Fijn om te horen dat je subwoofer eindelijk tot zijn recht gaat komen, Erik.  Ben benieuwd hoe ie het doet tegenover mijn PB12-Ultra/2.  Ben zelf net bezig de accoustiek van mijn kamer grondig aan te pakken (die was heel slecht), dus ik ben in vrijwel dezelfde stemming aan het raken. :)

Mathijs...alvast bedankt voor het aanbod...ik wil er pas op ingaan...als mijn vrouw niet meer het idee heeft dat ik " bakken Euro's " (momenteel) naar buiten draag  ;D

Leuk dat het mensen inspireert!!!

Erik heb je misschien de foto's nog?
Zoja zou je ze dan opnieuw willen plaatsen?
Ben nu wel benieuwd na wat ik erover lees.

Kan je voor dat geld beter een Crown K2 kopen. Met een KSA-50 zal je toch op moeten passen dat je niet tegen de amp zijn limiet gaat staan te draaien!

Als eerste de conclusie: aha, daarom kon ik het topic niet vinden. Je bleek het niet zelf geopend te hebben ;)

En als tweede de vraag of het klopt dat je site offline is? Ik wilde even kijken wat er daar nog aan foto's in staat zodat ik die in de openingspost had kunnen neerzetten.

Dat het ding er machtig uitziet is 1 ding.

Hoe die klinkt ben ik eigenlijk nog meer benieuwd naar. Zeker omdat de vervanging niet echt "gepland" stond.

Maar een mooi ding is het zeker. Om te zien alvast :clapping:

Tja ik vind hem in een Hometheater configuratie gewoon (zoals door vele sub gebruikers al vaak getipt) een stuk beter dan de Focal.

Focal was een dure unit (ik denk rond de 700 euro) en deze minder dan de helft.....dus een nobrainer

De Dayton UM15-22 veegt echt de vloer aan met de Focal 15K8711 in even grote mate als dat de Crown K2 de vloer aanveegt  met de veel duurdere Krell KSA bakken..(in een Hometheater configuratie)..en ik weet waar ik over praat  want ik bezit het allemaal dus zeker geen napraten.

Het blijft gewoon moeilijk voor een High End Audiofiel om dit soort kreten op waarde te schatten.....totdat je het aan den lijve ondervind.

Enfin de moraal van het verhaal....een open mind wordt beloond  O0

Sorry guys maar even voor mijn eigen administratie mijn woofer gegevens noteren....
(En ja na het Ongaku-project ga ik de 18 inch versie erin zetten.......iedereen wist het al behalve ik  ;D)

Dayton Audio UM15-22 15" Ultimax DVC Subwoofer 2 ohms Per Coil

Over 1-1/2" of travel (3/4" Xmax) is kept completely linear through the use of dual spiders that also limit distortion and rocking modes. "Tall-boy" rubber surrounds with integrated gaskets maintain driver surface area during extreme excursion moments. Thick, one-piece Nomex honeycomb covered cones are covered with woven, heavy-duty glass fibers creating ultra-still cones that resist deformation.
A strong motor takes you to wherever you want to be
A large copper sleeve and copper pole cap in the motor reduce energy storage from inductance, with the side benefit of lowering distortion for "faster" response. Large dual-stacked, high-energy magnets handle the heavy lifting and bring Qts down to a level where Ultimax subwoofers can be used in vented or sealed cabinets and enclosures.

Cabinet recommendations:
• Sealed 3.1 cubic ft. (net internal) with 3 lbs. of Acousta-Stuf polyfill, f3 of 35 Hz with a 0.707 Qtc alignment
• Vented 6.0 cubic ft. (net internal, not including driver or port volume) with 6 lbs. of Acousta-Stuf tuned to 18 Hz with two 4" diameter by 26" long flared ports for an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.

Note: All parameters derived with voice coils wired in series.
