RE: Some new gear, can't say I'm impressed

My budget was about £400, so I suppose this was the best I would get for the money.

It's warming on me now, especially the fact I can control everything remotely using my iPhone. I'm a bit dissapointed that there isn't much bass until I increase it on the Dran5, but I can get a subwoofer at a later date to solve that.

Someone said earlier that Amp was 65w x 2 @ 4Ohms, I've checked the speakers and they're good for 4-12 ohms, does that mean I'll get the 65w? will the amp automatically output at 4Ohms?

RE: Some new gear, can't say I'm impressed

If the speakers are 4Ohms you should get 65W but if 8 Ohms you will only get about 35W. Most amps are quoted at 8Ohms I think quoting at 4Ohms is misleading to say the least.

Here's what the documentation for the amp and speakers say...

 

Amplifier

Rated output power 65 W + 65 W (1kHz, 4ohms, 0.7% THD)

Dynamic output power 80 W + 80 W (4 ohms)

Output terminals - Speaker 4 - 16 ohms

 

Speakers

Nominal Impedance 8 ohms

Minimum Impedance 4.1 ohms

Dyn. output I presume is peak power which is just for a short time. What they should quote is continteous power at 8Ohms which I would say is about 35Ws.

Bingo, dont use the bass lift Wink

Why not? does it use additional power?

On a side note, is it possible to buy something which would attach to the speaker cables and boost the power a little? I remember having a car amplifier years ago that did something along those lines?

RE: Some new gear, can't say I'm impressed

Litlened, how loud have you been listening to them? Have you been able to take any db measurements at 1 metre distance from the speakers?

 

Your amp will give about 100 dbs at 1 metre from your speakers before the risk of the amp clipping. That's very loud. But we don't know how loud you've been playing them. It's quite possible that the source, amp and speakers just don't sound very good as a combination at levels above 85 dbs at 1 metre.

 

If you go 2nd hand you can buy some competent amp and speaker combinations for £400 that will sound easily noticeably better than your current system.

 

Also, I have had source and amp combinations where clipping starts with the volume knob at 10 o'clock. And others where the volume knob can be set to maximum without clipping. It's all down to the total system gain - which is down to voltage output from your source and voltage required for maximum output from your amps - and to a lesser degree speaker impedance and ability of the amp to double power as impedance halves. In a way it's a bit similar to car speedometers. My car's speedo goes up to 150mph, but there's no way it can reach that speed unless it's in neutral and going down an 80% hill with a hurricane tail wind.

I don't have a means of measuring the sound level.

I'm going to check again later with the bass boost turned down, and see when the clipping occurs. It may be that I'm just missing a sub-woofer from my setup to keep me happy.

HAve you got your speakers on stands or a shelf or wall?

They're currently sat ontop of a solid wood cabinet, although they will be going on stands when I get around to ordering some.

RE: Some new gear, can't say I'm impressed

Have you double checked the speakers are in phase? in other words the red & black on the back of the amp is to red & black on the speakers if one is the wrong way round you will half your bass - Cable is usually marked with a stripe or ridge on one side of the cable - Its easily missed I have a friend who has faffed with hi-fi for years & nearly bought new speakers until he embarrassingly discovered his speakers were out of phase  :grin:

Worth checking, I find its best to use mono music.

That won't do them any favours either.

RE: Some new gear, can't say I'm impressed

Bass boost is designed to be used at very low volume levels (like a loudness control).

Given the volume levels you are using (40) I am guessing you like it very loud.

[Depending on the source]  I use volume levels between 15 and 28 (with a Marantz M-CR603 rated @ 60 watts into 6 Ohms and used with 89dB speakers). 

The loudest I have played my system is around 85dB - 88dB peaks at 2.5 metres distance but normally lower. (I value my ears and don't enjoy louder volumes anyway.)

I think you are expecting too much volume from what is - essentially - a micro system designed for moderate/reasonable volume levels in small/medium sized rooms with relatively efficient speakers (like the Boston Acoustics A25s made by D&M or the speakers provided by Denon with the N5).

I too would suggest a 'pokier' amp and leave the DBB for what is was designed for (use at very low volume levels).

Yikes!   Stands or wall brackets. Not big hollow pieces of furniture. (Open shelves, at a push, so long as the speakers have front ports or are sealed.)
