'XXX' mkII

[ShinObiWAN]

Working on a follow up to the XXX, since it has now been sold. I always work on the basis of build the best you can then next time go one better so here I am

This one is sort of a big brother if you like.

I'm still working through design details and then modelling them but I can tell you that it will be 4m long transmission line design featuring a 15" Volt Radial driver.

Rough dimensions at the moment are 100 H x 43 W x 50 D (cm). So its far from small and roughly 2x as large as the original XXX.

More details later.

Sounds like a MONSTER !! Can't wait.

[ShinObiWAN]

Thanks guys.

I know I'm not going to be able to go much deeper, if at all, than the XXX since its in room frequency response was +/-3dB 10hz - 80hz. But the quality of the bass wasn't the best, musically it just wasn't quite right and that was even after EQ.

So this time around I want extension but great musicality. Volt is probably one the most respected manufacturers of hi-end studio grade bass units. So it was an easy choice when deciding to use their 15" Radial driver over the typical and impressive brute force subs such as the Tumult etc.

Hopefully I can get building the box next week sometime.

Okay more details here:

• Driver: 15" Volt 'Radial' R3853 - £380 from here

• Amp: BK BSBP500 500w subpanel - £220 from here

• Cabinet: 3 x 25mm MDF 8ftx4ft Sheet - £45

Total Cost is around £650 for an unfinished bare MDF enclosure. Finishing could then cost as little as £20 for fablon, £30-50 for spray finish or around £100 for real wood veneering.

Personally I plan to cover the sides, top and bottom in hard wearing black/grey fablon and then spray the front and rear black. This of course could change but its how I see it at the moment.

Ordered the Volt driver already but have been told there is a 2-3 week wait whilst Volt build some more I guess. Its on order anyway. MDF is also sat up in the shed ready for some cutting

PS. Anyone interested in a BSBP100 sub amp, £80inc?

The BSB500 is great for AV, however, I found there were better alternatives if musicality was high on the list of requirements.

Many thanks Gary,

Always open to opinions and other options. Luckily I haven't ordered the amp yet so the door is still open for change.

Musicality is high on my list so the Hypex is definitely on my mind. Is there any other UK distributors other than design3dw?

[GaryG]

Not that I'm aware of. Here's their website with a list of distributors.

Gary do you have any experience with the DT300?

Good price at £155 and it looks like its more highly rated than the BK for SQ.

The Radial is an 8ohm nominal load and it looks like the output of the DT300 is around 200w at this level. Would like a little more power on tap and the next step up would be the Hypex HS500 which is way over budget nearly £500.

Hmm decisions

[GaryG]

Sorry, no I haven't. It's been a few years since I posted those comments and I've moved on from plate amps.

If you want something to do for the next 3 weeks while you wait for delivery of the Volt driver I've got a Hypex HS200, an Adire Shiva and a 3ft tube that you can play with, I've also got a spare Tumult knocking about as well. You'd have to come and fetch them though.

Gary, I've sent you a PM regarding the above.

Driver has arrived today

[Mat-Moo]

Looks like a jet engine in the first!

Wow, beast & an a half..........can't wait to see how this project turns out.

I believe Quested use these drivers in their reference 5.1 monitoring installations.
If it is indeed the same driver, I've mixed on a system using 3 of them many a time and the LF response is staggering (totally dedicated studio of course but the extension is seismic when needed)

Should be fun in a domestic situation!!!
