bk electronics 500w plate sub amp (1 Viewer)

[Dan Baxter]

I'm thinking of using one of these amps: http://www.bkelec.com/Diy/bsb500.htm in a diy TUMLUT sub project. They seem like a pretty good deal for a 500w plate amplifier with no fan. The price is about $350 with the currency conversion.

That looks like the the same amp that's carried by the Art of Sound.

I've got one in my sealed tempest and it works a treat. I would have thought that you'd get better value for money in the U.S. though? I only went with BK because I'm based in the U.K.

It seems like a pretty good deal for a 500w amp. Does it have plenty of power for your tempest? Also, how is the build quality of the amp? Does anyone else have any recommendations on a 500w plate amp with out a fan?

Thanks

Dan,
I posted a similar question at the following site and got some good feedback.

If you look under the classified adds (sub directory) at www.audioasylum.com you will see an add for the same amp from ArtofSound and the price is only $350 and the shipping will be less from the US.
My concern with this amp is the powersupply. I like to use weight to help determine the strength of a powersupply. From the BK Electronics web site the BSB300 weights 14.5 lbs while the BSB500 weights 15.5 lbs. It looks like they are using similar PSU's even though the BSB500 is expected to put out almost twice as much power. As a comparison the Hypex HS200 weights 16 lbs and the HS500 weights 24 lbs.

Steve - good call and a valid concern.

As far as build and power goes it's excellent. It's got a large toroidal transformer to power it and seems to have plenty of headroom. To be honest, I'm sure a 300W amp has enough power, I just bought the 500W one because I didn't want to have to buy another amp if it didn't have enough grunt.

Reading the feedback from Gary Griffiths it sounds like the amp's not up to much compared to the competition, although I'm using my sub for music ( with some Epos floorstanders ) and have found it integrates well, particularly once a Behringer Feedback destroyer is added to tame some of the peaks. The module I have as a 'soft-start' so there's no power thump when you turn it on and off, just the click of the relay.

Cheers

Simon

Dan has just confirmed at the following link that they will be selling the DT300 amp from RCMAkustik. He also compared the DT300 to the BASH 500W , HS200 , and AVA250 / PE amps.
