Looking for a new SQL driver

[Somchine13 10+ year member]

Currently owned Stereo Integrity SQL, Adire Brahma, and RF power T1. I’m looking for another good sound quality subwoofer to play with and came across ID Max, are the ID Max similar to the the SI SQL? I’m also looking at the W7 but not sure if the price tag is worth it. Any other brand suggestions would be great as well.

eBay if you're in a hurry.

Peerless by Tymphany STW-350F 15" Subwoofer 3500W RMS NEW(OPEN BOX) | eBay

Brand new, just taken out of the box to take pictures. These are monster subwoofers made for small enclosures wirh their 7.4" voice coils, and use a lot of power for brute force. I intend to make a pair of awesome DIY home theater subs but never got around to it. 3500w RMS, so they need a big amp.

I did two of these ported in a home theater build and they are pretty impressive drivers. 7.5" VC, 3500 watt SQL air pumps! THis is terrible recording where the mic obviously can't handle the output but it gives you an idea!



Don't let the xmax fool you. Read up on this driver, really pretty impressive all the way around.

Wow, sub looks good. I’m definitely looking it.

The w7 isn't worth the price tag. Idk what you didn't like about the Brahma and SQL those are pretty much the top end sound quality loud drivers.

You can always go for a pure sq driver with more cone area but the gains are usually negligible. Maybe in or truck baffle with a pair of 15s or 18s

Those peerless subs are what the Memphis viv is based off of if you want the same sub from a car audio company

Granted, but it's also almost twice the price. You could land two stateside for the price of one Viv14.

I agree, not sure what wasn’t liked about the Brahma, I’d take one over the others easily. The issue with the peerless sub is if it ever blows, I don’t know if recone kits exists but good luck finding a coil that size. If you had to pay precision econo wind to make that size coil it would probably cost as much as a new sub .

I’ve always liked the way a w7 12 and 13.5 sound sealed but the prices have gotten insane! The idmax is a nice sub but isn’t my cup of tea. I’m a big fan of tc sounds subs but of course that requires going used. I’ve built subs for others and have gotten lucky with guys who have had some blown tc sounds subs I took as partial trade. Love when that happens rebuilt 3Hp 12” and 15”. These sounded amazing!

What kind of enclosures did you use for the SQL and Brahma?

 

[Somchine13 10+ year member]

Ported to 32-34 hz around there. I like both subs, just want to play with something new.

Don't let the xmax fool you. Read up on this driver, really pretty impressive all the way around.

Funny xmax spec. Clearly the driver is capable of more.

Xmax is only linear movement from there to xmech you cave the travel that induces distortion.

This driver is capable of 45.5 mm of excursion before any major loss in motor strength (Bl). In other words, this driver is capable of 90 mm (3.5") peak to peak excursion while still producing low distortion output.

Nice...

And big (diameter) coils seem to perform better at their BL limits (ie Dyn & Morel midbass drivers).

It was a few years ago but built two HT subs using these, each fed with a kilowatt plate amp, the low end output would raise the hair on your arms, make your heart skip a beat, pretty impressive.

 

[djdilliodon!]

The peerless sub has a winding width of 2.25”. Not accounting for top plate thickness, that’s 28.5mm of xmax mathematically calculated, with top plate thickness accounted for its probably around 20mm realistically mathematically.

 

[Doxquzme Premium Member]

I don't recall the particulars, but 3.5" top to bottom travel is the linear movement, before being affected or distorting. I'd have to find the articles that discuss it, but that is pretty well documented.

 

[Marve_Lous]

I love my IDMAX 12. Have it in about 1.6 sealed. Bass sounds nice and warm. I’ve been wanting to grab another.

That is mechanical movement, not linear. The mathematical calculation is the best way, that is the coil still in the gap (some may add 10-15%). Mechanical movement is when it comes to damage (coil hitting the backplate). Many use this spec along with peak to peak to make a sub appear to have a lot of xmax. The data sheet that shows xmax at 10.4mm may be accurate depending on how thick the top plate is. Looking at the coil again, the 2.25” is the actual full length of coil, not the windings so that spec is probably accurate. The 10.4mm is also mentioned on partsexpress as well.
