Dayton Audio DA175-8 7" Aluminum Cone Woofer
Dayton Audio DA175-8 7" Aluminum Cone Woofer is rated 4.5882 out of 5 by 34.
Rated 5 out of 5 by from Great speaker for a great price!I bought a pair of these to refurbish an old Yamaha YST-SW120 subwoofer. They have made it sound better than when it was new! I mostly listen to jazz and instrumental music with a lot of double bass and it is amazing how much better it sounds! I have it paired with some M-Audio AV40 studio monitors and the combination is excellent for near field listening! I have the subwoofer crossed over at its highest level- 140Hz so the DA175-8s take over some of the woofer duty as well. Perfect fit and great sound! Also excellent for movies. Thanks!!!

Rated 5 out of 5 by from Great Value!I bought this to replace the speaker in my Klipsch 2.1 sub-woofer. The Dayton DA175-8 7" fit right in the woofer box hole. The only modification was to redrill for 5 holes for the new woofer and put a new larger quick connector for the ground to fit the speaker. Due to the slightly different design of this speaker the grill will not fit back on the enclosure without some modification. The sub-woofer looks great without the grill so I'm leaving it that way.

Rated 5 out of 5 by from More Zaph BAMTMsLike several other reviewers I used these to build a pair of Zaph Audio's "Bargain Aluminum MTMs." They're crossed to Seas 27TBFCG tweeters and paired with DIY sealed stereo subs using Dayton's RSS315HF 12" drivers. They are as clean and accurate as any spealers I've ever heard. See the nearfield FR/THD plot using REW (MTM only, sub not included).

Rated 5 out of 5 by from Great WooferI built a pair of Schumakubin MKIIs recently, and these are spectacular as a woofer and as a mid. Paired with a Dayton RS28F this is what a speaker is supposed to sound like as far as I'm concerned. Very correct and lots of output.

Rated 5 out of 5 by from Klipsch PC 2.1 and 5.1 woffer repacementBlew my Klipsch 2.1 and 5.1 woofers out. 2.2 has 1 woofer, 5.1 has 2. Dayton DA175-7 7" fit right in the woofer box holes. The only modification was to redrill for 5 holes for the new woofers and put a one new larger quick connector for the ground to fit the speaker. Very simple. Also bend the screens out with pliers to snap into the woof box. 10 minutes done. Sounds much better than ever. and saved hundreds.

Rated 5 out of 5 by from Amazing sound quality!First off, I give a solid 10/10 when you factor in value, price, and extremely high sound quality. I bought four of these for a pair of speakers I was building (2 per speaker cabinet) and now that it's all done, let me just say, these are your speakers. tight bass, clear mids, and good, clean highs (these go up to about 10,000 Hz). Paired with a 2" paper cone tweeter and a 4,500 Hz crossover, your woofer shopping stops here.

Dayton Audio DA175-8 7" Aluminum Cone Woofer

I have 2 of these and would like to use them for a subwfr application (<30hz desired). ~100 wpc amp 1) How do I determine the best box size/port dimensions/tuning etc? 2) cani use both of them in one enclosure working together? or do 2 separate subs?

Asked by: stevebu
Two separate subs are almost always better than one, but it really is application specific. These are able to be tuned relatively low, but will be limited with overall output capability. I would recommend a volume of 1.25 cubic feet per woofer, with a 2" diameter, 6" long port for a tuning frequency of 29 Hz and F3 of 26 Hz. Keep an eye on woofer excursion, these wont take much more than about 20 watts without having problems.

I am considering using a pair of these to replace two 7" drivers in a Yamaha subwoofer model YST-SW120. Crossover adjustable up to 140Hz. The cabinet is 1.6 cu ft. Port is 10" long with 3" diameter. Workable? Suggestions? Thanks!

Asked by: Colorado_al
These will work quite well in that application. It looks like your tuning frequency would be 30 Hz.

I'm considering using this driver as a woofer in a three way setup, but when I model it in winisd with a 2 cubic foot vented box tuned to 26hz it shows that the woofer will exceed Xmax with only 10 watts or less. What can I do about this?

Asked by: TadCat
This is a sign that you are probably trying to use an enclosure volume that is too large, or a tuning frequency that is too low. With most woofers, I highly recommend tuning the cabinet as close as possible to the driver's Fs frequency, then adjusting the cabinet size as needed to obtain the flattest response. If you have a driver with high Qts (greater than 0.7), you can often use a larger cabinet and tune below Fs to gain deeper bass, but if the driver is in the typical 0.3 to 0.5 range then this strategy more often results in over-excursion with little input power, just as your simulation is predicting.

Can this woofer be used in car applications? is there a 4ohn version? if so can it be used in a rear deck no enclosure?? Trunk space roughly 12cu/ft

Asked by: djchino69
Unfortunately this is only available in 8 ohm but it can be used in a free-air automotive application.

Can you use this woofer for a cheap studio monitor/ even though the efficacy is a little bit low? Not going to play them that loud. near field listing. 

Asked by: hugga77
Yes these can be used for a nearfield monitor application.

The cone feels crunchy and the sound is crazy overdriven.

I finally got this guy set-up in a (very) small fiberglass box and have it crossed over below 800 hz, but whenever I start to move the volume into ranges above normal bookshelf level, it immediately starts chattering and sounds extremely overdriven. I don't know enough to diagnose the issue, but when I press on the cone there's uneven, crunchy resistance.However, I also have it set up in a very small box that has yet to be 100% sealed, and the speaker does not bolt into it yet. Is it possible just that minor seal issue is causing my problem?
Asked by: Bad Sushi
Pressing on the cone of a woofer is not a very good way to test for problems. If the woofer is being driven beyond its limits this is likely a combination of a box that is not sufficiently sealed and simple woofer distortion at high volume levels.
