Dayton Audio ST255-8 10" Series II Woofer
Dayton Audio ST255-8 10" Series II Woofer is rated 4.3611 out of 5 by 36.
Rated 5 out of 5 by from Initial Review....This woofer is great, breaking it in and also replacing some other speakers in my vehicle. Put it in roughly a .5 ft^3 box (.44 ft^3 sans woofer displacement), 'hermetically' sealed and lightly damped on 5 inside panels, but not the baffle; .5" PSA dampening material used. Throwing right at the indicated specs for power usage, RMS & Peak. Throws out some great bass, with good impact for merely one 10" woofer, and it also hits the lows well and it's not even close to fully acclimated to the box and power usage, etc. I do highly recommend this speaker (per application and desire, though, and it) has decent sensitivity, isn't overly mass loaded and within the optimal power range of the amp I'm using, along with the load it provides. RMS output is about 115dB and peak is somewhat higher with the config I'm using. Also, 150Hz down, electronically, is how I'm going with its crossover point, as I like some beefy bass guitar tuneage, as well as many other varieties of music, which this woof/sub is doing well with.Regards!

Rated 5 out of 5 by from Replacements for Electro-Voice Sentry VI've been carting around a pair of old studio monitors for years. Originally purchased around 1977. The woofers were shot and these fine units spent 25 years in the basement. I home built an entire home theater system from Parts Express products 10 years ago and was thrilled to see they're still around. These woofers are perfect replacements for the EV Sentry V. They fit perfectly and although the originals had only 4 mounting holes these lined up precisely. The connection tabs were slightly larger than the original EV drivers and I opted for direct solder. The sound is unbelievable. This is a vented design and is efficient, these woofers match very well. Could not be more impressed. Build and packaging appears to be top notch. The entire purchasing experience was first class.

Rated 5 out of 5 by from Very HappyMy wife brought some Bose 501 speakers home from a garage sale because she liked the grill covers. They will fit in with our retro MCM style, so that is the only way i can get speakers in the house. One woofer was missing and the other's surround was falling apart. The 501's and the Bose line in general doesn't get much credibility in the audiophile world, so I took the opportunity to upgrade the main woofer with these. The cabinets seem sturdy enough to warrant keeping. I tried the Dayton Audio designer series first, but they were a tiny bit to big in diameter to fit in the cabinet, which was too bad since the range on those looked like a good fit with the crossover's in the 501's. So Part Express was great about letting me return those and I went with a more expensive speaker (Series II) and double checked the measurements. These dropped in fine and the magnet is huge and heavy. I have no idea what 501's sounded like originally, but mine sound nice and are going to be awesome for any party because the bass really sounds nice and rich and tight at high volume. BTW the "direct energy control" function of the 501's, really work. I thought it was just a gimmick.

Rated 5 out of 5 by from Nice sounding Woofers!I had purchased 4 of these Dayton 10" Woofers and 3 of them arrived with the same assembley defect. However Parts Express was outstanding in their customer service and replaced them very quickly. I figure it was just something that happened during part of this production run, as they are highly regarded Woofers.This is a great place to do business!

Rated 4 out of 5 by from Very good replacement woofer for EV Interface C (s4)Used as a replacement woofer in my 1983 Electro Voice Interface C (series 4) speakers. I am pleased with the speaker performance. The EVs now sound great. The only downside is the external speaker surface coating is a bit sticky.

Dayton Audio ST255-8 10" Series II Woofer

Using this woofer in a 1.35 cu.ft. enclosure, x-over at 2.5K, what is the optimum port size? There is currently a 2" diam. x 4" long port. Can I modify this port and/or add another port?

Asked by: mcm62
I would recommend adding a second 2" diameter, 4" long port to this enclosure. It will help reduce port noise and bring the tuning frequency up to a more reasonable frequency of 40 Hz.

I hava a bash 300s 300 watts  and this woofer works for my amp?? Becase i needa home woofer

Asked by: el chupa cabras
Yes this woofer will work with that amplifier but it will only produce about half of its rated power due to an 8 ohm load. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.

I am looking at this driver to handle mid bass duty in a sealed 1 ft3 sealed enclosure. Need a flat response from 80-250hz. Is this a good option? Need high Qms. One of your comments this driver is not a good candidate for a sealed enclosure.

Asked by: Aleph30000
This will work fine in that range. Its not recommended for anything below about 60 Hz in a sealed enclosure, but from 80 and up you won't have any issues.

Will this woofer work well in a sealed enclousure?   Im looking for a woofer replacement for my sealed  home tower speaker cabinet..,,   If not can you guys help me make the proper port for my cabinet in order to use this woofer?  Thanks

Asked by: blue horse
This woofer will have very limited low end in a sealed enclosure and would work best ported. We will need to know the volume or dimensions of the cabinet in order to help with a proper port size.
