dcnicholls Posted March 4, 2018 Share Posted March 4, 2018 I have two pairs of PCL15s (different parts of the house). Both superb. Does anyone know about a sub-woofer made by Duntech around 1990? Link to comment Share on other sites More sharing options...

They gobbled 200 watters easily.. Link to comment Share on other sites More sharing options...

I also have a pair of PCL 5s that I am not using but are earmarked for my son. 3 Link to comment Share on other sites More sharing options...
930turbo Posted March 20, 2018 Share Posted March 20, 2018 Hi guys , Sorry to revive an old thread and discovered it this week . I still have a Duntech Princess C5000 . I’m in love w/ them . Been driving them w/ audio research power amps. At first a D250MK 2 Servo then a Classic 150 monoblocks . And I think the Princess have found her match my REF 610T monoblocks . 11 Link to comment Share on other sites More sharing options...
brumby Posted March 20, 2018 Share Posted March 20, 2018 Here's a pair of Duntech Viceroys I ran with an ME 550 Hi Cap/24 combo for about a decade. This shot was taken, I think, in 2003. I had lusted after a pair of Marquis for years. I got these from Tony Mills in the Gabba (Brissie) for a very good price sometime in the 1990s. 4 Link to comment Share on other sites More sharing options...

logean55 Posted March 26, 2018 Share Posted March 26, 2018 yay they were easier to get right in context of a overall system....ditto on the effects of the size to the expections of the usually uninitiated they expected overwhelming bass LOL ....what they did have is what i call a "Wave Front" that came through in the better recordings played..... my words for lack of a better description that was convincing and not always asociated with volume..... anyway......most still aspired to the Soveriegn......

What do you run the BN's with? Hi frednork. I have two Kenwood L07 monoblocks which connect to the speakers with their specially designed very short leads (30cm). With "high speed amp" design and high damping factor they grab and control the BKs well. They have the supplied Kenwood very long signal leads (10 metre) running to them from a Yamaha home theatre receiver RXV-650. The Kenwoods are virtually satin black and sit inconspicuously on the floor alongside the big Dunnies. I step up on them to dust the piano-black tops of the Dunnies (I jest). For surrounds I have Duntech PCL-3's. Centre speaker is a Kef iQ6C with dual concentric driver and carefully distance/time aligned with the BKs. No subwoofer(s) needed or desired as the BKs would go down to ~20Hz -3deebs by my calculations with the help of the room loading. Unpublished graphs are as .pdfs.

DRC Posted March 27, 2018 Share Posted March 27, 2018 (edited) A pair of Barons in the 'office' system. I owned a pair of Viscount's many years ago and did miss them once sold. I'm trying to find the time to host a GTG in April, and will endeavour to bring a pair of Evolution One monoblocs from home to drive the Baron's with. The Halco MC series amp is good, but more current doesn't go astray... Edited March 27, 2018 by DRC 5 Link to comment Share on other sites More sharing options...

vur Posted April 5, 2018 Share Posted April 5, 2018 Re the appearance of the Black Knights and others using the black sox, I have always thought that mirrors up the sides would look cool in some rooms ..... something akin to the Gale 401's with their chrome ends. I happen to have a 2metre x 10cm strip of mirrored acrylic and placing it up the side certainly reduces the look of the sheer bulk but is nbg in my room as I have the BKs either side of a projector screen and reflections ruled the idea out. 1 Link to comment Share on other sites More sharing options...
t_mike Posted April 7, 2018 Share Posted April 7, 2018 Does anyone have cases for Sovereigns I can look at? Even some sort of blueprint would do. Yes, I'm having some very silly thoughts. Link to comment Share on other sites More sharing options...
vur Posted April 8, 2018 Share Posted April 8, 2018 ? By cases do you mean the delivery crates for them or do you mean the actual speaker enclosures? Do you plan to build one as a coffin that you can be buried in to pay homage to John Dunlavy? 1 Link to comment Share on other sites More sharing options...

Do you plan to build one as a coffin that you can be buried in to pay homage to John Dunlavy? Crates, for the purpose of transportation. I've never really thought of the enclosures as caskets before, they are certainly large enough, and if you're not dead yet, all the lead will fix that in short order. 1 Link to comment Share on other sites More sharing options...
Terence@33 Posted April 21, 2018 Share Posted April 21, 2018 Thanks for the Duntech material. I just bought a pair of Marquis. Very happy with them, but I now want to upgrade my amp. I've been told that the Marquis need a powerful amp. Do you know if this is true? Link to comment Share on other sites More sharing options...
dcnicholls Posted April 21, 2018 Share Posted April 21, 2018 They do like plenty of grunt. I drove mine with an ME850 power amp. Link to comment Share on other sites More sharing options...
