Humour aside, bad luck Colin, sorry to hear the cases aren't up to scratch.

Still frighteningly good speakers though, even if I say it as shouldn't.

Re: Edingdale GT, the ultimate Edingdale? Probably

Agreed Nick, but as far as crossovers are concerned (I can't comment on anything else) the transfer functions are my first stage for assessement. If they are affected, it's a problem, simple-as. If they aren't, it may, or may not be a problem, so I go down the check-list as appropriate. Ideal would ...

Re: Edingdale GT, the ultimate Edingdale? Probably

I suspect it will be OK; the magnetic fields from the crossover inductors shouldn’t be particularly large as these things go and I gather the box has reasonable internal space, so with a bit of care over component placement I doubt the transfer functions will be affected. If so, then it gets adjuste...

Re: Monacor SP-310CX Coaxial Driver MLTL's

Snowed under with work for the foreseeable so no time for audio as such. Sorry. However, briefly: The K+T design is tuned to about 45Hz (impedance minimum between the twin vented box peaks). However, F6 (-6dB point) as can be seen in the FR, is around 80Hz, and about -18dB at Fb; granted these are [...

Re: Something stirs in the Undergrowth

There's no direct drop-in equivalents for the P13, although I imagine Audio Technology could produce a semi-custom unit that would be close, albeit with more advanced cone, motor etc. And a serious price tag. ;) The closest standard units I can think of would be the Seas U16 and Scan's snappily name...

Re: Something stirs in the Undergrowth

I'd be a bit wary on that front to be honest. I like the FX120 very much; I've said for the thick end of 15 years it's about the best 4 1/2in driver Fostex have made, in some ways outstripping the F120a with the AlNiCo magnet & slightly different surround. However, it's also a different animal to th...

Re: Something stirs in the Undergrowth

Not had a whole lot of sleep lately & taking some time out of work for a few minutes. I like the Ariels within the context of what they are; they're capable of extremely good (exceptional) results, but they're not a jack-of-all-trades design; they're tightly optimised into a particular set of goals....

Re: Speaker Motors

There are a few examples of that; Wilson have / have had a few designs with dissimilar sized LF units sharing the same cabinet volume. As far as loading goes you can create a set of compound T/S values for low frequency modelling purposes; Thorsten did that a few years back. Works OK so long as you ...

Re: Speaker help required...

Unfortunately, driver design in particularly the past 15 years has moved away from the type of units used in the TDL, so you'll struggle to find current equivalents. About the closest general production unit I can think of to that model (note I am not saying it is spectacularly close, though it's in...
