Rated 5 out of 5 by from Worked wellPurchased as a replacement for the sub in my SW-200. A little slight modding to the wiring and it looks and functions better then the stock sub ever did

Rated 5 out of 5 by from Great product!Sounds great, and for a great price. You can't go wrong.

Rated 5 out of 5 by from Tight, accurate, yet low achiever.In the title I mention its tight and accurate. The subwoofer is exactly that, the bass notes are dead on, drum kicks are hit with authority. What really impresses me, is that for an 8 inch woofer, its low end extension and reproduction is unreal. It hits low notes as its 10 inch big brother would. The free air resonance of 31hz is easily achieved and with the right size box and port-tune, its a deadly combo.

Rated 5 out of 5 by from Excellent in vented enclosureI constructed 2 enclosures, a .5 cubic ft. sealed, and a 1 cubic ft.vented (with a 2" by 6" flared port tuned to 34 z). Both sounded great, but I preferred the deeper bass of port. Surprising output for such an inexpensive driver!

Rated 4 out of 5 by from Great replacement, better price.My powered Kenwood subwoofer's foam surround evaporated into oblivian, making this tube useless. Never again will I use any drivers with foam surrounds.The DVC driver almost fit perfectly. This unit has 5 mounting holes and my sub housing and cover has 4. A few new holes in the corresponding areas and Presto!Couldn't ask for anything better.

Rated 5 out of 5 by from Great PerformanceI used this driver to build a small sub to go along with a pair of bookshelf speakers I made. I built a .85cuft box tuned to ~38hz and powered with a Dayton 25W plate amp. Perfect for a small room or computer speaker setup.

Hi, I would like to use this driver with a pair of 8" dayton passive radiators, and a 100watt plate amplifier. What would be the best volume for the enclosure? Thanks. 

Asked by: albertaustralia
I would recommend 1 cubic foot total with 50 grams of weight added to each passive for a tuning frequency of about 30 Hz.

What would be optimum port configuration to use this in the Knock-Down MDF 0.75 cu. ft. Subwoofer Cabinet ?

Asked by: zdog
I would recommend a 2" diameter, 8" long port for a tuning frequency of 32 Hz.

2 -1 configuration for a satellite system.  Bookshelf speakers =8 ohms. This sub can be 8 or 4 ohms.  Since there is no separate volume controls from the plate amp (Dayton SA25 25W), do I need to match impedance between the speakers?

Asked by: TandEsdoorman
In order to use this and the SA25 with two small satellite speakers, you will need another small amplifier to power the satellites. I would recommend wiring the sub coils in parallel for a 4 ohm load to the SA25 and use the speaker level inputs and outputs with a small 2 channel stereo amp to power the satellites.

I want to use this to replace dead subs in a polk RT20P tower speaker, running series. Think these will fit in the holes?

Asked by: AlphaPie
Unfortunately we have no way of knowing. The cutout dimensions for this woofer are on the product page, you will have to pull the original woofer out and compare the diameters of the holes in your cabinet.

What size amp would i want to run with this for a car audio application?

Asked by: AmpLess
Anything around 100 watts RMS at 4 ohms will be ideal for this woofer.

Yamaha SW-P201 started popping with loud scenes (clipping?). Will this woofer eliminate this? Original driver 6.5" 6ohm 25W (JA1678). Amp output 50W/5. Power consump 42W.

Asked by: Rick71
The popping is probably the woofer bottoming out due to over excursion. Without knowing the enclosure volume and tuning, or the Xmax of the original driver I cannot say how this will compare.
