I was thinking of getting 2 of those to add with my 2 SVS PC4000$ but SVS said i should not mix different subs together. Like you said in your video that you can turn then down and have tons of head room so do you think 2 of those D8000 pro and my 2 SVS PC4000s will be too much for my 2 bedroom apartment Lol ?????????????....no one lives above me next to me just below me and im in a solid concrete building. And do you think it's ok to mix and match different subs for home theater. Thanks i love the channel and i never miss any of your videos so keep bringing more great content that we all enjoy 🍿🎬 💪

[@SpecOfTech]

@@rickguenther1013 Thanks brother, I appreciate you watching. Generally speaker, SVS is right. It's always easier to, and recommended to use identical subwoofers. You can run into issues when mixing subwoofers that are tuned differently. It's not to say it can't be done, but typically you will need to put in some effort to get them to play well together. I would recommend just getting 2 D8000 Pro, and possibly selling the PC4000's. You will get significantly more output from the 2 D8000's than you are getting from the PC4000's. You could try and mix them together to see if you like it, but there should be no need to keep both 😉. Hopefully the neighbors that live below you are cool people, because they might feel some bass lol.

[@rickguenther1013]

@@SpecOfTech thanks for the fast reply ya i really don't want to try to mix up different subwoofer brands but i also don't want to get rid of my PC4000s so i guess i will just buy 2 or 3 more PC4000s and that should be some crazy output 😂 Lol. I just love my Tonewinner at300 that you got me interested in so i was thinking of saving some money and getting some Tonewinner subs that are alot cheaper in price then anything SVS. And ya my neighbors that live below me are cool as long as i don't bump tunes or movies past 10pm Lol. My 2 PC4000$ sound soooooooooooo good and they don't take up any space so i can fit a few more of them in my apartment until i buy a house in the next 6-10 years where i can enjoy it as loud as possible. 🍿🎬

When you demo these are you pushing them to the max to get that much cone movement? Is it a setting that you would in a everyday setup to blend with the rest of the setup?

[@rasta.j]

Just picked up the D8000 (non pro), instead smaller cabinet, and opposing 15s rather than both front facing. Same amp and cones etc. Got it for $1250, the bass is massive even when the cones arent moving like in this video.crqzy good price for what you get

[@christopherglass1206]

Hi Bear I have to a simple bar mind numbing question to ask...ok here goes, I have heard and read that to hook up a sub put the cross over on full and let your receiver control the cross over, in other words crank the cross over on the sub to full and let your AVR on set up control the C/O (set the c/o on the AVR to say 80htz) or set the c/o on the sub to 80 htz. Now that I have confused you, imagine my confusion! Sorry a basic question but I need clarification or HELP 😂 oh I should mention that I am running it all connected to LFE (Denon AVR, Klipsh sub) Hoping a fellow Canadian could help😊

[@Pete.across.the.street]

That's correct let the avr do the work

[@SpecOfTech]

haha no confusion, it's all good. Yes, you want to turn the crossover on the sub all the way up, some even label it as "LFE" if you are using an AVR or Processor to crossover your subs to the speakers. Setting your crossover in the head unit to 80hz is the Dolby Atmos standard, but don't be scared to play with that crossover point a little to see what you prefer. Sometimes listeners prefer a higher crossover.

[@evanwelder]

Definitely looking forward to your thoughts on pb17 ultras

[@Professor5180]

I've heard that Ryhmiks have zero port chuff. It has to do with the servo tech in them. I've even read how someone went from sealed SVS subs and was worried about going to ported Rythmiks and the Rytmiks ended up suprsining him as they were even more musical and tighter. 'Polk Fan' has a great channel displaying ported Rythmiks. If I was worried about port noise that would be the brand I would look at. On another note it is baffling to me the weight of these subwoofers. A pb 16 ultra weighs 175 lbs and the new PB17 ultra weighs 165 lbs. Then this dual 15 inch D8000 only weighs 187lbs. I just find that the pb16 is overly heavy for some reason. Great video!

[@stevenfox5250]

The Rythmik FV18 has 3. 3.5" ports. With all 3. 3.5" ports open the tune is 16Hz. With 2. 3.5" ports open the tune is 12.5Hz. Ho estly, the Rythmik doesnot have enough port area - i am not impressed. But i am also not impressed with the SVS PB16 - not enough port area either. And not impressed with the Monoprice 16" - with 3. 3.25" ports open the tune is 16Hz. None of those subs have enough port area. You need like at least 3. 4.0" ports with 16Hz tune for there to be sufficient port area. 3. 4" ports tuned to 16Hz - that is enough port area. 3. 3.5" ports tuned to 16Hz - that is not enough port area. 3. 3.25" ports tuned to 16Hz - that is not enough port area.

