Seas ER15RLY vs. Peerless HDS Nomex (830873)

Dag · 19th November 2007, 11:49 AM

Seas ER15RLY and Peerless HDS Nomex (830873) are both very good midwoofers and measures well. http://www.zaphaudio.com/5.5test/
(Thank you Zaph for your fantastic page!!!!)

But which one do you prefere??
I want to use one of them in a 2,5 way with active 4th order LR at ~3000k.

Tweeter will probably be Vifa XT19 or maybe Seas 19TFF1.

Hi,

On paper the Peerless is more suitable for a 2.5 way due to its response.

Are you sure you dont mean the Seas ?

sreten · 19th November 2007, 05:11 PM

No. I meant the Peerless. A 0.5 way has 6dB of BSC by default. Work out the rest yourself .......

Thanks for the responce, right now it´s 50/50!

Since I'm going to use a an active filter I can adjust the LF responce if I want but I think the extra bass from the "0.5" will be enough (as sreten also wrote)
Since I haven't heard any of them I would be very happy to get some comments from someone who has!

Well, it is true in a passive speaker with a parallel 0,5.

Not exactly what you asked but to me the graphs look better on the Peerless. A little less distortion and flatter response graph then the SEAS.

Any comments are welcome!

I agree about the distortion and FR....but how about the CSD?
And does thease measurements tell us all about the sound??

Ok, not to start a flaming war in here but according to some, CSD doesn't show anything more then the THD and FR graphs already do. Just a different way of looking at the same data. I stopped looking at them completely but that is just me. It's also been said that once your x-over is installed, it will make both CSD graphs look similar, so I pay more attention to THD.

What I would be curious about is the difference in X-max. Granted in a MTM speaker x-max is less of an issue because you have double the woofers but 3.5mm to 5.0mmm is a big difference. Can anyone comment on that?

Dag · 19th November 2007, 06:15 PM

Just to add to the war

THD and FR tells you little about the transient responce. Maybe if you add the phase responce that will be enough........

The difference in X-max is interesting....but peerless has lower LF THD at the level Zaph measured. Also, is larger X-max always good or does it effect the midrange? (http://www.zaphaudio.com/lowxmax.html)
