Dayton Audio RS180-8 7" Reference Woofer is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from Super Bassder rs 180-8 ist einer besten Basslautsprecher für kleine Boxen den ich kenne. Kann ihn nur weiterempfehlen.the rs 180-8 is a best bass speaker for small speakers I know. Can only recommend it

Rated 5 out of 5 by from ExcellentI'm pretty sure that it's not possible to get a better woofer at this price. Distortion is amazingly low. Build quality is excellent. Appearance is nice. They take punishment well. Only two slight problems: one is that air can pass through the annulus around the phase plug and be a bit noisy with loud deep bass in a sealed box. The second is that under some conditions of extreme excursion, the woofer center position can be lost, where the motor will develop a position offset, thus limiting effective excursion under those conditions.

Rated 5 out of 5 by from Outstanding midwooferUsing this in a smallish 2 way tower. The crystal clear clarity must be heard to be believed. Doesn't hurt that this driver looks darn good too, good enough that leaving the grilles off is a definite option.But you will absolutely require a notch filter in the 9KHz region unless you are are using a 4th order low pass xover on it.In my case, I built a 9KHz 15db notch filter, and am crossing over at 2KHz with PE's 2KHZ 2nd order Linkwitz-Riley xover. This removes the peak more than enough so it isn't audible at any level I play the speaker system at up to it's power limit.

Rated 5 out of 5 by from Little 7 that could.I bought a pair of these little se7en RS180-8 speakers for a three way bookshelf replacement project. I used Wins Beta to tune the port. The .42 ft^ box was tuned with a 1 3/8 diameter port at 5 1/2 inches long. I used the HiVi DMN-A soft dome midrange from Parts Express. The 6dB crossover's were set at 700Hz and 10,000Hz for the small silk some tweeters. These two bookshelf speakers are excelling as the center channel in my 7.1. They are very smooth and drive the lower base down to 60Hz (subwoofer crossover) without any distortion at 50watts RMS. THESE ARE EXCELLENT SPEAKERS. I would recommend any of these RS speakers.

Rated 5 out of 5 by from Very good quality wooferBuild quality of this woofer is excellent, especially considering the price. Low frequency performance is excellent in a reasonably-sized vented box as well. These perform nicely down to around 40Hz. Specs measure very close to those advertised. As with any aluminum cone driver, there is a breakup that must be dealt with. This means special attention to the crossover. There are several good crossover designs on the net. Make sure to check them out before you buy. You will also need a tweeter that can handle a relatively low crossover point in order to keep the woofer out of the breakup region.

Rated 5 out of 5 by from Fantastic soundI have two of these coupled to a 2800hz 24db crossover with a RS28F-4 tweeter(WTW) and let me tell you the sound is phenomenal. Im using an adcom GFA-5400 and GFP-555 and the sound is really accurate. I have been playing everything from "The Orb" to "Eric Clapton" to "Beethoven". Right now I am pushing 200 watts in to the setup and it is loving it. I am impressed that PE is able to sell this at such a low price with such a high value.

Dayton Audio RS180-8 7" Reference Woofer

I was wondering how well these would perform in a 0.56 cubic feet cabinet that is ported? If so, what diameter and length port is best for this application?

Asked by: bteklits
This will work well in that volume. I would recommend a 2" diameter, 6-3/4" long port for a tuning frequency of 43 Hz.

I wanted to build a sealed box design with this woofer paired with the PT2C-8 planar tweeter. question is what size box should I build?  and what would the correct crossover frequency be for these two drivers to match well?

Asked by: mvintage
The sealed box for this woofer is pretty small at about 0.16 cubic feet, which will only get you to about 90 Hz or so. If you want any bottom end from these I would recommend vented in about 0.5 cubic feet tuned around 50 Hz. A good crossover would be 3kHz second order.

What would be the correct sealed enclosure volume for this driver?

I am going to build a set of boxes to hang on my porch. I was thinking about a MTM design, I was wondering if it would be better to have one chamber for each driver or both drivers share a chamber? I am going to use DC28F-8 tweeters.
Asked by: brucealmighty
I would recommend .3-.4 cubic feet per woofer. This will provide an in-room response into the low 40's. You do not need separate chambers for each woofer although cabinet bracing is recommended.

What volume would this take up in the box?

Asked by: johnnadskb
I assume what volume do you add to the box to compensate for driver displacement. Fogiving the thickness of the baffle - your major concern is the size of the magnet. For the sake of conservatism, assume 2" thick x 7" diameter. Using PiR2 (Pi R Squared) - you can figure an approximation that is adequate for anything outside of laboratory measurement. For more accurate numbers - measure an actual driver, or buy a "spare" as we call in design - a "Sacrificial driver" that is broken and used for routing. In this case - you would dip it in water to see how much volume was displaced - which would be the most accurate.

For Celestion 5?

Would these be a good replacement for damaged Celestion 5 woofers? The size is about right.
Asked by: Igor
It's a great driver - check the T/S parameters with a box calculator to see if the box volume is close - or look at speaker building, woofer selection guide on this site

Are these drop in replacements if you need to replace the woofer in a design that uses the previous Rs180-8 shielded?

One of my woofers went bad and I need to know if I have to seek out a shielded rs180 or not. Will crossover mods be necessary?
Asked by: Tyroneshoes
The unshielded Reference Series drivers are designed to be drop-in replacements for the shielded Reference Series drivers. No crossover adjustments should be needed.
