DT25 - Does anyone else find the speaker very directional?
by Stueyd on 2013-01-10 06:03:10

Like the title says....

I love the sounds I get out of my DT25 but it's really noticeable when cranked up to near gig volumes at rehearsal the the sound seems to come out very, err, focused in a straight line with not a lot of dispersal.

ie: The amp tends to get pointed at my keyboard player on the other side of the room who gets deafened but everyone else a few feet or so either side from the "tunnel of sound" says it's too quiet.

It's not just the keyboard player being funny, if I go walkabout to the other side of the room I can hear exactly what he means. Standing in the direct line of the speaker is a LOT louder than a few feet either side.

Anybody else noticed this? Certainly the sound doesn't spread out as much as it did from my old Marshall 1974X.

Other than adding expansion cabs, does anyone have any suggestions? I don't really want to have to put guitar through the PA for the small venues we do.

Hello.

You must try one of these diffusor:

I">http://www.musiciansfriend.com/accessories/weber-speakers-beam-blocker-high-frequency-diffuser">http://www.musiciansfriend.com/accessories/weber-speakers-beam-blocker-high-frequency-diffuser

Ihas the same problem on many amps (normally 1x12" cabs or ampls) , and this solution is very good for me. It not low the high frecuency of the sound, but it diffuses the unpleasant "flow" of highs in front of the speaker, and mix with all the sound of the guitar in the room, making the sound very pleasant.

If you think that is very expensive for only a piece of paper (me too)   , you can use the central dome of any speaker if you want, glue it to a rectangular piece of thick paper, and put the convex part of the dome looking to the speaker. It is exactly the same that weber solution

+1...Weber rocks...

Or do what old metal heads did and put an X with duct tape over the center of the speaker...

Yes, conic speakers are in general. I have used the Weber dispersion device with other amps and the work well, but if you want to mic it straight on I wouldn't bother.

I tried a variation of this at rehearsal last night.

I scoured the house looking for something vaguely resembling the Webers cone and eventually found a toy plastic burger bun in my daughters play shop. :-)

I "borrowed" this and gaffer taped it over the center of the speaker and bloody hell... It works!

It doesn't look very pretty, but all the band agreed the sound is far better now and as far as i'm concerned it does the job and sounds great.

My daughter won't be getting her burger back :-D

My daughter got her burger back :-)

Despite working so well, the gaffer tape and plastic burger bun solution just looked a bit naff, so I spent the money for a proper diffuser and got a Tayden one (http://www.lean-business.co.uk/eshop/tayden-sonic-diffuser-for-12-guitar-speakers-p-508.html)">http://www.lean-business.co.uk/eshop/tayden-sonic-diffuser-for-12-guitar-speakers-p-508.html">http://www.lean-business.co.uk/eshop/tayden-sonic-diffuser-for-12-guitar-speakers-p-508.html)as no-one seems to sell the Weber in the UK.

Jeez.... What a pain to fit it.

Not a problem with the diffuser, just that there's so little space in the back of the DT25.

I ended up having to remove the valves and unbolt the transfomer to get enough room to get the diffuser under the speaker and all the time because of the speaker magnet it was trying to attach itself to anything metal.

Getting the transformer back on was a pain because the nuts inside the actual encased amp part are not captive, so you have to open up the amp casing and again there's not a lot of room in there. There were a few other odds and sods of pain too boring to detail and I must have struggled for an hour and a half to get it all sorted and back together again.

Looks and sounds great now, but wow, a lot of effort....

After experiencing the "ice pick laser beam", I just put a Weber Beam Blocker into my DT25-112 Cab .... works great. I am sold on these things.

Did you buy the 4 or 5 inch version? Just curious on how much of a difference there is. I wonder if anyone has tried the jay mitchell foam doughnut on the DT25 cabinet.

In case anyone's interested... I now have a "beam blocker" AND a Dr. Z Airbrake Lite Attenuator installed in my DT25..

Wow! These 2 things are ESSENTIAL.

The beam blocker spreads the sounds out and the attenuator allows me to leave the amp cranked up high without deafening volume (unless required).

I thought this amp was good before, but with the valves really cooking it takes it to a different level.

I've fallen in love with this amp all over again.

Good to hear Stueyd.  I've ordered the 4" Beam Blocker and look forward to the change.  I'm hoping the highs will not only be reduced straight on but more importanlt will also be improved off axis.  Pretty hard to know how to set tones when it's sooo dependent on where sit.

So, if I have the DT25 1x12 combo, should I be getting the Weber 4" or 5" dome?  Thanks, guys!

I just installed a 4" Beam Blocker in my DT-25 112 and the difference is just short of amazing.  I don't know what a 5" would do but I'm very pleased with my choice. Obviously, the amp is still louder when directly in front of it, but the redirection of highs to the sides, and all around, is much closer to now what's directly in front.  I might even hazard to say it's louder to the sides now as well, though it could just be a psychoacoustic effect since the highs are distributed better.  Anyway, Weber designed themselves a neat little device.  Well worth the cost and it was easy to install.  No rattles yet, like I hear from some other users.  Time will tell but right now I'm a much happier camper about this amp.
