Review: Perfect fit for Basscube 15 - I bought this as a replacement for the amplifier in my Cambridge Soundworks Basscube 15 on a suspicion it might fit based on the measurements. I was very pleasantly surprised that it not only fit, it was an exact fit - same screw holes, same cutout size, same lugs for the speaker, same sealed box to protect it. Seems like the same amp, but updated. Performs flawlessly, at least initially, and restored the sound and eliminated the horrible hum I had.
Review: Couldn't be happier! - Well....bought this to replace the amp in my Cambridge Soundworks 12" subwoofer. The original amp never seemed to work properly, and finally died about 3 years ago. Since then I'd been using an old stereo receiver to power the subwoofer. Any way, this Dayton subwoofer amp has exactly the same dimensions as the original amp - including the mounting screw locations! That was admittedly pure luck, but boy, was installation easy! And so far, it's performed flawlessly. It even seems to sound better than the original. It does have more power, so I'm not too surprised about that. It arrived pretty quickly after I ordered it, so I'm one happy camper! I'd definitely recommend this amp to someone looking for a replacement subwoofer plate amp - even if you have to do some trimming to fit your subwoofer enclosure.

## Questions & Answers

**Q: What are the dimensions, trying to replace amp on a klipsch rpw10**
A: The specs are on the Dayton Audio website.  The SPA-250 page is here:http://www.daytonaudio.com/index.php/spa250-250-watt-subwoofer-amplifier.htmlOverall dimensions are listed in the spec table near the bottom of the page.  Cutout dimensions are in the last paragraph of the text portion of that page.  The cutout dimensions should be 8.5" x 8.5".  Be aware that the amplifier unit is 5" deep, and may require trimming of the internal baffles of a subwoofer cabinet.

**Q: Is this amp stable down to 2 ohms?**
A: probably not

**Q: Can I power a driver in the front and shakers from the back using the high level outputs at the same time? The bass shakers are two ohm buttkicker min**
A: The outputs are a by-pass of the inputs. The idea of this amp is to send full frequency audio (20 -20kHz) in and full audio out. The plate amp strips off low frequencies (below 200 Hz) for a subwoofer or shakers. So assuming full spectrum audio in, you would not want shakers on the high outputs. If you did this, the shakers would be shaking most of the time which would be very annoying. As far as impedance, you must normally keep the load between 4 and 8 ohms. (This depends on the amplifier’s design.) So if you have 2 ohm shakers, you would connect 2 in series to get 4 ohms. (Ohms law).

**Q: Low frequency ranges. Will it do 32hz**
A: It should do 32Hz quite well. With a test cd, mine had no problem at 16Hz although the subwoofer was moving air but difficult to hear.

### ⭐⭐⭐⭐⭐ Excellent Dayton Audio SPA250 - 250 Watt Subwoofer Amp. Excellent Calue !
*by J***B on June 14, 2016*

Awesome Crisp Clean Power: Dayton Audio SPA 250 - 250 Watt Subwoofer Amp. This unit is used in-line with my REAR ... Speakers 'B' Speaker Wires. Very Simple Set-Up: Speakers L/R Input and Output ... and a Dedicated Single Pair of Speaker Wires [16"] for the Subwoofer Speaker. I am using a Pyle PDIWS28 - Dual 8" In-Wall unit which can Peak at 600-watts ... and Continuous usage @ 300-watts. The SPA250 has GAIN / Frequency Response / and Phase switches - adjustments. The 'Auto on/off switch is left on at all times ... shuts the unit down when power from the Amp is turned off. Very useful feature. A Bass Boost Switch on top --- Selects a bass boost filter with +6dB @ 35Hz. It Allows the user to add boost to the low end response. Nice feature. This unit is designed to fit within a Subwoofer cabinet / enclosure. Mine is built into a Custom Rear [back of family room] Enclosure with L / R Rear Speakers. The Bass resonating from the power of this amp nicely Compliments / Enhances the Front / Main [Bose] Subwoofer. The entire room is literally filled with Music. Front Speakers are positioned lower to the floor ... rear speakers are closer to the ceiling ... total coverage at all volume levels. I chose this unit because my Receiver does not have a Rear or Second Subwoofer connection. This is truly an Awesome Amp ... Simple and Efficient ! Worth the Money -- Excellent Value !
