Full range drivers and T-amps.

[Bill poster]

Looking at getting a T amp with the tk2050 chip to drive my next design - looking at the Helder hifi pcb's and also the Hifimediy dac (AD1853), to run off batteries.

Does anyone have one of these little fellas rigged up? How do they sound with full range units?

It's been about a year but my first experience with full rangers was a pair of Sachiko double mouth back loaded horns with some slightly modified Fostex 206Es in them. I think I tried every amp I had available including a Sonic Impact T-Amp (3wpc?) I'm a fan of the way the T-Amps can sound with the right speaker and this combination did not disappoint. I did NOT push it to find it's limits but felt that said limits were probably well beyond the comfortable listening levels in my room. YMMV

Yep, I'll second that. Had mine on quite loud the other day, so loud my friends arriving(student accommodation) could hear it when they were outside and I think in their car. I didn't realise this as there is so little distortion(and the dial was only on 2'o'clock). I'm running a commercial t-amp with Ta2024c chip inside, with some temporary mini open baffles using Fe103e's and a sub. Mine has 10w at 8ohms.

Sound is pretty good, even with my old cabinets I were using, which had many floors, people when round would ask me about them.

The full range drive units I'm using are only 85dB/1m so I won't get away with the lower power T amps unfortunately so it looks like I will use an amp with the tk2050 chip. I would like to fit a tube( in the outputs?) but know nothing about how to do this.

I'm really liking my Sure TPA3123 with my FH3's Sure 2x25W @ 4 Ohm TPA3123 Class-D Audio Amplifier Board

I might add, I'm only running it at 12V (SMPS).

I like my t amps... have the SI original, the Dayton clone and the 50 watt Dayton.

Dayton Audio DTA-100a Class-T Digital Amplifier 50 WPC Provides Power To Computer Speakers, Bookshelf Speakers, Headphones, And More!

For whatever reason i seem to prefer the cheaper amps. With the expensive Dayton the channel balance is off at low volumes but evens out when louder. It's a bit annoying. The cheapies are perfect for what they are.

People say they lack bass but i always hook up a powered sub of some kind and let these amazing little amps sing with efficient full rangers.

Nice thread. I didn't feel like starting a whole new one just for this question:
I'm putting a FR and t-amp setup together for my sister. The budget for the amp is around $200.
It seems like there is a jungle of potential candidate t-amps out there.
I'm driving CHP-70s so I need more than a TA2024 equipped one.
The Dayton doesn't take 4 ohm so that is ruled out.
Virtue, which I have, and is happy with, is way too expensive in Denmark.
I've looked at the Hlly tamp-90.
Are there other (better?) alternatives out there? No DIY please (I realise the irony of posting this here, but DIY speakers are involved, so...)

I was contemplating this - if its 25 watt per channel into 8 ohms(it doesnt say) then its worth considering. I sent them an email to clarify but havent heard back yet

I have a Temple Audio amp. But the normal one. Pretty good. But obviously that will sound different. I got mine for peace of mind as I wasn't sure on my electrical skills otherwise i would have built one of the kits.

Just spotted a Hlly TA2022 board on ebay for 40 quid inc shipping.. v tempted! Should be enough to run even very low sensitivity full rangers
