I need the cabinets to stack tops on so they need to stack and reach a height of 40-45" or in the TH118's case be that high. So I believe that puts me out of the market for any other Danley cabinet like the 218. 4 of those and I'll need two K6 amps so that will put me far over budget unless theres some place far cheaper than I've seen. So I guess I'm out of ideas on what other options to look at in the market...
That is a very common mistake people make when looking at cabinets.
It is not so much "what it takes to power them properly to full power", but RATHER 'how much it takes to get to a certain SPL".
With a higher sensitivity cabinet, you can use a smaller amp and get just as loud.
Or if you were to take it the other way and say "How many cabinets and amps would it take of XYZ cabinet to equal 4 Danley DBH218's on 2 K6 amps?
Then the picture starts to look very different.
TOTAL cost of ownership for a particular SPL and low freq response is what you should be looking at. Not just a small piece of the pie.
Just because a loudspeaker can handle a certain wattage-does not mean you HAVE to use an amp that size.
When people ask what size amp I recommend-I usually say at least ONE watt. For some cases this is enough (not usually-but yes it does happen and some people are happy with 1 or 2 watt amplifiers). However in most cases they need something bigger.
Just because your cars speedometer goes to 120MPH do you always drive it that fast?
If you use the "I have to have an amp the size of the rated power", then we will also assume you never driver slower than 120MPH.
Headroom is nice and sometimes needed.
Just something to think about.
