Re: We who are about to die salute you

This biwire Havana is 4 x 4mm2. That's one of the reasons it's such a hefty lead. It's the standard Havana [roughly 2 x 2.5mm2] that's down on copper.

Re: Something Stirs in the Workshop

Nothing as far as I can see, other than difference of approach. I assume that since Seas are using DSP, they simply decided that targeting a given 'natural' system Q wasn't a priority / very important.

Re: We who are about to die salute you

My thoughts exactly. ;)

I've actually been running the Havana RCA and USB leads for a few years -always liked the appearance, and they're a decent spec., especially for the price.

Possibly. But until that inglorious day: If anybody is on the lookout for some 'substantial' speaker wire, you may want to have a look over on av.com at the Havana FX Quad XL biwire.

Re: T/S parameters valid for normal listening levels.

On alignment? Yes, unless you want to do it the old fashioned way on graph paper over an hour or so (I don't either) ;) This is one reason why if you have several sets of parameters, it's usually a good plan to design for whatever set requires the largest Vb so you have some room for manoeuvre. That...

Re: T/S parameters valid for normal listening levels.

Other than in the sense that you have a fairly minor (relatively) shift in the rising / flat BWs, no.

Re: T/S parameters valid for normal listening levels.

I don't think that this is true When you look at the Klippel report I posted, FS changes significantly with excursion from 63.4Hz to 43.0Hz Unless its effect is cancelled out by similar changes in Qts, Rms, Cms, Vas etc. It won't affect my speaker too much since I have a small sealed box, but it co...

Re: T/S parameters valid for normal listening levels.

I would have thought that would be a clear indication how I an defining distortion :-) Right, but it depends on type of distortion as they're in two distinct fields -linear & non-linear. Linear (aka frequency response) is essentially invariant within the designed mechanical operating range, so ...

Re: T/S parameters valid for normal listening levels.

I would have thought that given the driver introduces distortion, that is a result of it being somewhere non linear. Being non linear would make me think there was some level dependent value somewhere in the system. So given that I would be surprised that there would not be some level dependent beh...

Re: T/S parameters valid for normal listening levels.

I've never run across any FR variations -not other than caused by some form of mechanical defect (rubbing coil, tinsel leads etc.), or in a handful of cases excess excursion physically distorting the cone. Those aside that at least should remain consistent; T/S values can be a different matter depen...

Now that definitely can make a good baffle. Or box, if you've got the money / patience / gym-membership. ;)

Re: Quite possibly my last speakers

For whatever it's worth, I find belting a panel with knuckles of very little use in determining its behaviour in actual operating conditions; the energy applied isn't really analogous to how a speaker operates. That's why CRS and aluminium can make excellent enclosures -they ring like the proverbial...
