Thanks GPM , thats too bad , 310 cabinets !
Is there any member who has a 310 cabinet ? Would like some pictures . Also I am wondering if the horn should be wider with using a 21" speaker ? Is there any other threads on the A4 A3 A2 A1 210 211 or 310 , some more pictures to add to my Altec album would be nice .

Thats the best help Stephane . Thanks
Other than a 310 A1 or A3 that may be extinct there may be no better information . The last things for me to figure out is if I should make the horn opening greater than the stock 9 13/16" because I'm using one 21" speaker and how to alter the horn to get the 60 by 125 angles of distribution . Box size 74" h 27" w 47" d . Attachment 55276 The horn and speaker mount I need to build a little altered of course Attachment 55277 http://www.audioheritage.org/vbullet...ons/icon12.png

I've always loved the look of the A4
I only discovered the 1930s area Alec shearer about a week ago and I was so tempted to build it instead but I have been set on a A4 210 box for the longest time . My friend , a musician , told me he had a pair of A4s many years ago and every time he hooked them up the cops where called so I have confidence that mine will sound great . My plan is to sell of some my odd speakers and do lots more gigs to raise some money to buy another 21" speaker at 800+ dollars and build a Shearer box next and repeat the process . The Shearer was even shallower at 30" deep , I will make mine the same dimensions as my current project at 27"w74"h47"d and seal the rear center behind the speaker , it should give me even more deep bass , the Dubstep will sound and feel so good . Attachment 55280Attachment 55281 and my boxes are 4000 watts continuous verses the 18watt shearer .

Decisions ! You got me worried now , how well will my bass out put be with a 211 type box I'm building ? I have crossover EQS compressors and I can adjust the higher lows all I want . I am at a point where my end result can be a 211 or a Shearer , but I have no blue prints or good pictures of a Shearer and I want to get the box done today . I think my higher lows will be fine , I'm more concerned with how low I can go and how good the lows will sound . Do you or anyone have Shearer blue prints or pictures ?
