How much power do you need ?
What speakers are you going to power ?
I have had the Barbara Ann and now currently running the sony xmgs4

 

Sony was going to be my recommendation. Hard to beat for the money.

 

Those Sony amps are nice, Well built with quality parts and easy on the wallet.

 

The Sony xm gs4 would work well.

Depending on your source and crossover capabilities the us acoustics Kristy

 

I have a stinger heigh10 head unit in the Jeep. I never thought Sony would be a brand for an amp that would compare to the Barabara Ann

 

The sony xmgs4 is a nice amp for $200.
It does more than rated power, is dead silent and sounds really good.

I actually like it more than the Barbara Ann I had before.

The xmgs4 is a known budget SQ amp on diy mobile

I use two of them to run my front stage.

 

just curious why you say you like it more than the Barbara Ann.

I’m also wondering if the Sony will produce enough power to get the same volume as the Barabara Ann does.

For added info, I am also running an FI audio 12” Neo 3.5 in a ported enclosure on a teramps smart3. I really like the way it sounds now however, I am only running the CDT 6.5s and a pair of Hertz DCX 87.3s (one is blown I think) off the Barabara Ann now. I’m looking to get the other cdt 3” coaxles mentioned above to replace the hertz soon, as they will take more power, sound better, and hopefully get louder.

 

Most amps are rated power at 40hz

By the time you start using crossovers at higher frequencies it starts reducing the power midrange speakers and tweeters will actually get pretty dramatically.


Most tweeters will never see anything above 5-10 watts. Audio frog wrote an article on this.

If you don't belive me measure the voltage at 40hz with an o scope and set your amp gains. then go set 5k high pass filter and measure the voltage out. It will be greatly reduced.

Also when we are setting gains we are using a test tone say 40, 80 hz.
When we play Music it will almost will never reach the power watts we think we are actually sending to the speaker.

There is nothing wrong with the us acoustics Barbara Ann. It is actually a nice amp.

My only issue was space in my tundra. In my son's mustang we had enough room for the Barbara Ann.

Also at a retail of $400 on the Barbara Ann I can get two of the sony xmgs4.

I am running one amp on channels 1&2 to my tweeters
Channels 3,4 bridged to my 6.5 inch
The other sony amp channels 1,2 to my 3.5 's inch. Channels 3,4 bridged to the other 6.5 inch. So for $400 retail for both amps I get all the power I need.

The sony xmgs4 is just a good sounding amp at $200. They just perform.

this may just sway me enough to see if I can get enough money out of the Barabara Ann to pick the song up. Thank you for all the info. Greatly appreciated.

 

You can do the math.

92 dB + 10* LOG (30) = 106.8

85.7 + 10*LOG(50) = 102.7

Add 3db to both to account for the 2nd driver (incoherent addition).

This assumes the sensitivity is listed correctly for both drivers.

I assume both would meet your output needs.
