Default Revelator vs Excel magnesium

Helo everyone, my Room is very smal and i have a diy vented speaker monitor with Scan Speak 18W paper/carbon. A have problems to control the bass, so I want to buil a 2 way monitor vented speaker about 10L to 15L with a smoller woofer.
I have Scan Speak 9300 tweeter and for the Woofer my choice is Scan Speak 15W/8530K00 or Seas Excel W15CY001.
I know magnesium driver have a break-up mode. No problem to control them with notch.
Someone know this 2 drivers?
Please give me your opinion.
Wich do you like best?
Can you help me?

Tanks

You have problems with bass modes so you are going to a smaller woofer to...reduce the bass? Is your ScanSpeak 18W speaker ported? Try stuffing the port (a sock will do, if nothing else).

If you insist on designing a new speaker around a smaller woofer, I really would choose a ScanSpeak 15W over the Seas. The lack of breakup in the ScanSpeak makes it very easy to design for. The Seas driver should be crossed rather low in frequency for it's size, around 2kHz if possible.

See measurements here.

I have paired the SS 15W/8530K00 with the Hiquphon OW-1 tweeter and love them both.

Yes, i have bass modes.

My room is just 2,7m x3,7m.
I have build bass traps, and just reduce modes.
Reduce port help too.
Transform speaker to closed help a lot, but lack dinamic.

But i listen in my room ported speakers with smoller woofer (like SF concertino) with good control bass, fast, articulated and impact.

So i think i have enough bass with w15 woofer.

Thanks

SS have sweet sounding,pleasureable,the low and mid low are deep,slightly thick in vocal ,a bit dark but enjoyable.
excel have transparant sound,very good clarity and detail,tight bass & mid low (not deep like SS).both of them are excellent driver

cheers

hmm......the breakup mode is a mechanical thing, wheras the notch fillter is completely electrical......
the old Seas datasheets suggest that there is a good deal (but perhaps theoretically unhearable) level of third harmonic distortion at 1/3 the f of the breakup mode.....

I've listened to 18W magnesium Excels, and 15W revelators -- I prefer the SS revelators.

So until now:
Scan Speak Revelator - 3
Seas Excel Magesium - 1




Based on your posts, SS rev. is more musical and warm and Seas mag. more detailed and cold. Im right?



More opinions plese

I've listened to two speakers at the same occasion which were reasonably well designed and flat on axis. One had 2x W15 and one had the Rev 5".

The Excel based speaker was cleaner, more musical and subjectively a better and more correct speaker.

So, +1 for Excel! :-)
