Sub with peerless sls-10

[testarossa2k]

but this woofer is it good for the job? But I think it isn't for car
also on the peerless site it is not listed in automotive.

ok sealed. I think if I don't go for 93L I go with "application data" from peerless.

testarossa2k :



I don’t think your software correctly can model a damped vent/damped ported box.

yes it can model a damped box. But not a damped vent.

yes the cone excursion should be linear. But in the program it isn't stated

Before I didn't use the correct parameter. I use the ones on lautsprechershop instead of the PDF data from peerless.

thank you for your graph Bjorno.

So now I need a plate amp. here's the choice:

Here my main speaker:

They're vented

I posted since now I must choose an amplifier with 18db or 24db lowpass filter.

Power: around 100W at 8ohm.

Is it better to use highpass filter for the satellite or make them naturally rolloff in my case?

thank you.

A very quick look at those links, it appears you bookshelves play quite alright down to around 100Hz - I'd be looking at a sub that can play well lower than 70Hz, you're using the sub for just 70-100Hz??

If the power levels are too high for the bookshelves to cope with 100Hz then fair enough, cross at 120Hz or so, but if not I'd try and utilise them more and look at a different sub.

Don't let the satellites roll off on the low end, you stated they're ported so it's definately not something you want to do IMO. Do those plate amps you linked to have a built-in high pass? I'm sure they do as the have RCA in AND out, but it doesn't state what freq (sometimes they have a fixed high-pass of say 100Hz, and a variable low pass, which is sort of stupid because if you're using the high-pass feature you'll have to leave the low-pass at 100Hz).
