Dayton Audio PS220-8 8" Point Source Full-Range Neo Driver

The Dayton Audio PS Series drivers do it all: true bass, articulate midrange, and balanced, extended highs. An intensive program of design and testing has yielded full-range speakers that feature high sensitivity and smooth response, both on- and off-axis. Although an ideal match for lower powered Class A and Class T designs, the PS220-8 8" driver's superb resolution and natural sound quality make it a viable option for an even wider variety of applications. The PS Series' audio performance is complemented by the speaker's striking appearance—they look great in dipole and other open back designs, too!

Dayton Audio PS220-8 8" Point Source Full-Range Neo Driver
Dayton Audio PS220-8 8" Point Source Full-Range Neo Driver is rated 4.5385 out of 5 by 13.
Rated 5 out of 5 by from THE sound I've been looking for!My last purchase was the Tri Trix set and that was my favorite so far. However as a perfectionist I found too much conflicting info on the effect of crossovers on purity. So this time I aimed for single point source sound. I built a set of TQWT cabinets that I actually had seen in a dream of mine which I couldn't afford to patent so I made them public for all. The unique design is from the completely curved base, ballasted by 80 lbs of sand to stay upright like a weeble, this way the speakers can be tilted to the listener. The specs; 2.76 cu ft, line length 81", throat 0", mouth 114 sq in. Overall size 48" tall, 15.5" wide, 11.25" deep.The sound? Clear. Immersive. Detailed and deep. Tuned to appx 42 hz there's no need for any assistance high or low. I don't need a video screen to know where the perofrmers are. These speakers are epic in value. Stop reading and just buy them already!

Rated 5 out of 5 by from point source speakersI've been a speaker fanatic, mostly building them, for 50 years.My main speakers use lowthers in Oris horns. I have a small system in my study using these PS220-8, very simple, using a subwoofer. It sounds just great, excellent definition, imaging and dynamics. so I bought another set to make a system for a newly married son. I measure performance by ear, not instrument.

Rated 5 out of 5 by from PS220-8I really like this driver. I have tried more than a dozen drivers, for both multi-way speakers and single driver, and this is my favorite so far. It mates well with the Lepai 2020 which is a bonus, since it's cheap, and doesn't heat up the room or draw much power. It didn't mate as well with my tube amp, so now I'm using the Lepai. I have it mounted in a transmission line. It sounds so alive.

Rated 5 out of 5 by from Excellent DriverUsed this driver to replace the woofer in my old Bose 301 cabinets. I have had the Bose 301s for a long time over 20 years, decided to replace the woofers with the Dayton Audio PS220-8 8" Point Source Full-Range Neo Driver. I also used the back firing tweeter but used a Dayton PMPC-1.0 1.0uF 250V Precision Audio Capacitor for the crossover. These speakers are power by a Psvane Kt88 set tube amp and the bass is handed by a Dayton 12 inch sub powered by a Dayton 250 watt sub amp. I also built the cabinets for this sub, looks like an end table. Changing to these full range drivers was a move I should of done years ago. I highly recommend using these drivers as a replacement for anybody using set amps and listen to acoustic music over the electronic. I have used Parts Express for other projects and can say their products are excellent in the correct application.

Rated 5 out of 5 by from Much better than expectedJust received these drivers and installed them in home built enclosures from a previous Dynaudio project built many years ago. As it worked out the Dynaudio woofers were just pulled from the market so I substituted Scanspeak 8" woofers in a 1.24 cu. ft. ported enclosure tuned to 38hz.The Dayton PS-220's dropped right in right down to perfect screw hole alignment. I just bypassed the x-over.In this set-up imaging is outstanding and the base nearly equals the Scanspeaks. Speaker placement is crucial for a realistic sound stage and I have achieved this.The ultimate goal if to built the 84" t-line enclosures tuned to 40hz. I am researching the options for this now.These speakers are awesome with all the highs you could ever want, in fact I plan to build a 0-6 db variable roll-off network tuned to 480hz(based on enclosure width) that will install between the preamp and power amp.

Rated 5 out of 5 by from Horn Loaded PS-220Originally I purchased this driver for a FR project, however I decided to go a different route and build a Tractrix waveguilde for it instead. This driver in a sealed box has a rising response.Once I loaded it into my waveguide, the response was very stable 200hz and up. This is a fantastic sounding driver, I use it bandpass from 375-3000hz.

What's the best enclosure for these speakers?

Would a ported design work better here?
Asked by: Kasboot
If you want to hear these speakers really perform, build some quarter wave cabinets. use 40 HZ lines about 84 inches. You won't be disappointed...

i have a pair of welborne labs moondog 2a3 single-ended triode amps that put out a maximum of 3 watts each. is this enough to drive these speakers?

Asked by: modernspeakers
The sensitivity for this driver is rated rather high at 95.5 dB @ 1W/1m, so your amplifier should be able to drive this just fine.

is this driver optimal for an open baffle system?

Asked by: modernspeakers
No. Its Q is too low, its Xmax too short and it is too small a diameter anyway.

Has anyone tried this unit in a backloaded horn?

Asked by: oddioguy
I have these in a pair of backloaded horns designed for the Fostex FE208E Sigma drivers.I haven't used these cabs with the Fostex drivers but they sound pretty awesome with the daytons in them.Nice lows with clear mids and sparkly highs.The stereo imaging is freaky (good). Had to do some tweeking with the eq but that's pretty normal.Here is a link to the cabs I built for them. I know the specs aren't perfect but they do sound good.http://www.parts-express.com/pedocs/more-info/295-346-dayton-audio-ps220-8-more-info.pdf

What is the best frequency to tune to?

I have been doing a lot of research on this speaker as well as the Tang Bang Point source speaker and was going to try a more advanced box design such as a transmission line or horn design but don't have the needed space to work with so I think I will have to settle with a standard Bandpass box. My question is: What is the ideal frequency to tune the box to, and what roll off frequency should I aim for? Or is this 100% based on my room size and my 12" dayton T1203 Sub?I did the math and found the following but do not know which to choose (or if these are 100% accurate but they seem right):.875 ft^32-1/16" port @ 3" long(tuned to 48 hz - Roll off ~ 71hz).5 ft^32-1/16" port @ 5" long(tuned to 52 hz - Roll off ~ 77 hz).387 ft^32-1/16" port @ 5" long(tuned to 60 hz - Roll off ~ 89 hz).25 ft^32-1/16" port @ 5" long(tuned to 74 hz - Roll off ~ 110 hz)Any help would be greatly appreciated.
Asked by: Philip
I'm guessing that your system has a variable low pass filter for the sub while the stereo speakers run full range. I would suggest a sealed box of about .4 cubic feet for your stereo speakers to keep out the low bass notes. The sub would take over below 90-100 hz. Doing it this way will give you the clearest mids and highs.

Vol. needed for 2 in a single stuffed b-r box (stereo) and amt. stuffing?

Can be a fairly large box, to sit on free standing shelves above and slightly behind the laptop desk.
Asked by: 2tune
Depends on how much low frequency extension you want. This driver does very well in large boxes. One cubic foot per driver will give you flat response to around 60 Hz if tuned properly. Larger boxes will give more extension. Be sure to separate the box with a divider for left & right sides.
