Minimum Watts required

I have always been curious just what this really means . For instance , i have ALS,s.....recommended power is 350 watts minimum 1000 max....Now I understand the max part...But what about the , minimum ? I know that my TMF 35 is 350 watts at 4 ohms....Thats at full power , even then they dont sound good....I guess my question is , what do they mean " Minimum power "

Thanks ahead of time....

Re: Minimum Watts required

The way I understand it is just that, your speakers require a minimum power to operate correctly. My MB Quart's state 110 watts min. 180 watts max. I am running a TFM-15cb that is 100 watts per channel, so am I not giving enough wattage to my speakers? Am I hurting my speakers? I don't know? Hopefully just 10 watts will be ok, I do need more power, yeah that would be nice. Good question Steve

Re: Minimum Watts required

Minimum RECOMMENDED amplifier power. If you never listen about polite conversation level (many don't), then that would be plenty of power. So much depends on your listening level~

At polite conversation level, people are not listening.

Re: Minimum Watts required

I can talk from recent experience, the Phase Linear speaker 100 watt min. that I recently picked up. They sounded very bad with my 20 watt tube amp but great with my M500 @ 200 watts, both at the same listening level. On other speakers at listening levels,the 2 amp sounded great, with the edge going to the tube amp.

Re: Minimum Watts required

I am a firm believer in having more power than needed. Just don't use it. :-k :-k Call me crazy, but it seems to me that heavier amps tend to give better sound at lower volume. It may also allow the amps last longer by not beating the shit out of them. :-k :-k Just a thought. I am running a set of Snell model B speakers with a TFM-55. The sound quality in the 19 to 25 watt range ( 4 ohm) is amazing. That amp can destroy these speakers.

I agree...you can never have too much power. Just need to be smart about how to use it.

Re: Minimum Watts required

Steve,
Do you have ALS originals with the two 30" ribbons? If so, they can dip as low as 1 ohm which is very hard for your TFM to drive. Start saving for a set of Silver 7t or 9t monoblocks and you'll have all the power you'll ever need and amps that can handle any loading down to 1 ohm with ease.

Good choice. A 600x2 should work fine.

Re: Minimum Watts required

I think you'd be better off with a 300x2. I seem to recall Bob saying something about it being more stable into low impedance than the 600.

Re: Minimum Watts required

Watts are overrated. A high current amplifier that is capable of handling a low ohm load will properly power those speakers. FYI, there are not many amps out there that will do them true justice at all volume levels. Out of the Carver lineup amps I have heard with these speakers, only the 9t [7t would be about the same, just never heard one paired up with these speakers] and the Lightstar amps made these speakers sing.

As far as Sunfire, the 300 x 2 would be a good choice as well. I haven't heard that amp, but I did have a chance to hear a 300 x 7 at CF and it had plenty of juice to make them sing.

Another amp that you may consider would be one of the tube amps that Bob is currently building. Out of all of the aforementioned amps, the tube amps would be my choice. Why? I love the sound of tubes, YMMV. Hope this helps.
In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.
