KICKER UnMASKED Shorts - Why Use Passive Radiators? 

Great idea making these into clips!

I had the Camaro kicker box back in 95. Had two 12 subs and two 10 passive radiator. That thing was impressive on kx amplifier I had . Was loudest in high school. Everyone loved the sound that came from it.

I own a 2004 S10 crew cab. There is no room for anything! I took the chance and bought the 6.75" version of this box. I had to cut out the jack holder behind the rear seats to make it fit. I have to say I am impressed with the output of this little sub. It won't rattle the neighbors but in the cab it's awesome. Much more bass than I expected. I recommend!

I have a kicker 48TRTP102 on the back floor of my 2020 F150. It's powered by a JL audio vx1000/5i amplifier. It took me a bit of time with the amp to get all the crossover frequencies and filter curves just right, but when all was said and done, that kicker box THUMPS. Like a lot of pick up truck owners, I wanted to add a sub, but didn't want to give up a ton of space in the back. I really wasn't interested in a "behind the back seat" sub, as there's not a lot of options, and I needed that area for the amplifier. For those of you who may be wondering "does the 10 inch model really put out that much bass?" It most certainly does, and it fits nicely under the back seat when it's folded down. Worth noting...the enclosure is SOLID. You're not breaking that thing without specific intent. These shallow kicker boxes are legit. Plug and play bass all day.

I had the hatchback 8” full range speaker system with 2 10”passive radiator on the bottom back in the early 90’s.That thing slammed and those horn tweeter really screamed.

When I saw the title I was expecting this to be a RU-vid "short.". I was curious to see how you were going to adequately explain passive radiators in just a few seconds.

I'm so glad you posted this. I'm about to build a box for two 12s under my back seat but I'm under the sqft I need. This will definitely be my option instead of a seat lift. I hope TERM-PRO can adjust for this. Thank you

I have a Comp Rt 12 1ohm in my enclosure. Thank you Boys!!

Very good Info !

A lot of people are confusing ported speaker boxes are louder, more powerful than sealed boxes. This is not true. Back to the past when I studied electronic courses at Devry University, a speaker driver in a sealed box sounded much louder than without a box. The main purpose of a ported box vs a sealed box which can give you the lower frequency response. Passive radiator is a substitute of ported one but a smaller speaker box.

Good video Man. Can you link me to the exact configuration of that kicker box with sub and passive radiator

I'm planning on getting the 48TRTP122 12" box for under seat in conversion van...how best to mount it?...Thanks

Pretty please release the TS specs on your passive radiators❤. Fun fact I took your 8” truck box passive radiator and drilled a hole in the center and added bolt and washers for weight. Took it from your 49hz down to about 38hz. It has a much wider range now and less peaky.

I love it. You're maximizing the quality and level of output out of a small package

When will the 48TRTP122 be in stock again?

Great explanation.

I Bassed this in 1990... lol loved it!

I'm shocked the phase relation isn't 180 causing the postive motion on the speaker to cause a negative motion on the passive equaling no positive sound pressure. It clearly works as I've seen it working.

I always wondered if this specific box would fit behind the gladiator backseat

Ok so I have 2 compr 8’s and thinking about building custom fiber glass boxes. Can I forward fire the sub and down fire the passive radiator? Odd question but i see it in home audio but never on car audio

Would there be any negative effects if I replace the passive radiator with an additional comp rt subwoofer. Looking for a small enclosure with the most bass.

I had 2 of these 12inch subs in a down fire box ran off a DX 1000.1 amp. Someone broke into my truck and stole the box. I need to replace it now. Would this in your 12 inch down fire be ok hooked up to the DX 1000.1 amp?

What about the comp c 10 in

Is there a square passive radiator for an 8” l7t? I’m trying to get deep low end extension in a thin inclosure 4” 0.45cubes.

We need a 15in version too! For even lower tuning.

im looking for a good 10 inch woofer for mainly rock & metal music im accustomed to a 12" alpine type R and a random pioneer 10" i picked up second hand. id like a 12, but dont want a big box. a standard 10 suits my needs perfect but id also like to get something shallow. looking for tight response but also the ability to keep up with volume, AND be shallow, maybe even down firing

Which would hit the lower notes and still have punch? These with the passive radiators or your L7T boxes?

I know it says to use a compatible subwoofer, but what if I used another brand subwoofer (I have a 10" dvc RF) - would it still work?

