The tone woods used for my cabinets are various in selection.Exotic & north american solid/hardwoods.Woods are not and cannot be haphazardly chosen.We insure that all woods have been run through the proper drying process so they will not warp or crack.Wood timbres and different species of woods all have their own tonal characteristics and we try to insure that they are coupled perfectly for world class tone.You might have noticed the flat or lifeless sound coming from your speaker cabinet?Well this is due to the fact that the manufacturer who made your cabinet used plywood and/or particle board.This wood was used simply because it is cheap.The only "good" thing about this wood is that it is very stable and will not alter it's shape under weather,humidity or temperature change.But it is that stability that is one of the main reasons why your cabinet sounds undesireable,characterless and toneless.Just as in your guitar,violin,bass,drum shells or concert piano the woods you choose for your instrument are imminently vital to the tone,character,life and presentation.Solid and hardwoods allow much more resonance and presence to be brought to the life of your instrument.The same is true for speaker cabinets. The standard Marine grade baltic birch "void" free 7-13 ply plywood is used by almost all cabinet makers and i can use this wood if requested since i do aspire to make custom cabinets per customer.But Simmons Cabinets was designed with SOLID WOOD TONE in mind.So the use of solid poplar and solid red oak is standard in all Simmons 2/10 and 2/12 cabinets.All solid poplar and red oak is 11 & 3/4 wide and 3/4 thick.Solid wood presents solid tone 100% of the time "you wouldnt play a plywood guitar would you?"All woods are "Tone Tapped" for likeness & sound similarity prior to assembly and for proper cabinet placement.Other woods used and highly reccomended is MDF board.MDF is a medium density fiber board and is standard in almost all of todays cabinet enclosures.JBL,Behringer and Genz-Benz respectively.Contrary to some beliefs MDF board is not as frail and fragile as particle board.MDF holds screws better and does not chip away and crack when using the cabinet in heavy amounts of overdrive.MDF board delivers a truly sonic and honest representation of your speaker configuration in use and with an un-altered soundwave is a non-biased audio response.MDF is the most void free wood available in the world and we highly reccomend this for any speaker cabinet for any style of music or instrument.We painstakingly analyze every detail and we meticiously listen to our cabinets and the knowledge we recieve we use to post-engineer the speakers and tone woods housing properties to deliver trademark sound and quality. White oak void free 7-11 ply is also available.As is White birch @ 1/2 ,5/8 and 3/4 of an inch thick.MDF fiber core 2 ply with 3 ply baltic birch center and top and back veneer is available also in sizes stated.The tone woods are for you to choose from so take your pick.I can combine all woods mentioned into one cabinet.Birch baffle boards are reccomended for resonation quality and speaker mounting strength.I will not and refuse to use particle board!!! Other available tone woods are as follows :MDF with white birch veneer.Solid poplar fibercore with white oak veneer.Pine plywood with white birch veneer (think '59 Fender Bassman tone) I would not reccomend this particular wood for anything more than a 1 or 2 speaker configuration since pine plywood can be very "nasaly and overly resonant" when pushed too hard at high volumes via multiple speakers.But in a 2/10,2/12 or 1/15 it sounds bell like with thick mids.Solid pine on the other hand has a very unique and harmonic upper mid that is very distinguishable and noticable.A very friendly and easy to play sound that fits in the right place of your overall sound.The grades of wood i use allow little to no defects or voids as i stated earlier.No large knots like you see on boards or lumber from home stores or lumber yards.Please see TONE WOODS pics.