[@AlexGtheDon]

I have seen quite a few of your reviews and I think they are awesome! But I am curious, if you are rating great budget subs, have you ever considered reviewing the Monolith M-215? That is an amazing sub for the money $2499, and when it’s on sale, has gone for as little as $1299 or so. I picked mine up last year at $1525. AMAZING sub. It is THX Ultra rated, but IMHO should be Dominus rated. If you see the spec sheet it pegs 122.5 dB and goes down to 14HZ!

[@SpecOfTech]

Thanks man, I appreciate that. I have tried to get the Monolith subs for review, I haven't had any luck yet. They are a great performer for the price, no doubt.

Btw. I always like your sound clips and in room measurements!! It’s very useful when especially when you compared different subs! 🎉 ps. That rattle is intense!! Have you tried everything to dampen that down somehow? Just curious 🎉

[@SpecOfTech]

I'm glad you find the helpful. If I silence the rattling, how will I know if the sub passes the rattle test😜 . Honestly, the rattling doesn't bug me, because it's mostly only audible when I do crazy loud demos. During normal movie watching it's not audible in 99% of scenes. So, to answer your question, no I haven't tried to silence it lol.

[@FrankBennett-kb7xs]

Lower the Low pass filter..That will help with frequencies that excite resonances and rattles...Subs combined with full range speakers shouldnt be crossed any higher than 50 HZ LR24 DB.

[@SpecOfTech]

Thanks for the suggestion. When I have full range speakers, I only use them as such for 2 channel music. For home theater, I like the subwoofer to handle some of the bass above 50hz as well. I find even though the speakers are full range, a subwoofer still sounds fuller IMO. Matter of fact, some subwoofer designers even recommend trying a 90-110 hz crossover. I know my room sounds bad when things are cranked to 11 lol, but during normal movie watching levels, it doesn't sound like that.

[@thehavok4258]

Why any manufacturer uses ports on any home speaker is beyond me. So many negatives for what... a couple % more bass output that isn't even good bass output. Keep it sealed it's tighter, more accurate, less muddy, more damping, no port noise / chuffing, tonally superior.. Its just better in every single way with the same driver and amp... Only real downside is needing a bigger box for the same tuning. Unless you're building a theater in a 500 spft studio you should be fine.

[@SpecOfTech]

I appreciate the comment, but not everything you stated is accurate. What is tighter to you? How can a subwoofer sound tighter? There are many common misconceptions with ported and sealed subs, that is one of them. The only time a ported subwoofer sounds "muddy", is if it is poorly placed and/or poorly eq'd. This also applies to a sealed subwoofer, they are not immune. Another one is that a sealed subwoofer is "cleaner". When in reality a sealed subwoofer is less efficient, and technically, adds distortion. The driver is fighting against the air pressure in the box, it works harder, it adds distortion. I do agree with your statement on the port noise and chuffing. That is a specific problem to ported subwoofers, but, sealed are not without their drawbacks either. Like their lack of efficiency, they can't produce the same output as a ported if it's apples to apples. I think you can expect more than a couple % more output with a ported subwoofer. A ported subwoofer can have significantly more output than its sealed counterpart, depending on port tuning of course. That doesn't apply to all frequencies, usually a sealed subwoofer will catch up to its ported counterpart in the higher frequencies, but again this depend on port tuning. I have had conversations with multiple subwoofer designers, and generally speaking, they have said "if you have the room for them, ported subwoofers are superior". I'm paraphrasing. Cheers!

