Dayton Audio RS180-4 7" Reference Woofer 4 Ohm
Dayton Audio RS180-4 7" Reference Woofer 4 Ohm is rated 4.697 out of 5 by 33.
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!!!!

Rated 5 out of 5 by from Best midrange/midbass I've ever owned!I've been a professional car stereo installer for 21 years now so I've seen and done it all. I purchased a pair of these Dayton Audio 7" Reference Mids along with a pair of the Dayton Audio Reference silk dome tweeters. I used a pair of Boston Acoustics passive colrossovers that we had laying around the shop and powered this set up with a JL Audio HD 600/4 amplifier. I have the 7" Mids in custom kick panels and the tweeters in custom pods at the top of my dash. These Dayton Regerence speakers are truly amazing. The sound is crystal clear at all times, high volume or low volume. I can confidently say that these Dayton speakers sound BETTER than the JL Audio C5 and ZR series components that we install everyday! The silk dome tweeters are so smooth and natural sounding. The Mids are loud without being harsh on the ears and deliver terrific midbass and punch. Whether you are an audiophile or a bass/techno head you will be blown away with the quality and price of the Reference series. I'm now a Dayton fan for life!

Rated 4 out of 5 by from Mixed review, didn't work with my applicationThese speakers went into my 2006 Dodge Magnum with heavily treated doors. Paired with Vifa XT25TG30s (2.5 khz/18db)in a 3-way active setup off two Audison srx2s amps sourced from an Alpine iDA-x305s with an external imprint processor. Substage consists of 4 RE SE 12s (80 hz/24 db) on a Crescendo bc3500.These speakers, whilst sounding amazingly clean and having a tight punchy midbass, simply do not put out like I guess I was expecting them to. They quickly hit a ceiling and would bottom out, even crossed over at 80 hz/24db . I had to drop the tweeters -7db just to get the sound to blend and image correctly and the tweeters still seem overbearing regardless of my crossover on them.I really do like the way these sound but for my application, (single woofer) they simply can't do the job and I'm swapping them out for a more efficient, Crescendo PWX6.On a good note, these woofers are built very and I will DEFINITELY be making a pair of WMTM towers using these and seeing their true potential in a more well-suited environment.

spl rating is 91 db on this page but one DA spec sheet its 88?

Asked by: FrankiE
The "normal" (traditional) rating of SPL is at 1w@1meter. According to that rating system, this speaker will deliver 88db SPL (sound pressure level) with a 1 watt input measured at a distance of one meter. The sensitivity of the speaker can thus be compared honestly to that of any other speaker that is rated using the "1w@1meter" method. The "higher" rating you see, 91db, is not an indicator of a louder speaker or of a publishing mistake. The 91 db is the SPL rating using an alternate measurement method using a specific VOLTAGE at the input instead of a specific WATTAGE.The volt rating can be compared honestly to the SPL of any other speaker that uses the 3.83 volt input measure rather than the 1 watt input method. The 3.83 volt measure is more flattering for lower ohmage speakers.When a potential buyer is comparing the SPL of this speaker to that of a different speaker, publishing both figures gives you the ability to compare the two speakers using whichever method the other manufacturer publishes.Publishing both figures is an indicator that the manufacturer is trying to be honest and give the maximum useful information for comparison. It can also be confusing, but that is not the intent.

the advertised price is for one pair, or is it just one speaker?

the advertised price is for one pair, or is it just one speaker? I wonder also if there are speaker grilles that meet this measure 7 ".thanksManuel
Asked by: apercu
The price if for one speaker, 6.5 and 8" grilles are available, you could always use grille cloth.

Will this fit in my 6 1/2" opening in my 03 civic?

Asked by: Randy R.
No, these will not be a simple drop in but with a little modification you should be able to get them to fit properly.

what is best size enclosure for a sealed alignement??

Asked by: randyc1
Recommended sealed enclosure is 0.6 cubic feet which will provide an F3 of about 65 Hz and an F10 of 38Hz.

I was wondering if these woofers would be a good match to the Vifa NE19VTS-04 3/4" Silk Dome Tweeter crossed over at say 2khz 12/dB?

I hope im making sense because that tweeter has the right dimensions to fit my a-pillar.
Asked by: fatboy
They are a good match. I would think that a somewhat lower crossover point (1800) might cross the woofer in a more linear range, but what you propose is within the specs of both drivers.