Do you lose snap with these? I currently use a sealed box because I love fast, snappy, hard bass. Seems often than not a ported box starts to flutter with a decent stretch of fast bass. Can sound kinda muddy. What are your thoughts? If I can keep the snap and increase bass volume maybe I'll give it a shot.

I have just got my first Kicker product and the 48TRTP122 12 box for my Infiniti QX56. The 2 Ohm version is good but not had deep and consistent as @ 500watts. The Old Rockford Fosgate 12 with the amp sounded much better and cleaner with bass. I am going to let the break end period to see if any improvements are made. Kinda sad for me

I have the CompVT12 box from 2007. It's a week before 2024 right now. It's still playing all these years later. I have it hooked up to the same Alpine Amplifier I bought when I got it so long ago. (The Amplifier was on sale. I couldn't beat the price) Very high-quality products. The CompVT box only has a woofer, and the enclosure is sealed. It's designed to fire into the back of the drivers seat. In my S-10 it worked perfectly as you could slide the box all the way to the cab corner. However, I got rid of that piece of junk and got a Ford Ranger in 2012. ( I'm still driving it, now. Much better truck). The Ranger has speakers in the back, so you can't slide the Kicker box all the way to the corner. The woofer fires from the middle between the seats at the armrest. This particular box doesn't work well like that. It was designed to be behind the drivers seat, so I can only cross it over to about 80 hertz before you start getting noises you don't want. The Ford cab rattles, A LOT, compared to the Chevy. I'd like to get one of these designs or the newer L series, but my woofer just won't wear out and give me a reason to buy another one!

What’s the best amp to use with the Kicker 48TRTP122? Should I use the Kicker Amp 46CXA4001 or the Kicker AMP Kicker 46CXA8001?

I have the 8 inch version in the wife's Ford edge..very nice job..I like it a lot.

Could you cut the box in half, make it deeper to keep the same air volume, and put PR on the back of the box?

What are the tuning hz of these in the 10in and 12in version. I like bass around mid 30s to low 30s.

What happens if u use a pr in a larger box, say double volume but everything else is the same (pr mass, same woofer...)

Is it possible to pair 2 12" passives with 1 comp q 12" in a 1.4 cu ft box?

The physics is counterintuitive but they are NOT negative-phase to the enclosure's active driver. They are within 90° of phase and so can be mounted on the front baffle without excessive damage to the output's phase.

Would this fit behind the seat of a toyota tacoma 2017

Can you help me design a 4th order using a passive radiator?

Passive Radiators also make amazing Beardie Trampolines

Doesn't the passive radiator need to have twice the displacement as the driver?

Please make the kicker super 2 box again

why no square passive radiator version?

Looks great ,maybe they could have added grill covers so the 2 do not slap into the seat🤔

Would it sound awful if I remove the radiator and install another 10”

Can I run 1ohm skar amp on set of 2 43TCWRT82?

I had and original kicker box by Stillwater Designs. mid 80's

wished I've seen passive radiator at my first and only DIY car sub 15 years ago. I did not like the port noise besides I found 12 inch and 400wrms to be too powerful for my taste.

💪🏼🔊

U guys need me to design subs w/ passives, I got 2 - 4 1/2 in subs with 5 passives and it sounds better than most peoples cars that haves 1 good 12

What about the 12 inch square sealed compared to these?

Gracias homies

Makes sense 🤔

The first few words....loooooool 😆

I bought one of this box and after E months it got cooked speaker coil was fried

Makes me wonder how 2 active drivers would compare in the same enclosure...

What u mean 180 degrees out of phase

I told the guy the subs don't match I can't buy them😂

I own a pair of those kicker 12s with a passive radiator 12"

I liked the video, just because I didn't have to watch an ad.

So basically a passive radiator is a fake subwoofer 🔊?

Someone who wants to experiment should use a regular driver and use it as a PR. The tuning could be done by adding high power resistors on the poles of the driver🤔🧐

Nice little set up. Kinda pricey though

Mines blew out in less than a hour 😆

Ported > passive

passive radiator??? means to lower the cost or budget for maximum happiness.

Displacement laws of physics disagree m8......it kicks at the same time as the driver bro 🤦‍♀️🤷‍♀️

500th like yup

Passives were invented in the 30s 🤦‍♀️🤦‍♀️🤦‍♀️🤷‍♀️🤷‍♀️🤷‍♀️

Next video should be why not to buy kicker

Nothing cool about these port's are better because when I put my ear up on the hole my ear begins to Ring. And if you're not smart enough to get a Port in a box like that then why are you in the business kicker sucks anyway.

hahaha it looks like it has a black eye

More bs scam
