They are QSL audio ... PA use ...
I don't know .. i need a cabinet design for those , a deep bass subwoofer maybe .. or a horn .. i don't know .. so i let you tell your opinion ...


Thanks...

With an Xmax of only 1.75mm, these would only be suitable for mid range use. Even horn loaded they would not go very low before exceeding this small Xmax figure.

Look for something more in the region of 8mm or more.

You're right ... what driver you recomand me in what cabinet ?

A quick look at Parts Express shows 297-616 Peerless 831727 10" and 297-618 Peerless 831857 as being good value candidates for reflex type sub.

For sub use, a horn even with compromises requires at least a 2.5m path length regardless of mouth size, resulting in a box exceeding 300litres in size. The above speakers would probably not be real good for horn use - I would recommend something with higher Fs and large diameter voice coil to stabilise the cone under high pressure, and such a driver would most likely be more expensive than these, but overall performance would be superior.

So it depends a lot on your usage requirements, space limitations and budget.

Cheers

Try Fostex FW405 15" from Madisound.com, JBL 2225, BD 15 from http://www.diy-systems.com/ or Eminence 15" . Also search archives in this forum. Most of these are 96 dB efficiency, Peerless doesn't achieve this.

The Eminence HL10a is perfect for a horn-loaded sub for very high power home applications and for pro-sound usage. Where large cabinet size is not tolerable and SPL requirements more modest the MCM 55-2421 works very well, as can be seen in this chart:
