Prefab 18 inch sealed boxes?

[Blackout67]

Tryna find a sealed box for a Stereo Integrity HT-18. O ly one I can find that would be suitable is the Dayton Audio knock down box. But I don't really have the space or tools to put that together. Anyone know of any sturdy sealed 18 boxes for like $250 or less shipped?


Thanks in advance

I have one but I live in a one bed apartment with my girlfriend and a cat so I don't have much room to put together a box. Plus my girlfriend would be pissed

She wasn't too happy when she came home to me gluing on my new headliner in the kitchen

Yea but all I can find are shitty ported ones. No one makes sealed prefabs for 18 inch subs that I can find atleast

Only the mounting diameter is off by 0.06 of an inch.

Those are beefy looking boxes

Called a nearby shop for a quote.. $350 for a double baffled bare MDF wood box, 4.2 cubs with no terminals. Crazy

Level 2. 1.5" baffle and braced as well. They also have Level 1 but it is only $50 less.

Just wanted to give an update. These guys are awesome. Responded to my message on eBay to see if I could get it any cheaper. They're gonna send me an unfinished one for around $230 after shipping vs the listed in for around $310

Highly recommend these guys

Nice. I did not know they would do custom orders.

Me either. Responded quickly and even adding a double baffle without the bracing even tho it's stage 1 and doesn't usually include that

Same price as the PE box and I don't have to put it together. Hopefully it'll be ok without the bracing with just the 1.5 inch baffle. I don't think the HT-18s are very heavy anyways. Maybe 30-40 pounds

I have never used a braced box before. I think only SPL subs would benefit such techniques so no need to worry about it.

Panels larger than 16" in length I like to add bracing. Doesn't even have to go panel to panel just another piece in the middle of the panel either flat against it or like a T.

If I notice any resonance I'll just go ahead and throw some CLD to help out.

Interesting thing I noticed though; when you go to buy the HT-18s, it links you to a PayPal for Sundown Audio. The shipping confirmation email also game from a Sundown Rep. I know both companies are nearby each other and have collaborated in the past, but I didn't know that Sundown made any subs for them. I thought they just provided the baskets and maybe some soft parts. The SQL12 I bought was they SI's website not an external link to Sundown
