OTop impedence

#1 Post by himhimself » Mon Sep 04, 2017 5:43 pm

Is there a suitable driver to build 16ohm Otops? Thinking that would allow three in parallel and still a healthy 5ohms on an amp channel. I see there's a 16ohm version of the DR200 per Lelands site, but not for the Otop.
thanks

I've been running 3- 8 ohm OTops per side off a Crown XLS2500 for several years.....no problem.

Getting a 2 ohm per side capable amp is way easier than trying to build a 16 ohm OTop.....or doing a serial wiring scheme outside the box.

Would you feel safe doing this with 3 subs? Or do you run an individual amp for each pair of subs?

If you get a high-powered amp that's 2 ohm capable per side, you could run 6 subs on one amp with no problem....(even 8....but I wouldn't push it that hard).

I run one amp per two subs because I am using XLS1500s bridged. Plenty of power to handle 'em that way, but they are limited as they should be. Didn't intend to start that way, but as I added subs, it was easier to add the same amp configuration. I considered dumping the individual amps and going with an xTi6000 to handle 'em all, but the more I though about it - I can lose one amp and still have 4 subs running....so, I stayed with the three amps.

Thanks Bruce.

I run Peavey IPR's. I have one 5000. I just was not sure about running 3, 8ohm cabs on one side as I plan to build 4 more cabs.
