Midrange selection: Dayton RS52 vs. Peerless HDS 832873

gripracer · 9th July 2009, 04:36 PM

I am trying to decide on a midrange for my 3-way loudspeaker. It will consist of:

-Vifa D26NC55 tweeter (sealed)

-undecided midrange (sealed)

-Dayton Reference woofer, 8" or possibly 10" (bass reflex)

-200hz/4000hz LR2 crossover

The thing is, the Peerless HDS has an excellent response curve, staying within about 2dB from 100-7000hz. That nice high response lets me safely use a LR2 at 4000hz. Also, the HDS has great power handling, upwards of 100w RMS.

However, the Dayton RS52 also has great, flat response.

I am wondering if there would be any advantage in sound quality to go with a dome midrange over a cone midrange?

thank you!

Since your crossing at 200Hz you would need drastic solutions for the LF fund. resonance of the Dayton RS52. IMO Even if crossing higher at 300-400 it would still be a concern.

Dayton RS52AN-8 Fs=383 Hz I would not cross any lower than 1.5*Fs

With those crossover frequencies you might try the better 3" woofers like the Dayton RS100-4 or Fountek FR88

Maybe a small Peerless Nomex for mid

A mid dome will as said not work that low
Its is better for maybe around 1khz and 5-10khz
btw, theres also some Hivi mid domes, and TB

OK, lets say I change my midrange crossover point to 800hz.

The RS52 is superior to any cone mid?

I really like dome midranges they sound different to be sure than most heavier cone midranges that I've heard. Dome mids sound to my ears a little more delicate and sweeter (soft treated mid domes). Here is a 3 way project that uses them and the crossover can be tweaked to use dual 8". The crossover is close to your target crossover points ( 2nd order at 850 and 4th order at 3500) The designer uses high order upper crossover to tame the RS52 HF resonance (metal dome mid).

Ever tried to let a soft 2" mid dome run high up where it rolls of by itself?
The tweeter would just be supertweeter

It's certainly inferior to an exceedingly small number of them. Unfortunately, it can't be used as a dipole.

No have you, don't they have beaming issues up high, leading to offaxis issues in crossing to a normal flange dome? Maybe working it with a horn loaded tweeter could work out ok.

Tweeters have beaming issues as well
