"Yuli said" is great evidence dude. I remember when you used to make sense.... If I recall correctly, Yuli also said you get port noise if you go with too large of a port, which has never, ever happened to me, nor anyone I've ever met. But this isn't about Yuli at all. It's about pulling crap out of your ass and calling it fact. This is all theoretical for you because you know absolutely nothing about the Sundown Audio products.

I know Scott didn't mention that he was considering this before, but maybe they'll be able to rework the suspension to allow a little more Xmax; that seems to be the limiting factor, but I think it's tough to get a good, long throw suspension on a 6.5" driver, especially without going to a really custom frame. Still, the first iteration was so good that you can't not be excited for the next.

More material in the mids, so you'd get more use out of it there.

A nice slow day at work feels good on a Friday.

I blow a damned gasket every time I see someone post on Canadian Car Audio about the Sundown products. Those Alberta and BC guys are just ridiculous and illogical. On the topic of the two amps that are being compared, there really is no comparison to be made. I do like Kicker and some of their reps are fantastic guys (Tracy Focht comes to mind), but let's break things down a bit. SAZ-1500D is less expensive. SAZ-1500D has a longer warranty. SAZ-1500D can handle much lower loads (ZX1500.1 "can" go below 2 ohms but only in very ideal situations, whereas SAZ-1500D can get under 1 ohm pretty easily) SAZ-1500D can easily be repaired and replaced. SAZ-1500D has better, more easily accessed support. It seems like an easy choice to me.

Coke cookies, maybe? Any 3000d's there Jacob?

I'm sorry, I'm a little lost with some of the acronyms flying around I feel a little ADD^^ (I had to go there) http://en.wikipedia.org/wiki/SPARS_Code

Perhaps this should be prefaced by saying these are all opinions. For whatever reason, this always ends up being very hotly debated topic. I would say in general, you will here this most often: Vinyl DVD-A or SACD CD Cassette 8 Track I can't put reel to reel in there because I've never heard it (and don't know anyone who has) and digitally stored media is too all encompassing (what is the audio codec? what is the bitrate? is it transcoded? etc.) My personal preference, however, will always be vinyl or FLAC. Vinyl can be great if you're playing a well mastered recording for the first time. After 10-15 times, the experience might not be quite as enjoyable. With FLAC, I am guaranteed a "lossless" recording every single time. FLAC is easy to transport and widely available on oink.me.uk. The argument always seems to arise in the concept of converting from one format to another. Jim made a great point when he said reel to reel, empirically speaking that is. However, many companies are using all digital recording (which is becoming increasingly popular) and this eliminates any losses from analog to digital conversion. As far as raw capabilities are concerned, DVD-A has to be near the top based simply on storage capabilities. Of course, we can always make an argument for audibility: can you really hear the difference between a v0 mp3 and vinyl? A lot of people have difficulty proving that they can. To me, regardless of the medium, it comes down to who mastered that particular release. I know on a few occasions I have preferred a vinyl LP to the CD version or vice versa, only to find out that any differences could easily be attributed to the difference in mastering techniques.

Pretty much. Is there a difference? No doubt. Is it audible? Extremely unlikely. Will it cause damage? Virtually impossible. Another way to think of this: if you have two speakers in a ported enclosure, the one closer to the port moves less (servo effect). Naturally, the one moving less will have a less exercised suspension. Does it matter? Nope...

Exactly. Like virtually everything, it's a negative if it detracts from the intended design and a positive if it adds to the intended design.

It depends on the application. In a lot of standard high power subs, you'll find a pole vent to help dissipate heat. However, a pole vent can be a bad thing. In terms of cooling, the idea is to move as much air past the coil as possible. A pole vent usually means that the vent is one of the exit points for the air that cools the coil. If we plug this pole vent and change some motor internals (like adding venting to the pole piece), you may find that there are other ways to route the air and cool the coil more efficiently. This is something that is done on the BTL from Fi Car Audio.

Adding more to the stack only works if the steel is not already saturated. At that point, you can achieve higher BL through integration of B. Of course, adding more B is totally useless if you haven't got the L to integrate the flux. More magnets does not translate to a larger gap, a taller top plate does. But! A taller stack can be used to gain more clearance in the rearward direction; yes, you could just machine a taller top plate, but it proves more challenging to saturate and magnetic material is much less expensive than the purchase of raw steel and the machining required after the fact. All things considered, a thin and wide magnetic structure is preferable, but this really limits your rearward clearance.

Bingo. High Qes with no better than average Mms means you've got a driver that isn't especially efficient; average at best.

Well, higher and lower BL (more specifically, BL^2/Re) most definitely relates to damping, as it manifests itself in Qes. Whether higher or lower is required is dependent on the intended application. The fundamental issue at hand is not an argument of whether high mass sounds sloppy or high inductance sounds sloppy, but rather that a poorly engineered speaker will sound like a poorly engineered speaker. There is nothing inherently better or worse about any speaker size or even any speaker material if the design is well engineered to compensate.

Very happy bithday Shawn.

Welcome and enjoy the show.

I always used the "View New Posts" button instead of this, but this is very nice as well. Have you given any thought to moving this to a side bar?

For a subwoofer, I think the perceived accuracy of the driver has a lot more to do with the damping characteristics of the speaker and the enclosure it is coupled to. I agree that inductance has an effect, but not a particularly noticeable one throughout most of the average subwoofer's bandwidth. If it's below the inductive rolloff corner frequency, you won't see much effect.

I am a fan of D2's right now because they allow me to maximize my power in the vehicle and the house (for single sub setups, of course).

Happy Birthday Aaron.

Just for future reference, the SSA Shop forum is here: http://www.soundsolutionsaudio.com/forum/i...hp?showforum=56 On the index page, it's the second group of forums. Sorry I can't move it or answer, but Aaron and Mark will certainly take care of you.

Wow, well priced.

Is that a spray-on liner? It's a nice understated box treatment, that's for sure.

Forgot how much I liked this song so I just had to post it. Queen - Radio Gaga With the right stereo, the bass that serves as the driving bottom octave harmony sounds absolutely great. One of the few times where I've thought "hey, that bass sounds good!"
