Moving to Horn speakers

So long as one uses a reasonable amount of caution, too much power in an amp is typically not as much of a problem as not enough power. Having said that, my thoughts are that Lowther's are more fragile than most "hi-fi" type drivers, so treat them with a little more respect than you might normally bestow on a bigger, more rugged beast.

As far as power amps go, so long as speed, bandwidth, linearity, stability and class of operation ( bias level ) remain consistent, the amp with more power will typically sound better and work in a wider variety of situations. When one of the factors that i mentioned differs between comparable models, what you like best is strictly a matter of personal preference.

Twl: When you mention 108 dB peaks, are you talking at 1 meter, at a random listening position X feet away from the pair of speakers, etc... ? Sean

Which Lowther drivers are these and what are they rated at in terms of 1w / 1m in stock form ? Sean

Part of the problem with these is probably due to their limited X max ( excursion ). Then again, drivers with a longer X max will also typically be of higher mass, hurting their high frequency extension and transient response.

As far as Lowther claiming these to be the most efficient drivers, they are WAY off their rocker. Sean

Twl: Your first post regarding Lowther's claim made no mention of "full range" drivers. As such, my response was based on that info. I don't know what is out there in terms of "wide bandwidth" drivers, but there are surely many, many drivers that are WAY more efficient than what you stated. They just don't cover the full frequency range. Sorry for the confusion. Sean
