Wiring Multiple Subwoofer Drivers


 I’m in the process of installing new sub drivers(Dayton Audio RSS265HF-8 ohms impedance) into my pair of Kinergetics SW-900 cabinets. Each cabinet will contains six 10” drivers. I have two options for wiring them & can’t decide which to do! I would like to know if one is better than the other & the pros/cons of each. The two different wiring diagram I’m considering are:

2 sets of 3 series drivers run parallel= 12ohms

3 sets of 2 series drivers run parallel= 5.3333ohms

 

12ohms:

Pros- higher damping, less distortion, less resistance, less wire

Cons- less power

5.3333ohms:

Pros- more power

Cons- less damping, more distortion, more resistance

 

My audio pro friend (who is much smarter than me) is assisting me with the subs, he states wiring them for 12ohms is better.  But if that is case make OEM drivers & speaker designers make the products 4 to 8ohm impedance normally?

Thank you for any input, advice or suggestions!

Thank you for the info/response millercarbon! Sound quality is first,but I want plenty of undistorted output also. I do both music(60%) & home theater(40%). If I go 12ohm setup, my hope is that the sensitivity will be high enough(95db) I won’t need massive power to get high(110db at 25hz) quality output. But I don’t want to wire them for 12ohm & find out later I can’t get the output I need/want. The amp I plan on using will be PS Audio Stellar 700’s which output 300watts into 8 ohms.  

Regarding the cabinet choice they were pre-made by Kinergetics Audio. I don’t have 4 of them so 2 cabinets will have to do, for now. Plus, twelve 10” woofers should awesome in the sweet spot.

BTW, I called Ty from Tyler Acoustics & he suggested I go with the 5.3ohm setup.


Thank you imhifiman for the information on the option of using a toggle switch to switch the ohms from 5.3ohms to 12ohms on the fly Plus the schematic on how to wire the drivers for that. Much appreciated! If that works I can use position 1 for home theater(5.3ohms) for output & position 2 for music(12ohms). That would be awesome! J I’ll have to run that by my ‘audio guru’ friend(Lorin Peterson cofounder of Threshold & Coda) who is helping build them.

Mijostyn, three things. First I cannot lay them down on the floor due to space constrictions(fireplace right side, door left side.  Second, The main speaker I’ll be mating them with are 7.5’ tall(Dali MegaLines) with twelve 6.5” woofers per cabinet. I think they will blend much better next to each other. Third, the cabinets which I just got done stripping/sanding for the past 4 months are a beautiful walnut veneer(cabinets were painted black over the veneer) & I want to enjoy looking at them as much as I’m going to enjoy listening to them! They should look great once completed. I do like your idea of using granite to deaden the cabinet though. I plan on using a piece on the bottom & one on top. Thanks for the input!

 

millercarbon,  it amazes me that you & my bud Lorin believe the sound quality is so much better with the higher ohm load. Lorin did enlighten me on one fact I didn’t know- The higher the ohms load, the greater Class-A output. So a amp that does 10watts Class-A in 8ohms, will be 20watts Class-A into 16ohms. But will only do 5watts into 4ohms. So maybe that is why the increase of sound quality?! Which means less distortion also. Plus, I’m hoping the sensitivity of the speakers will be 95db so I won’t need much more power to do 105db. I just don’t want to my Jurassic Park dinosaur stomps to suffer.  Thanks for the input!
