![]() When I started trying to disassemble the speaker I got the feeling that this was modified before. I have a Denon 3808 that I can use straight away, but I was actually thinking of putting together an ice power 500A based amp.Ģ) I am tempted to pull the x-over out and bi-amping the speakers, leaving the pass amp for the mid-high and a more powerful unit (ice power?) for the bass. I have various things in my mind:ġ) Try a more powerful amp. I first was thinking just to sell these speakers, I have the concerto home that do very well. This is a balanced version of the F5 with 30W class A power. The speaker are in the living room and the structure is not symmetric.Ģ) I am driving them with a Pass Firstwatt F5-X. I might have problem outside the speakers:ġ) I do not have a dedicated room. I am having a bit of problems with these speakers, the sound is like disconnected, like the drivers are singing on their own. I'll try to post a picture of what I found behind the bass reflex duct. Not that there's anything wrong with that. They may have used cheaper parts in this model (my Concerto Grand Piano had much better crossovers - so the voice coils went before the crossover!), but the design is good :thumbsup:Īnd I am a guy, not gay. I ran a couple in parallel which makes it easier, but adds to the cost. You will need to go up, stacking them and using plastic ties to secure them in place. This exercise will be like trying to fit several elephants into a small tent. It makes a big difference :music:īe aware that the film caps are massively larger than electrolytic caps. But if you are going to make just one change, put a film cap on the HF driver. The caps on the bass aren't so critical, but I changed them all. I used Jantzen, but you could try Mundorf Supreme (which SF use in their premium speakers) or Clarity Cap, etc. Change them for a film cap of your choice. The capacitors in the Domus GP are not good - Taiwanese electrolytic. After 2 hours of high output, the resistors will heat up the board so much that the solder will melt, the capacitors and inductors will fall off, and you will short the amp.īy using Mills resistors, you can sit them up on their leads above the board, and fan them out, which will give much better heat dissipation I doubt whether the resistors themselves will affect the sound quality much, but the OEM resistors are unfortunately placed directly on the circuit board, 2 across with 1 sitting on top in the middle. ![]() I replaced the 3 cement resistors with Mills. Is this something I should consider? Have any of you guys/gays done something like this? The GPD sound really really good and I can't leave well enough alone :nono: The awesome members on the Polk Forum assisted in great detail how to successfully complete this upgrade. I have done this to some of my Polk Audio speakers in the past. Note that all items valued over $750 will require a signature upon delivery.I am giving thought to removing the x-overs from my Grand Piano Domus speakers and upgrading the capacitors and resistors.
