Was checking the Paradigm website today and I noticed that the specs have changed for the Reference Servo 15, amp power is now rated at 1200RMS as opposed to 400RMS before, and now the low frequency extension is listed as 10Hz as opposed to 17Hz before. I sent Paradigm an E-mail asking if this is a new revision of this sub, I'm awaiting an answer from them.


For the record, the specs of the Reference Servo 15 are now almost identical to the Signature Servo 15.

Those are the specs for V.2 of the Servo 15. Much longer excursion and heavier built driver, much greater amplifier power, greater output, and deeper extension. It is essentially the Signature Servo 15 in a simpler box with a much lower price. It looks like a sweet subwoofer.

 

[LEVESQUE]

The new specs are for the brand new Servo-15 v2. And the price is also higher for the v2 compared to the "old" v1.


There was some threads in here about this not long ago.

 

[Blkout]

Yea, just got off the phone with my local Paradigm dealer, he basically said the same thing, its the new v.2 Servo 15, and the price has almost doubled.


I just need to decide now whether or not to go with the v.2 Servo 15 or the SVS PB12-Plus/2.


Anyone have thoughts on this?

it was 14Hz not 17Hz low extenction on the v1.

OK? And that changes the fact that its now 10Hz, how?

Didn't realize you knew everything, when did the God position become available?

Boy, the GF must be on your case to change that existing sub.....glad I dont go thru that kinda crap.

Actually no, the GF approves of everything I do, I am looking at the Paradigm Servo because the new Servo specs are VERY impressive.


I'm sorry you don't have a GF.

 

[Yosh70]

Yea thanx but Im happily married.

I wonder if you recognize this quote....or was the GF typing this at the time?

I'm also using an SVS PC+ 20-39 sub, but am considering a Paradigm Servo 15. Not that the SVS sounds bad but the GF hates the look of the cylinder.

Just because she hates the look of the cyclinder has nothing do to with me getting rid of it, in fact she told me to keep it instead of spending more money for a Paradigm sub, I just like matching stuff, I'm funny that way. She has an opinion just like any other human being, its just that I have the final say so in everything around my house.

I've said this before, but let me repeat. There is no way that the bass extension can be 10 Hz. I just don't believe it - and I am a Paradigm fan/owner. The company is very reputable and so I don't understand why they publish such a thing. I'm sure that my belief will be verified once there are reputable reviews and measurements. I think I did see a review and measurement of the Signature Servo in a glossy mag. I may go look it up to see what they came up with.


Just so that nobody misunderstands me, I'm confident that the Servo-15 V2 is an outstanding sub that goes deep. But not down to 10 Hz.

Why wouldn't you believe it? A 15" subwoofer is easily capable of going that low. The reason why you don't see most subs go that low is that there is VERY little audio material that could make use of it, and sub output at that frequency would be minimal. Just because Paradigm claims the sub will go that low doesn't mean it has tons of output at that frequency.

It may take a huge amount of equalization to boost the response at really low frequencies, but that can and is done with all of those high powered small-box subwoofers.

I don't think so. Some day I'll have to calculate what kind of excursions you'd need, but it may need to be measured in feet, not inches. A few months back, Stereophile Ultimate A/V magazine (or whatever it is called now) had a detailed review and measurements of several very high end and robust subwoofers (it spanned over about 3 issues). Some of the subs were a $10,000 Genelec with multiple drivers and the size of a coffin, a ~$10,000 Wilson Audio, Velodyne ?? etc, etc... Basically subs don't come any bigger/better. The review looked at big bass content in movies. Lots in the low teens Hz and one that even went down to 7 Hz (helicopter blades). NONE of the subs coud reproduce 10 Hz. IIRC the most robust sub (the Genelec) petered out in the mid teens Hz.

I think most of the better ones only make it to about 20 Hz.

Once again, its not a matter of "IF" a sub can reproduce such frequencies, its a matter of total output at those frequenices. A sub can reproduce 20KHz if asked to.

Exactly. The servo-15 can reproduce 1 Hz if it wanted to... albeit at imperceptible levels. This is why _all_ subwoofer company excursion numbers should be taken with a grain of salt. The only true method to compare subs' excursions is to take measurements in the same room.
