Sorry, I've no experience with Behringer amps. But do you know who is the distributor locally? Hopefully they can do demo, then after that I will have some thoughts on it.

jchong, from the product sheet, it looks quite good value for money.. at least thats in my newbie opinion la.. what you think based on d product sheet?

Based on product sheet the specs look ok. Then again, you really cannot tell performance based on specs alone.

Ultimately have to let your ears be the judge.

87dB but impedance is 4~6ohms, which is quite pwr sapping even though its power handling is 20-250W.

When I ran my auddysey previously, it detects these as full range speakers. What I knew is that 4310 aint up to the task. Time to scout for beefy power amp liao.

Yup, looks like a power amp is called for smile.gif 87dB sensitivity is on the lower side. That means your speaker is twice as power hungry as a 90dB speaker.

You keeping the MTS-01 for yourself or is it eventually going to be the demo model in the showroom?

what is SPL Anechoic 1w/1m(db) & why is this lower?

As taqies already mentioned, anechoic is measured where there is no echo/reflection. In a room, due to the room boundaries you will get additional dB from the reflections.

Ah, you mean light reflective! I thought you're talking about sound reflection.

The last time when I mentioned 'clean', someone mistook it as the characterisctic of the avr. What I meant was that it is free from 'coloration' and loss of details that are associated with 'peaks' and 'valleys'. What is the correct term to use?  sweat.gif

Beats me what is the term to describe the sound from a flat freq response graph.

Even the term 'clean' is not clearly defined. Yes, it connotes free from coloration - but coloration is not only caused by peaks and valleys. Coloration can also come from distortion (which is a function of the amp and driver). Some people also say 'clean' is being free from boominess, which can relate to ported vs sealed. So yeah, it's confusing out there... smile.gif
