Overview

Our take on the Polk Audio Atrium Sub10

The lack of walls and other reflective surfaces can make outdoor speakers sound thin and tinny. But now you can add some real low-end punch to your outdoor music system with the Polk Atrium Sub10. This all-weather subwoofer features a 10" driver to deliver the deep bass frequencies that typical outdoor speakers just can't handle. Connect the Sub10 to your receiver or amplifier, and you'll enjoy fuller, richer sound at all your cookouts and outdoor gatherings.

The tough resin enclosure sports a terracotta finish that you can paint to match your deck or patio décor. And it supports up to 200 pounds, so you can use it as a plant stand or an end table.

Polk designed the Sub10 to perfectly complement their Atrium Sat30 outdoor speakers, but you can use it to add punchy bass to any outdoor speaker system.

Purchased this subwoofer for the back deck. Hooked up easily. Sounds great. Most folks cannot tell where the speaker is.

Rich sound from Sub10

Kris from Huntington, NY on 9/9/2016

Crutchfield Customer Review (What's this?)

I added the sub10 to my 5 Atrium 8s in my backyard / pool area and I agree with a lot of past reviews. The sub10 definitely richened/ added warmth to the sound. It's not bone shattering but that's ok. I can't really crank my system because of the neighbors. It was a very easy install. The wires were labeled very nicely. Where I placed it no one sees it and when they do they don't know what it is and don't realize the sound coming from it. The optional grill should be standard and come with the sub10. I had no problems getting it from Polk but it should be included. Overall I am very happy with it and do recommend it.

Pros: Good sound, easy install.

Cons: Optional protective grill should be a standard and come with it.

good sub

garry j from manhattan, IL on 7/27/2016

Crutchfield Customer Review (What's this?)

have it on deck by pool with 4 bose 251 otdoor speakers, which by the way are fantastic. It is a very nice addition to them. it's not bone shaking but I didn't want that. I am using a 200 watt reciever not an amp which if you did use an amp with it's own sub output I'm sure you would get more out of it. I do not have a seperate sub output. So why not 5 stars? because for the price polk should incude the speaker grill and good luck finding one. I made my own

Pros: nice addition

Cons: no grill you have to buy seperatley, and every one where I looked online were sold out

great bass response

jason from claremont, nh on 7/21/2016

Crutchfield Customer Review (What's this?)

should have ordered the speaker grill at the same time so I will now have to order separate, it has about two feet of wire cord coming out of the sealed unit, L+L-(green/white) , R+R- (red/black) inputs, I installed bass blockers ( 133uf axel lead non polarized caps) in series with my two existing small speakers so the bass would not distort them and it sounds great. speaker grill should come with this unit as much as it costs.

Pros: easy hook up and installation, only took 30min

Cons: needs a speaker grill to protect subwoofer from rodents and critters

Atrium Sub

Josh L from Blue Springs, MO on 6/5/2016

Crutchfield Customer Review (What's this?)

I bought this sub to go with the Atrium 6 speakers. They are a perfect combination! You get your highs and miss out of the Atrium 6 speakers and you get your lows from this Atrium Sub 10. When my friends and family come over now, they are quite impressed with the quality of sound coming out of all of these speakers. I am pretty impressed too.

Pros: Crisp sound. Fair price. Paintable to match your outside landscaping. You can secure it down so that it doesn't vibrate around or so that it's more difficult for thieves.

Cons: It doesn't come with a cover/grill for the sub. You'll need to purchase that separately. However, I couldn't find a specific Polk grill for this speaker. Another downside is that it's not a powered sub and you cannot control the base from the speaker itself. I would have liked to see some type of control similar to the powered sub.

Polk Audio Atrium Sub10

Tom from Wisconsin on 7/17/2015

Crutchfield Customer Review (What's this?)

The Polk Atrium Sub 10, was very easy to install. The sound is second to none. I have it paired with Bose Free Space® 51 environmental speakers, and the balance of sound is outstanding. I have the system powered from a Denon AVR-X4000W receiver Zone 3 and a Niles SI-2100 amplifier. The terracotta finish looks like just an extension of the potted plant on top of it. I can honesty say it is wife Approved! I did not not think I needed the sub-woofer, but I am glad I added it to the outside system.

Pros: Dual voice coil adds a full range of sound

Cons: None

Bob O. from Maryland on 6/23/2015

Crutchfield Customer Review (What's this?)

