$430 for a SA12 ?

 

Crutchfield is only good for specs reference, their pricing always atrocious. They charge MAP pricing and then some.

 

That's unfortunately probably going to be the new baseline for that class of 12" now. That's what the base model SQL 12 is priced at as well.

 

probably. i bought a 12" Xv3 for $240. the Xv4 is $420

 

Why the limited lineup? Where is the salt amps?

 

I don’t get why is this huge. At all.

Was there not other purchase channels for Sunddown products before? Is Sundown in any way an exceptional brand?

Or are you just spamming the forum?

 

Sundown is exceptional, their SD10's are the very smoothest subwoofers I've ever owned, bar none, and I've been playing this game for nearly 40 years now. I replaced my W6 with an SD10.v3, and the difference was MASSIVE. So much more linear. So much more controlled. So much smoother, and dug way deeper. And the only thing I changed was going from the W6 at 3 ohms to the Sundown at 8. I didn't touch the amp, EQ, or anything else.

And Crutchfield's service after the sale is also the best of the best. Are their prices slightly higher? Sometimes yes, sometimes no. But it's the superior service that makes it worth it. And yet again, I've been a customer of theirs for almost 40 years now.

So no, I'm not spamming. This is really big news. At least as far as I'm concerned it is.

 

Why does no one in the sq community use sundown subs? At least no ones mentioning them.

 

Because they are designed with spl as their main focus. They don’t have the most precise transient reproduction of audio. Their frequency range can be limited on the top end making them hard to mesh without a front sub. And to be honest it’s also just a stigma since they are spl, but no doubt they have some of the best low frequency out there. IMO, they are great with some tuning, I’ve heard it sound great in a sq system, but you probably want a front sub that’s sq focused. Something quick because the subdowns can be sluggish.

I think it’s exciting. Crutchfield is a great website

 

The only issue with the SD underhung subs is they have poor inductance. They still use an 8 layer coil without any shorting rings in the gap, so Le(x) is bad. Normally in a sq sub, you want your inductance to be a low ratio to your Re.. .5 or less. The Le on those are 1.2-1.5x the Re, which is worse than many SPL subs.

 

My limited understanding of inductance is that it’s only a problem in subs if you intend to play them high? Can you elaborate a bit of the problems of a high inductance subwoofer?

 

we have a shop that is a sundown dealer here. The installer has told me several times that the SD subs sound very good. Like surprising good. He was also tell you that 90% of what the sell is the SA series.

 

Inductance over stroke, or Le(x), is a significant contributor to THD. Inductance overall affects the time domain performance, which includes IMD and what most people interpret as transient behavior.

 

So a real-word example may be that it’s difficult to integrate sub and midbass (or front sub) with a high inductance sub?

Not explicitly by itself, it is dependent on the whole install. More along the lines of say a sub is playing a 30hz tone, and gets whacked with some 60hz impulse tones at the same time. The inductance will affect how clearly those transitions will sound.

On my SML8, the Le is 4.4, the Re is 6.9. It's placed in the passenger footwell, and it blends perfectly with my Legend 1800.3's.

Yes, that is a good resting inductance, but since that line does not use shorting rings it will have poor inherent Le(x) just by design. I'm not trying to say that inductance will make a sub sound bad.. there are plenty of highly regarded subwoofers that people love that have awful Le(x), but just pointing out some of the variables that set a high end SQ sub over the rest.

 

Can get the whole line at singhelectronics.ca at good prices ship to USA also though may want own broker / forwarding if they use UPS....

 

MAP pricing checks, not surprised this marriage happened.
