Dayton Audio RS180-4 7" Reference Woofer 4 Ohm
Dayton Audio RS180-4 7" Reference Woofer 4 Ohm is rated 4.7143 out of 5 by 35.
Rated 5 out of 5 by from DAYTON AUDIO 7INCH SUBWOOFERI brought 2 of these for my old Yamaha YST-50SW.They work perfectly

Rated 5 out of 5 by from Great woofers!I bought these to mate with my seas 27TAFNC tweeters, and they did the trick!They sounded great and were very easy to work with! Great product from a great manufacturer.

Rated 4 out of 5 by from I am pleased with these.I installed these along with a set of Vifa NE25VTS-04 1" Silk tweeters in my 2002 Oldsmobile Bravada, Crossover duties are handled by an Alpine CDA-9835 Source Unit and they are being powered by a Hifonics HFi 55.4 amp. I have had a few different sets of speakers in my truck (they were all Coax), and this new setup I have installed blows them all away! I have these currently bandpassed at 80hz with a 18db slope and they are being ran up to 1600hz with a 12db slope. After playing with it for a little bit I got these and the tweeters to blend together pretty well.It may be my tune, or my doors not being fully treated, but they do not play low end as loud as I had hoped. Like I said it may be my install. I am still stoked about my purchase, my setup sounds even better than I thought it would. I am a big fan of Dayton Audio now.The woofer feels to be of great build quality, the surround is a little floppy but I assume it was designed that way to play the way it does.In my 02' Bravada I did have to make new baffles out of MDF to mount it. But that was not a big deal.

Rated 3 out of 5 by from Jack of all trades master of none.This speaker has severe cone breakup above 3000hz. This makes it VERY difficult to find a tweeter that plays low enough without distorting.If using a 12db passive crossover I would low pass this woofer at 2000hz. Any higher and during female vocal solo's the cone breakup will be become very noticeable.One of the few tweeters that can run a 2000hz 12db slope passive highpass is the Dayton Reference RS-28. This combined with a 6db Lpad on the tweeters gives excellent sound quality up to moderate volume levels.Running an active crossover with steeper 24db slopes allows the woofer to be low passed at 2500hz without any audible cone breakup. This higher frequency, steeper slope crossover point allows a greater selection of tweeters and allows smaller format tweeters to be used.The build quality and clarity of sound below 1000hz is exceptional.

Rated 5 out of 5 by from Big bass in a small packageI bought these for use in my GTI doors to replace the stock speakers. In my car, the midbass location is less than ideal (speaker fires right into your butt) so I built a 3/4cuft sealed enclosure for each door to move the midbass to the bottom front of the door card.These were run active off of a DEH-80PRS with a bandwidth of 60-3000 htz dirven by a Linear Power 952 at 45 watts per channel.All I can say is in this configuration, in my car, I could get by without a subwoofer and be happy. These speakers love to hammer out the midbass all day long and sound good doing it.I combined these with the RS-28 tweeters run active from 3000 up on a modified Linear Power 452iq at 40 watts and had a great sounding front stage with great depth and width to about a foot outside the A pillar.Really worth looking at these if you like serious up front midbass.

Rated 5 out of 5 by from Name brand killerI like trying from the unknown...Audiomobile, Elemental Designs etc..both from back in the day but were solid performers compared to big name guys. The Reference 7 drops right in my door and the Reference 4 drops right in the dash...no mods needed. The car is a 2012 Sonata and the only processing is from a JBL MS8. So what are these speakers replacing? A $500 Hybrid Audio L3SE set and a $300 Hybrid Audio Imagine 6.5 set. The Reference 7 is so clean and clear its amazing. Combined withe Reference 4 they create such a huge, crisp and powerful front stage with such detail. No lie ...this set up cost nothing compared to what it replaced and was worth every penny. I'm thinkin of replacing my IDQ 10 for the HO Dayton next!!!! Get em!!!!

Dayton Audio RS180-4 7" Reference Woofer 4 Ohm

I am wanting to run two of these in an series and pair them with at Dayton Auidito DC28F-8 1 1/2" Silk Dome Tweeter.  Which pre assembled Dayton crossover would drive this setup correctly.

Asked by: Hempy01
Two of these in series will work well with that tweeter and the crossover below.http://www.parts-express.com/dayton-audio-xo2w-2k-2-way-speaker-crossover-2000-hz--260-140

I was looking at these speakers and I was just curious how would they do off stock headunit power? Just curious I got a Kenwood double din.

Asked by: jdub26
These are 88 db sensitivity and also 4 ohm so they should be fine powered off of a head unit.

How well will this work in the Dayton Audio MTMC-1.0BK 1.0 cu. ft. MTM Curved Speaker Cabinet totally sealed; what would be the lowest achievable frequency (+/-10dB, +/-3dB)?

Asked by: Magnus
One cubic foot will provide an F3 of 67 Hz and F10 of 34 Hz.

In pairing with silk tweeters; what would be the values for making a crossover at 2k?

looking for a nice 2 way component set for car audio
Asked by: tarl01
High and low pass for a textbook LR2 crossover at 2kHz will use the same values, 14uF and 0.47mH.

Is this driver suited to be crossed over at 3000 hz 12db octave?

I'm looking to pair this with the Dayton PT2C-8 Planar Tweeter. The recommended crossover for that is 3000-hz 12db and I'm looking at the pre assembled crossover dayton manufactures for my build. I just want to ensure that 3000-hz isn't pushing the drivers spectrum for clarity and accuracy. Any advice would be grateful, as this is my first two way build.
Asked by: AaronCavalieri
not really,i wouldn't attempt stretching past ~2k.

box and port design

I would want to try a ported box for this speaker used as a mid-bass in the kickpanels of my car. 1cubic foot with 5.3" flared port was recommended. Does it matter if the cylindrical port curves? How about a port 90 degs away from speaker? How about a slot port? How bizarrely shaped can the enclosure be before running into problems?
Asked by: avcinhouston
The enclosure shape and port placement/type will make no difference as long as you acheive the same tuning frequency and have no air restrictions around the back of the driver or the port openings.