I have been very impressed with the bass provided by the Polk 10" Sub. I have a large outdoor pool area and used 2 10" subs that fill the whole area with good sound. I think that placement along walls and some distance from each other helps a lot.

Pros: Great sound. Easy install.

Cons: None.

Outdoor sub

Soundguy from Dallas TX on 5/16/2015

Crutchfield Customer Review (What's this?)

So I needed a sub to compliment my kicker outdoor speakers. At first I thought the sub was powered and after opening it,, realized it wasn't. Guess I should have read it a little closer. Anyway, I have the sonos connect amp. It's connected to the kicker speakers and I combined the sub in line with both speakers.(the sub has left and right speaker connections). For my 50x60 backyard, the 3 speakers rock! The sub seemed a bit overpowered or rattled by the amp, so I turned the bass down a touch and now it is perfect. Maybe I need to mount it to the ground or weigh it down with a flower pot.

Pros: Outdoor, lightweight, mountable to the ground by twist and lock, theft prevention via and steel eyelet. Decent bass that won't anger your neighbors.

Cons: None that I can think of

Atrium 10

RBx from Katy, TX on 6/16/2014

These can be an excellent solution if you're looking to round out an exterior system on the lows and mid-lows. If you're looking for a bone rattling ultra-low frequency sub, find a powered one that can handle the outdoors. Made to be coupled as a single with satellite speakers, the passive Atrium 10's can really shine if a little thought it is put into their use. I had recently installed a pair of 251's driven by the new Bose SA-4 Wi-Fi amp on a patio about 16' apart and 10' high. The 251's are excellent speakers, but typical of Bose, the SA-4 system (currently) does not allow for any tone adjustment. It took a lot of trial and error pointing and aiming of the 251's to get close to the sound I was looking for and to be truthful the sound is still a hair bright for my tastes. My next task was the same setup on another patio, but this time some 30' apart and 15' high and with a lot more hard tile surface on the ground. Worrying about the sound I'd get led me to this site. I opted for a pair of the atrium 10s driven by their own SA-4. The result is outstanding. I run them at about 85% of the volume of the 251's. In my application at that level you don't realize so much that they are there, but if you turn them off you really do! It's hard to describe their impact on the overall quality of the sound other than wow. Bottom line - a great outdoor "sub", but be prepared to tweak things - especially when using with other brand speakers. Thanks to the previous reviewers

Pros: An excellent solution for me to round out the lows and mid-lows and add an overall "richness" to my outdoor sound.

Cons: Be prepared to tweak things to get the sound you want in your specific application - adding volume control and/or using a pair - especially when using with other brand speakers.

It took 2, but they sound great

Tim from Whiteford, MD on 5/20/2013

Crutchfield Customer Review (What's this?)

I have a double deck consisting of (2) 16x20 decks with a step down between. I have the larger Def Tech speakers on the house and they sound great, but you lose the base as you are on the lower deck so I thought I'd try this. It arrived 18hrs after I ordered it (amazing). At first I wasn't happy and thought perhaps it was defective. They quickly sent me another, but it sounded the same. Something made me hook them both up parallel and WOW. What a difference. Perhaps my area is too big, I don't know. Then I tried them spaced under the lower deck (2' above the ground). Holy cow-what a difference that made. The decks are Trex for what it's worth. Not sure if the sound bounced off too easily when they were on top or what, but having them under the deck literally rocks. We're now experiencing as close to the same quality that I get inside that I think is possible. These have L/R line level inputs and the crossover setting is kind of high, so they sometimes sound like a full range, but that was more prevalent when I had them on top of the deck.

Pros: Superior outdoor sound quality, paintable

Cons: Took 2 of them to get the sound I was looking for, crossover setting a little high for my taste in Sub bass.

Pold Atrium sub10

philip c from Franklin, Tn on 5/18/2013

Crutchfield Customer Review (What's this?)

Good sounding base, but was unaware it required an amp to function and also requires both left and right inputs. I was planning to use the sons sub output single lead.

Pros: Good base response,

Cons: Should come with a grill to protect speaker from elements and varmints. It appears to be available as an option. Requires âmp to drive. they should offer a powered unit for outdoors.

The Atrium Sub 10 filled the missing link

Kevin from Louisville, KY on 1/23/2013

Crutchfield Customer Review (What's this?)

