PEERLESS XLS10

[ruferto]

Hello,

Can I make an TH with Peerless xls10?
Is it any good for 90% music 10% Video

Best regards,

Hi,

Is this the right model number: 830500?

[ruferto]

sorry, it´s this one type 830452 8Ohm,

http://www.madisound.com/pdf/peerless/830452.pdf

Is going to be a complemente for my totem arro, i have made one 90hz HP filter for the totems.
now i want some impact that this totem´s don´t have.

Totem+sub.

best regards,
Ruf

The peerless XLS 10 is a ten inch driver, it might be the 830452 model he has? i have a couple of them. I think they are designed for use in a small enclosure, with a passive radiator.

 

[ruferto]

yes... is it any good for music?
I´am afraid that i made a mistake and bought a sub to listen only Mr Oizo - flat beat´s -

830452 Peerless 10" XLS

Hi,

Looks like it was designed for ported enclosures w/ a passive radiator 830451, but could also be usable sealed in automotive applications. It seems to model as a tapped horn just fine. Fire up Hornresp, and try to find a tapped horn size/frequency extension combination you like.

For nice workup see: Peerless XLS10 10" Subwoofer (830452) and Passive Radiator (830481) (not a tapped horn).

I built a sub with that driver and one matching passive radiator carrying 400 grams. If you need a lot of volume, two passive radiators of 265 grams a piece would probably be better. The matching passive radiators are getting hard to find. I think Peerless discontinued them.

It would never occur to me to use it in a horn. The Qts is extremely low. But what do I know about horns?

I'd build them into a tapped horn. Build the layout like the TH-SPUD. Hitting over 120dB with a 150 liter box is pretty cool.

Hitting loud enough in a 26 liter box is what I found pretty cool. And it's flat to 20 Hz in both rooms where I've used it.

Here's the sub (with matching empty box) before I upgraded the mains to Jordan Jx92s's.

Dave,

I didn´t want to spend more money but i think i have to
The sub is any good for Music with the xlspassive, from classic,acoustic to tecno, i just want some impact.
Is It HIFI or OIZO sub ?
I think i dont need lots of db´s because the totem´s dont go loud.

The TH sub´s are they more musical ? ?

Dave,

The TH sub´s are they more musical ? ?



RUF

Yes, and much lower distortion at a given SPL level than what can be done with sealed or ported box.

 

[ruferto]

JLH,
It´s my fist sim.
what do you think ?

 

[Homeboydeluxe]

120db from a 150Lt horn, thats brilliant! why is it so much smaller then other designs that utilize dual 8"s or dual 10"s?

I'll be following this build tread with great interest, if it works out i'll definitely copy it!

Would the drivers not be wired is parallel, 16 ohm seems pretty high for most amps?

 

[ruferto]

the problem is that, i only have one xls10

 

[JLH]

That woofer is 4 ohms, so in my model I have them wired in series. You can still build a tapped horn with a single woofer. I just like the additional even order distortion cancelation of running push-pull woofers.

I would not design a tapped horn with this woofer that is tuned below 30Hz. It is pointless. You will quickly run up on excursion limits and honestly with room gain 30Hz is plenty low enough.

 

[ruferto]

sometimes i want to see some movies. 30hz is it enough? can it put a tiranossauros rex beside me.

 

[Homeboydeluxe]

There is more and more 10-20Hz content in movies today, with a 30Hz tune you would be missing out IMO, those T-Rex stomps are in the subsonic range, you need a lot of displacement to reproduce them with any real authority.

SPUD like enclosure

Hi,

One of the things I noticed reading through the link in Post #6 is that the author went through the trouble of breaking the driver in, and taking multiple T/S parameter measurements. There is a marked difference between the manufacturers Le=4.3mH and the measured Le=0.79mH (after 50hrs), and it does make a difference in modeling tapped horns.

Just for an exercise I modeled two 830452s in a tapped horn with the general dimensions of the TH-SPUD adjusted for the 10-1/2" driver OD. The SPL response is actually quite similar to the response of the SPUD (or the DTS-10). This seems to be the HT loudspeaker style that Danley has settled on for the time being (see also: DTS-10).

If you already have the drivers, and if the box is not way too big, it would be a shame not give this a try. The thing to remember is the box size: 45"x48"x12.5".

Yes, Le has a big effect on tapped horn design. The nice thing about woofers that have a higher Le, its like getting your series inductor for free. Le measurements can be all over the place. The frequency it is measured at makes a big difference. What I've found in the past is Peerless tends to be one of the more accurate companies with specs, so I have no reason to doubt them. However, this doesn't mean that 0.8mH isn't the more accurate measurement. I gues you have to build it and see how it measures.
