Which T-amp for Dynaudio bm15p Studio Monitors

[Waldschwammerl]

Hi,
I search for the best option to power Dynaudio bm15p monitors.
This monitors are not very evicient.

Relevant monitor specs are:
IEC Long term powerhandling 250W
IEC Short term powerhandling >1000W
Sensitivity 88 dB
Impedance Nominal 4 ohm
Impedance HF (200 kHz) 5,9 ohm(what does that mean?)

I want to buy one of the hifimediy amps for this but i am not shure which one is better.

1)This one has 2x100W@4Ohm:
Hifimediy T2 SE STA510A MUNDORF MCAP

2)This one has 2x300W@4ohm
Hifimediy T3S mcap

Id love to hear your opinions!
With kind regards,
Manuel

The big one for a studio, smaller one possibly for domestic use, rgds, sreten.

Might be useful to know that the tweeter (D260) can take some 130Watts RMS.

Hi, No it can't, not in a month of Sundays, rgds, sreten.

130W rms probably refers to wideband pink noise through a standard filter to the tweeter.

Hi,
Thanks for your answeres!
I also think I will get the T3s with mcap from Hifimediy.

Then i have two questiones about it.
1.)I will need to adjust the volume, and there is no pot. What kind of pot do i need to buy for this, and is it difficoult to solder it in?

2.)And what powersupply should i get?
I heared good things about this Meanwell:
Meanwell NES 350W 48V

And I heared this one is also good:
SMPS300R 48V 110V power supply

Would the two fit?

With kind regards,
Manuel

Hi Sreten.

The figure I quoted comes from the Dynaudio D-260 spec sheet. It says that it can handle 130Watts and 1kW peaks (10ms). Seems high. But then again: my experience to date with Dynaudio is that it can take some real abuse before compressing or overloading. No idea about real world wattage numbers, though.

I m looking for same thing , powering a passive studio monitor with diy amp but i m more interested in A class rather than D class , but I m still searchin about that , I m not sure if you need a preamp or a buffer before your amp, better ask the guys around here for that , and how are you gonna connect it to your interface ? I think if you r goin to use Balanced output from your audio interface it s better if you use a balanced/unbalanced converter , i m not sure about that either 😀 just to keep that in mind and ask the guys about that as well , I ll be glad if somebody answer these questions 😉

Regards

Hi Ahmad,
thanks for your reply and good questiones.
I thought I could use a balanced Audiocard and make a cable where one side is balanced and the other one just mono with one signal unconnected.
Would be glad if someone could confirm, íf thats allright....🙂

Cheers

I found this on net to connect a balanced to unbalanced input but still i think it needs a preamp ,hope somebody can answer that