The Polk Audio Atriumn Sub 10 (outdoor sub woofer) filled the gap of the missing link of listening to the Atrium 4 speakers alone. I had four Polk Audio Atrium 4 speakers. They provided a crisp clean sound. However, once I installed the Atrium Sub 10, I was blown away. The performance of the sub woofer far exceeded my expectations. I never thought I would get that much of a deep sound from a speaker outdoors. I have a set of Bose computer speakers and a Bose 5:1 surround sound indoor theatre system. And as far as I am concerned, the Polk Audio speakers out performs Bose in every aspect. Especially when it comes to the value.

Pros: Easy to install. Provided a full rich sound when using with Atrium 4 speakers. The best product for the $.

Cons: Have to spray paint to match patio color scheme. I wish there were 2 or 3 color options.

Happy As All Get Out

Thomas from LA area on 5/31/2012

Crutchfield Customer Review (What's this?)

I replaced my old tower speakers on the patio with this sub woofer and two Bose 151 outdoor speakers. All 3 driven from two old left/right lines from the old hippy-speakers that run into house and straight into the "B channel" of the old 100-watt receiver outputs. Thats the recipe. No speaker switches. No powered sub woofer. No base blockers (don't ask). No dedicated coaxial line. I even tried Bose 251's. Compared to the 151's those were ok. But NOT with the sub woofer. Too much base from everywhere. And not the "good" base. Just that sluggish, low, exhausted sound that only inhibited any high tones from the 251s. The sub is made to run with smaller speakers. No doubt, the "Party approved" Polk set-up, with their Sat 30's is good. Maybe even great. But I already had the 151's. And besides looking good, they deliver the high sounds over a broader area that even the 251's could. If your obsessed enough to have read this far, then you'll want to know: Covered patio 30' X 15 feet, nestled in "elbow" of stucco house. Open on a short end and along the back. 151's placed high up, just under cover ceiling at mid-point and edge of open end (along the long side of house). That's the most occupied half-but placement is subjective. CRUTCHFIELD stood ready to tech-support my set-up, but when the sub woofer came, I found it to be faster to twist wires than punch a phone number. They took good care of me. I will be back.

Pros: Easy set up. Looks good. Go ahead, put a plant on it, really.

Cons: Thank God I'm not audiophile enough to come up with any. You guys need help ; )

Solid Performance

Jerry from Preston, CT on 6/3/2011

Crutchfield Customer Review (What's this?)

I have searched for a reasonalby priced additon to my Bose outdoor speakers as they lacked the bass performance that I want in my system and I finally found it in the Polk Atrium Sub 10. I am powering the sub through the subwoofer output of my Yamaha receiver and a Hafler 220 stereo power amplifier. This allows me to control the output of the subwoofer in order to better blend the subwoofer with the main speakers at all listening levels. I couldn't be more pleased. I now have the sound I was looking for at lower volume levels. We can carry on a conversation while still enjoying great sound. If you plan on using the sub as a passive subwoofer, I would recommend the entire Polk Atrium system as I am sure that they are designed to perform best together.

Pros:

Cons:

Provided the sound depth I was looking for outdoors.

Crutchfield Customer Review (What's this?)

I have a set of Bose 251s set up on my underdeck patio. These speakers alone did not provide the outdoor sound that I was looking for. I debated for months and months on what type of subwoofer to use to hopefully enhance the sound and had actually settled on a Klipsch only to find out that it had been discontinued when I was ready to place my order. I had seen the Polk Atrium Sub 10 but was initially put off by its shape as I really didn't need a speaker that looked like a plant stand. Plus, the online pictures made it look bigger than it actually is. Long story, short...I settled on this subwoofer, installed PAC BB-150A2 Bass Blockers (at the suggestion of Jeff at Crutchfield) in the satellite speaker + leads, routed it all through a Niles volume control switch and I now have the sound that I had been looking for I am a very satisfied customer and am happy that I went with this product. I gave it only 4 stars because I still think it is kind of a goofy shape but it is stuck back in a corner and is hardly noticed (except for the great bass that it puts out).

Alf from Baltimore, MD on 8/5/2009

Crutchfield Customer Review (What's this?)

This woofer is designed to work with Sat 30 Satellite speakers. I have Atrium 45's. There is no crossover in the Sub. Connections are parallel. This is less than ideal for the Atrium 45's which continue to receive bass signals. Nevertheless, the sound is quite reasonable and very much improved over the Atrium 45's alone.
