Klipsch Forte IV ... what amp ?

No , I am not asking for a particular amp style and brand here . Although I am not refusing any suggestions either !

What I would like to know first is what characteristics to look for in an amp to drive these speakers (Forte 4’s) to full performance .

Such characteristics as :

1.) What is needed to handle the low impedance of 4 ohms ?

2.) While the sensitivity is listed at 99 dbs. it is considered to be closer to @ 96 dbs,

3.) What about negative feedback ?

4.) Will the 12" woofer and 15 " rear radiator need special attention also ?

5.) Do the horns require special consideration ?

I feel that these considerations will go further to getting it right than , " hey , just get a tube amp and enjoy " .

Thank you & Be Safe .

Hi All,

I posted this earlier in the thread: "...The Forte's were very harsh with the DNA-500. Really don't really know why, but not a good match...".

To set the record staright:

I reinserted the DNA-500 amp with my Forte's and was suprised. They do not sound at all like what would lead me to post the ealier comment.

Sound staging, dynamics, and a "like live" sound are all present now. And the hiss is pretty much gone.

Don't know if it is my hearing getting used tio the speakers or the speakers are breaking in...

Anyway, the DNA-500 sounds good,

I just purchased a pair of Forte 4’s a week ago, and the listening session I had with them was fantastic. I am driving them with a Music Reference RM 200 tube amp, coming from a Rotel 1590MK 2 preamp. (My other speakers are JBL L100 Classics)
