Athena AS-P400 vs AS-P4000

I have read through all the threads I can find on these subs and from what I can tell people feel the AS-P400 was built better and sounds a bit better. But with the 4000 was the port noise reduced some? I have a 400 that has quite a bit of port noise when you get under 30hz.

So you don't notice any difference it port noise? Doesn't the 4000 have 2 rear ports and therefore more port area? If so, my thoughts are this will reduce the port noise that I am hearing below 30hz on the 400 as compared to the 4000.

It was discontinued but there are a few out there still. I already have the 400 and since they were so cheap I was going to pick up another and go with the two subwoofer approach. So here are my options:

Get one more 400 for about $250

Get two 4000's since I can find them a bit cheaper, total about $370. I would do this if the 4000's have less port noise. But I like my 400 and a lot of people say the 400 is better.

Or if I'm going to buy 2 subs, why not get two 6000's. That pushes me over $500 and more than I was going to spend. Will the 6000 sound as good as my 400, just louder and lower? I listen to a lot of concert DVDs and music and the 400 is very musical. Will this be the case if I move up to the 6000?

That's my dilema.....

Not sure, could it just be they are out at the moment? You can find them everywhere else.

That is exactly what sparked this whole deal for me, when I saw a bunch had just sold on ebay so cheap. But there haven't been any since and I'm patiently waiting.

Over in the Athena Owners Thread I found this....

"As the sales manager of an independent retailer, who has sold Athena since the original SCT series, I can tell you that Athena is just fine. API has kept this line-up pretty small only releasing the updated AS-x.2 series (change of woofer and tweeter trim color to silver) and the WS series in the past year or so. This year we will see some minor changes as well.

The AS-B2.2, the F1.2, and the AS-P6000 are going away (in fact, my rep told me this past week that the P6000 is already sold out). The WS series is changing color from silver to black aluminum. The in-wall/ceiling line may not last the year unless API sees a major purchasing commitment from a box box retailer. The Micra-6 will only be offered as a 5.1 HTiB which explains the individual packs being sold out through Target.

Athena plans to introduce at least a couple new models probably serving as replacements for the B2.2 and F1.2. All I have been told is that there will be a new bookshelf model this year accompanied by a dual 6.5" tower. Too soon to tell if they will be inserted into the Audition series or if they will be the foundation of a new line-up.

So, once all the changes are done, API is still planning on keeping the Athena brand a small tightly-focused line, and I'm sure they'll be around for some time to come (with or without BB). At least I hope they're not going anywhere because it has been a great line to sell over the past 6 years."

No mention of the 400 or 4000 but eliminating the 6000. Maybe that is a sign they will be coming out with a new 10" design.
