Dayton Audio SPA250 250 Watt Subwoofer Plate Amplifier

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.

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.

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 !

The amp was in great condition and performed as expected.

I ve purchased 2 of these to power klipsch in wall subwoofers in separate sound installations - kitchen and living room. I've spent hours trying to get some at least some appropriate bass response from the subs. I ve connected it all the different possible ways, trying to play with equalizer, settings on the receivers... hopeless... boomy, loose amd absolutely upsetting performance. Then, i decided to give another try. I disconnected amplifier from my old powered yamaha sub and hooked it up to klipsch in wall sub. Ohhh lord. Such a difference! I can hear absolutely beautifull low low low bass, tight and dynamic. I don't have to cranck controls all the way up to squeeze juice from sub having bass setings flat. Works sooooo much better! Now i can def hear what i paid for over $500! DO NOT USE THIS PRODUCT FOR INWALL SUB. IT WILL NOT GIVE YOU SATISFACTORY RESULTS! INSTEAD LOOK FOR SOME OTHER SOLUTION: GET A POWERED SUB AND USE ITS AMPLIFIER! OR, IF BUCK DOESNT MATTER GET KLIPSCH. I HAVENT TRIED IT BUT HOPE IT WORKS JUST AS WELL OR BETTER!

The plate amp for my 10” Velodyne sub had a tough time kicking in when there was a signal. I would have to disconnect the RCA and then plug it back in to resuscitate it. It finally got to a point where it didn’t help, plus I don’t have the soldering skills so ended up looking for a replacement plate amp. This fit the bill perfectly, quite literally. It’s exactly the same size as the original amp, and the screw holes even match up perfectly. It was a simple installation involving removing about a dozen screws, and then popping off the amp enclosure. The back of the enclosure required a little persuasion as it was glued to the sub box, but I was able to remove it without too much effort. In all, it took about 10-15 minutes to install, and I have some low end sound again.

I purchased one and it lasted 2 months, needs lots of room and lots of air. I rebuilt my bandpass keeping the second one separated and it's sounds great. Needs lots of air moving across it to stay cool. Goes into protection easy on slight power draw. Make sure to get the protection plan I learned my lesson. I am using a 250w polk sub in a 4th order bandpass in a ported audio closet , sounds fantastic Hopefully moving the amp out of the box will extend the longevity. I'm very pleased with the performance , durability is questionable

The Dayton SPA250 is a nice powerful sub-amp with a good low end punch, not just for music, but movies, it delivers a clean low end without being to "on your face" sort of speak. You can feel the bass coming thru clean without any major volume increase to help it. The controls are simple, and the connectivity to either an existing subwoofer or a new one is pretty easy to do. However, if you are replacing your plate amp for this one, be ready to customize the existing open, as this amp is a bit larger on the back. But if you are savy and got the tools, is not a big deal. Anyway, great amp for the money!

Livraison très rapide (2j après la commande) malgré les 7j annoncés. Carton bien sécurisé. Matériel utilisé en remplacement d’un Bower and Wilkins Asw 675. Son excellent même à très faible volume. J’aurai bien mis 5/5 mais la prise secteur fournie est de type US, c’est le seul bémol et bien des moindres. Installation complète en moins de 10 minutes. Pensez à switcher de 115v (par défaut) vers 230v

Powers my 10" inwall sub fine. Sounds better than the iNuke is was using before.

nice amp, just enough power to make my cabinet work

My surround sound setup includes NHT SuperZero, SuperOne and Supersub speakers. I love the clear sound they produce and their piano black finish. I was a bit distressed when my SuperSub developed a loud hum since I knew that it would be costly to replace. I decided to look online to see if I might be able to replace just the amp portion and found the Dayton Audio plate amp series. The size, specs and appearance of the SPA250 looked closest to the original amp in my SuperSub so I ordered one. When it arrived I was surprised to find it is almost identical to the NHT SuperSub amp right down to having the screw-holes in exactly the same position. I didn't examine the internals of either amp but from the exterior they appear to be clones. The SuperSub sounds the same with the new Dayton Audio SPA250 as well. I'm happy to have my SuperSub back in operation in such a seamless way, However due to the failure of my original identical appearing NHT amp I am changing the way that I use it. Previously I left the sub permanently set to "auto-on" even though I used it rarely. It developed a hum even though it was in "sleep" state. It appears that some components are electrified and degrade during "sleep". I still have the sub set to "auto-on" but i is now powered by a circuit that is active only when I'm in the room. I'm hoping that this will extend the life of this replacement.

Good quality bass with all the adjustments you need. Just be carefull with the micro switch for 6db boost. It's fragile. I broke mine but luckily, I fixed it.250 watts is on 4 ohms woofers. Its about 150 watts with 8 ohms woofers. I realy like the fact that it comes in its own case. I just added four rubber feet and a five way speaker connector and I can now connect it to the woofers on my speakers. You will need two amplifiers for stereo application.
