Default WTB: subwoofer plate amp

Looking for a subwoofer plate amp to give to my son as a Christmas present. He's building a HT sub with an Adire Shiva 12 I purchased from Timn8er.
I would prefer 200W or higher
Thank you,
Ron

Hi Ron, you're in luck.

Parts Express has a one day 40% off sale on a 500watt plate amp today only. They are also offering free shipping and check the website for a $20 off coupon for orders over $125.

Almost all their Dayton plate amps are on sale for Black Cyber Monday.

Heck of a deal.

PB2,
I have used the 250W version in a Titanic MKIII 12" subwoofer I built, the driver was modeled after the Adaire. I keep my sub at 1/4 volume and it works perfect for our Home Theater. I don't use it for stereo listening.
SQ wise; no hum no buzz. plenty of power, on auto standby all the time. 2years and no problems. turns itself on when signal is sent.
Great buys and quality amps. Runs cool
My son has not built his sub yet............

I'm certain it will be wonderful.

Ron

Peter,
Looking at your website is an education in itself. You have forgotten more than I will ever know about audio.
On your TC-50 speakers the solid copper binding posts are "Edison Price Music Posts", some of the best you can (could) buy. I bought a set from Michael Percy for my Thors.

Edison Music Posts are now ~$70 a pair. OUCH!

Wait for a "Special" and you can pick up a plate amp at a great price.

Ron

Hi Ron,

I had a feeling that those posts were high end, but honestly was not sure of the brand. Thanks!
$70/pr LOL!

Thanks very much for the nice comments.
I don't use plate amps much, and it helps to get some feedback from users especially about reliability, so thanks again.

I will probably go with the PE, it is an excellent value.

Also looking at this 500W BASH O-Amp:

Pete,
That Bash is a very nice unit, it won't disappoint you. What driver are you going to use?

Have you thought about a Rythmik?
Rythmik link

Ron

This really should be moved to it's own post...

But, since I started this thread, I don't mind....... LOL

Ron,

There are so many new drivers out there. I'm thinking of trying to keep the box under 2 cu ft, probably 1.5. I usually go
vented but might try sealed with one of the new high Xmax drivers and a lot of power. Seems you can never have enough
Xmax in a sealed situation. I'm planning for a pair for stereo subs.

There are a few things that I'm not liking about many of the new drivers.
I prefer metal formers, many are using Nomex and other non=thermally conductive materials. Yet, they still seem to claim high power handling.
Drivers with aluminum cones should use the cone as a heat sink IMO, not sure which companies are doing this.

I prefer a large spider, many long throw designs do not seem to have large spiders, have to wonder, or look at Klippel
data to see if they are really linear.


It is difficult to predict large signal effects such as compression, motor linearity, and overload behavior, since most of the spec data is small signal.

Noticed your signature there .... a spin on the more you know the more you don't know?
