Subwoofer(s) thoughts/ideas

last year my old high school sound system died so i went out to put together a new system. I ended up at Safe and Sound in Chicopee Ma. the guys there were great and helped my pick out a pair of klipsch RP-8000fs, a marantz pm8006 integrated amp and a blusound node2i. I feel by now the speakers have had time to adequately break in and are sounding wonderful. I have worked on placement (spacing, position from wall, etc) yet i yearn for more bass production. I realize that the towers only go down to 35hz. so the bass is more of a slap then a punch. so i have been reading and looking around for an appropriate subwoofer(s) to add to help with this bass problem that i have. here are a few specs.

listening pref is essentially 100% music with maybe a movie once or twice a month. I listen to music from when i get home, during dinner, chores, entertaining, etc. so its always on and i am listening around the house. genres are EDM and country with some rock, jazz, classical thrown in.

the space the stereo is in is 12x17 living room which is open to the kitchen 12x12 and the dinning room also 12x12. it is also open to the stairway leading to the upstairs. ceilings are 8ft. floors are hardwood.

I would prefer one sub for now to limp me till two if that is recommended. I have looked at the PSA S15DF, SVS SB3000 and the Rhythmic F15hp. i do know my room suffers from room nodes with the bass i can currently hear so i am also considering purchasing the antimode 8033s-II from PSA if that will aid in producing smooth clean bass. I prefer to have as clean and smooth sounding audio as i can. anyone have a suggestion as to which one i should purchase? would prefer initial purchase to be around the $1000-$1500 mark if possible. unless we discover that I should wait till i can acquire more funds for an adequate system or chest thumpers.

I appreciate any advice you can all give.

Thanks,

J.

If your speakers do deliver on their advertised 32Hz +/-3dB, then a subwoofer may not be extremely worthwhile for all music usage. Down into the low 30Hz range will cover the vast majority of bass in music. If you do get a capable sub in your price range, the Monolith THX Ultra 12 or 15 would be a great option and one of the cleanest sounding subs you can get.

Subs>RBH I-12e/I-12. HSU VTF-15H mk2. Monolith THX 12(x2)/THX 10(x2). XTZ 1X12. SVS PB-1000(x2). Speakers>JBL 270/235c/230/225c, Arena 130/125c. Jamo S807/S803. Infinity P363/163. Sony CS3/CS8/CS5. QA 3020i/3090Ci, 2020i/2000c. Monolith Cinema 5 bs. Polk RTiA1/CsiA4. Other Audio>Sony MDR-Z7m2, WH-XB700, XB32, XB31. Sennheiser HD58X, HD4.50, PC37X. SIVGA SV004. HyperX Cloud PS4 HS.

well for edm the sub can help alot...for most country/rock maybe not. if you can fit a rythmik fv18 I would look at that...I own a fv15hp and needed more in a very large space.

I'm not familiar with a wide variety of subs, but I wonder whether a ported sub exists that would be as good or better for music than some of the sealed subs you're considering. Servo subs like the Rythmiks are supposed to be well controlled, including ported versions.

Another option to flatten the sub's response would be a miniDSP product. https://www.minidsp.com/products/min...minidsp-2x4-hd It has the advantage over the PSA unit of handling 2 subs, should you ever go that way. Whether either is markedly superior to the SubEQ feature bundled with Denon or Marantz AVRs that have Audyssey XT32, I don't know. (SubEQ is limited to ±9 dB in flattening sub response. A 9 dB boost ought to take a serious bite out of a sub's headroom.) SubEQ is what I have used, so far.

If you want a good price/performance ratio, consider the Hsu Research VTF series. They have 2 ports, but can be configured as sealed, 1 port open, or 2 ports open. You may not get the exact performance of a sealed sub, but you'd have maximum flexibility. The main down side is that a VTF sub is larger than a sealed sub with the same driver size. (They also sell the compact USL-15 Mk2, with a 15" driver.)

So i have a lead on a pair of PSA vented 15"s they are only a year old and a decent deal. im assuming two 15" subs should help balance the amount of sound throughout the house as opposed to just one. also output would be increased which is never a bad thing. back in high-school i was in a 12x12 room and used three 10" subs and that was barely enough bass IMO for some of the EDM drops. I have certainly reached the limits as to what the RP-8000fs can handle for drops and its rather disappointing to miss out on that part of the music.


how do you like the FV15hp? I am a fan of the servo sub as i certainly like low distortion. that being said there are other very well respected names that do not use servo subs so i assume the difference is not that great.

