Hello all,
My first post, and I am UK based, so first a big hello to all.
So.... I would like to build a large subwoofer, this is to be used in a large poor acoustic/room around 80ft by 60ft with a suspended ceiling and some reflective surfaces, it is a large workshop within a large warehouse where my and a coleague have decided (and been allowed to) to put some kit together for movies. (Since having kids there were sacrifices for us both at our homes )
The speakers in this system are Cerwin Vega Mk1 V-152's with a sensitivity of 103db, and I feel they cut off around 40-50hz, we have tried a couple of small domestic AV subs and I feel such cannot match the main speakers. Amp is an ageing Yamaha A1 or such (huge with front flap)
This is on a budget, so I am thinking of a big driver and a subwoofer plate amp (or a bridged budget PA amp and passive crossover/filter), money is tight so good bang for buck, with the possibility of future upgrading may be beneficial.
I have been advised a Precision Devices PD-186 18" 97db sensitivity 4ohm 600w bass driver may be a good choice, and was thinking of adding a 500w (4ohm) subwoofer plate amp from Wilmslow Audio.
If the above driver and amp are good starting points, I guess the next step is what sort and size of enclosure? Any advice on these choices and my options?
I have plenty of cabinet materials, 1" chipboard, 18mm MDF, 2"+2" batton, screws and dampening, it will be fitted to castors and size is not really an issue in a large warehouse with double doors to the listening area. I guess a simple to construct large not too complex cabinet with cross bracing and no time spent on aesthetics may be in order.
What I would like is clean and even powerfull bass with decent LF extension around the 20Hz area, sensitive enough to provide a reasonable match to the 103db sensitivity Cerwin Vega's, and teh parts have to be easily to purchase within the UK.
I would also like to get this done before the end of the month as the current sub (a small Kef item) will probably die soon if my collegue has his way.
Any opinions or ideas on which direction a newbie should take?
On a side note, a couple of guys have offered me car audio sub woofers, one of them a 12" Fusion item in a large carpeted box with green trim, and some have said adding a plate amp to such may suffice?
Thanks,
Steve
