I'm in the process of remodeling my living room and plan on doing an IB sub when it is completed. Aside from the PE IB 15's, are there any other inexpensive (under $150) 15" subs that would work good for an IB install? Are the drivers available from Stryke/Lamba delivering yet? Those look pretty decent for $100 ea if you purchase 4 or more.
Another question: What if I use better drivers and go with 2 15's instead of 4 of the less expensive ones. Which way would you guys go?
Any help would be greatly appreciated.

Currently there's not much available at all, let alone any good low buck drivers.
No one's posted about building any IB's using the Stryke drivers so I have to assume they're not being shipped.
The number of drivers in and of itself isn't important it's the amount of air they displace.
New drivers are becoming available from Adire and in a couple of months from Ascendant. But you aren't going to find anything at the $100 for a good 15" price point.

Thanks Thomas. It's funny, I had been planning all along to build one of the Rythmik servos, since we are planning an addition next year. But I finally decided, what the heck, I can always move the IB if I have to. Then I start shopping around for drivers, and I can't find much for choices.  I don't have to go with budget drivers. It's just that I planned on spending no more than $600 on the subs and kind of had my heart set on 4 of them. But if 2 better 15's will yield as good of results as 4 budget 15's, I'm all for it. I was looking at the TC sounds subs that SoundSplinter offers, but for the price, those don't seem too impressive for IB use. The search continues.  |

A pair of the 15" Premium drivers from SS would be fine in an IB.
The Fs is a little high, but EQ can easily fix anything that room gain doesn't fill-in.
Those have double spider and a fairly stiff suspension, so they should take a pounding and not break a sweat...

The Fs is a little high, but EQ can easily fix anything that room gain doesn't fill-in. . The Fs of about 23 hz was my main concern. I don't want to put the money into this thing if it's not impressive below 20 hz. So you think with a little eq I can get reference level sound below 20 hz? My living room is about 12 X 24 X 8' high with the kitchen opening at one end and a hall way on the other. Unfortunately, the seating/listening position has to be on the long side with the 12' dimension being the sides of the room. The amp I will use will either be the Nady or the Behringer (smaller one) that is on the recomended equipment page. BTW, I really appreciate the help you are willing to give on this and other sites. I hate going into something blind and places like this nearly eliminate that happening. |

I just noticed that the Dayton Titanic MKIII has about 60 more liters of Vas and a Fs of 19 hz for about $35 less each than the TC sounds drivers. All these t/s parameters are confusing. For instance, the Dayton IB 15 has 6mm less Xmax than the titanic yet has 3 cubic feet more Vas. Maybe I should just stick with my 10" Athena sub and forget that there is WAY better bass available. Then again, maybe not.  Anyone use the Titanic in an IB yet? Last question: Which would be better; 4 Dayton IB 15's or 2 Titanics/TC sounds Premium 15's? I think I'll go have a beer now.  |

Just FYI, I ordered 4 (more) of the 15 inch AE/Stryke IB woofers from Custom Audio Solutions on August 30 and received them on Tues Oct 4th. At 100.00 a driver, it is a deal worth waiting for, at least for me.

Vas is principally a concern if you have a limited space for the rear wave… but often this isn't as critical when using an adjoining room which has many times the Vas. If you are looking to maximize your cost / performance ratio your should probably concentrate on the cost per litre of displacement. If I were building myself one at this moment, the SoundSplinter RL-P15 would be my driver of choice even though it doesn't have the lowest $/ltr. www3.sympatico.ca/bonaz/IB-Sub/IBdrv-01.htm The SoundSplinter RL-P15 are only a couple of dollars more than the unproven Elemental Design 16Kv.2 and the budget constructed PE/Dayton 15" IB units. (EDIT: following garyk post, it seems like the Acoustic Elegance units have begun shipping again, but the status has been inconsistent) The PE Titanics are clearly more expensive per litre of displacement.

Drivers like this play well below their Fs. Room gain usually fills in the rest. If room gain doesn't do the job a dab of EQ will.
As a example I have one of the original HE-15's in a ported box tuned to 18Hz. The Fs of the HE-15 is 26Hz.
Nope the cost vs displacement ratio is too high

Thanks for the link formica. Very helpfull! Looks like 4 or the AE/Stryke drivers are the way to go if cost per liter is the criterea. John just emailed me today and told me a bunch recently shipped and more are being made as we type. I need to just pull the plug and order something or I'm going to drive myself crazy.  |

Glad to hear the AE drivers are rolling again. I had a few moments earlier this evening - and realized that I had never really plotted my output on my (2) AE IB15 drivers in my IB setup. Lots of fun stuff kept me occupied for the past few months, though. Switching over to the Panasonic XR55 receiver - and setting the receiver to 80 Hz for the crossover meant that I was giving up some EQ capabilities on the receiver level. However, with some of the money saved, it now looks like I'll need to nab a BFD to tone down that spike @ 80Hz as I can hear it each time I listen to music.  |

I've realized this fabulous site doesn't have a F/S section. However, I've posted some gear over at the Home Theater Forum.
- (2) IB 15 subs for $80 + shipping. Price is for each sub.
- (1) Nady XA-1100 Amplifier. $170 + shipping.
If I'm wrong in posting these here, please accept my appologies.
I can receive E-mails messages at: wjepics@cox.net
Thank you.

FWIW I'm thrilled with the performance of my PE IB 15" drivers.

Ok, I'm feeling a bit "boxed-in"  regarding available 15" drivers. I've been scratching my pooh head (think, think, think) and here's what I'm getting: - The 4 driver AE IB15 package is the best value. I feel compelled to wait on the verdict on the "out of spec" issue that is playing out in this forum. The recent backorder problems are also a concern.  This option is a strong possibility but I have reservations. - Ascendant, Adire and Element are not available. My plan is to build the IB-sub in December so I feel compelled to order the drivers soon. Eliminated unless something starts shipping soon. - The Element driver is unproven in an IB.  Eliminated. - The Resonant Engineering website is wacked and the their driver specs are suspect. Eliminated. - The Dayton IB drivers seems to be of a lower build quality but might get the job done. The perfectionist in my would probably always wonder if better drivers would sound better.  Eliminated. - Disregarding the AE IB15s for the moment, the Dayton Titantics, SoundSplinter RL-P15 DVC2, and TC-sounds TC-2+ drivers appear to be my viable near term options. Is this thinking sound? Please advise. Thanks a bunch! PS: My room is 2200 cubic feet and I'm looking for low end extension and low distortion. I am not interested in insane SPLs. |

Seems reasonable.
I'd go with the Oaudio 15"s if you want a very good sytem with good output. I'd go with the RL-p 15"s if you want higher output levels and drivers that can take a pounding. Since the Fs is higher they will require more EQ compared to the TC2+.
