Tunning 4 rev10s with sd2 amp

[Bpike7]

how to tune 4 rev 10s to a sd2 amp, I also am running 4 in boats off of syn4. Help for both setups would be greatly appreciated. I am new to this so please bare with me. Thanks

Give me some time and I will post a pic of my settings on my amp for my 4 rev10s. I had scream marine tune them and they are frickin loud!

There will be some variable factors that determine the gain level and final tune like music source, head-unit pre-out, pre-amp EQ/line level. For the in-boats, if there is a sub in the system, they get tuned in together. The in-boat tune would be different if not sub is in the system. I like Hi-Pass for all full-range speakers. With the SD-2 driving tower speakers, i like mono.

here are some pics of the way mine is tuned and I know there will be variables like CHP said but can hopefully give you a starting point. The gauge of wire going to the Rev10s will probably play a part also but should get you close and you can tweak from there.

JLG,

Is that in stereo or mono ? Hard to tell in the pics.

Thanks

Sorry about bad pics I believe by looking at them on my phone its in stereo. I would have to take covers back off but that is what it looks like to me.

It look to be in full-pass and stereo. As noted above, I like hi-pass and mono, heres why. Although the rev-10 is a 10" woofer, its not a sub-woofer by any stretch. Its still a full-range speaker in the same sense that a 4" coax is. Woofer, tweeter and built in passive cross-over. When in full-pass, the freq filter is off, so the amp is driving the speaker with its full spectrum. This can over over drive the speaker, as well as it places more work load on the amp. Running hi-pass, filters out those frequencies we dont want or need a full-range speaker playing. By narrowing that bandwidth, the amp works harder and we can get more output from the entire setup. Running mono is beneficial for a surf setup. When off axis, like surfing and the speakers are in stereo, the listener is not hearing all the program material. probably about 75% of what they hear, is from the speaker closest to them. You wont hear stereo, because both speakers are basically to one side of the listener. With the amp running summed mono, both speakers play 100% of the program material.

Thanks for all the input, just now getting to it today

Mike, I just switched my tower configuration to power the Rev 10's with the SD6 putting 585 watts to each can, I am just getting to the tuning phase now. Do you recommend this set up with this configuration as well?

[chpthril]

Sure do. Hi-pass and summed mono.

I like how they are putting the adjustments on the front of the SD amps. Someone is thinking there. After crawling around under the dash, I wish mine had that.

My 2 cents worth - Tuning is all in the ear of the beholder. Yes there are a few rules to learn about high pass and low pass filters, or some tricks of the trade, but mostly you just try to balance speakers so they are the right volume, and it's up to you to decide what sounds good.

For me, I like to play my all my speakers as low as they can go comfortably, as that gives a more consistent sound.

I run my in-boats about 80-100Hz High Pass
Towers 60-80Hz High Pass
Subs- 80Hz low pass (mono)

As for gains, set them until you hear them evenly. Keep left right balance the same (for a boat). As for the tower, that is all personal preference. Most guys adjust it on the fly with a WS420 anyways.

Try to set your pre-amp gains higher and your amp gains lower (i.e. run a higher volume setting and a lower gain setting as that gives a cleaner pre-amp signal)

Set it up the way you like it. There really isn't a wrong way to do it.

Cool thanks for the input folks
