Bash 500S Digital Subwoofer Plate Amplifier 500W RMS
Bash 500S Digital Subwoofer Plate Amplifier 500W RMS is rated 4.2692 out of 5 by 78.
Rated 3 out of 5 by from SQ far from good but it works and does rated powerOwned for over a year now and it's still working. Had to replace one of the fuses, no idea why it blew. Upgraded the speaker wire and terminals going onto the board. I've used it on a few different subs/enclosures and it is loud and definitely does rated power, if not a tad bit more than rated power.The limiter circuit, as a previous reviewer stated, needs some work, or needs removed completely. It absolutely kills every bit of sound quality this amp may have. The limiter is constantly adjusting itself not only at high volumes but medium volumes as well. This leaves me constantly adjusting the "volume" knob for different media, switching between movies/music etc. The limiter is not as noticeable on movies, but music is another story. This amp is not for music. The limiter also gives the amp just a plain muddy sound. It's not tight, nor accurate, nor even sounding, no matter the enclosure type. I've tried sealed, ported, and T-line boxes, and even the sealed enclosure sounded muddy.The 6dB slope crossover leaves MUCH to be desired. Even with the crossover set at 50hz, voices and midbass still come through, how much they come through depends on the enclosure and my T-line box is what brought me to notice how weak the crossover is. With my T-line, it's almost as if the crossover isn't even there. And yes the LFE switch is switched to crossover so it's not the LFE switch, and there is a difference between LFE and crossover, so it's just a really really weak crossover. A selectable 6dB/12dB/18dB/24dB switch is needed and would be perfect.I dabble between home and car audio and consider myself an "audiophile"/SQ kind of guy, and usually home audio manufacturers have the sound quality enthusiast in mind. Not the case with this amp. My car subwoofer amplifier is leaps and bounds ahead of this amp in terms of sound quality and it puts this amp to shame. It has selectable 12/18/24dB crossover switch (yeah, they didn't even bother with the useless 6dB crossover), adjustable bass EQ frequency and level, a high damping factor, and no darn stupid clip limiter, which makes for a darn good sounding amplifier. Take notes, BASH engineers.I gave this amp 3 stars because it still works and it does rated power. Those are the only good things about this amp. I suppose it looks nice as well. The build quality is meh. The sound is meh. The power is good.

Rated 5 out of 5 by from Bash 500sNice plate amp. 1/4 turn on the power and the house shakes. Great price point and value. 300s is probably power enough for most sub applications in home theater, but all the headroom makes a person giddy. 500s if the neighbors aren't cool. 185 dollars. Definite loud power.

Rated 3 out of 5 by from Meh. Limiter circuit limits sound quality too.Lots of power, but you can hear the current limiter working, even at moderate levels. Transient punch is reduced to transient smoosh. This is compared to running the same sub on an old Adcom GFA-555. That may not sound like a fair comparison, but I am referring to the sound at moderate levels that should not tax either amp.Also, after about 18 months, mine blew a pair of mosfet switchers in the power supply. I've repaired it, simply by replacing them, but in the process, I observed that there is very little overkill in this design. It's components are running near their limits. The capacitors are pretty cheap. Very nice circuit board though.Ultimately, this is built just like a mid-range computer power supply.Meh.

Rated 5 out of 5 by from Polk Audio PSW 1200I have a Polk Audio PSW 1200 which is the biggest home audio powered sub they ever made. Dual 12" subs weighing in at 110 lbs. I bought this thing new and had it now for about 10 yrs. The amp went out in it and Polk has no replacements so I had it repaired which lasted about a yr. Researching a comparable replacement amp that could push two 12" s I took a chance on this amp. This amp is slightly smaller than the original Polk amp so I made a plate out of wood and mounted this amp into it. With this amp it put this sub to a new level. The amount bass this sub puts out now far exceeds the original set up from Polk. They cut themselves short by under powering the amp they put into it. I mainly use my system for home theater and it's like a new piece of equipment. Last night we watched Polar Express (yes, it's Christmas eve) and when the train came down the road I thought it was coming through my house. Very impressed and glad I resurrected an old friend by purchasing the Bash 500. Awesome job!!! My neighbors may not be as happy as I am though.

Rated 5 out of 5 by from Excellent!For my application this amp seemed to be my best choice for overall diversity. I run a coax from LFE on a Technics 5.1 receiver, sounds great so far. It's home to a custom 3.75 CuFt. Ported box(including bracing and internal weighting#. The box also utilizes a parts express 6"x17" flared precision port. Speaker is a MITEK 15" DVC#2 ohm per vc#. The amp is perfect for versatility, if down the road I want to scrap the current application I can use this amp for something else. VERY HIGH POWER and clean too. Zero distortion! Auto turn off works fine with the receiver I am using. Seems to be an efficient and cost effective design. No need to be concerned about the open design with exposed circuitry, you do not need to build a separate enclosure, it is made this way on purpose to help keep the amp cool. The exposed circuitry is extremely ridged, I would not recommend creating your own enclosure unless you use some sort of project box with internal fan#which would only draw dust into the circuit boards and heat sinks). If I hear a bass head driving down the street, I can easily break his windows with my bass from the house with this amp. PERFECT for music and home theatre applications.

Rated 5 out of 5 by from Bash 500 Watt Subwoofer Module and Eminence SubwooferI had a Boston Acoustic 300 watt subwoofer which is down firing and the module went out. I ordered the Bash 500w subwoofer module and the Eminence LaB 12, 12" Subwoofer. I built a front facing cabinet. 1.92 Cubic ft. with 2, 11/2 ports extending 9" into the Cabinet. I have the volume on the Bash set at less than half way. Watching Live and Let Die and the movie Olympus Has Fallen, it is awesome. It felt like my room was being disconnected from my house. If you want to find out what subterranean feels like this is an awesome pair. Other woofers might work just as well with the Bash 500 but I am partial to Eminence. I have been using them ever since the 70's and they stand the test of time and take everything you throw at them. I'm also using a Marantz AV7701 Preamp & Parasound A51

Bash 500S Digital Subwoofer Plate Amplifier 500W RMS

Does Bash make similar sorts of amps for full range audio rather than just sub-woofer use.

Asked by: KayToo
The only Bash type amps that we offer are subwoofer amplifiers. There are probably other types of full range amps available that use Bash technology, but I would not know where you could get them .

whats the damping factor and slew rate on this amp?

Asked by: JRS1

Will this fit klipsch sw-115 if not which one would?

Asked by: Dainis
We do not have a direct cross reference available for this. The dimensions are available on the website if you wanted to compare the opening sizes. Chances are an after market amplifier will require cabinet modifications in order to fit properly.

Is there a subsonic filter on this amp?

Asked by: dpdpdpdp
Yes, it is centered around 18 Hz.

I have a JL Audio 10w6v2 sitting around that I would like to add to my Basement system (HT/Audio).  The sub can be wired to 2 or 8 ohms.  Will this amp work for this application?

Asked by: John I
Yes, although the sub coils will have to be wired to 8 ohms for a safe load on the amplifier.

How would you go about connecting just one subwoofer to this amplifier?

Asked by: Dave69
There are only one red and black wire on the back of this amp to connect to the subwoofer. The High level speaker outputs are only passing the signal and are not powered from this amp.
