i am looking into making a sub to compliment my first set of Design build construct 2 ways!
I do not want to spend alot of money and the drivers needed to be readily available to me. (leaves me with Wilmslow and Falcon?)
I have had a many a late night with win ISD plotting different combinations etc.
I can get good curves (I take it we are after a smooth negative exponential curve) the -3db point being about 36Hz when used in a vented enclosure. The peerless driver and Morel seem to perform very closley in this configuration, now simulation is all well and good, but what will they sound like 😕
I am after peoples opinions and experiences of using either driver or is there a driver which for around £50-60 UKP i can't do without???

Ok i have ordered the peerless driver following a thread i found which mentioned how good peerless are for woofer drivers (cost considerations taken into acount!!)
The plot shows below the Peerless driver and the response of my Woofer in the 2ways.
i would be interested in any comments, the enclosure is 50 liters and is tuned to 25Hz
Also as the sides are likely to be of a quite large CSA howdo i go about bracing (front to back side to side??)

Hi Chuck,
Bracing in cabinets is usually used to stiffen the box and eliminate resonances caused by the walls oscillating out of phase with the driver.
In subs, this is not usually so much of a problem as the wavelengths are much greater than the dimensions of the box, instead you just have to deal with pressure variations caused by the driver's motion.
For a 50 litre box, this will not be much of a problem, provided you use reasonably thick material, at least 18mm mdf, preferably 25mm.
If you want to use bracing, I would suggest putting an extra panel, with big holes cut out, parallel to the front and back.
I assume you are using a ported enclosure, if so, the thing to bear in mind is that the port should be as wide as possible, to avoid noise due to turbulence. You also need to add the volume of the port to the calculated volume of your box to get the final volume.
Good luck🙂

Thanx, I am nearing completion of the enclosure, made from 25mm MDF, will omit the bracing as box has been glued and screwed with plasterboard screws at 3" intervals.
For amplification i am looking at the BK electrics stuff, probably the control panel and amp seperate rather than the plate option, Out of interest i contacted parts express - Shipping from for Plate Amp was $70
to the UK
