DIY Sub Mk.2 RTP-15

[ReTrO]

Lost this first time around so here we go again.

ReTrO & Taz Productions welcome you to another DIY audio masterpiece.

RTP-15

This subwoofer utilises an Adire Audio Temepst 15" bass driver fitted inside the Adire reference small enclosure (65L). The enclosure has been made by Taz, using the latest MDF bonding techniques (involving lots of high voltages, yeah!)

It will be using an unknown amplifer at present, but it will most likely be either a BKElec DT300 plate amp or a pair of BKElec 200w amp modules. In the short term it will use the 110 amp module from the Mk.1 RTP-10 project.

It has a 12 band parametric eq offboard, in the form of a Behringer Feedback Destroyer Pro DSP 1124P , to help with the in-room response.

The enclosure will be finished in black ash fablon, as supplied and fitted by the man Taz himself. I will be making a stretchy sock grill to go over the front.

Here are some pictures so far.

Looks good as always but why the High Q 0.9 design you will be getting a lot more output in the higher bass region, the EQ will help a lot but a mid Q 0.707 or even a lower Q design would probebly sound deeper for home cinema.

Space is an issue here micb3rd. Otherwise I would have gone for much larger box or maybe even an IB design in a wall or door.

I reckon we may be able to get away with a touch of EQ to rbing the bottom end out a bit, though it may not be needed if it can shift the air well.

What about building a sub into the floor?? - with all the box etc below the floorboards and speaker grille recessed into the floor??
I can access below the floor very simply.

This is my setup

That is something I would consider if I owned my own house and had a job.

My HC at home is in a spare bedroom when there's some space. I'm hoping to get a room built ar some point though in me garden if I'm still at home when I have a good job.

It will be to partner it sort of replace it. I've not had the pleasure of using the JL myself because I've been at Uni and the sub's been at Taz's place.

He will be using the Temepest one also for a while. Hope he enjoys it.

Nathan_silly - I was notthinking of anything that extreme!!! May be just a decent sized MDF box with a good sized driver.
