Sub with peerless sls-10

testarossa2k · 16th August 2007, 01:16 PM

Hello,

Peerless sls-10
http://www.lautsprechershop.de/pdf/peerless/sls10.pdf

93 liter ported enclosure with 10cm diameter x 19,7 port, heavly filled with absorbing material. I will use it with two bookshelf speaker(72hz -3db) for music.

Is it a good enclosure for this driver? and most of all is a good driver?

thank you

You would be better telling us what frequency it's tuned to, it's too hard to guess from the port and box size.

I wouldn't heavily stuff a ported box, it prevents the port doing it's thing.

IMO it won't sound brilliant as your box is bigger than Vas and the driver has pretty high Qts.

It's not really suited to a vented box, Qts is too high.

The alignment you've suggested will give about a 1.5db peak centred on 50Hz, also you will only be able to feed it about 10w before it starts bottoming out.

84L sealed will give you a Q of 0.707, f3 in the mid 40's and much higher potential power handling

it's tuned to 30,91hz. I meand the box is heavy filled, while the port is slightly filled.

look

yes you have 1.4db peak but around 70/75hz so at the crossover frequency. and 1.7db peak at 50hz but all coud be reduced by slightly filling the port.

There's no problem for excursion at 80W it within the limit. And damping the driver basket I think lower the qts.

do you know a software for ripole design?

I can send you cabinet details along with filter data specifically for the SLS 12 Peerless.

testarossa2k · 16th August 2007, 06:20 PM

this is not a sub woofer, its just a woofer, sealed will give u a quick and tight responce, small size, i think ported enclosures are good only for freq. below 100hz (sub-woofers).

BTW are you planing to use any tweeter with this driver for high range, if yes wats the cuf-off freq. u planing to have
