Powerful enough for my speakers?

Default Powerful enough for my speakers?

Why not take your speakers to where you are buying the mini system ?
Mini systems are not usually the best solution to high quality however as
the most compromised part will be the speakers you are better to keep
speakers you like. Actual wattage quoted is irrelevant for sound quality
and makes only a small difference in terms of maximum volume output. You
are unlikely to use more than a watt or two to drive your speakers at
"normal" levels.

Hello,

I'm considering buying a Teac 300DAB mini system, but keeping my old
Morduant Short MS3.30 speakers. The specs of the amp (AH-300MkII) say
"45W + 45W (6 1/2, 1kHz, 0.5% THD)". This means little to me, but I
guess that the 6.5 is the impedance, so the amp can do something like
35W RMS per channel to my 8ohm speakers.

Is this enough power? My living room is quite large at about 5m x 6m and
is carpeted, but I don't play my music particularly loud.

If it's just not powerful enough, I guess I'll go to Richer Sounds and
buy a 540A+540C+640T combo, but it's bigger and costs approx £600.

Thanks in advance for your guidance.

Chris.

It should be enough power.
Make sure you don't compare the Mordaunts to any decent speakers. :-)

Sounds like it's not powerful enough to me!

Good. Thanks (& to Richard too).

Ah now, you can't dis my old speakers without recommending an upgrade.
Nothing expensive either - I can't hear the hi-fi anyway with the
children yelling at me :-)

Just ignore the **** - I'm using MS20s in the kitchen, and they still
beat the pants off most of the current stuff below 400 notes. Robin
Marshall is one of the best speaker designers this country's ever
seen, and his 'minimalist' MS designs are classics.

In the kitchen - possibly the best place for them. :-)

I acquired a pair of MS3.40s, which I assume use the same tweeter
as the MS3.30, from a friend. These are in as-new condition and sound
generally quite nice. Yet in comparison to my other speakers the treble
is not clear. It sounds smeared, turning triangles into cymbals IYSWIM.

So go ahead and compare. I'd be interested to read your opinions.

I have some 20 yr old MS 55Ti floorstanders. I thought
that they were sounding lacking in treble bite and image. Then
I bought a lot more power and... Yes clear top and more solid
bass. I think MS speakers need *oodles* of power. I'm hitting mine
with 200 wpc. Big room though. I was told in this ng that MS
speakers have high power headroom and that mine, though
nominally 150 wpc actually have a protective device that stops
them at 300. I would have doubts about the power suggested
for the size of room.

45 watts into 6.5 ohms means the amplifier can produce a signal of 17v RMS.

Why not connect an AC voltmeter across your speaker terminals, and see what
signal level you're using? If it's less than 17v, the new amplifier will
drive your speakers as loud as your existing amplifier.

If you're going to use it to listen to DAB it does not matter at all what
kinf of speakers you use.
DAB is not hi-fi.
