All Eminence OB

[Yunick]

not together ;

I did listened to SFR144 , SFR200-8 , SWR200-8A in various circumstances - in horn loading , and bare drivers ;

Which one would you consider best suited for use in OB paired with 1 Alpha-15? I will add maybe a second Alpha-15 later on..

also - I listened to MJK- style OB , with 2 Apha15 per side , paired with two ancient oval Iskra's per side .... pure joy

That sounds very promising
To bad those Iskra's are so hard to find where I live :-/

 

[Yunick]

...... good Lad

Thanks..

I hope you are little more informed now

Very much so Thanks alot for the fast reply's. I'll go ahead and order some spks today.

see enclosed pic - that's for SWR200-8A ( Bass reflex/Onken use , AlNiCo - my fave ) paired with 2 Alpha's . for my ears - that driver have best mid and top end of Sonidos ..... even if just slight differences are in question .



sim is with "standard" MJK 12/12db/oct xover , two Alpha's . two per side is a must ...... but you already know that they're dirt cheap for results ......
even if they are scarce in Serbia , when you can grab 'em for 55E/pc ....... that's bargain .

edit: any of these Sonido's are bargain , too ; they'll never be in last 5% of Lowther stellar hights , but important difference is that you can listen the music from 1 hour of their electric life , not like with Lowthers ...... pain and trouble in first 500Hrs , pain and trouble in making custom plugs ...... and price is in range of 300E/pair , delivered too your doors .
important - Mighty ZM is just a happy customer , nothing else ..... I'm boring even to my self with all that Sonido praise .....

Hi OB fans

What about Dayton audio IB385-8 15" Infinite Baffle Subwoofer

Power handling: 350 watts RMS/600 watts max
VCdia: 2"
Le: 3.08 mH
Znom: 8 ohm
Re: 5.2 ohms
Frequency range: 20-500 Hz
Magnet weight: 90 oz.
Fs: 20.8 Hz
SPL: 88.2 dB 1W/1m, 90.0 dB 2.83V/1m
Vas: 11.11 cu. ft.
Qms: 12.08
Qes: .69
Qts: .65
Xmax: 14.3 mm
Dimensions:
Overall Diameter: 15-1/8"
Cutout Diameter: 13-7/8"
Mounting Depth: 7-3/8"
Magnet Diameter: 6-1/2"

This driver might be a solution on lower octave mounted instead of second 15" and filtered/powered active.
Truly, I am not experienced with building and tunning OB, but this dayton seems almost perfect to get some tones below 50 hz.

yup ; why not ..... but active is a must , as you said ,and then everything is possible

Xmax is impressive

I could not find a model called SWR-200. Did you mean SFR-200 ?

.....considering that you're Papa with small kids

even if they don't have them online , all their drivers can be purchased either with ceramic or AlNiCo .

Hi Yunick!

Nice work!

I'm sure that the Zen Mod's proposal with two Alphas and a Sonido will be a hit. In the last years, we have come to the close agreement as to what works (and what does not work) in open baffles. I am still running a single Eminence Beta 15 paired with Visaton B200. I am still puzzled that you managed to get Beta 15 to work with only 1st order crossover ( I could not). At present, (still experimenting) I am crossing the Betas at 120 Hz 12 db/oct (Linkwitz-Riley), biamped and aided by Graham's T-bass circuit. Visaton is cut at approx. 300 hz 12 db/oct (Linkwitz-Riley).

I guess that with Alphas it will be much easier...

Also, for relatively narrow OB's, I have found that they sound better without side wings...

 

[Tea-Bag]

I like the Dual Alpha's myself, with Grahams circuit goes pretty strong till 40hz or so. Seems 'fast' and 'dynamic'

ZM, Did you get Sonidos to make to OB spec's?
I e-chatted with Zoltan, and says that can be made to spec for this.

I am thinking of course a Goldwood 18" with a Sonidos 145-A on a panel...

Здраво ЗМ - који желе да разумеју шта ја мислим? Понекад оно што ја мислим - и то је прилично глупо.

Hey - I did that via Google translate - so if it is messed up and has a buncha cuss words - or makes no sense at all................. well it most likely that GT messed it up. OTOH - maybe I don't make any sense in da 1st place!!!