How much is the seller asking for the PSA pair?

My humble main system:
Vizio M75-E1; Oppo 203 universal UHD player; Denon 4300H AVR, Dual PSA S1801's; Monitor Audio Silver RX-6 mains, RX center, and RX surrounds; one pair NHT mini Atmos speakers; Home-built HTPC (Xeon E1230, 16gb RAM, Crucial M500 480gb SSD, GeForce 980Ti, Corsair CX600, CoolerMaster mini-ITX case); Roku Premiere+; Amazon 4K Fire TV

That's pretty good, and you would be hard pressed to do better at the price. PSA's 5 year warranty is transferable, and their customer service is second to none! I would pull the trigger on those!

So you people are not even going to mention the SRX818SP at this price range? I see one for 1100 bucks (500 under MSRP) on ebay in New York, a stones throw away from OP. Shame on you guys :P

One drawback with the SRX818SP is it only extends down to around 35Hz (the same as your mains). You might want to consider something that extends a little lower to give you that little extra kick considering your taste for EDM. It will also serve you better for the occasional movie viewing sessions.

Yeah, definitely need something that extends lower. the klipsch sound great to some of the higher low frequencies. but there are some drops and notes that they are struggling on. not that i blame them. For two 8" drivers per tower they dig decently deep. Im looking for something that can get to 20Hz without any problems. I also like a good amount of bass so some kind of correction would prob help. I am thinking the anti-node would be a good start.

bear in mind that 35hz is the -3db point on subwoofers with 141db peak output. And built in DSP, so you can just select lets say the output at 20hz and then bring the frequencies above that down to the same level as you have on 20hz (which will be respectable given the enormous room gain you get from two 18" woofers).

FWIW, I listen to a wide range of music and EDM is one of them. There were a few things that annoyed me when auditioning subs while listening to EDM. Some subs have a noticeable delay behind my speakers. Some subs are "splatty" and not short and tight. The bpm on EDM music is high so you definitely want something short, fast and tight. Otherwise, the lower notes start sounding like one long tone. It just sounds messy to my ears.

My recommendation would be a REL in your situation for a couple of reasons. You primarily listen to music and the high level connection integrates well with your speakers. When dialed in correctly, it should sound like an extension to your speakers rather than separates. Perhaps you could stop by at a Best Buy just to audition a T9i, S3 and/or S5 to get an idea of the ranges. Not sure if the Best Buy at Holyoke have them but may be worth a visit as advice on this forum is one thing but actually listening to them will give you the best idea of what you want. Aside from Best Buy, there are only a handful of dealers throughout MA that sell REL.

Which subs did you audition before settling on the REL? I am seriously considering Rythmic F15hp or the F18hp, PSA s1510DF or S1811, and SVS SB3000. Im wondering if you compared to these subs at all?

I have to say i disagree. I have the previous generation version of his speakers, and while they do sound great, they sound even better with my Rythmik subwoofers. My "critical" listening is almost all music, heavy on the classic rock and pop, also multichannel music which has often had the bass mixed in louder than the original stereo music(Kick sounds totally different because of this, not sure I'm a fan).
Never heard the Monoliths, but from everything I've read here, they seen to a legit competitor to Rythmik sound signature wise.

Don't forget to get an ART cleanbox pro or equivalent to boost and convert the unbalanced signal to balanced, learn how to use a dsp, and JBL doesn't claim 141 db output on these. Also, the one you mentioned has one driver, not two.

You might want to consider the FV15, since you are listening around the house, it will do a better job of pushing the low end around. Where are you located? If anywhere near Austin, TX, you could buy one, see if you like it, and return it yourself(and save the shipping fees on the return). My guess is you'll like it. I think the Monolith 15 is also a good suggestion, as all reports I've seen is that they have very clean bass as well. I'd trust Rythmik's CS over Monoprice, though.

Yes, I have two of the f18, but my room, while largish, is sealed, it sounds like you are trying to fill your whole house, which is why I suggested a ported model. My room is about 20x20x7 1/2 feet in the basement, so concrete floor and two of the walls. Sounds great to me, but I've only heard 3 different subwoofers, all sealed, so don't have a lot to compare with. While REL seems to be a good brand, I seriously doubt they have anywhere near the price/performance of the others being discussed, and I doubt they are any "cleaner" than the Monolith or Rythmik subwoofers.
If you do have a sealed room, that definitely puts the sealed models back in contention. Remember, the "Official AVSforum rule" buy the biggest you can fit/afford now, and buy another when you can!

