SPA250 250 Watt Subwoofer Plate Amplifier

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 !

Good replace for my B&W sub. The holes lineup but needed to be drilled out a little bigger. Sounds good.

Great amp works perfectly and stays cool

I purchase this unit to replace a busted amp in a Polk audio psw650. All it needed to take this new amp was to widen the existing plate hole by about 3/4" top and bottom. Was able to plug it right in, silicone seal it up and it works great as advertised. Nice that it handles 8 or 4 ohm drivers the same.

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!

Broke after a few times using it. Had it repared,

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

Had to reconfigure the hole in the cabinet which took a sabre saw and some glue. Performance is way way better than the polk amp. It is much tighter sounding with way more power and it blends in more seamlessly than it ever did before. It is in a 40'x40' shop with a 16' ceiling backing up 3 sets of classic Advent speakers (2 pairs on tuble amps , one pair on SS amp) and it sounds better than it ever has. If this amp, which weighs way more than the original amp, keeps working as it is now i will continue to be glad i went this route over purchasing a whole new sub.

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.
