Receiver: Pioneer SC-27
Currently, the C4's are hooked up to Pio, I tried bi-amping since the receiver is a 7.1 system however I did not really notice a big difference with the sound. I feel like that I'm not really getting the most out of the subs on the C4. So the options I came up with are:
1) Buy a new sub maybe HSU VTF-15
2) Buy an additional amp: I know when the C4's first came out they were matched with the A1 amp and X2 crossover. It seems these products have been discontinued. What alternatives are there to power and get the best sound out of the C4's?
Basically I want to fully utilize the C4's sub and would like the most cost-effective way to do so. Appreciate any advice on the setup or possible alternative options.
Thanks in advance for all your help!
You would need an electronic crossover like the X2 from NHT (now a vintage product, so look for used) and a 2 channel amp to power the subs for the Fours separately from their upper portion. You can also use another crossover like the Behringer:http://backstage.musiciansfriend.com...182466.product
The thing you need to keep in mind is that the Fours' sub is internally XO'd at 125Hz, so you'll need to set the XO near that point or you'll be missing some Freq in that range (i.e. if you XO at 90Hz, you loose the 90-125 portion of the freq range).
The main advantage of using such a setup would be to increase the power to the sub portion of the Fours, but IMO the best best would be to spend money on a more powerful sub (or subs), you'll get more bang for the buck and much better sound (ideal placement of the subs are not usually the same spots as your mains). I actually crossover my Fours at 60Hz (at the usual 12db/octave in most AVR's, there is still energy at the 30Hz point, an the dynamics for the driver increase since it does not have the heavy bass load, which subs are designed for).
