Installed/mounted the Klipsch driver today, and my first impressions are that it's much cleaner/dynamic sounding... :-) Also I'm not sure if it's just because it's new or if it's just a much stronger spider/coil, but it felt much tighter (pressing the cone inwards before mounting)... :-) Does anyone know if these drivers use neodymium magnet...? The reason for asking is the magnet didn't look very large, but it sounds tight anyway... :-)

I already am... Big time... ;-) I've been listening to various music (ranging from classical over soft pop to hard rock and dub step), and it's *almost* there... ;-) I'll receive the K-1072-A woofer on wednesday and try it out... If it sounds better I'll go with that and if not I'll look for something else (like the Monacor SP-380TC)... :-)

I ended up with a ~260 L enclosure (driver AND 4.3" port firing down) tuned to 20Hz... :-) I goes reaaaally low... And it doesn't sound boomy at all... ;-) Looking forward to trying the enclosure with the Klipsch driver. If it doesn't sound well I might end up with a driver that can "fill" the enclosure a bit better... ;-) The enclosure is built using MDF (19mm) with 2 "window frame" braces between the sides of it... They are not placed symmetrically... :-) I haven't put any damping in the enclosure but I think I might put egg-crate foam on the top panel (opposite of the driver)... :-)

Thanks for the answers... ;-)

I'm going to be using the sub both for movies and for music... :-) And I know it's not an easy task, but it's fun... :-) Still using the Monacor driver, I replaced the 6.5cm port with the 11cm (full length 19.5cm) conical yesterday and the bass is much more "hidden" now (less boomy). Just really low and tight (great for music)... ;-) The box should be tuned to about 33 Hz now. I've checked using WinISD (though with a port diameter of 10.2 - 11cm isn't available), and 33-34Hz seems to be the best frequency (flatter curve), but I get - 3dB @ 41Hz... Isn't that way to early for a driver with a Fs of 23Hz...? Vent Mach should be around 0,10 with the big port compared to 0,24 with the original one which is probably why it sounds much more clean now...? When building the new sub (with the Klipsch driver) I was planning to build it with the same dimensions as the KSW-15 using the conical 11cm port, and if it doesn't sound the way I want it to sound I'll try to decrease the length of the port... If it gets to short it's not very expensive to replace... ;-) Would You recommend me to build a larger enclosure for the Klipsch than the KSW-15 (using either the 6.5 cm adjustable port or the conical 11 cm port)...?

I would guess it's Denmark...Welcome to the forums! Bruce Thanks... ;-) Yes, I'm from Denmark... Forgot to answer that question... ;-)

Hi Fizzle... ;-) Thanks for the reply... And warm welcome... :-) I can get the driver for 500 DKR (~90$). I'm not sure I can get better drivers for that amount of money... ;-) Anyway, I'd like to try with this driver as a project (I'll probably build a lot more afterwards - I believe that's how it normally goes when You're a noob in sub building)... :-) I have an existing ported enclosure about 120L. The first thing I will do is replace the 6.5cm port (way too small even for the Monacor SP-380P PA unit which is currently used) with a conical 9/11 cm port (7.8cm long). When the Klipsch woofer arrives I will just replace the Monacor with it, but sooner or later I will be building a new enclosure in oak because I can get the wood for free... ;-) I was thinking I would just build it the same size as the KSW-15, but if You're saying that bigger is better I certainly don't mind building the new enclosure even bigger... :-)

I have been offered a K-1072-A woofer driver (brand new) and was thinking about building a subwoofer using the unit. I will be building the sub in oak and it will be powered by a 300W BASH amp (O-Audio). The driver looks exactly like the one used in the KSW-15 (K-1072-K). I found a picture here: http://www.ebay.com/itm/Klipsch-KSW-15-Home-Theater-15-Subwoofer-Black-/220784684970?pt=Speakers_Subwoofers Would it be possible to get the specifications for the driver or will I have to build it exactly like the original enclosure? If it's not possible to get the specs for the unit, can anyone please give me the details of their KSW-15 (dimensions of enclosure + port).
