I have 13 W X 20' L X 8' H den with Klipsch RF-82ii's RC62ii RS52's RB61's for 7.0 system and I need to add a sub. I am ordering Denon X4000.

Room is sealed with three doors and no opening space, so I have narrowed it down to these subs.

HSU VTF 3 MK4 $800 shipped

HSU VTF 15H $1023 shipped

PSA VX15 $800 shipped

PSA XS30 $1150 shipped

I am thinking of going with one sub and nearfield placement to feel the impact, please let me know your thoughts. Ported or sealed sub for my place? just looking for tight and powerful bass to hit me.

PS:NO TIME FOR DIY THIS TIME.

I have the VTF-15H in a larger room/s than your posting and its not nearfield I did the sub crawl and placed it where it performed best but its all the sub i will ever need it matches well with my Studio 100v3's ( also ported) which for music which is 50 % of my listening was important plus I have all the slam and deep bass I wanted.

Thank you, I must add this would be 80% movies and 20% music.

In a space as small as yours (2,080 cu. ft. sealed), I definitely recommend a powerful sealed sub. Disclosure: I have personal experience with the XS30's little brother so I'm biased in favor of the brand, but what I'm really recommending is any powerful sealed sub that has a long, extended rolloff, so you can take advantage of room gain and satisfy that obsessive tendency lotsa HT people have to chase the octaves.

PSA XV15 for the loudest and cheapest bang for your buck. I have the same speakers as you do except RB61s. Klipsch are terribly efficient speakers. You need something that can stay abreast with those speakers at loud volumes i.e. 75dB and above.

I must admit I love the value of the XV15 but I am also thinking of XS30 giving me powerful SPL for $300 plus.

The xv15 and xs30 have roughly the same 15-30hz output, but the xs30 has 6db more above that.

I like sealed for the deeper capabilities but if doing a single subwoofer, in my opinion, one would be better served going ported. In my opinion, of your choices, you'd be better served by a fifth/sixth choice, a XS30f or a XV30. I mention the XV30 because you mention the XS30. If considering a XS30, a suggestion would be to give Tom a call at PSA and see if the XS30 or the XV30 would be the best choice as a single subwoofer solution.

Based on your budget, your expectations and your desire to go with a single subwoofer solution, in your price range, another suggestion would be to look at some of the Rythmik offerings.

I am also in the market of buying 2 more subs. I have decide personally to go with ported fv15hps for theese reasons.

• I already have a ported lv12r that will go behind my couch and blend with the fv15hps for better frequency response.

• the shipping on the larger sealed dual woofer units can be quit expensive.

• if I buy subs that have high output and can go under 10 Hz I will probably drive my neihboors even more crazy. I think 14hz is plenty for me anyway

• I'm buying the sub with the thought of home theater 1st and music second, as accurate as the rythmik subs are even the ported subs sound good for music
IMO

With all that being said if money, ease of movement and close neighbors were not a factor then I would say huge dual 15s or larger sealed subs with high output and massive extensions would be the ultimate for both ht and music imo

I know I would be happy with any of the subs esp coming from Sony HITB sub which which still good lol smile.gif. I just need to decide if I should go with value $800 subs or spend some extra for $1000 plus subs.

Spend the extra money or it will cost u more in the long run.

At least decide if u are for sure wanting sealed or ported. That way u can always add another sub and blend it with the old one instead of selling the ported and buying 2 sealed units down the road or vise versa

There are plenty of posters to prove it ported fills a big room easier than sealed and some mfg's offer multiples in the purchase (dual and Quad drive) on sealed after you talk to them state your goal and room size.

+1. Sealed subs rely on cabin gain to fill the lower octave or so. That requires that the longest room dimension be no more than 20 feet, preferably less.

At a room size of around 2,000, I would definitely go sealed myself. Rythmik and PSA have great options in the $1K range.

The room is open to family room and a kitchen. They will prove a major leak to pressurization in the actual listening area. Ported would be the better option in this case.

Really? I didn't know this. Maybe that's why my response drops off a cliff since my room is 23 feet long. Well, that and I'm sure the roll off of my receiver doesn't help.

With a 23 foot long room cabin gain starts at 24Hz, too low to have much effect unless the sub is flat to 24Hz anechoic.

a sealed sub should work well in a sealed 2000^3 room.

The screen wall to rear wall is 20' long, too big for a sealed sub?

That's what I'm saying, I don't think it's too big at all; if my math is good then you could expect room gain from 28Hz down. Maybe Bill can correct me if I'm wrong about that.

With the longest room dimension 20 feet, and the room tight, cabin gain starts at 28Hz, so if the sub is flat to 28Hz you're OK, cabin gain will fill in below that.

Right. So if the XS15 is 3dB down at 26Hz as advertised, with a long, slow 8dB per octave rolloff... in a tight 20' room, like the OP's may be, one could reasonably hope for very deep extension at pretty high levels.
