Dayton Audio RS270-8 10" Reference Woofer
Dayton Audio RS270-8 10" Reference Woofer is rated 4.6667 out of 5 by 3.
Rated 5 out of 5 by from I love this woofer.My music source is a laptop dedicated to Windows Media. From this, a Topping TP60 amp drives a pair of TMWW’s, each of which has a B&G Neo3pdr tweeter, a Dayton Rs52 midrange, and two Dayton Rs180 woofers. To me, this sounds very nice. But to also "make my feet move" by warming the room with lower bass, and to accentuate the kick drum, I added a “hi-fi woofer”. This is a Dayton Rs270 woofer in a 3.25 cubic foot box with an 8-inch-long 3-inch Precision Port, driven in mono mode by a Dayton APA150 amp. (I also have a low-pass filter, part 266-446, between the APA150 and the woofer.) This does just what I had hoped, adding the low bass and kick drum in what I think is a very musical manner that, to me, enhances the presence and warmth of the music delightfully.

Rated 4 out of 5 by from Hefty woofer for sealed enclosure and low xoverThis woofer has potential for medium speaker enclosures. It's probably best used in sealed applications with very carefully designed crossovers around 1.5khz. I don't think this would sound well at higher points.I tested this in a large bookshelf speaker and ran into two problems. First, the woofer required a zobel element to smooth out the crossover point, and secondly, my enclosure couldn't support the frame's weight.This is an impressive woofer that offers lots of possibilities if you have a larger, sealed enclosure and crossover point.

Rated 5 out of 5 by from Beautiful speakerThe RS270-8 is a well built unit with performance that belies it's reasonable cost. Used as a woofer in a 3 way system or mid-bass in a 2 way it hold up the low end nicely. Probably not a good choice for a sub woofer, but that doesn't seem to be the design goal. On top of it all, it's absolutely sexy with the large phase plug thrusting up from the center.

One of these in a 3 cubic foot sealed box? Doable? Would be using up to about 1500kh. Or ported?

Asked by: Disease
A sealed box would be a .53 qtc which is not necessarily a problem, just a little larger than normal. Porting will provide a little lower F3. Either one would be suitable for this application though.

How will this speaker work in a 1.25cf cabinet with a 2000hz crossover to tweeter?

Asked by: john88
This woofer will work well in that volume sealed. It will also work well with that crossover point.

Hello, would this driver perform well using a Dayton XO3W-375/3K crossover in a 1 cubic foot sealed chamber of speaker enclosure?

Asked by: Vunce
Yes this would work fine as a woofer in that volume with that crossover.

I have 4 of these from a previous project now sitting in a drawer.   Would these do well in a sealed 4x10 cabinet for bass guitar?  My 1x12 Basslite does not have great enough clarity in the fundamentals.

Asked by: 11Bravo
Bass guitar speakers have a very wide frequency range, and are also high in sensitivity (so they produce the maximum SPL possible for the amount of power input). These drivers may work as a "subwoofer" or low-frequency only cabinet in addition to your existing cabinet, but I don't know if they would have enough top end for your needs, and their sensitivity is lower than the type of musical-instrument 10" drivers commonly used in bass guitar amplifiers, so they will need more power to push them to the same output levels. The sensitivity of a 4x10 cabinet with drivers wired series-parallel for an 8-ohm load would be about 90dB 1W/1m.
