I'm in the process of upgrading to a 9.2 system with Ascend Sierra Towers and possibly Rythmik or SVS subs. I'm about 50/50 between music and HT, but an amazing musical soundstage is whats really important for me in this system.

The general consensus seems to be that sealed subs are better for music and ported are better for HT. What if I were to get one of each? Since the .2 is just an even Y-split the extra boom from ported would give me what I want during movies and the sealed sub would give me the control and depth for music. (I understand I may have to power off the ported sub during music time).

Is this just a dumb idea?

Should the Sierra Towers give me all the bass I need for music allowing me to focus my subs strictly on HT?

Ported subs can also be very musical. Your choice between the two should depend on your room size and budget IMO.

How big of an area do you have and what is your budget?

As for mixing them, it's not recommended.

The room is 18x20, carpeted with low ceilings (basement). Budget for subs is 3k.

I prefer sealed subs as well. They aren't as popular because they don't go as low and don't play as loud for the same driver. It is hard to imagine why people are worried about bass extension for movie LFE. All of it seems to be above 30 hz, most of it way above. I solved the issue by building a 15" sealed sub. It goes into the mid 20's in my room and moves enough air to shake the room enough to cause you to catch your breath. My room is the same size as yours. More than enough for me. I'm not interested in breaking windows. It sounds better than any ported sub I've heard but, of course, I haven't heard them all.

Personally I don't see a huge problem with having a sealed and ported in the same room as long as they are phased and level matched for movie LFE. For music it might not be ideal because the ported sub would react differently to changes in level than the sealed sub. i.e. volume levels might be inconsistent. You could simply turn one off for music listening.

You have a healthy budget. You might even be able to find a pair of sealed 15's within the budget. If you spend it on a pair of ported 15's you are also likely to get pretty good sound because the better ported models do sound better than the budget models.

With cabin gain, sealed, in an enclosed space, will go lower. Large open spaces are best served by ported subs and smaller, enclosed spaces are better served by sealed subwoofer systems.

It's economical to go ported as a ported is better at pressurizing a room but if one wants depth, sealed is the way to go but it takes more sealed subwoofage which, depending on the venue, makes sealed more expensive; uneconomical.

I prefer sealed for depth of extension.

A flawed concensus that would be. Accurate response is accurate response, no matter what the cab topology. The only difference between the needs of HT versus a music only system is that HT goes lower, by as much as an octave, two if you're really into a no holds barred system.

Not dumb, but not worthwhile either. You'd only want to consider using different subs if they're in different systems in different rooms.

Working with basshead81's recommendation above, with a $3k budget, one would also be able to entertain the purchase of a pair of PSA, XS30's (sealed) or a pair of PSA, XV30/XV30f's which are ported.

Thats why I love and hate these forums....every new piece of information or recommendation leads to another month of research. I'll definitely look into PSA though....

If I had a $3000 budget I would try out the 30 day in home trial.

The F25 has 2 15" drivers in one enclosure. The XS30 is similar other than its a dual opposed config. What dont you know about that?

You said "dual" F25's...as in 2 of them. 4 subs.

Obviously I misunderstood you, but initially I thought you were implying getting 2 dual stack boxes....or 4 subs. A bit of overkill IMO.

Agreed. I doubt I would consider it at half the price. Still placing it more than the XS30 and about the same price as the F25.

With that space and budget I would get two svs pb12-plus's or maybe two rythmik fv15hp's.

Good luck getting two sealed subs to work well in that basement. I had four 18's in my basement to get the performance I was looking for.

Your right I said dual F25's which means 2 subs. It does not matter how many drivers are in a enclosure, it is still considered as one. There is no such thing as overkill with bass smile.gif

His room is only 2500-2600^3...dual F25's would tea bag dual PB12+'s in that room. The F25 is only down 1db to the FV15HP @ 20hz and would probably have 4db more output above 40hz. I am betting single digit extension will be achieved with substanial output.

Right but it depends on how well sealed off the basement is. They can be hard to seal off.

I'd look here first:

http://www.data-bass.com/systems

If its not here, its probably not a first-tier contender for most people who are into subs.

First time I have heard of one sub tea bagging another sub! tongue.gif

no way. :-)

for example, genelec and meyer sound employ ported subs in their top of the line music systems and they are two of the most sophisticated players in the studio/professional subwoofer business.

Listen. It's All Good.

I'm sure the EP800 is a beast.
The spec's, awards and reviews seem to suggest it would be worth considering.
Myself, I've got a couple miss matched subs which work well together.

The specs are from Axiom which isn't exactly reliable and the rewards mean nothing. If it is a beast they should send it to Josh Ricci at Data-Bass for testing, but Axiom doesn't trust unbiased reviewers they want shiny marketing articles and fancy awards above real actual substance. After a disastrous outcome with the EP600 from Ilkka, Axiom doesn't really allow real testing of their speakers.

At $2500 your at a pretty stiff price range for competition. And a 800watt dual 12" seal subwoofer isn't exactly earth shattering performance. With the Rythmik F25 at $1000 less that is a no brainer. As well as the Power Sound XS30 which is another great sealed subwoofer. Hell even the Power Sound Triax triple 15" 4000watt subwoofer is only a few hundred more than the Axiom.
