Product Details

Dayton Audio DC250-8 10" Classic Woofer

Dayton Audio Classic Series woofers are excellent for use as replacement speakers or for new loudspeaker system design and construction. The DC250-8 10" woofer has developed quite a reputation for having the best bang-for-the-buck performance and value available anywhere. Smooth frequency response and extended bass performance make this driver ideal for use in large format two-way and classic three-way loudspeaker designs. A Qts of 0.45 allows the DC300-8 to work well in both sealed and ported speaker enclosures.

A non-pressed treated paper cone allows for smooth frequency response, while the high temperature aluminum voice coil and vented pole piece combine to increase power handling without compression. Longevity is ensured with the use of a rubber surround, treated cloth dust cap, and an extended bump plate.

Rated 5 out of 5 by from Perfect replacment for Bose 501 Series IVTotal replacement time including removal, soldering wires to the new speaker and screwing it in was less than 10 minutes.

Put this new complete speaker in and make the house move with live active music! You will not go wrong and will be very very HAPPY! My "1984" 501 Series IV's came alive again!!!!

Rated 5 out of 5 by from Just What I NeededThese were replacements for some woofers purchased from Parts Express about 20 years ago....these are my shop speakers, and experience welding flash, cold, and heat....one of the old ones tore a foam surround. Enter these....they sound great! Good for another 20 years of rocking my shop.

Dayton Audio DC250-8 10" Classic Woofer

use for floorstanding 2 way w/out crossover-need cabinet size/volume

going to run this woofer full range with a GRS piezo tweeter in a pair of floorstanding speakers for my home theater setup. ported or sealed? hoping to avoid buying a subwoofer and tune these pretty low. what is a good range for the cabinet volume? i would like to keep it under 1.75 cubic feet. thanks!
Asked by: Dave B
Dave; I have two that I installed in JBL L36 bookshelf speakers to replace the original 125A woofer. These cabinets are about 1.54 cubic feet in internal volume. I ran a frequency response and got good bass response down to 35Hz and some gradual drop-off under that. The useable response extended to about 22Hz. The L36 is a ported enclosure. The free space resonance is around 28Hz so this one works well for most situations either ported or sealed. The sealed box bass may drop off more rapidly than you might like. Most instructions say shoot for a .7 Qtc (speaker installed in cabinet). Research the Thiele-Small measurements and recommendations for speaker building for best explanation.

What is the best crossover frequency for this driver for a 3 way design?

Asked by: Speakergeek52
It all depends, you want to try and match a point that is also good for your mid. In general I would say a 700-1200hz crossover should work with most mids. The lower the better as long as your mid is capable of a lower crossover point.

Enclosure type and size range.

Similar question to the first one, what type and size of enclosure will these work best in for music with a reasonable F3, ~32hz-ish? My plan is to use two per enclosure.
Asked by: MetricMuscle
I would recommend a sealed box of 1 cu ft per sub. You can play around with it as they seem to be pretty flexible. 1 cu ft seems to keep the power handling up and provides a smooth response. They will work in ported as well but not unlike raising the air space in a sealed box the power handling drops off pretty quickly.

I have a pair of Boston HD8 speakers, their cones have disintegrated and I am thinking of using Dayton Audio DC250-810" Classic Woofe as Replacement

Do you think this is a good match or should I use a different type. I am using a DENON PMA-360 amp
Asked by: Dudley
The amp doesn't matter - what does matter is whether the DC250 is a match for the older Boston's. First, you can always have the speakers reconed. There are many shops that do this. Second - if you want to replace - the new woofer needs to match the box (use the specs and confirm with a box calculator), have the same impedance as the current woofer, and the same efficiency rating... If those are the case - then you have a drop in replacement. If not, you may not have deep bass, or it will be out of balance with your tweeter.

Will a pair of these replace a pair of Bose 10" woofers in a pair of Bose 501 series III OK?

Asked by: moparrog
See 5 out of 5 Engineer rebuilds Bose 501 review above. Some one had the exact issue you have and was succesful. "This speaker is a great drop-in replacement for the Bose 501 Series IV woofers (Bose part # 111791). The Series IV 501s have a 2.0 cubic foot ported box with 5" long 3" diameter port (fb = 36 Hz). I simulated with many replacement drivers and this one is a great match, providing an f3 of 37 Hz with a few dB of peaking at 55 Hz. The bass is actually superior to the original drivers, which were somewhat underdamped."

1.7 cf Realistic Mach 10 Box ?

How well would this woofer work in a 1.7 cf box ? And if better with a port, can anyone suggest a good setup ? Thanks
Asked by: poundasound
This works very well in that sized enclosure, without a port. As for port size and configuration, there are a number of nomograms available on the Web for working that out.