@@SpecOfTech Woofer tightness isn't an arbitrary term, you and I and everyone else knows this. Tightness or accuracy is used to define how much control the driver has over its cone (execution and correction). Muddiness and inaccuracy mean the driver has less control over its cone and takes longer to execute and correct (sloppy / inaccurate movement) resulting in sounds and tones bleeding into each other, creating sound when it's not supposed to and less able to produce the sound it is supposed to on time. All things equal, smaller drivers are more accurate because they have a smaller, lighter cone with the same motor force resulting in faster execution and correction of the cone. This is why smaller subs are known for being tighter. All things equal, bigger drivers take longer to execute and longer to correct, this is why bigger will result in less accuracy or tightness. Sometimes so much so that the bass is completely out of phase from the rest of the sound coming from the highs and mids. All thing's equal, sealed subs are more accurate because the enclosure creates vacuum when the cone is pushing out and pressure when the cone is pulling in, always trying to achieve equilibrium. Resulting in faster correction (more important than execution) All thing's equal, ported subs are less accurate because they are closer to free air on both sides. This means the cone has less vacuum when pushing out and less pressure when the cone is pulling in resulting in it taking longer to correct which creates inaccuracies and muddiness. But has the added benefit of executing faster (less important than correction). Doesn't mean they'll be muddy or inaccurate garbage. It means they are MORE muddy and inaccurate. Key words there. Take the same driver with the same amp with proper box design under a slow motion camera and the sealed box will correct much faster, this is why sealed subs are more accurate under normal use. This is why servo subs exist, because ports create slop and the servo is to correct the cone much faster than it could on its own in a ported box. "if you have the room for them, ported subwoofers are superior" - That doesn't mean anything. Superior to whoever told you that can mean higher output at only 30hz, which is right, you can do that with ports. Ports do not increase quality. And this doesn't make sense because sealed subs are bigger at the same tuning, you go ported to save space. The only reason manufacturers of high end home subs make ported subs, is to reduce size (by a significant amount). Because a sealed sub tuned the same as a flat to 16hz ported sub is absolutely massive, it's like 2-4 times the size.

Hey buddy great review and love the measurement graphs. Question. I have the D8000 and soon want to buy one more sub. I'm thinking the D9000 or D8000 pro. Would it suit the D8000 or blend well with it or will it not match and should I stick to another D8000?

[@SpecOfTech]

Thanks buddy. It is always best to pair 2 identical subwoofers. I suggest you go with a second D8000. If for some reason you are unable to do that I would recommend going with the D8000 Pro, at least the it has the same drivers as the D8000. They aren't tuned exactly the same, so you may run into some issues at port tunings. With room calibration it should help this. But, who knows, sometimes subs seems to work well together even without too much intervention. Hard to say until you place them and measure. I hope that helps.

[@HorsepowerAddiction]

@@SpecOfTech thanks for the reply! I can go with a second D8000. The reason I was thinking to go with the pro or 9000 was for the extra output power. Would I notice extra power with one D8000 and one pro over two D8000's?

[@SpecOfTech]

@@HorsepowerAddiction It may be somewhat noticeable at some frequencies. I believe the D8000 Pro has a larger cabinet, so that will help with output also. I'm not sure how noticeable it will be. You could always try to pair them and see how it goes.

Im upgrading my Nakamichi Dragon subwoofer. I ordered 2 Nakamichi 12 inch subwoofers for $2400 and 2 Elac Rs 700 for $3000. The one that sounds better im keeping. I'm new at subwoofers because the initial subs that came with the dragon didn't reach advertised Hz of 20hz and was bottoming out at 35 Hz. I didn't know how important that was until many people began to complain about them. It couldn't play edge of tomorrow without bottoming in the original Nakamichi 8 inch subwoofers What the Elac Rs 700 has over the Nakamichi 12 inch is fantastic room correction.

Why would you go with either of those. Neither of those choices are good. You'd be better with RSL Speedwoofers. Or if you have the space, some HSU or Rhytmik.

[@SpecOfTech]

I would recommend looking at either something like these Tonewinner subs, or like Robert mentioned, look at HSU or Rythmik as well. They will all out perform the Nakamichi and Elac subs. But let me know which one of those you prefer after you get them.

[@MattyDaddy14]

I second that… I’ve done a ton of research and the RSL Speedwoofer 12S will blow those away at only $799 each! Also the RSL has hi level inputs that you’ll need to do the nakamichi “sub mod”. Unless you do a hi-lo converter, in which case you could get 2-tonewinner 12”s for $1600 and have good dsp, or even starke sealed or ported 15”s ($549/$999)!! 🎉 If I had that amount to spend, I’d do the hi-lo converter and get 2- D6000 15”s for like $1300 each because for that price point, it has a good dsp and awesome output plus way more reliable than monolith. Otherwise it’s gotta be 2 RSL 12’s or starke 15P! 🎉

If you want a lot of low end output, JTR is a fantastic choice and is really hard to beat. But it doesn't beat the D8000 Pro and D9000 when they are measured together. Except for maybe below 10hz.
