How are you using your RL-p15?

**JorgenMan** · **10-11-06, 10:58 AM**

I'm curious how many people are using their RL-p15s in sealed, ported, IB, or other types of enclosures. Feel free to post specifics about yours, but I thought a poll would be a good way to get info from lots of people, since they wouldn't be forced to write a whole post.

There seem to be a lot of big ported enclosures, but I wonder if that's actually what most people are using, or if those people are the ones who tend to brag the most about their subwoofers.

Four RL-P15's in an IB manifold driven by an EP2500.... flat to 10Hz (can't measure below that with my equipment), measured 120db + at 15 feet... too scary to go beyond that

Darren,
That IB setup is nuts. I couldn't imagine putting that much in my attic. Does your house have a resonant frequency.

**Darren** · **10-11-06, 01:15 PM**

While my IB is quite impressive in output it is small in comparison to some

My setup will displace 16 liters of air, I think my house resonant frequency is somewhere around 12Hz if the walls moving are any indication!

I've got the same setup as Darren, but just haven't installed it yet. I'm waiting on cooler weather and the grass to stop growing so I can start the project.

Ported in a 56" sono tuned to ~16.7. But looking forward to a IB.

I'm presently using one of two as a footrest under my desk -

Dual SLLTs (Two RLp 15s on each side) two EP2500, flat and loud to 10Hz,

love it!!!

Wow, so you are powering four RL-p15s with only one EP2500 and getting that kind of responce? How many watts per sub is that?

You dont need that much power if going IB.

Im putting mine in a 260L sonotube tuned to 15.5hz....like everyone else.

**vitod** · **12-13-06, 08:20 AM**

This is not the best application, but for now they sound very good.

**Geoff St. Germain** · **02-01-07, 04:03 PM**

I'm building a ported enclosure for a single RL-P 15, but eventually I'd like to set up a IB sub.

**FlashJim** · **02-21-07, 10:55 AM**

Sealed at the moment. Ported next. After that, probably IB.

**Sonnie** · **03-02-07, 07:25 AM**

I guess I can chime in now... almost completed dual LLT.

**vitod** · **03-07-07, 11:54 AM**

Update: Built two rear ported 9cuft boxes tuned to 17hz using 6"X24" PVC port.

**JorgenMan** · **04-09-07, 03:20 PM**

I'm in the club now! Two in an IB.

**Geoff St. Germain** · **04-09-07, 07:10 PM**

Two in ported LLT sonosubs.

**Jerm357** · **05-30-07, 09:29 PM**

Ported all the way

Heres an unpainted pic so you can see it. It has since been painted with a high gloss black and against my black walls I cant get any good pictures of it now.

Dual RLP 15" 2 ohm DVC with 4 15" passive radiators loaded to 1100 grams each. Re-wired all 4 coils to series wiring, 8 ohms to amp, QSC 1450 bridged to mono. Performs great. Plan to start on another just like it now that I've got a spare QSC amp. Crisp clean lows with the passives. Low volumes or high.

**TheEAR** · **01-26-08, 12:27 AM**

Joining the Sound Splinter club,very soon. RLp 15 in a 13cu ft box,15Hz tuning ...8" port flared to 10" . Next...a second one.

In a 800cu ft room,backed by a dozen other subs.
