What is speaker beaming?
There are many different speaker designs and the way they perform is greatly affected by the space in which they are used. Bass frequencies are much more reflective than higher treble frequencies due to the longer wavelengths. This enables bass frequencies to "fill a space" better. Since treble frequencies (shorter wavelengths) are less reflective they tend to be more directional. Guitar speakers are more directional and prone to speaker beaming because their higher frequencies are mostly generated by the center cone section as explained in this article by Troels Gravessen. ToneShield counteracts the directional nature of the higher frequencies by reflecting them in multiple directions just after they leave the speaker!
What kind of amps and speaker cabinets can I use ToneShield with?
ToneShield is designed to work with one speaker that is relatively close to the surface on which the ToneShield base sits. A typical setup is to have the amp or speaker cabinet (single speaker) on the floor with the ToneShield base against the amp's front in the center of the speaker. Moving the ToneShield base away from the front of the amp may give a more desirable affect depending on the space. Please remember, the room or space is a major factor in how a speaker will sound and due to this ToneShield's affect will vary.
What if my amp has more than one speaker?
ToneShield can only work on one speaker at a time. It is possible to have 2 ToneShields setup side by side for amps and cabs with 2 speakers. Regarding four speaker amps and cabs - ToneShield will work on the speakers closest to the floor but not the upper ones!
What if my amp has wheels?
ToneShield will still be effective even if your amp or speaker cabinet is elevated due to wheels. It was tested to be effective on a Mesa LoneStar amp with wheels that elevated the amp approx 4". A ToneShield base design that will accommodate elevated amplifiers and speaker cabinets is in the works.
What if my amp is in a road case?
It is possible to use ToneShield with an amp or speaker cabinet that is housed in a road case but this will require a different base design. Please contact us and we can design a base to fit your situation.
Why is the ToneShield Base made of wood?
There was much to consider when designing the base and we finally settled on wood for many reasons - Wood is lightweight, It's renewable, It's easy to repair it feels nice and most importantly - guitars are made of wood!
Is ToneShield available with different color screws?
ToneShield is currently only available with brass screws but in the near future (depending upon demand) the screws will be available in other materials and colors. If you are the industrious type, you could also change them yourself with any 3mm x .5 x 5mm (Diameter x Thread Pitch x Length) flat head screw you desire!
How does ToneShield come packaged?
ToneShield is packaged with the protective film left on the panels and stowed in it's base. It is then put into a cloth bag which is then sealed in a heavy duty congregated carton. The cloth bag can be used for many things including storing your ToneShield!
How is ToneShield "Repairable"?
All of the panels are attached to the hinges using 3mm screws that are easily removable with a 2mm Allen (hex) wrench. You only need to remove 5 or 10 screws (depending on the panel) to change a panel or hinge. There will be panels, hinges and bases available for individual purchase in the near future. Repairing will be a rare occasion as the panels and hinges are very tough and resistant to damage.