Ahh, mixed topics for a bit. Two of those will match the dual one.

All the rest is good advice. I would add learning to use REW.

Lack of midbass. Most bass notes (apart from artificial made-up notes in for example rap music) tend to have a much quicker "attack" then followed by the deeper bass note. Without subwoofers that reach up into the midbass, too much sub-bass will sound wrong. For example it will be like you cut out the initial kick on the kick-drum, and only hear the following strumming when the pedal comes off the drum surface. Like hearing only the echo of a clap instead of the clap itself.

Does anyone happen to remember who has those epic midbass enclosures in his already insane sound system with many 18" subwoofers? He can back up this point.

Midbass is a very growing realization in sound circles that have maxed out on sub-bass. Even professional car stereos these days are beginning to get 10" woofers for midbass to bridge the gap from the 18" subwoofers. Even though its a royal PITA to add 10" woofers in car doors.

I feel by now the speakers have had time to adequately break in and are sounding wonderful. I have worked on placement (spacing, position from wall, etc) yet i yearn for more bass production. I realize that the towers only go down to 35hz. so the bass is more of a slap then a punch. so i have been reading and looking around for an appropriate subwoofer(s) to add to help with this bass problem that i have. here are a few specs.

listening pref is essentially 100% music with maybe a movie once or twice a month. I listen to music from when i get home, during dinner, chores, entertaining, etc. so its always on and i am listening around the house. genres are EDM and country with some rock, jazz, classical thrown in.

the space the stereo is in is 12x17 living room which is open to the kitchen 12x12 and the dinning room also 12x12. it is also open to the stairway leading to the upstairs. ceilings are 8ft. floors are hardwood.

I would prefer one sub for now to limp me till two if that is recommended. I have looked at the PSA S15DF, SVS SB3000 and the Rhythmic F15hp. i do know my room suffers from room nodes with the bass i can currently hear so i am also considering purchasing the antimode 8033s-II from PSA if that will aid in producing smooth clean bass. I prefer to have as clean and smooth sounding audio as i can. anyone have a suggestion as to which one i should purchase? would prefer initial purchase to be around the $1000-$1500 mark if possible. unless we discover that I should wait till i can acquire more funds for an adequate system or chest thumpers.

I appreciate any advice you can all give.

Thanks,

While speakers only care about there physical location, to your MLP. A sub/s will try to fill all open spaces.
The space the sub/ s will try to fill is 3936^ft, for your living place.
Therefore, my suggestion would be spending your $1000-$1500 budget. On one sub at the moment, and get another one down the road once the budget recover.

While I am Bias toward Port design, been 99% movies. In your case a good Seal Design quality may be best for you, since you are 100% music.
Just some word of wisdom, before making a decision.
SVS, PSA and Rythmik, are all well regarded around these various thread on this Forum.

Full disclosure - I don't know everything there is to know. I am not an "expert." I could be wrong (just ask my wife). BUT:

I *think* a subwoofer can and will do more for him than *just* extend his frequency response beyond 35 hz. Here's how I think of it - if you cross over into a a subwoofer up at 80 Hz (below which sounds are omnidirectional to our ears), you allow your speakers (his look like they're capable of 150 watts RMS) to focus/use those 150 watts to do the best job they can at frequencies above 80 Hz. Those lower frequencies require more energy/power to play anyway, and by buying a separate sub with it's own amp, you free up the speakers (and the Watts from his Maranrz) to do what they do best and let the sub do what it does best...

Now I know it's not a hard/abrupt change from 81 Hz in speakers to 80 Hz in the sub... There's a "slope" where the handoff takes place (I think in units of db/octave), and when you set the crossover to 80 I don't fully understand if that's the start of the handoff, the end of the handoff, or an "inflection point" in that slope... Again, not an expeet.... But + or - 3 db rolloff to 35 Hz means he can see improvement by crossing into a big capable sub (15" Rythmik?) above that, as the Rythmik will have no roll-off at 35 Hz and won't begin it's roll off until below that....

That is sound reasoning, putting a highpass on speakers will free up wattage headroom so they'll run cooler and have less power compression (power compression = lower output because heat increases voice coil resistance, so fewer amps gets through).

In a lot of circumstances it will also reduce noise if you're running your speakers at such volumes that they start to produce considerable THD+N (assuming of course its your low end frequencies where the bottleneck is, if your tweeter/compression driver is woefully undersized then you're still buggered in THD+N).
